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.
Fixing the outdoor unit in place
Fix the outdoor unit with anchor bolts. Make sure that
the anchor bolts are 20 mm or higher from the base
surface.

CAUTION
∙ Install a drain outlet at the lowest end around the
base for the outdoor unit drainage.
∙ When installing the outdoor unit on the roof,
waterproof the unit and check ceiling strength.
