Do not insert your fi ngers or other objects into the unit, high speed rotating fan may cause injury.
Do not sit or step on the unit, you may fall down accidentally.
Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.
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.
Do not use pipe wrench to install refrigerant piping. It might deform the piping and cause the unit to malfunction.
Do not purchase unauthorized electrical parts for installation, service, maintenance and etc.. They might cause electrical shock or fi re.
Do not modify the wiring of outdoor unit for installation of other components (i.e. heater, etc). Overloaded wiring or wire connection points may
cause electrical shock or fi re.
Do not pierce or burn as the appliance is pressurized. Do not expose the appliance to heat, fl ame, sparks, or other sources of ignition.
Else, it may explode and cause injury or death.
Do not add or replace refrigerant other than specifi ed type. It may cause product damage, burst and injury etc.
For electrical work, follow local 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 fi re.
Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock or fi re.
•
For R32 model, use piping, fl are nut and tools which is specifi ed for R32 refrigerant. Using of existing (R22) piping, fl are 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 R32 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 is less than 40 mg/10 m.
For refrigeration system work, 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.
Wire routing must be properly arranged so that control board cover is fi xed properly. If control board cover is not fi xed perfectly, it will cause fi re
or electrical shock.
During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fi xing refrigeration
piping and valves at opened position 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.
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.
Be aware that refrigerants may not contain an odour.
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.
Incorrect installation, service or repair of this outdoor unit may increase the risk of rupture and this may result in loss damage or injury and/or property.
Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or fi re.
