This is a R410A model, when connecting the piping, do not use any existing (R22) pipes and fl are 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.
•
Thickness or copper pipes used with R410A must be 0.8mm or more. Never use copper pipes thinner than 0.8mm.
•
It is desirable that the amount of residual oil is less than 40mg/10m.
When install or relocate outdoor unit, do not let any substance other than the specifi ed 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.
Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock or fi re.
Install at a strong and fi rm 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.
Do not use joint cable for outdoor connection cable. Use specifi ed outdoor connection cable, refer to instruction 5 CONNECT THE CABLE
TO THE OUTDOOR UNIT and connect tightly for outdoor connection. Clamp the cable so that no external force will be acted on the terminal. If
connection or fi xing is not perfect, it will cause heat up or fi re at the connection.
During installation, install the refrigerant piping properly before run the compressor. Operation of compressor without fi xing 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 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 refrigerant cycle and result in explosion, injury etc.
Tighten the fl are nut with torque wrench according to specifi ed method. If the fl are nut is over tightened, after a long period, the fl are may break
and cause refrigerant gas leakage.
After completion of installation, confi rm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant contacts with fi re.
Ventilate the room if there is refrigerant gas leakage during operation. Extinguish all fi re sources if present. It may cause toxic gas when the
refrigerant contacts with fi re.
Only use the supplied or specifi ed installation parts, else, it may cause unit vibrate loose, water leakage, electrical shock or fi re.
If there is any doubt about the installation procedure or operation, always contact the authorized dealer for advice and information.
Select a location where in case of water leakage, the leakage will not cause damage to other properties.
When installing electrical equipment at wooden building of metal lath or wire lath, in accordance with electrical facility standard, no electrical
contact between equipment and building is allowed. Insulator must be installed in between.
Any work carried out on the outdoor unit after removing any panels which is secured by screws, must be carried out under the supervision of
authorized dealer and licensed installation contractor.
This unit must be properly earthed. The electrical earth must not be connected to a gas pipe, water pipe, the earth of lightening rod or a telephone.
Otherwise there is a danger of electrical shock in the event of an insulation breakdown or electrical earth fault in the outdoor unit.
Do not install the outdoor unit at place where leakage of fl ammable gas may occur. In case gas leaks and accumulates at surrounding of the
unit, it may cause fi re.
Do not release refrigerant during piping work for installation, re-installation and during repairing a refrigeration parts. Take care of the liquid
refrigerant, it may cause frostbite.
Make sure the insulation of power supply cord does not contact hot part (i.e. refrigerant piping) to prevent from insulation failure (melt).
Do not touch the sharp aluminium fi n, sharp parts may cause injury.
Select an installation location which is easy for maintenance.
Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or fi re.
Installation work.
It may need two or more people to carry out the installation work. The weight of outdoor unit might cause injury if carried by one person.
