2). If the wall is made of brick, concrete or
the like, drill eight (8) 5mm diameter holes
in the wall. Insert Clip anchor for appropriate
mounting screws.
3). Fit the installation plate on the wall with eight
(8) type “A” screws.
Correct orientation
of Installation Plate
Fit the Installation Plate and drill holes in the wall according to the wall structure and corresponding
mounting points on the installation plate.

1. Pass the piping through the hole in the wall.
2. Put the upper claw at the back of the indoor unit on
the upper hook of the installation plate, move the
indoor unit from side to side to see that it is securely
hooked.
3. Piping can easily be made by lifting the indoor unit
with a cushioning material between the indoor unit
and the wall. Remove cushioning material after finish
piping.
4. Push the lower part of the indoor unit up on the wall,
Then move the indoor unit from side to side, up and
down to check if it is hooked securely.

5. Piping and wrapping
Bundle the tubing, connecting cable, and
drain hose with tape securely and
evenly as shown in Fig.11.
Because the condensed water from rear
of the indoor unit is gathered in ponding
box and is piped out of room. Do not put
anything else in this box.

Connect the indoor unit first, then the outdoor unit.
Do not allow the piping to be exposed out from the back of the indoor unit.
Be careful not to let the drain hose become slack.
Heat insulate the c piping.
Be sure that the drain hose is located at the lowest side of the bundle. Locating
at the upper side can cause drain pan to overflow inside the unit.
Never cross connect or inter wind the power wire with any other wiring.
Run the drain hose sloped downward to drain out the condensed water smoothly.

CAUTION
Install the outdoor unit on a rigid base to prevent noise and vibration.
Select the air outlet direction so that discharged air is not blocked.
In the case where the installation location is exposed to strong winds,
make sure the fan operates properly by putting the unit lengthwise along the wall
or by using a shield to minimise wind exposure.
Especially in windy areas, install the unit to minimise exposure to wind.
For suspended installations, the installation bracket should follow with technique
requirement in the installation bracket diagram. The installation wall should be solid
brick, concrete or of same construction,
or reinforced to minimise movement or vibration.
The connection between the wall bracket and the
air conditioner should be firm, stable and reliable.
Ensure there lare no obstacles which block
flow air.
