IMPORTANT
1.
This product has been designed and manufactured to meet
ENERGY STAR®
criteria for energy efficiency when matched with appropriate coil components. However, proper refrigerant
charge and proper air flow are critical to achieve rated capacity and efficiency. Installation of this product should follow the manufacturer’s refrigerant charging and air flow instructions.
Failure to con
°
rm proper charge and air
°
ow may reduce energy ef
°
ciency and shorten equipment life.
2.
This model is equipped with Room Freeze Protection (RFP) feature. Room Freeze Protection function (RFP) is used in spaces that are unoccupied during the winter, for the purpose
of protecting any equipment or appliances which may be destroyed as a result of freezing temperature. When the RFP is selected, the unit will operate the fan at high speed for proper
room temperature monitoring. When the sensor detects that the room temperature has dropped below 46°F (8°C), the compressor/heat pump operation begins. When the room
temperature reaches 50°F (10°C), the unit shuts off, then will repeat continuously if the temperature drops below 46°F (8°C) again.
The Room Freeze Protection function (RFP) cannot be used unless the unit is energized and set into the RFP mode. In the advent of a power failure this mode will not function. During
the RFP mode, POWERFUL OPERATION, QUIET OPERATION AND FAN SPEED selection are all disabled. Please consult with your HVAC installer or professional for more details.

WARNING
Do not install outdoor unit near handrail of veranda. When installing air-conditioner unit on veranda of a high rise building, child may climb up to outdoor unit and cross over
the handrail causing an accident.
Do not use unspecified cord, modified cord, joint cord or extension cord for power supply cord. Do not share the single outlet with other electrical appliances. Poor contact,
poor insulation or over current will cause electrical shock or fire.
Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.
Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.
Do not sit or step on the unit, you may fall down accidentally.
Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.
When installing or relocating air conditioner, do not let any substance other than the specified refrigerant, eg. air etc mix into refrigeration cycle (piping). Mixing of air etc will
cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc.
•
For R32/R410A model, use piping, flare nut and tools which is specified for R32/R410A refrigerant. Using of existing (R22) piping, flare nut and tools may cause abnormally
high pressure in the refrigerant cycle (piping), and possibly result in explosion and injury.
For R32 and R410A, the same flare nut on the outdoor unit side and pipe can be used.
•
Since the working pressure for R32/R410A is higher than that of refrigerant R22 model, replacing conventional piping and fl
are nuts on the outdoor unit side are recommended.
•
If reuse piping is unavoidable, refer to instruction “IN CASE OF REUSING EXISTING REFRIGERANT PIPING”
•
Thickness for copper pipes used with R32/R410A must be more than
1
/
32
" (0.8 mm). Never use copper pipes thinner than
1
/
32
" (0.8 mm).
•
It is desirable that the amount of residual oil is less than 0.00004 oz/ft (40 mg/10 m).
Engage authorized dealer or specialist for installation. If installation done by the user is incorrect, it will cause water leakage, electrical shock or fire.
Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fire.
Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water leakage, fire or electrical shock.

and connect tightly for indoor/outdoor connection. Clamp the cable so that no external force will have impact on the terminal. If connection or fixing is
not perfect, it will cause heat-up or fire at the connection.
Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will cause fire or electrical shock.
This equipment must installed with an Earth Leakage Circuit Breaker (ELCB) or Ground Fault Current Interrupter (GFCI) or Appliance Leakage Current Interrupter (ALCI) that
has been certified by an NRTL Certified Testing Agency and that is suitable for the voltages and amperages involved. Otherwise, if may cause electrical shock and fire in case
of equipment breakdown.
During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fixing refrigeration piping and valves at opened
condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
During pump down operation, stop the compressor before removing the refrigeration piping. Removal of refrigeration piping while compressor is operating and valves are
opened will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare may break and cause refrigerant gas leakage.
After completion of installation, confirm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant comes into contact with fire.
Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant comes into contact with fire.
This equipment must be properly earthed. Earth line must not be connected to gas pipe, water pipe, earth of lightning rod and telephone. Otherwise, it may cause electrical
shock in case of equipment breakdown or insulation breakdown.
CAUTION
Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may cause fire.

WHEN INSTALLING AN AIR CONDITIONER, BE SURE TO EVACUATE THE AIR INSIDE THE INDOOR
UNIT AND PIPES in the following procedure.
1. Connect a charging hose with a push pin to the Low side of a charging set and the service port of the
3-way valve.
2. Connect the micron gauge between vacuum pump and service port of outdoor units.
3. Turn on the power switch of the vacuum pump and make sure that connect digital micron gauge and
to pull down to a value of 500 microns.
4. To make sure micron gauge a value 500 microns and close the low side valve of the charging set and
turn off the vacuum pump.
5. Disconnect the vacuum pump house from the service port of the 3-way valve.
6. Tighten the service port caps of the 3-way valv
e at a torque of 13.3 Ibf•ft (18 N•m) with a torque wrench.
7. Remove the valve caps of both of the 2-way valve and 3-way valve. Position both of the valves to
“Open” using a hexagonal wrench (5/32" (4 mm)).
8. Mount valve caps onto the 2-way valve and the 3-way valve.
•
Be sure to check for gas leakage.
•
If micron gauge value does not descend 500 microns, take the following measures:
- If the leak stops when the piping connections are tightened further, continue working from step
3
.
- If the leak does not stop when the connections are retightened, repair location of leak.
- Do not release refrigerant during piping work for installation and reinstallation.
- Be careful with the liquid refrigerant, it may cause frostbite.
