12.Installation
12.1 Location of Installation
Before installation, check the following points.
1) Design the air distribution of the air conditioner into a room
in consideration with room structure, numbers of occupants
and the layout of furniture.
2) Install the air conditioner in such a place, from where the air
can be distributed throughout a room without any
interruption by furniture and instruments.
3) Install the air conditioner in such a place where electricity or
condenser water can be supplied easily and condensation
disposal can be easily extracted outside.
4) Fix the air conditioner in such a place which is strong enough
to bear its weight and as flat as possible.
5) Install the air conditioner in such a place which is wide
enough to do usual maintenance and service work easily.
6) In case the air conditioner is enclosed, provide space for
return air and leave sufficient space around the unit for
maintenance and inspection.
12.2 Bring in the Unit as Near as Possible
to the Position Installed
When hanging the unit, refer to the following table.

12.3 Service Spacing
Leave service spacing as large as possible around the air
conditioner for connecting the pipes, etc. In particular, at the
front of the unit, space is required for operation, as the control
panel, various pressure switches, thermostat, and switch box
are attached to the front of the unit.
Furthermore, the space for cleaning the cooling tubes of the
condenser must also be left.
The minimum service spacing for models is illustrated in the
respective dimension drawings.
12.4 Fixing the Air Conditioner
Firmly fix the air conditioner to the wall or the foundation to
prevent the unit from falling down or swinging due to rolling or
pitching of the ship body.
As shown in the figure, fix the unit at its base frame at 4 points
and at its rear plate of the casing at 4 points with bolts and nuts.
12.5 Providing the Drain Piping to the Air
Conditioner
1) Connect drain pipes to upper and lower drain pipe
connections of the unit separately.
2) In case the drain pipes should be combined, do it at the
position which is lower than the lower drain pipe connection
to prevent condensation disposal from entering into the
lower drain pipe connection.
3) Do not connect both upper and lower drain pipes to the
condenser water piping.
4) Since the drain piping is connected to the unit on the suction-
air side of the fan, be sure to provide a trap at the drain
outlet.
Reference
¡ Volume of condensation is approx. 0.02~0.03 R/min. per
refrigeration ton in case of normal cooling.
12.6 Piping around the Air Conditioner
It is advisable to connect a short pipe between the air
conditioner and the stop valve
for easy replacement
of the sacrificial
anode plate,
maintenance and
inspection
of cooling tubes.
