WARNING
• Wiring between the indoor unit and outdoor units must be well shaped so that the cover
can be fir ly placed. Improper cover installation may cause increased heat, fire, o
electrical shock at the terminal area.
• Be sure to use only approved accessories or the specified parts. Failure to do so ma
cause the unit to fall, water leakage, fire or el ctrical shock.
• After the installation work, ensure that there is no leakage of refrigerant gas. If the
refrigerant gas leaks out of the pipe into the room and is heated by fire or something els
from a fan heater, stove or gas range, it causes generation of poisonous gas.
• Make sure the equipment is properly earthed. Do not connect the earth wire to a gas pipe,
water pipe, lightning conductor, or telephone earth wire. Improper earth work may be the
cause of electrical shock.
• Do not install the unit where flammable gas may leak. If there is any gas leakage o
accumulation around the unit, it can cause a fire
• Do not select a location for installation where there may be excessive water or humidity,
such as a bathroom. Deterioration of insulation may cause electrical shock or fire
• Installation work must be performed following the instructions in this installation manual.
Improper installation may cause water leakage, electrical shock or fire. Check th
following items before operating the unit.
- Be sure that the pipe connection is well placed and there are no leaks.
- Check that the service valve is open. If the service valve is closed, it may cause
overpressure and result in compressor damage. At the same time, if there is a leak in
the connection part, it may cause air suction and overpressure, resulting in burst or
injury.
• The installation of pipe work shall be kept to a minimum.
• The following must be certainly done during pump down.
• Do not incorporate air into the refrigeration cycle.
• Close the 2 service valves. Stop the compressor and remove the refrigerant pipe.
If the refrigerant pipe is removed when the compressor is operating and service valves are
opened, the refrigerant cycle will inhale unwanted matter such as air and the pressure in
the cycle becomes abnormally elevated. It may cause a burst or injury.
