Capacity is based on standard length and maximum allowance
length is on the basis of reliability.
Oil trap should be installed every 5~7 metres.
When the connecting pipe is longer than 5 metres, additional
refrigerant should be added into the unit according to the
above table through the service port on the “LO” valve on
outdoor unit.

Note:
1. Fit the Installation Plate
1). Fit the installation plate horizontally
on structural parts of the wall with
spaces around the installation plate.
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.
(Dimensions are in “mm” unless otherwise stated)

the diagram detailed in Fig.5. Drill
one (1) hole ( 65mm <998*322 or
95mm >1250*325) slanting slightly
to outdoor side.
2. Always use wall hole conduit when
drilling metal grid, metal plate or the like.

1. For the left-hand and right-hand piping, remove the pipe cover from the side panel.
2. For the rear-right-hand and rear-left-hand piping, install the piping as shown. Bend the
connecting pipe to be laid at a height of 43mm or less from the wall.
3. Fix the end of the connecting pipe. (Refer to Tightening Connection in REFRIGERANT

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.

3. Connecting Pipe and Drainage Installation
1. Run the drain hose sloping downward. Do not install the drain hose as illustrated below.
2. When connecting an extension drain hose, insulate the connecting part of the extension
drain hose with a shield pipe, do not let the drain hose become slack.

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.

Fig.11
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 connecting 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.

INSTALLATION
REFRIGERANT PIPE CONNECTION
Securing of outdoor unit
Anchor the outdoor unit with
a bolt and nut 10 or 8 tightly
and horizontally on a concrete
or rigid mount.
If a drain elbow is used, the unit should be placed
on a stand which is taller than 3cm.
If the unit is used in an area where temperature
O
falls below 0 C for 2 or 3 days in succession, it
is recommended not to use a drain elbow, as the
drain water may freeze and the fan will not rotate.
Fit the seal into the drain elbow, then insert
the drain joint into the base pan hole of the
outdoor unit, rotate 90 to secure. Connect
the drain joint with an extension drain hose
(Locally purchased), in instances where you
need to drain condensed water away from the unit.

Roughness
Burr
Main cause for refrigerant leakage
is due to defects in the flaring work.
Carry out correct flaring work
using the following procedure:
A: Cut the pipes and the cable.
1. Use the piping kit accessory (if applicable) or pipes
purchased locally.
2. Measure the distance between the indoor and the outdoor unit.
3. Cut the pipes a little longer than the measured distance.
4. Cut the cable 1.5m longer than the pipe length.

B: Burr removal
1. Completely remove all burrs from the cut
cross section of pipe/tube.
2. Face the end of the copper pipe/tube in a
downward direction as you remove burrs in
order to avoid burrs dropping into the tubing.

having completed burr removal (Note: It is not
possible to put them on after flaring work).

D: Flaring work
Firmly hold copper pipe in a die according
to the dimension shown in the table below.
Carry out flaring work using flaring tool as
shown below.
Caution
Align the center of the pipes.
Sufficiently tighten the flare
nut with fingers, and then tighten
it with a spanner and torque wrench
as shown.

Excessive torque can break nut
depending on installation conditions.
