SELECTING INSTALLATION LOCATION OF SIDE DISCHARGE - OUTDOOR UNIT
CONSIDERATIONS FOR SELECTING INSTALLATION LOCATION
Select installation location which is close to the indoor unit.
Select the installation location of outdoor unit which is able to support operating weight
of outdoor unit, and not cause vibration.
Select the installation location of outdoor unit which is far away from the direct
sunlight.
Select the installation location of outdoor unit which is far away from heat sources,
steam or flammable gas.
Select the installation location of outdoor unit which is free of dust or any material,
which can cause clogging of condenser coil. When installing unit on the ground, select
a location not subjected to flooding.
Avoid installation location which is full of oil vapors which may result in malfunction.
Avoid installation location which is full of sulfuric gas which may result in malfunction.
Select installation location where the operation noise and discharged air are not
disruptive to your neighbors.
When the installation is made on the rooftop or other places subject to strong wind :
When the outdoor unit is to be installed on the rooftop or at the places where there are no other
buildings around. it is required to avoid the strong wind from blowing directly into the air outlet of the
outdoor unit so as to prevent the negative impacts on cooling performances due to insufficient airflow
of the outdoor unit heat exchanger and to prevent from faulty performances.
When there are walls in the vicinity, the air outlet
should face the wall and keep a space of 500mm
from the wall.
When the air outlet is affected by the strong wind,
the installation position should be changed so as
to make the air outlet at a straight angle from the
wind direction.

SELECTING INSTALLATION LOCATION OF SIDE DISCHARGE - OUTDOOR UNIT
9.3 Minimum Clearances When Selecting Installation Location for Single Outdoor Unit Installation
Minimum Clearances When Selecting Installation Location for Serial Installation
of More Than One Outdoor Unit
Select installation location which allows the minimum clearances shown in the figures for free
air circulation and easy accessibility for service and maintenance :
The front of outdoor unit ( air outlet )
should be away from any obstacle by 500 mm or more to ensure free air circulation.
The back of outdoor unit ( air inlet )
should be away from any obstacle by 160 mm or more. This distance is built in the design of wall support
to ensure free air circulation.
The left side of outdoor unit
should by away from any obstacle by 400 mm or more to ensure easy access to refrigerant and electrical
connections.
The right side of outdoor unit ( air inlet )
should be away from any obstacle by 250 mm or more to ensure free air circulation.

13.1 PREPARATION STEPS
STEP (1): MAKING WALL HOLE
PRECAUTIONS
Before making a hole, check carefully the following points :
No studs or pipes are directly run behind the spot to be cut.
No electrical wiring or conduits are located.
- Drill a hole of 80 mm to pass the refrigerant lines, drain hose
and electrical cables.
Decide the piping hole position according to the location of
piping direction. Mark the desired drilling point.
When making wall hole, make sure to drill outwards at a
downward angle, so that the height difference between the
entrance and exit of the hole is at least 5-10 mm.
Step (2): Cutting Sleeve For Wall Hole
•Measure the thickness of the wall from the inside edge to
the outside edge and cut PVC pipe at a slight angle 6mm
shorter than the thickness of the wall.
Step (3): Mounting Sleeve Into Wall Hole
•After making hole, a sleeve must be mounted into wall hole
and its width to be equal to wall thickness to pass
refrigerant lines, drain hose and electrical cables through it.
