Outdoor Unit
• Do not use any refrigerant different from the one specified for complement or replacement.
Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which
may result in a failure or explosion of the product or an injury to your body.
• Installation work must be requested from the supplying retail dealership or professional
vendors. Self-installation may cause water leakage, electrical shock, or fire as a result of
improper installation.
• Specified tools and pipe parts for model R410A are required, and installation work must
be done in accordance with the manual. HFC type refrigerant R410A has 1.6 times more
pressure than that of conventional refrigerant (R22). Use the specified pipe parts, and
ensure correct installation, otherwise damage and/or injury may be caused. At the same
time, water leakage, electrical shock, and fire may occur.
• Be sure to install the unit in a place which can sufficiently bear its weight. If the load bearing
of the unit is not enough, or installation of the unit is improper, the unit may fall and result in
injury.
• Electrical work must be performed by a qualified electrical engineer in accordance with
the code governing such installation work, internal wiring regulations, and the manual. A
dedicated circuit and the rated voltage must be used. Insufficient power supply or improper
installation may cause electrical shock or fire.
• Use a cabtyre cable to connect wires in the indoor/outdoor units. Midway connection,
stranded wire, and single-wire connections are not allowed. Improper connection or fixing
may cause a fire.
• Wiring between the indoor unit and outdoor units must be well shaped so that the cover can
be firmly placed. Improper cover installation may cause increased heat, fire, or electrical
shock at the terminal area.
• Be sure to use only approved accessories or the specified parts. Failure to do so may
cause the unit to fall, water leakage, fire or electrical 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 else
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 or
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 the 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 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.
• Do not modify the power cable, connect the cable midway, or use a multiple outlet
extension cable. Doing so may cause contact failure, insulation failure, or excess current,
resulting in fire or electrical shock.
