WARNING
1.
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.
2.
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.
3.
Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.
4.
Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.
5.
Do not sit or step on the unit, you may fall down accidentally.
6.
Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.
7.
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.
8.
Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc.
9.
For R410A model, use piping, flare nut and tools which is specified for 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.
Thickness for copper pipes used with 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 less than 0.0008 oz/ft (40 mg/10 m).
10.
Engage authorized dealer or specialist for installation. If installation done by the user is incorrect, it will cause water leakage, electrical
shock or fire.
11. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fire.
12.
Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water leakage, fire or
electrical shock.
13.
Install at a strong and firm location which is able to withstand the set’s weight. If the strength is not enough or installation is not properly
done, the set will drop and cause injury.
14.
For installation work, follow all electrical, building, plumbing, local codes, regulations and these installation instructions. If electrical circuit
capacity is not enough or a defect is found in electrical work, it will cause electrical shock or fire.
15.
Do not use spliced wires for indoor/outdoor connection cable. Use the specified indoor/outdoor connection cable, refer to instruction
INDOOR/OUTDOOR UNIT ELECTRICAL WIRING
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.
16.
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.
17.
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.
