After completing the installation, make sure that the unit operates properly during the startup operation. Instruct the user on how to operate and maintain the unit. Inform users that they should store this installation manual with the operation manual for future reference. Always use a licensed installer or contractor to install this product. Improper installation can result in water or refrigerant leakage, electric shock, fire, or explosion. Meanings of DANGER, WARNING, CAUTION, and NOTE Symbols: 0 DANGER ......••••• Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Qi, WARNING ......••• Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. 0 CAUTION ......•••• Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices. Qi, NOTE ............•••• Indicates situations that may result in equipment or property -damage accidents only. Qt, DANGER • Refrigerant gas is heavier than air and replaces oxygen. A massive leak can lead to oxygen depletion, especially in basements, and an asphyxiation hazard could occur leading to serious injury or death. • Do not ground units to water pipes, gas pipes, telephone wires, or lightning rods as incomplete grounding can cause a severe shock hazard resulting in severe injury or death. Additionally, grounding to gas pipes could cause a gas leak and potential explosion causing severe injury or death. • If refrigerant gas leaks during installation, ventilate the area immediately. Refrigerant gas may produce toxic gas if it comes into contact with fire. Exposure to this gas could cause severe injury or death. • After completing the installation work, check that the refrigerant gas does not leak throughout the system. • Do not install unit in an area where flammable materials are present due to risk of explosions that can cause serious injury or death. • Safely dispose all packing and transportation materials in accordance with federal/state/local laws or ordinances. Packing materials such as nails and other metal or wood parts, including plastic packing materials used for transportation may cause injuries or death by suffocation. Q WARNING • Only qualified personnel must carry out the installation work. Installation must be done in accordance with this installation manual. Improper installation may result in water leakage, electric shock, or fire. • When installing the unit in a small room, take measures to keep the refrigerant concentration from exceeding allowable safety limits. Excessive refrigerant leaks, in the event of an accident in a closed ambient space, can lead to oxygen deficiency. • Use only specified accessories and parts for installation work. Failure to use specified parts may result in water leakage, electric shock, fire, or the unit falling. • Install the air conditioner or heat pump on a foundation strong enough that it can withstand the weight of the unit. A foundation of insufficient strength may result in the unit falling and causing injuries. • Take into account strong winds, typhoons, or earthquakes when installing. Improper installation may result in the unit falling and causing accidents. 1 ■English • Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried out by qualified personnel according to local, state, and national regulations. An insufficient power supply capacity or improper electrical construction may lead to electric shock or fire. • Make sure that all wiring is secured, that specified wires are used, and that no external forces act on the terminal connections or wires. Improper connections or installation may result in fire. • When wiring, position the wires so that the electrical wiring box cover can be securely fastened. Improper positioning of the electrical wiring box cover may result in electric shock, fire, or the terminals overheating. • Before touching electrical parts, turn off the unit. • The circuit must be protected with safety devices in accordance with local and national codes, i.e. a circuit breaker. • Securely fasten the outdoor unit terminal cover (panel). If the terminal cover/panel is not installed properly, dust or water may enter the outdoor unit causing fire or electric shock. • When installing or relocating the system, keep the refrigerant circuit free from substances other than the specified refrigerant (R410A) such as air. Any presence of air or other foreign substance in the refrigerant circuit can cause an abnormal pressure rise or rupture, resulting in injury. • Do not change the setting of the protection devices. If the pressure switch, thermal switch, or other protection device is shorted and operated forcibly, or parts other than those specified by Daikin are used, fire or explosion may occur. 0 CAUTION • Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock. • Do not allow children to play on or around the unit to prevent injury. • The heat exchanger fins are sharp enough to cut. To avoid injury wear gloves or cover the fins while working around them. • 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. • Install drain piping to ensure proper drainage. Improper drain piping may result in water leakage and property damage. • Insulate piping to prevent condensation. • Be careful when transporting the product. • Do not turn off the power immediately after stopping operation. Always wait for at least 5 minutes before turning off the power. Otherwise, water leakage may occur. • Do not use a charging cylinder. Using a charging cylinder may cause the refrigerant to deteriorate. • Refrigerant R410A in the system must be kept clean, dry, and tight. (a) Clean and Dry -- Foreign materials (including mineral oils such as SUNISO oil or moisture) should be prevented from getting into the system. (b) Tight -- R410A does not contain any chlorine, does not destroy the ozone layer, and does not reduce the earth's protection again harmful ultraviolet radiation. R410A can contribute to the greenhouse effect if it is released. Therefore take proper measures to check for the tightness of the refrigerant piping installation. Read the chapter Refrigerant Piping Work and follow the procedures. • Since R410A is a blend, the required additional refrigerant must be charged in its liquid state. If the refrigerant is charged in a state of gas, its composition can change and the system will not work properly. • The indoor unit is for R410A. See the catalog for indoor models that can be connected. Normal operation is not possible when connected to other units. • Remote controller (wireless kit) transmitting distance can be shorter than expected in rooms with electronic fluorescent lamps (inverter or rapid start types). Install the indoor unit far away from fluorescent lamps as much as possible. • Indoor units are for indoor installation only. Outdoor units can be installed either outdoors or indoors. • Do not install the air conditioner or heat pump in the following locations: (a) Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen. Plastic parts may deteriorate and fall off or result in water leakage. (b) Where corrosive gas, such as sulfurous acid gas, is produced. Corroding copper pipes or soldered parts may result in refrigerant leakage. (c) Near machinery emitting electromagnetic waves. Electromagnetic waves may disturb the operation of the control system and cause the unit to malfunction. (d) Where flammable gas may leak, where there is carbon fiber, or ignitable dust suspension in the air, or where volatile flammables such as thinner or gasoline are handled. Operating the unit in such conditions can cause a fire. • Take adequate measures to prevent the outdoor unit from being used as a shelter by small animals. Small animals making contact with electrical parts can cause malfunctions, smoke, or fire. Instruct the user to keep the area around the unit clean. Q NOTE • The outdoor unit should be positioned where the unit and power supply wires (breaker panel to outdoor unit) are at least 1 Oft (3m) away from any televisions or radios. (The unit may cause interference with the picture or sound.) Depending on the radio waves, a distance of 1 Oft (3m) may not be sufficient to eliminate the noise. • Dismantling the unit, treatment of the refrigerant, oil and additional parts must be done in accordance with the relevant local, state, and national regulations. • Do not use the following tools that are used with conventional refrigerants: gauge manifold, charge hose, gas leak detector, reverse flow check valve, refrigerant charge base, vacuum gauge, or refrigerant recovery equipment. • If the conventional refrigerant and refrigerator oil are mixed in R410A, the refrigerant may deteriorate. • This air conditioner or heat pump is an appliance that should not be accessible to the general public. • As design pressure is 604 psi, the wall thickness of field - installed pipes should be selected in accordance with the relevant local, state, and national regulations.

Pressure test and evacuating system w` Q! WARNING • Make sure that air or any matter other than refrigerant (R410A) does not get into the refrigeration cycle. • If refrigerant gas leaks should occur, ventilate the room as soon and as much as possible. • R410A, as well as other refrigerants, should always be recovered and never be released directly into the environment. • Use a vacuum pump for R410A exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum pump or the unit. ACAUTION It is highly recommended that you do not open/close the stop valves when the outdoor temperature is below —5°F (-21 °C) as this may result in refrigerant leakage. • When piping work is complete, it is necessary to perform a pressure test and evacuate system with a vacuum pump. • If using additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant. • Use a hexagonal wrench (3/16 inch (4mm)) to operate the stop valve rods. • All refrigerant pipe joints should be tightened with a torque wrench to the specified tightening torque. Valve caps Low-pressure valve Compound pressure gauge Pressure meter J C ; f High-pressure 1 valve Gauge manifold Charging hoses Vacuum pump 1) Pressurize the liquid pipe and gas pipe from the service ports of each stop valve to 550psi (3.8MPa) (do not pressurize more than 550psi (3.8MPa)) for 1 hour minimum, 24 hours recommended. If there is a pressure drop, check for leaks, make repairs and perform the pressure test again. 2) Connect the gauge manifold's charging hose to the gas stop valve's service port. 3) Fully open the low-pressure valve (Lo) on the gauge manifold and fully close the high-pressure valve (Hi). (High-pressure valve will require no further operation.) 4) Evacuate system using vacuum pump to below 500 microns for 1 hour minimum. 5) Close the low-pressure valve (Lo) on the gauge manifold and stop vacuum pump. (Maintain this condition for 4-5 minutes to make sure that the compound pressure gauge pointer does not swing back.)" 6) Remove the valve caps from the liquid stop value and gas stop valve. 7) To open the liquid stop valve, turn the rod of the valve 90° counter -clockwise using a hexagonal wrench. Close it after 5 seconds, and check for gas leakage. Using soapy water, check for gas leakage from the indoor unit's flare and outdoor unit's flare and valve rods. After the check is complete, wipe all soapy water off. 8) Disconnect the charging hoses from the service port for the gas stop valve, then fully open the liquid and gas stop valves. (Do not attempt to turn the valve rods further than they can go.) 9) Tighten the valve caps and service port caps for the liquid and gas stop valves with a torque wrench to the specified torques. Refer to "4. Refrigerant piping" on page 9 for details. If the compound pressure gauge pointer swings back, the refrigerant may have water content or there may be a loose pipe joint. Check all pipe joints and retighten nuts as needed, then repeat steps 3) through 5). ■ English 10 Outdoor Unit Installation 6. Refilling refrigerant Check the type of refrigerant to be used on the machine nameplate. Precautions when adding R410A Fill from the liquid pipe in liquid form. R410A is a mixed refrigerant, so adding it in gas form may cause the refrigerant composition to change, preventing normal operation. 1) Before filling, check whether the cylinder has a siphon attached or not. (It should have something like "liquid filling siphon attached" displayed on it.) Filling a cylinder with an attached siphon Stand the cylinder upright when filling. There is a siphon pipe inside, so the cylinder need not be upside-down to fill with liquid. Filling other cylinders Turn the cylinder upside-down when filling. • Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering. 7. Charging with refrigerant rAI ITIlt-M `.---- - --- - Even though the stop valve is fully closed, the refrigerant may slowly leak out; do not leave the flare nut removed for a long period of time. • If the total length of piping for all rooms exceeds the figure listed below, additionally charge with 0.21 oz/ft (20g/m) of refrigerant (R410A) for each additional piping length.

The wiring error check can be conveniently used for underground wiring and other wiring that cannot be directly checked. However, if the outside air temperature Is . - , the wiring error check function will not operate. 1. Wiring error check This product is capable of automatic correction of wiring errors. Press the wiring error check switch on the outdoor unit service PC -board. However, the wiring error check switch will not function for 3 minutes after the safety breaker is turned on. About 15-25 minutes after the switch is pressed, the errors in the connection wiring will be corrected. The service monitor LEDs indicate whether or not correction is possible, as shown in the table below. For details on how to read the LED display, refer to the collective indications label on the reverse side of the right side plate or the service manual. Wiring error- - check switch If self -correction is not possible, check the indoor unit wiring and piping in the usual (SW3) manner.

This is normal. 3) Follow the product diagnosis procedures. (Details of product error diagnosis are listed on the reverse side of the right side plate.) 17 0 English 2. Trial operation and testing • During the trial operation, first check the operation of each unit individually. After this, check the simultaneous operation of all indoor units. Check both COOL and HEAT operations. 2-1. Measure the supply voltage and make sure that it is within the specified range. 2-2. In COOL operation, select the lowest programmable temperature; in HEAT operation, select the highest programmable temperature. • When operating the air conditioner in COOL operation in winter, or HEAT operation in summer, activate trial operation mode by following the instructions in the installation manual for the indoor unit. 2-3. Carry out the trial operation following the instructions in the operation manual to ensure that all functions and parts, such as the movement of the flap, are working properly. • To protect the air conditioner, restart operation is disabled for 3 minutes after the system has been turned off. • When trial operation is conducted in HEAT operation directly after the circuit breaker is turned on, in some cases no air will be output for about 3 to 20 minutes in order to protect the air conditioner. During COOL operation, frost may form on the gas stop valve or other parts. This is normal. 2-4. After running the unit for about 20 minutes, measure the temperatures at the indoor unit inlet and outlet. If the measurements are above the values shown in the table below, then they are normal. Temperature difference between inlet and outlet COOL operation I HEAT operation About 14°F (8°C) I About 36°F (20oC) (When running in one room) 2-5. After trial operation is complete, set the temperature to a normal level (78T to 820F (26°C to 28°C) in COOL operation, 68OF to 750F (20°C to 24°C) in HEAT operation). • The air conditioner draws a small amount of power in its standby mode. If the system is not to be used for some time after installation, shut off the circuit breaker to eliminate unnecessary power consumption. 3.
