• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air
conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.

Selectthe best Location
Indoor unit
- There should not be any heat or steam near
the unit.
- Select a place where there are no obstacles
around the unit.
- Make sure that condensation drainage can
be conveniently routed away.
- Do not install near a doorway.
- Ensure that the gap between a wall and the
left (or right) of the unit is more than 4in.
The unit should be installed as high as possi-
ble on the wall, allowing a minimum of 8in
from ceiling.
- Use a metal detector to locate studs to pre-
vent unnecessary damage to the wall.
* Recommended height 6.5ft from the floor
* The feature can be changed according to the
type of model.
Outdoor unit
- If an awning is built over the unit to prevent
direct sunlight or rain exposure, make sure
that heat radiation from the condenser is not
restricted.
- Ensure that the space around the back side
and other sides is more than 12in. The space
in front of the unit should be more than 28in.
- Do not place animals and plants in the path
of the warm air.
- Take the weight of the air conditioner into ac-
count and select a place where noise and vi-
bration are minimum.
- Select a place where the warm air and noise
from the air conditioner do not disturb neigh-
bors.

INSTALLATION

ENGLISH
Fixing Installation Plate
The wall you select should be strong and solid
enough to prevent vibration
1Mount the installation plate on the wall with
type "A" screws.
- Mount the installation plate horizontally by
aligning the centerline using Horizontal
meter .
2Measure the wall and mark the centerline.
It is also important to use caution
concerning the location of the installation
plate. Routing of the wiring to power outlets
is through the walls typically. Drilling the
hole through the wall for piping
connections must be done safely.
Drill aHole in the Wall
- Drill the piping hole with a ø65mm hole core
drill. Drill the piping hole at either the right or
the left with the hole slightly slanted to the
outdoor side.
Flaring Work
Main cause for gas leakage is due to defect of
flaring work. Carry out correct flaring work in
the following procedure.
1Use the piping kit accessory or the pipes
purchased locally.
2Measure the distance between the indoor
and the outdoor unit.
3Cut the pipes a little longer than measured
distance.
4Cut the cable 1.5m (4.9 ft) longer than the
pipe length.
CAUTION
Use the sleeve to prevent damage for
tube assembly.
