1. Safety Precautions
Read the following “SAFETY PRECAUTIONS” carefully before perform any servicing.
Electrical work must be installed or serviced by a licensed electrician. Be sure to use the correct rating of the power plug and
main circuit for the model 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 or servicing due to ignoring of the instruction will cause harm or damage,
and the seriousness is classified by the following indications.
and the seriousness is classified by the following indications.
WARNING
This indication shows the possibility of causing death or serious injury.
CAUTION
This indication shows the possibility of causing injury or damage to properties.
The items to be followed are classified by the symbols:
This symbol denotes item that is PROHIBITED from doing.
Carry out test run to confirm that no abnormality occurs after the servicing. 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.
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.
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.

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.
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 0.8 mm. Never use copper pipes thinner than 0.8 mm.
It is desirable that the amount of residual oil less than 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 weight of the set. If the strength is not enough or installation is not properly
done, the set will drop and cause injury.
done, the set will drop and cause injury.
14.
For electrical work, follow the local national wiring standard, regulation and this installation instruction. An independent circuit and single
outlet must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.

15.
Do not use joint cable for indoor / outdoor connection cable. Use the specified indoor/outdoor connection cable, refer to instruction
CONNECT THE CABLE TO THE INDOOR 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 fi re at the connection.
