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: QDANGER ......••••• Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Q WARNING ......••• Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. Q 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. QNOTE ............•••• 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. Qt, 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. • It is recommended to install a ground fault circuit interrupter if one is not already available. This helps prevent electric shock or fire. • 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. Q 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 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 earths 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. This unit is for indoor use. • 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. Qt, NOTE • Install the power supply and inter -unit wires for the indoor and outdoor units at least 3.5ft away from televisions or radios to prevent image interference or noise. Depending on the radio waves, a distance of 3.5ft 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 478 psi, the wall thickness of field - installed pipes should be selected in accordance with the relevant local, state, and national regulations. s N C w ■ English 2 Accessories �A Mounting plate 1 © Mounting plate fixing screw 7 © Titanium apatite photocatalytic *12 2 3/16" x 1" (M4 x 25mm) air -purifying filter QD Wireless remote controller 1 Remote controller holder 1 O Fixing screw for remote controller 2 holder 1/8" x 13/16" (M3 x 20mm) QG Dry battery AAA.

Start -Up UNIT OPERATION AND SAFETY HAZARD Failure to follow this caution may result in personal injury, equipment damage or improper operation. • Do not overcharge system with refrigerant. • Do not operate unit in a vacuum or at negative pressure. • Compressor dome temperatures may be hot. PERSONAL INJURY HAZARD Failure to follow this caution may result in personal injury. Wear safety glasses, protective clothing, and gloves when handling refrigerant and observe the following: • Front seating service valves are equipped with Schrader valves. Follow these steps to properly start up system: 1. After system is evacuated, fully open liquid and vapor ser- vice valves. 2. Unit is shipped with valve stem(s) front seated (closed) and caps installed. Replace stem caps after system is opened to refrigerant flow. Replace caps finger -tight and tighten with wrench an additional 1/12 turn. 3. Close electrical disconnects to energize system. 4. Set room thermostat at desired temperature. Be sure set point is below indoor ambient temperature. 5. Set room thermostat to COOL and fan control to ON or AUTO mode, as desired. Operate unit for 15 minutes. Check system refrigerant charge. Sequence of Operation Turn on power to indoor and outdoor units. Transformer is energized. On a call for cooling, thermostat makes circuits R-Y and R-G. Circuit R-Y energizes contactor, starting outdoor fan motor and compressor circuit. R-G energizes indoor unit blower relay, starting indoor blower motor on high speed. When thermostat is satisfied, its contacts open, de -energizing contactor and blower relay. Compressor and motors stop. If indoor unit is equipped with a time -delay relay circuit, the indoor blower will run an additional 90 seconds to increase system efficiency. Check Charge Factory charge amount and desired subcooling are shown on unit rating plate. Charging method is shown on information plate inside unit. To properly check or adjust charge, conditions must be favorable for subcooling charging. Favorable conditions exist when the outdoor temperature is between 70°F and 100°F (21.11°C and 37.78°C), and the indoor temperature is between 70°F and 80°F (21.11°C and 26.67°C). Follow the procedure below: Adjust charge by adding or removing 0.6 oz/ft of 3/8 liquid line above or below 15 ft. (4.57 m) respectively. NOTE: For 15 ft. (4.57 m) line set charge, refer to Table 5. Some unit tonnages may require additional charge depending on size. Find model tonnage size in table, reference factory charge versus required charge to determine if additional charge is required. Additional charge will be needed for line sets longer than 15 ft. (4.57 m). For standard refrigerant line lengths (80 ft/24.38 m or less), allow system to operate in cooling mode at least 15 minutes. If conditions are favorable, check system charge by subcooling method. If any adjustment is necessary, adjust charge slowly and allow system to operate for 15 minutes to stabilize before declaring a properly charged system. If the indoor temperature is above 80°F (26.67°C), and the outdoor temperature is in the favorable range, adjust system charge by weight based on line length and allow the indoor temperature to drop to 80°F (26.67°C) before attempting to check system charge by subcooling method as described above. If the indoor temperature is below 70°F (21.11°C), or the outdoor temperature is not in the favorable range, adjust charge for line set length above or below 15 ft. (4.57 m) only. Charge level should then be appropriate for the system to achieve rated capacity. The charge level could then be checked at another time when the both indoor and outdoor temperatures are in a more favorable range. NOTE: If line length is beyond 80 ft (24.38 m) or greater than 35 ft (10.7 m) vertical separation, See Long Line Guideline for special charging requirements.

Ensure that all wiring is routed away from tubing and sheet metal edges to prevent rub -through or wire pinching. 2. Ensure that all wiring and tubing is secure in unit before adding panels and covers. Securely fasten all panels and covers. 3. Tighten service valve stem caps to 1/12-turn past finger tight. 4. Leave Owner's Manual with owner. Explain system opera- tion and periodic maintenance requirements outlined in manual. 5. Fill out Dealer Installation Checklist and place in customer file. CARE AND MAINTENANCE For continuing high performance and to minimize possible equipment failure, periodic maintenance must be performed on this equipment. Frequency of maintenance may vary depending upon geographic areas, such as coastal applications. See Owner's Manual for more information.
