Installation manual

If any refrigerant has leaked out during the installation
work, ventilate the room.
The refrigerant produces a toxic gas if exposed to
flames.

After all installation is complete, check to make sure
that no refrigerant is leaking.
The refrigerant produces a toxic gas if exposed to
flames.

When installing or relocating the system, be sure to keep the
refrigerant circuit free from substances other than the specified
refrigerant (R410A), such as air.
Any presence of air or other foreign substance in the refrigerant
circuit causes an abnormal pressure rise or rupture, resulting in
injury.

During pump down operation, stop the compressor before
removing the refrigerant piping.
If the compressor is still running and the stop valve is open
during pump-down, air will be sucked in when the refrigerant
piping is removed, causing abnormal pressure in the freezer
cycle which will lead to breakage and even to injury.

During installation, attach the refrigerant piping securely before
running the compressor.
If the compressor is not attached and the stop valve is open
during pump-down, air will be sucked in when the compressor is
running, causing abnormal pressure in the freezer cycle which
will lead to breakage and even to injury.

Be sure to establish an earth. Do not earth the unit to a
utility pipe, surge absorber, or telephone earth.
Incomplete earth may cause electrical shock. A high
surge current from lightning or other sources may
cause damage to the air conditioner.

Be sure to install an earth leakage breaker.
Failure to do so may cause electrical shock.

CAUTION

Do not install the air conditioner in a place where there
is danger of exposure to inflammable gas leakage.
If the gas leaks and builds up around the unit, it may
catch fire.

Establish drain piping according to the instructions of this
manual.
Inadequate piping may cause flooding.

Note for installing the outdoor unit. (For heat pump model only.)
In cold areas where the outside air temperature remains below
or around the freezing-point for a few days, the outdoor unit's
drain may freeze. If so, it is recommended to install an electric
heater in order to protect drain from freezing.

Tighten the flare nut according to the specified method such as
with a torque wrench.
If the flare nut is tightened too hard, the flare nut may crack after
a long time and cause refrigerant leakage.

FOR

 

SELECTING

 

THE

 

LOCATION

1

Choose a place solid enough to bear the weight and vibration of
the unit, where the operation noise will not be amplified.

2

Choose a location where the hot air discharged from the unit or
the operation noise will not cause a nuisance to the neighbours
of the user.

3

Avoid places near a bedroom and the like, so that the operation
noise will cause no trouble.

4

There must be sufficient space for carrying the unit into and out
of the site.

5

There must be sufficient space for air passage and no
obstructions around the air inlet and the air outlet.

6

The site must be free from the possibility of flammable gas
leakage in a nearby place.

Locate the unit so that the noise and the discharged hot air will
not annoy the neighbours.

7

Install units, power cords and inter-unit cables at least 3 m away
from television and radio sets. This is to prevent interference to
images and sounds.

Depending on radio wave conditions, electromagnetic
interference may still occur even if installed more than 3 m away.

8

In coastal areas or other places with salty atmosphere of sulfate
gas, corrosion may shorten the life of the air conditioner.

9

Since drain flows out of the outdoor unit, do not place anything
under the unit which must be kept away from moisture.

Make sure to provide adequate measures in order to
prevent that the outdoor unit will be used as a shelter
by small animals.

Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.

NOTE

Units cannot be installed hanging from ceiling or
stacked.
