Outdoor Unit Installation Manual

INSTALLATION OF OUTDOOR UNIT
„ Installation Location
• A place which can bear the weight of the outdoor unit and does not cause
an increase in noise level and vibration.
• A place where the operation noise and air discharge do not disturb
neighbours.
• A place which is not exposed to strong wind.
• A place free of combustible gas.
• A place which does not block a passageway.
• A place where the drain water does not cause any problems.
• A place where there are no obstructions near its air intake or air outlet.
„ Precautions for Installation
• When the outdoor unit is to be installed in an elevated position, be sure to
secure its feet.
• If the outdoor unit is to be mounted on a wall, make sure the base plate
supporting it is sturdy enough.
• The base plate should be designed and manufactured to maintain its
strength over a long d of time, and sufficient consideration should be given
to ensure that the outdoor unit will not fall.
• When the outdoor unit is installed in a place that is always exposed to
strong wind such as a coastal area or on a high story of a building, secure
the normal fan operation using a duct or a wind shield.
• Especially in windy areas, install the unit in such a way as to prevent the
admission of wind.
• When the outdoor unit is to be mounted high on a wall, take particular care
to ensure that parts do not fall, and that the installer is protected.
• When doing installation work at ground level, it is usual to make wiring and
pipe connections to the indoor units first, and then to make connections to
the outdoor units.
However, if outdoor work is difficult you can change the procedure.
For example, by making adjustments to the wiring and piping lengths on the
inside (rather than the outside).
Necessary Space for Installation
If you need to install the outdoor unit in a location where there are some
obstructions or a wall, secure sufficient space as shown in the figure below.
The cooling/heating effect may be reduced by 10%.
Draining Off the Water from the Outdoor Unit
Install 5 waterproof rubber caps and the drain nipple to drain off the water
from the outdoor unit.
• Seal the knock-out holes and screw/thread areas tightly using a silicon
adhesive or a caulking compound.
• Use a drain pan to apply a centralized drain.
Installation in Regions with Snowfall and Cold Temperatures
Do not use waterproof rubber caps or a drain nipple.
• If you need to install the outdoor unit in a location where there is a possibility
of the drain freezing, pay close attention so that the drain does not become
frozen.
• To protect the outdoor unit from snow, install the outdoor unit on a holding
frame, and attach a snow protection hood and plate.
• Keep the outdoor unit at least 500mm above the snow accumulation line.
Fixing the Outdoor Unit
Fix the outdoor unit using attachment bolts.
• Use 8mm or 10mm anchor bolts and nuts.
• Do not allow the attachment bolts to protrude by more than 15mm.
• Install the outdoor unit at ground level.
• Attach the vibration-proof rubber pads under the fixing legs.
Installation in the following places may result in trouble:
• A place with a lot of machine oil.
• A place with saline-rich atmosphere such as a coastal area.
• A place with high level of sulfide gas.
• A place where high-frequency waves are likely to be generated, such as
from audio equipment, welders, or medical equipment.
Do not install the unit in such places.
