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.
This equipment is strongly recommended to be installed with Residual Current Device (RCD) on-site according to the respective national wiring
rules or country–specifi c safety measures in terms of residual current.
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.
The unit is only for use in closed water system. Utilization in an open water circuit may lead to excessive corrosion of water piping and risk of
incubating bacteria colonies, particularly Legionella, in water.
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 Indoor 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 Indoor 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.
Do not install this appliance in a laundry room or other high humidity location. This condition will cause rust and damage to the unit.
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 apply excessive force to water pipes that may damage the pipes. If water leakage occurs, it will cause fl ooding and damage to other
properties.
Select an installation location which is easy for maintenance.
Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the furniture.
Power supply connection to Indoor Unit.
•
Power supply point should be in easily accessible place for power disconnection in case of emergency.
•
Must follow local national wiring standard, regulation and this installation instruction.
•
Strongly recommended to make permanent connection to a circuit breaker.
- Power Supply 1: Use approved 30A 2-poles circuit breaker with a minimum contact gap of 3.0mm.
- Power Supply 2: Use approved 30A 2-poles circuit breaker with a minimum contact gap of 3.0mm.
Ensure the correct polarity is maintained throughout all wiring. Otherwise, it will cause electrical shock or fi re.
After installation, check the water leakage condition in connection area during test run. If leakage occurs, it will cause damage to other properties.
Installation work.
It may need two or more people to carry out the installation work. The weight of Indoor Unit might cause injury if carried by one person.
