Be sure to wear adequate personal protection equipment (protection gloves, safety glasses, ...) when performing installation, maintenance or service to the unit. If not sure of installation procedures or operation of the unit, always contact your local dealer for advice and information. Improper installation or attachment of equipment or accessories could result in electric shock, short-circuit, leaks, fire or other damage to the equipment. Be sure only to use accessories and optional equipment made by Daikin which are specially designed for use with the products as of subject in this manual and have them installed by an installer. The precautions listed here are divided into the following four types. They all cover very important topics, so be sure to follow them carefully. DANGER: ELECTRICAL SHOCK AL Switch off all power supply before removing the switch box service panel or before making any connections or touching electrical parts. Do not touch any switch with wet fingers. Touching a switch with wet fingers can cause electrical shock. Before touching electrical parts, turn off all applicable power supply. To avoid electric shock, be sure to disconnect the power supply 1 minute or more before servicing the electrical parts. Even after 1 minute, always measure the voltage at the terminals of main circuit capacitors or electrical parts and, before touching, be sure that those voltages are 50 V DC or less. When service panels are removed, live parts can easily be touched by accident. Never leave the unit unattended during installation or servicing when the service panel is removed. ASSS DANGER: DO NOT TOUCH PIPING AND INTERNAL PARTS Do not touch the refrigerant piping, water piping or internal parts during and immediately after operation. The piping and internal parts may be hot or cold depending on the working condition of the unit. Your hand may suffer burns or frostbite if you touch the piping or internal parts. To avoid injury, give the piping and internal parts time to return to normal temperature or, if you must touch them, be sure to wear protective gloves. At WARNING ■ Tear apart and throw away plastic packaging bags so that children will not play with them. Children playing with plastic bags face danger of death by suffocation. ■ Safely dispose of packing materials. Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries. Installation manual DA/K/N EBH0006+008BAV3 2 Unit for air to water heat pump system 4Pw64602-1 D - 12.2010 ■ Ask your dealer or qualified personnel to carry out installation work. At not install the machine by yourself. Improper installation may result in water leakage, electric shocks or fire. ■ Perform installation work in accordance with this installation manual. Improper installation may lead to water leakage, electric shocks or fire. ■ Be sure to use only the specified accessories and parts for installation work. Failure to use the specified parts may result in water leakage, electric shocks, fire, or the unit falling. ■ Install the unit on a foundation that can withstand its weight. ■ Insufficient strength may result in the fall of equipment and causing injury. ■ Carry out the specified installation work in consideration of strong winds, hurricanes, or earthquakes. Improper installation work may result in accidents due to fall of equipment. ■ Make certain that all electrical work is carried out by qualified personnel according to the applicable legislations and this installation manual, using a separate circuit. Insufficient capacity of the power supply circuit or improper electrical construction may lead to electric shocks or fire. ■ Be sure to install an earth leakage circuit breaker in accordance with the applicable legislations. Failure to do so may cause electrical shock and fire. ■ Make sure that all wiring is secure, using the specified wires and ensuring that external forces do not act on the terminal connections or wires. Incomplete connection or fixing may cause a fire. ■ When wiring between the indoor and the outdoor units and wiring the power supply, form the wires so that the panels can be securely fastened. If the panels are not in place, overheat of the terminals, electric shocks or a fire may be caused. ■ After completing the installation work, check to make sure that there is no leakage of refrigerant gas. ■ Never directly touch any accidental leaking refrigerant. This could result in severe wounds caused by frostbite. ■ Electrical work must be carried out in accordance with the installation manual and the national electrical wiring rules or code of practice. Insufficient capacity or incomplete electrical work may cause electrical shock or fire. ■ Be sure to use a dedicated power circuit. Never use a power circuit shared by another appliance. ■ For wiring, use a cable long enough to cover the entire distance with no connection. Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit. Failure to do so may cause abnormal heat, electric shock, or fire. ■ Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be hot or cold, depending on the condition of the refrigerant flowing through the refrigerant piping, compressor and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to wear proper gloves. CAUTION ■ For use of units in applications with temperature alarm settings it is advised to foresee a delay of 10 minutes for signalling the alarm in case the alarm temperature is exceeded. The unit may stop for several minutes during normal operation for "defrosting of the unit' or when in "thermostat -stop" operation. ■ Earth the unit. Earth resistance should be according to the applicable legislations. Do not connect the earth wire to gas or water pipes, lightning conductor or telephone earth wire. Incomplete earthing may cause electric shocks. Gas pipe. Ignition or explosion may occur if the gas leaks. Water pipe. Hard vinyl tubes are not effective earths. Lightning conductor or telephone earth wire. Electric potential may rise abnormally if struck by a lightning bolt. ■ Install the indoor and outdoor units, power wire and connecting wire at least 1 meter away from televisions or radios to prevent image interference or noise. (Depending on the radio waves, a distance of 1 meter may not be sufficient to eliminate the noise.) ■ Do not rinse the unit. This may cause electric shocks or fire. ■ Do not install the unit in places such as the following Where there is mist of mineral oil, oil spray or vapour. Plastic parts may deteriorate, and cause them to fall out or water to leak. Where corrosive gas, such as sulphurous acid gas, is produced. Corrosion of copper pipes or soldered parts may cause the refrigerant to leak. Where there is machinery which emits electromagnetic waves. Electromagnetic waves may disturb the control system, and cause malfunction of the equipment. Where flammable gases may leak, where carbon fibre or ignitable dust is suspended in the air or where volatile flammables, such as thinner or gasoline, are handled. Such gases may cause a fire. Where the air contains high levels of salt such as that near the ocean. Where voltage fluctuates a lot, such as that in factories. In vehicles or vessels. Where acidic or alkaline vapour is present.

CAUTION Appliance not accessible to the general public, install it in a secured area, protected from easy access. This unit is suitable for installation in a commercial and light industrial environment. General precautions on outdoor installation location Refer to "2. General Safety precautions" on page 2. Select an installation site that meets the following requirements and that meets with your customer's approval. ■ The unit is designed to be installed in an outdoor location. ■ The space around the unit is adequate for maintenance and servicing (refer to 7.2. Service space of the outdoor unit" on page 9). ■ The space around the unit allows for sufficient air circulation. There must be sufficient space for air passage and no obstructions around the air intake and the air exhaust (see "Installing near a wall or obstacle" on page 8). ■ There must be sufficient space for carrying the unit into and out of the site. ■ There is no danger of fire due to leakage of inflammable gas. The site must be free from the possibility of flammable gas leakage in a nearby place. ■ The equipment is not intended for use in a potentially explosive atmosphere. ■ Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified. ■ All piping lengths and distances have been taken into consideration. Requirement Maximum allowable distance between the domestic hot water tank and the outdoor unit (only for installations with a domestic hot water tank installed). The thermistor cable torn supplied with the domestic hot water tank is 12 m in length (to be connected to the indoor unit EKCB). Maximum allowable distance between the torn 3-way valve and the outdoor unit (only for (try to keep as close to installations with a domestic hot water tank the outdoor unit as installed) possible) ■ Since drain flows out of the unit, do not place anything under the unit which must be kept away from moisture. ■ Take care that in the event of a water leak, water cannot cause any damage to the installation space and surroundings (e.g. in case of a blocked drain pipe). ■ Install the unit and power cords at least 3 m away from television and radio sets. This is to prevent interference to images and sounds. Depending on radio wave conditions, electromagnetic interference may still occur even if installed more than 3 m away. EBHQ006+008BAV3 DA/K/N Installation manual Unit for air to water heat pump system 7 4PW64602-1 D—12.2010 ■ Select the location of the unit in such a way that the sound generated by the unit does not disturb anyone, and the location is selected according the applicable legislation. Although the noise produced by the unit during operation is low, avoid installation near to places where even low noise levels can be disturbing (e.g., bedroom windows, terraces, next -door neighbours). ■ Do not install the unit in places often used as workplace. In case of construction works (e.g. grinding works) where a lot of dust is created, the unit must be covered. ■ Be sure that sufficient precautions are taken, in accordance with the applicable legislations, in case of refrigerant leakage. Wheater dependent precautions ■ Select a place where the rain can be avoided as much as possible. ■ In heavy snowfall areas, it is very important to select an installation site where the snow will not affect the unit. If lateral snowfall is possible, Be sure that the heat exchanger coil is not affected by the snow (if necessary construct a lateral canopy). ■ Ensure that water cannot cause any damage to the location by adding water drains to the foundation and prevent water traps in the construction. ■ Do not install the unit in areas where the air contains high levels of salt such as that near the ocean, corrosion may shorten the life of the unit. ■ Prevent direct exposure to winds coming from the sea. ■ Be sure that the air inlet and outlet of the unit are not positioned towards the main wind direction. frontal wind will disturb the operation of the unit. If necessary, use a screen to block the wind. ■ When installing the unit in a place exposed to strong wind, pay special attention to the following. Strong winds of 5 m/sec or more blowing against the unit's air outlet cause short circuit (suction of discharge air), and this may have the following consequences: deterioration of the operational capacity, frequent frost acceleration in heating operation, disruption of operation due to rise of high pressure, when a strong wind blows continuously on the face of the unit, the fan can start rotating very fast until it breaks. Refer to the figures for installation of this unit in a place where the wind direction can be foreseen. - Turn the air outlet side toward the building's wall, fence or screen. Make sure there is enough room to do the installation ■ Set the outlet side at a right angle to the direction of the wind. Strong wind Blown air Strong wind Selecting an outdoor location in cold climates ONOTICE When operating the unit in a low outdoor ambient temperature, be sure to follow the instructions described below. ■ To prevent exposure to wind, install the unit with its suction side facing the wall. ■ Never install the unit at a site where the suction side may be exposed directly to wind. ■ To prevent exposure to wind, install a baffle plate on the air discharge side of the outdoor unit. ■ When installing the unit in a place frequently exposed to snow, pay special attention to the following: Elevate the foundation as high as possible. Select an installation site where the snow will not affect the unit. If lateral snowfall is possible, make sure that the heat exchanger coil is not affected by the snow (if necessary construct a lateral canopy). Construct a large canopy. Construct a pedestal. Install the unit high enough off the ground to prevent burying in snow. Place of installation ■ Prepare a water drainage channel around the outdoor unit, to drain waste water from around the unit. ■ If the water drainage of the unit is not easy, please build up the unit on a foundation of concrete blocks, etc. (the height of the foundation should be maximum 150 mm). ■ If you install the unit on a frame, please install a waterproof plate within 150 mm of the underside of the unit in order to prevent the invasion of water from the lower direction. ■ If you install the unit on a building frame, please install a waterproof plate (field supply)(within 150 mm of the underside of the unit) in order to avoid the drainwater dripping. (See figure). ONOTICE Units cannot be installed hanging from the ceiling or stacked. ■ Installing near a wall or obstacle Where a wall or other obstacle is in the path of the unit's air intake or exhaust airflow, the distances as indicated on the figures below need to be respected.

It is best to screw in the foundation bolts until their n length remains 20 mm above the foundation surface. ONOTICE ■ Prepare a water drainage channel to drain waste water from around the unit. During heating operation and when the outdoor temperatures are negative, the drained water from the outdoor unit will freeze up. If the water drainage is not taken care of, the area around the unit might be very slippery. ■ When installed in a corrosive environment, use a nut with Im plastic washer (1) to protect the rM nut tightening part from rust. Ek 1 Heater kit installation (optional) Refer to the installation manual of the EKMBUH heater kit for more details. 9.5. Drain work of the outdoor unit In case drain work on your outdoor unit is neccessary, follow the guidelines below. ■ Two drain outlets are provided in the bottom plate of unit (drain plug and drain hose are field supply). ■ In cold areas, do not use a drain hose with the unit. Otherwise, drain water may freeze and block the drain. In case the use of a drain hose is unavoidable for one reason or another, it is recommended to install a heater tape in order to protect drain from freezing. ■ Make sure the drain works properly. ONOTICE If drain holes of the outdoor unit �� o are covered by a mounting base o or by floor surface, raise the unit in order to provide a free space of more than 100 mm under the outdoor unit. 913 322 1 1 I/r� +2 III l 1 Drain water holes 2 Bottom frame Installation manual DA/K/N EBH0006+008BAV3 1 O Unit for air to water heat pump system 4Pw64602-1 D - 12.2010 10. PIPING CONNECTION WORK 10.1. Checking the water circuit The units have a water inlet and water outlet for connection to a water circuit. This circuit must be provided by a licensed technician and must comply with all applicable legislations. ONOTICE The unit is only to be used in a closed water system. Application in an open water circuit can lead to excessive corrosion of the water piping. Before continuing the installation of the unit, beware of the following points: ■ Two shut-off valves are delivered with the unit. To facilitate service and maintenance, install one at the water inlet and one at the water outlet of the unit. ■ Drain taps must be provided at all low points of the system to permit complete drainage of the circuit. Two drain valves are provided inside the unit. ■ Air vents must be provided at all high points of the system. The vents should be located at points which are easily accessible for servicing. An automatic air purge is provided inside the outdoor unit. Check that this air purge valve is not tightened too much so that automatic release of air in the water circuit remains possible. ■ Take care that the components installed in the field piping can withstand the water pressure (maximum 3 bar + static pressure of the pump). ■ The maximum waterpiping temperature is 65°C according to safety device setting. ■ Always use materials which are compatible with the water used in the system and with the materials used in the unit. ■ Select piping diameter in relation to required water flow and available external static pressure (ESP) of the pump. The recommended water piping diameter is 1". ■ The minimum required water flow for the unit operation is 12 I/min. When the water flow is lower than this minimum value, flow error IH will be displayed and the operation of the unit will be stopped. ONOTICE It is strongly recommended to install an additional filter on the heating water circuit. Especially to remove metallic particles from the field heating piping, it is advised to use a magnetic or cyclone filter which can remove small particles. Small particles can damage the unit and will not be removed by the standard filter of the heat pump unit. 10.2. Checking the water volume and expansion vessel pre -pressure The unit is equipped with an expansion vessel of 6 litre which has a default pre -pressure of 1 bar. To assure proper operation of the unit, the pre -pressure of the expansion vessel might need to be adjusted and the minimum and maximum water volume must be checked. 1 Check that the total water volume in the installation, excluding the internal water volume of the outdoor unit, is 10 1 minimum. Refer to "Technical specifications" on page 18 to know the internal water volume of the outdoor unit. OINFORMATION In most applications this minimum water volume will have a satisfying result. In critical processes or in rooms with a high heat load though, extra water volume might be required. ONOTICE When circulation in each space heating loop is controlled by remotely controlled valves, it is important that this minimum water volume is kept even if all the valves are closed. See example below. The maximum allowed water volume is 2501 (if no glycol is used). This is reduced to 175 1 if 25% of propyleen glycol is used. In case no EKMBUHBA6V3 backup heater kit is installed, the maximum allowed water volume is restricted to 150 I. In such case we recommend the use of a thermostatic by-pass valve (see example below). As soon as the water circuit with the outdoor unit is in normal operation range, this by-pass valve will gradually open, so the entire circuit is than gradually heated.

If this is not the case, the expansion vessel inside the unit is too small for the installation. 2.5 2 ca A C s (D a 1 n B . 0.5 0.3 010 50 100 150 260 250 300 350 400 450 maximum water volume [I] pre -pressure = Pre -pressure maximum water volume = Maximum water volume A = System without glycol B = System with 25 % propyleen glycol c = With EKMBUH unit only Example 1 The outdoor unit is installed 5 m below the highest point in the water circuit. The total water volume in the water circuit is 100 1 In this example, no action or adjustment is required. Example 2 The outdoor unit is installed 4 m below the highest point in the water circuit. The total water volume in the water circuit is 190 I. Result: ■ Since 1901 is higher than 1701, the pre -pressure must be decreased (see table above). ■ The required pre -pressure is: Pg = (H/10 + 0.3) bar = (4/10 + 0.3) bar = 0.7 bar ■ The corresponding maximum water volume can be read from the graph: approximately 200 I. ■ Since the total water volume (190 1) is below the maximum water volume (200 1), the expansion vessel suffices for the installation. 10.3. Setting the pre -pressure of the expansion vessel When it is required to change the default pre -pressure of the expansion vessel (1 bar), keep in mind the following guidelines: ■ Use only dry nitrogen to set the expansion vessel pre -pressure. ■ Inappropriate setting of the expansion vessel pre -pressure will lead to malfunction of the system. Therefore, the pre -pressure should only be adjusted by a licensed installer. 10.4. Connecting the water circuit Water connections must be made in accordance with all applicable legislations and the outlook drawing delivered with the unit, respecting the water in- and outlet. ONOTICE Be careful not to deform the unit piping by using excessive force when connecting the piping. If dirt gets in the water circuit, problems may occur. Therefore, always take into account the following when connecting the water circuit: ■ Use clean pipes only. ■ Hold the pipe end downwards when removing burrs. ■ Cover the pipe end when inserting it through a wall so that no dust and dirt enter. ■ Use a good thread sealant for the sealing of the connections. The sealing must be able to withstand the pressures and temperatures of the system, it must also be resistant to the used glycol in the water. ■ When using non -brass metallic piping, make sure to insulate both materials from each other to prevent galvanic corrosion. ■ Because brass is a soft material, use appropriate tooling for connecting the water circuit. Inappropriate tooling will cause damage to the pipes. ■ Increasing the distance between shut-off valves is necessary for ease of installation. Installation example 1 To secure the piping of the unit 2 To connect the shut-off valve 3 Water outlet 4 Water intlet 5 Round socket 2x 1" FBSP (field supply) 6 1" MBSP pipe end (field supply) Installation manual DA/K/N EBH0006+008BAV3 12 Unit for air to water heat pump system 4Pw64602-1 D - 12.2010 ONOTICE ■ The unit is only to be used in a closed water system. Application in an open water circuit can lead to excessive corrosion of the water piping. ■ Never use Zn-coated parts in the water circuit. Excessive corrosion of these parts may occur as copper piping is used in the unit's internal water circuit. ■ When using a 3-way valve in the water circuit. Preferably choose a ball type 3-way valve to guarantee full separation between domestic hot water and floor heating water circuit. ■ When using a 3-way valve or a 2-way valve in the water circuit. The recommended maximum changeover time of the valve should be less than 60 seconds. 10.5. Protecting the water circuit against freezing Frost can damage the unit. As this unit is installed outdoors and thus the hydraulic system is exposed to freezing temperatures, care must be taken to prevent freezing of the system. All hydraulic parts are insulated to reduce heat loss. Insulation must be foreseen on the field piping. The unit is already equipped with several features to prevent freezing. ■ The software contains special functions using pump and back up heater (optionally) to protect the complete system against freezing. This function will only be active when the unit is off. However in case of power failure, above mentioned features can not protect the unit from freezing. If power failure can happen at times the unit is unattended, Daikin recommends adding glycol to the water system. Refer to Caution: "Corrosion of the system due to presence of glycol" on page 13 Refer to "[4-04] Freeze protection function" in the EKCB installation manual. Depending on the expected lowest outdoor temperature, make sure the water system is filled with a weight concentration of glycol as mentioned in the table below. Minimum outdoor temperature Glycol -5°C 10 -10°C 15% -15°C 20 -20oC 25 -25°C 30 Q CAUTION Units without backup heater kit installed are obligatory always to use glycol. Q WARNING (a) ETHYLENE GLYCOL IS TOXIC (b) The concentrations mentioned in the table above will not prevent the medium from freezing, but prevent the hydraulics from bursting. (c) The maximum allowed water volume is then reduced according to the figure "Checking the maximum allowed water volume" on page 12 Q CAUTION ■ For installations with a domestic hot water tank, the use of propylene glycol, including necessary inhibitors, is only allowed if classified as Category 3 according to EN1717 or the applicable legislations. ■ In case of over -pressure when using glycol, be sure to connect the safety valve to a drain pan in order to recover the glycol. Connecting a drain pipe is not required if no glycol is used. The discharged water is then drained via the bottom of the unit. Q CAUTION Corrosion of the system due to presence of glycol Uninhibited glycol will turn acidic under the influence of oxygen. This process is accelerated by presence of copper and at higher temperatures. The acidic uninhibited glycol attacks metal surfaces and forms galvanic corrosion cells that cause severe damage to the system. It is therefore of extreme importance: ■ that the water treatment is correctly executed by a qualified water specialist; ■ that a glycol with corrosion inhibitors is selected to counteract acids formed by the oxidation of glycols; ■ that in case of an installation with a domestic hot water tank, only the use of propylene glycol, including necessary inhibitors classified as Category 3 according to EN1717 or equivalent based on the applicable legislations is allowed. In other installations the use of ethylene glycol is permitted as well; ■ that no automotive glycol is used because their corrosion inhibitors have a limited lifetime and contain silicates which can foul or plug the system; ■ that galvanized piping is not used in glycol systems since its presence may lead to the precipitation of certain components in the glycolis corrosion inhibitor; ■ that it has to be made sure the glycol is compatible with the used materials in the system. ONOTICE Be aware of the hygroscopic property of glycol: it absorbs moisture from its environment. Leaving the cap off the glycol container causes the concentration of water to increase. The glycol concen- tration is then lower than assumed. And in consequence, freezing can happen after all. Preventive actions must be taken to ensure minimal exposure of the glycol to air. Also refer to "Pre -run checks" on page 15. EBHQ006+008BAV3 DA/K/N Installation manual Unit for air to water heat pump system 13 4Pw64602-1 D - 12.2010 10.6. Initial start-up at low ambient temperatures ONOTICE To ensure that the unit operates within its operating range as soon as possible (water temperature >30oC), the load during start-up must be reduced as much as possible. For example you can do this by putting off fans of the fan coil unit until the water temperature has increased to 30oC. If no backup heater (EKMBUHBA6C3) is installed within the unit we recommend to start-up the unit with a minimum water temperature of 5°C. For floor heating applications without a backup heater installed, start-up circuit by circuit by using an (thermo- static) bypass valve, make sure that the temperature of the water returning to the unit is more than 20oC. 10.7. Charging water 1 Connect the water supply to a drain and fill valve (see "5.2. Main components of the outdoor unit" on page 6). 2 Make sure the automatic air purge valve is open (at least 2 turns). 3 Fill with water until the manometer indicates a pressure of approximately 2.0 bar. Remove air in the circuit as much as possible using the air purge valves. Air present in the water circuit might cause malfunctioning of the backup heater (if applicable). 4 Check that the backup heater vessel (EKMBUH) (if applicable) is filled with water by opening the pressure relief valve. Water must flow out of the valve. ONOTICE ■ During filling, it might not be possible to remove all air in the system. Remaining air will be removed through the automatic air purge valves during first operating hours of the system. Additional filling with water afterwards might be required. ■ The water pressure indicated on the manometer will vary depending on the water temperature (higher pressure at higher water temperature). However, at all times water pressure should remain above 1 bar to avoid air entering the circuit. ■ The unit might dispose some excessive water through the pressure relief valve. ■ Water quality must be according EN directive 98/83 EC. If no glycol is in the system in case of a power supply failure or pump operating failure, drain the system. When water is at standstill inside the system, freezing is very likely to happen and damaging the system in the process. Piping insulation The complete water circuit, inclusive all piping, must be insulated to prevent condensation during cooling operation and reduction of the heating and cooling capacity as well as prevention of freezing of the outside water piping during winter time. The thickness of the sealing materials must be at least 13 mm with k=0.039 W/mK in order to prevent freezing on the outside water piping. If the temperature is higher than 30oC and the humidity is higher than RH 80%, then the thickness of the sealing materials should be at least 20 mm in order to avoid condensation on the surface of the sealing. Water piping freezing prevention Protect the water piping against water freezing during the winter period (e.g. by using an external field supplied heater tape or glycol solution). 11.
