This appliance is filled with R32. • The precautions described herein are classified as WARNING and CAUTION. They both contain important information regarding safety. Be sure to observe all precautions without fail. • Meaning of WARNING and CAUTION notices WARNING.....Failure to follow these instructions properly may result in personal injury or loss of life. CAUTION......Failure to observe these instructions properly may result in property damage or personal injury, which may be serious depending on the circumstances. • The safety marks shown in this manual have the following meanings: Be sure to follow the instructions. Be sure to establish an earth connection. Never attempt. • After completing installation, conduct a trial operation to check for faults and explain to the customer how to operate the air conditioner and take care of it with the aid of the operation manual. • The English text is the original instruction. Other languages are translations of the original instructions. WARNING • Ask your dealer or qualified personnel to carry out installation work. Do not attempt to install the air conditioner yourself. Improper installation may result in water leakage, electric shocks or fire. • Install the air conditioner in accordance with the instructions in this installation manual. Improper installation may result in 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 the unit falling, water leakage, electric shocks or fire. • Install the air conditioner on a foundation strong enough to withstand the weight of the unit. A foundation of insufficient strength may result in the equipment falling and causing injury. • Electrical work must be performed in accordance with relevant local and national regulations and with instructions in this installation manual. Be sure to use a dedicated power supply circuit only. Insufficiency of power circuit capacity and improper workmanship may result in electric shocks or fire. • Use a cable of suitable length. Do not use tapped wires or an extension lead, as this may cause overheating, electric shocks or fire. • Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal connections or wires. Improper connections or securing of wires may result in abnormal heat build-up or fire. • When wiring the power supply and connecting the wiring between the indoor and outdoor units, position the wires so that the control box cover can be securely fastened. Improper positioning of the control box cover may result in electric shocks, fire or over heating terminals. • If refrigerant gas leaks during installation, ventilate the area immediately. Toxic gas may be produced if the refrigerant comes into contact with fire. • After completing installation, check for refrigerant gas leakage. Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of fire, such as a fan heater, stove or cooker. • When installing or relocating the air conditioner, be sure to bleed the refrigerant circuit to ensure it is free of air, and use only the specified refrigerant (R32). The presence of air or other foreign matter in the refrigerant circuit causes abnormal pressure rise, which may result in equipment damage and even injury. • During installation, attach the refrigerant piping securely before running the compressor. If the refrigerant pipes are not attached and the stop valve is open when the compressor is run, air will be sucked in, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury. • During pump-down, stop the compressor before removing the refrigerant piping. If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury. • Be sure to earth the air conditioner. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks. • Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in electric shocks or fire. • If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard. English 1 3PEN386697-3G.book Page 2 Monday, April 24, 2017 11:02 AM Safety Precautions CAUTION • Do not install the air conditioner at any place where there is a danger of flammable gas leakage. In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire to break out. • While following the instructions in this installation manual, install drain piping to ensure proper drainage and insulate piping to prevent condensation. Improper drain piping may result in indoor water leakage and property damage. • Tighten the flare nut according to the specified method such as with a torque wrench. If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage. • Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals. Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the unit clean. • The temperature of refrigerant circuit will be high, please keep the inter-unit wire away from copper pipes that are not thermally insulated. • This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or for commercial and household use by lay persons. • Sound pressure level is less than 70 dB(A). • Only use accessories, optional equipment and spare parts made or approved by DAIKIN.

The pipe end must be evenly flared in a perfect circle. Make sure that the flare nut is fitted. WARNING • • • • • • • 4. Do not use mineral oil on flared part. Prevent mineral oil from getting into the system as this would reduce the lifetime of the units. Never use piping which has been used for previous installations. Only use parts which are delivered with the unit. Never install a dryer to this R32 unit in order to guarantee its lifetime. The drying material may dissolve and damage the system. Incomplete flaring may cause refrigerant gas leakage. Protect or enclose refrigerant tubing to avoid mechanical damage. Refrigerant piping work CAUTION • • • • Use the flare nut fixed to the main unit. (To prevent cracking of the flare nut by aged deterioration.) To prevent gas leakage, apply refrigeration oil only to the inner surface of the flare. (Use refrigeration oil for R410A or R32.) Use torque wrenches when tightening the flare nuts to prevent damage to the flare nuts and gas leakage. After the piping work is finished (after checking for gas leaks), open the stop valves or the compressor might break down. • Align the centres of both flares and tighten the flare nuts 3 or 4 turns by hand.

Evacuating the air with a vacuum pump and checking gas leakage WARNING • • • • Do not mix any substance other than the specified refrigerant (R32) into the refrigeration cycle. When refrigerant gas leaks occur, ventilate the room as soon and as much as possible. R32, as well as other refrigerants, should always be recovered and never be released directly into the environment. Use a vacuum pump for R32 or R410A exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum pump or the unit. • Use tools for R32 or R410A (such as the gauge manifold, charging hose, or vacuum pump adapter). • When piping work is completed, it is necessary to evacuate the air and check for gas leakage. • If using additional refrigerant, perform air evacuating from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional refrigerant. • Use a hexagonal wrench (4mm) to operate the stop valve rod. • All refrigerant pipe joints should be tightened with a torque wrench at the specified tightening torque. Compound Pressure pressure gauge metre Gauge manifold Low-pressure valve Highpressure valve Valve caps Liquid stop valve Charging hoses Vacuum pump Service port Gas stop valve 1) Connect projection side of charging hose (which comes from gauge manifold) to gas stop valve’s service port. 2) Fully open gauge manifold’s low-pressure valve (Lo) and completely close its high-pressure valve (Hi). (High-pressure valve subsequently requires no operation.) 3) Do vacuum pumping and make sure that the compound pressure gauge reads –0.1MPa (–76cmHg).*1 4) Close gauge manifold’s low-pressure valve (Lo) and stop vacuum pump. (Keep this state for a few minutes to make sure that the compound pressure gauge pointer does not swing back.)*2 5) Remove caps from liquid stop valve and gas stop valve. 6) Turn the liquid stop valve’s rod 90 degrees counterclockwise with a hexagonal wrench to open valve. Close it after 5 seconds, and check for gas leakage. Using soapy water, check for gas leakage from indoor unit’s flare and outdoor unit’s flare and valve rods. After the check is complete, wipe all soapy water off. 7) Disconnect charging hose from gas stop valve’s service port, then fully open liquid and gas stop valves. (Do not attempt to turn valve rod beyond its stop.) 8) Tighten valve caps and service port caps for the liquid and gas stop valves with a torque wrench at the specified torques.

Frequently asked questions
The system should be used in an outdoor temperature range of -10~46°C for cooling and -15~24°C for heating. The indoor temperature range for cooling is 18~32°C and for heating it's 10~30°C. The maximum indoor humidity should be less than 80%.
Choose a location that is solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified. Ensure there is enough space for air passage and no obstructions around the air inlet and outlet. Avoid places near bedrooms, and install the unit at least 3m away from television and radio sets to prevent interference with images and sounds.
If the total length of refrigerant piping exceeds 10m, add refrigerant. Subtract 10m from the overall length and calculate the amount of additional refrigerant needed based on a 20g/m requirement.
Pump down operation is used to protect the environment when relocating or disposing of the unit. It involves removing the refrigerant from the system and recovering it into a separate cylinder.
