TIPS FOR SAVING ENERGY
Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:
• 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.

INSTALLATION
Select the best Location
Fixing Installation Plate
- There should not be any heat or steam near
the unit.
- Select a place where there are no obstacles
around of the unit.
- Make sure that condensation drainage can
be conveniently routed away.
- Do not install near a doorway.
- Ensure that the interval between a wall and
the left (or right) of the unit is more than
100mm. The unit should be installed as high
as possible on the wall, allowing a minimum
of 200mm from ceiling.
- Use a metal detector to locate studs to prevent unnecessary damage to the wall.
The wall you select should be strong and solid
enough to prevent vibration
1 Mount the installation plate on the wall
with type "A" screws. If mounting the unit
on a concrete wall, use anchor bolts.
- Mount the installation plate horizontally
by aligning the centerline using Horizontal

Flaring Work
Main cause for gas leakage is due to defect of
flaring work. Carry out correct flaring work in
the following procedure.
- Remove flare nuts attached to indoor and
outdoor unit, then put them on pipe/tube
having completed burr removal.
(not possible to put them on after finishing
flare work)

Cut the pipes and the cable
1 Use the piping kit accessory or the pipes
purchased locally.
2 Measure the distance between the indoor

conditions are hot and humid.
4 Where a customer supplies his own specifications then these must be adhered to.
Finishing the indoor unit
installation
1 Mount the tubing holder in the original
positon.
2 Ensure that the hooks are properly seated
on the installation plate by moving it left
and right.
3 Press the lower left and right sides of the
unit against the installation plate until the
hooks engage into their slots (clicking
sound).
4 Finish the assembly by screwing the unit
to the installation plate by using two
pieces of type "C" screws. And assemble a
chassis cover.
Connecting the Cables
Indoor unit
Connect the cable to the indoor unit by connecting the wires to the terminals on the control board individually according to the outdoor
unit connection. (Ensure that the color of the
wires of the outdoor unit and the terminal No.
are the same as those of the indoor unit.)
1 Insert the connecting cable through the
bottom side of indoor unit and connect the
cable (You can see detail contents in 'Connecting the cables' section)
2 Secure the cable onto the control board
with the cable retainer.
3 Tape the tubing pipe, drain hose and the
connection cable. Be sure that the drain
hose is located at the lowest side of the
bundle. Locating at the upper side can
cause overflow from the drain pan through
the inside of the unit.
