2. Place and Space for Installation
●
Choose a place as cool as possible. The place
should be well ventilated, and the intake air should
not be hotter than the outside temperature. (max.
45 °C)
●
Avoid the vicinity of heat sources, exhaust fans,
etc. (Fig. 2-1)
●
Required space around the outdoor unit for free air
flow and servicing is given in Fig. 2-2.
When using the Dual System Kit, be sure to keep a
separation of 25 cm as minimum between the air
intake of the outdoor unit (rear surface) and wall or
fence for maintenance work.
To avoid the effects of humidity and ground moisture,
the unit should be placed on concrete blocks or slab
at least 10 cm high above ground level. (Fig. 2-3)
The unit must be level and be anchored securely to its
base with anchor bolts or the like. An unsteady
foundation will cause abnormal noise and vibration.
(Fig. 2-3)
Depending on the ambient temperature during
operation of the outdoor unit, the dews may
adhere or may be frozen onto the service valves.
When the outdoor unit is to be installed in a place
where these dew drops may cause some
problem, provide the heat insulation for the
service valves or provide a plate under the
service valves to receive the dew drops.
