Installation Procedure
WARNING
• Should adopt bar type louver. Don’t use a type of rain
resistance louver.
[Rain resistance louver]
[Bar type louver]
• Louver specifications.
– Angle criteria : less than 20°
– Opening ratio criteria : greater than 80%
WARNING
• After installing the outdoor unit, apply rust inhibitor on
the internal pipes and heat exchanger.
– Airborne corrosive gas such as sulfur compounds,
hydrogen sulfide, and ammonia, or salty dust may
cause pipe corrosion. This corrosion may result in
refrigerant leakage.
– Inspect the outdoor unit at least once a year and
re-apply the rust inhibitor where it is damaged or
worn out.
• When applying rust inhibitor, be sure to follow the
instructions below:
– Turn off the power before spraying the rust
inhibitor.
– Wear protective goggles and a mask in advance.
– Clean the dusty surface with clean fabric or paper
before spraying the inhibitor.
– Make sure that wind is blowing from behind the
worker.
– Do not spray on the PCB panel and electric parts.
CAUTION
• Install the indoor unit away from any interference,
such as radios, computers, and stereo devices, and
also select the place where the electrical wiring work
is possible.
– Keep the unit at least 3 m away from electronic
devices that generate electromagnetic waves, and
install a protection tube for the main power cable
and communication cable.
– Make sure that there is no device that can generate
electromagnetic waves. Otherwise, a malfunction
of the control system may occur. For example, the
indoor unit remote control sensor may not properly
receive signals near fluorescent lamps because of
interference.
• Be sure to install the outdoor unit in a safe place
where it is not affected by snowfall. The frame should
be installed in a place where the air inlet and heat
exchanger of the unit are not buried under snow.
• A ventilation system is required when the outdoor unit
is installed in a closed space or room, even though
R-410A is not poisonous or flammable.
• Install the railing around the outdoor unit to prevent
falling when installed at a high place.
• Avoid installation near exhaust pipes and ventilating
openings exposed to corrosive gas, sulfur oxide,
ammonia, or sulfur gas herbicide. Installations near
these places require anticorrosive treatments. Contact
the manufacturer to avoid corrosion of copper pipes or
soldered parts.
• Depending on the power supply, electric noise or
unstable voltage may happen after malfunctions of the
electrical parts or the control system particularly on
ships or other places using generators.
