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 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.
harm or damage, and the seriousness is classified by the following indications.
Please leave this installation manual with the unit after installation.
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 only.
The items to be followed are classified by the symbols:
Symbol with white background denotes item that is PROHIBITED from doing.
Symbol with dark background denotes item that must be carried out.
Carry out test run 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.

11.
Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock or
fire.
fire.
12.
This is a R410A model, when connecting the piping, do not use any existing (R22) pipes and flare nuts. Using such same may
cause abnormally high pressure in the refrigeration cycle (piping), and possibly result in explosion and injury. Use only R410A
refrigerant.

refrigerant.
Thickness or copper pipes used with R410A must be 0.8 mm or more. Never use copper pipes thinner than 0.8 mm.
It is desirable that the amount of residual oil is less than 40mg/10m.
13.
When install or relocate Indoor Unit, do not let any substance other than the specified refrigerant, e.g. air etc. mix into refrigerant cycle
(piping).
Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
(piping).
Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
14. Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fire.
15.
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.
properly done, the set will drop and cause injury.
16.
This equipment is strongly recommended to be installed with Residual Current Device (RCD) on-site according to the respective
national wiring rules or country-specific safety measures in terms of residual current.

WARNING
17.
During installation, install the refrigerant piping properly before run 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.
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.
18.
During pump down operation, stop the compressor before remove the refrigeration piping. Removal of refrigerant 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.
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.
19.
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.
