1. Safety Precautions
Read the following “SAFETY PRECAUTIONS” carefully before installation.
Electrical work must be installed by a licensed electrician. Be sure to use the correct rating of the power plug and main circuit
for the model to be installed.
The caution items stated here must be followed because these important contents are related to safety. The meaning of each
indication used is as below. Incorrect installation due to ignoring of the instruction will cause harm or damage, and the
seriousness is classified by the following indications.
WARNING
CAUTION
The items to be followed are classified by the symbols:
Carry out test running to confirm that no abnormality occurs after the installation. Then, explain to user the operation, care
and maintenance as stated in instructions. Please remind the customer to keep the operating instructions for future reference.
This indication shows the possibility of causing death or serious injury.
This indication shows the possibility of causing injury or damage to properties only.
Symbol with white background denotes item that is PROHIBITED.
Symbol with dark background denotes item that must be carried out.
WARNING
Do not install outdoor unit near handrail of veranda. When installing air-conditioner unit on veranda of a high rise building, child
1.
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
2.
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.
When installing or relocating air conditioner, do not let any substance other than the specified refrigerant, eg. air etc mix into
7.
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.
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.
9.
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).
Engage authorized dealer or specialist for installation. If installation done by the user is incorrect, it will cause water leakage, electrical
10.
shock or fire.
11. 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
12.
electrical shock.
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
13.
done, the set will drop and cause injury.
For installation work, follow all electrical, building, plumbing, local codes, regulations and these installation instructions. If electrical circuit
14.
capacity is not enough or a defect is found in electrical work, it will cause electrical shock or fire.
Do not use spliced wires for indoor/outdoor connection cable. Use the specified indoor/outdoor connection cable, refer to instruction
15.
CONNECT THE CABLE TO THE INDOOR/OUTDOOR UNIT 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
16.
cause fire or electrical shock.
This equipment must installed with an Earth Leakage Circuit Breaker (ELCB) or Ground Fault Current Interrupter (GFCI) or Appliance
17.
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.
3
During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fixing
18.
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
19.
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
20.
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
21.
contact with fire.
22. 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.
23.
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
1.
of the unit, it may cause fire.
Do not release refrigerant during piping work for installation, re-installation and during repairing a refrigeration parts. Take care
2.
of the liquid refrigerant, it may cause frostbite.
3. Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.
4.
Do not touch the sharp aluminium fin, sharp parts may cause injury.
Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the
5.
furniture.
6. Select an installation location which is easy for maintenance.
Power supply connection to the room air conditioner.
Power supply cord shall be UL listed or CSA approved 3 conductor with minimum AWG14 (E9SD3UAW, E12SD3UAW) and AWG12
(E18SD3UAW) wires.
7.
Power supply point should be in an easily accessible place for power disconnection in case of emergency.
In some countries, permanent connection of this air conditioner to the power supply is prohibited.
Fix power supply connection to a circuit breaker for permanent connection.
Use NRTL approved fuse or circuit breaker (rating refers to name plate) for permanent connection.
Installation work.
8.
It may take two people to carry out the installation work.
