Location and Preparation of Units
Indoor Unit
1. Select a convenient location that
allows the air to reach every corner
of the room and where it is easy to
route the refrigerant tubing, wiring
and drain to the outside.
2. The ceiling construction should be
strong enough to support the
weight of the unit.
3. The refrigerant tubing, drain piping
and wiring conduit are connected
through the wall.
4. Refrigerant tubes between the
indoor and the outdoor units and
drain pipes should be as short as
possible (Figure 1).
5. If a refrigerant charge adjustment is
necessary, follow the Installation
Manual for the Outdoor Unit.
Outdoor Unit
See instructions for location and
preparation of the unit in the Installation
Manual for the Outdoor Unit.
Installation Method:
Indoor Unit
After selecting the location to place
the unit, follow these steps:
1. Make a hole in the wall to route
tubing and wiring through a locally
purchased PVC pipe. The hole
should slope downwards slightly,
towards the outside (Figure 2).
Figure 1
2. Before cutting, check that no pipes
or studs are directly behind the
place to be cut. Avoid areas where
electrical wiring or conduits are
located.
3. Hang the unit on a solid and level
roof. Noise, vibration or leakage
could occur on and unstable
foundation (Figure 3,4).
For correct installation of duct
work see (Figure 6).
4. Support the unit solidly.
5. To have access to electrical
terminals, remove the right side
junction box (Figure 2).
6. Note that refrigerant tubing,
interconnecting wiring and drain
hose should go through the wall.
Shape these items so that they will
easily fit through the wall.
