Main cause for refrigerant leakage is due to defect
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 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.

For the drain joint with the seal(Fig.11 (A)), first
fit the seal onto the drain joint, then insert the
drain joint into the base pan hole of outdoor unit,
rotate 90
to securely assemble them. To install
drain joint as shown in Fig.11 (B), insert the drain
joint into the base pan hole of outdoor unit until it
remains fixed with a clicking sound. Connecting
the drain joint with an extension drain hose (Locally
purchased), in case of the water draining off the
outdoor unit during the heating mode.
NOTE:
In cold areas, do not use a drain hose with
the outdoor unit.(otherwise, drain water may freeze)
NOTE:
The drain joint is slightly different
according to the different outdoor unit.

Settlement of outdoor unit
NOTE:
The outdoor unit you purchase may be like one
of the following. Install the outdoor unit according to the
dimension as indicated in the table below:

Air inlet
Fig.8
Install the outdoor unit on a rigid base to
prevent increasing noise level and vibration.
Determine the air outlet direction where the
discharged air is not blocked.
In the case that the installation place is exposed
to strong wind such as a seaside, make sure the
fan operating properly by putting the unit lengthwise
along the wall or using a dust or shield plates.
Specially in windy area, install the unit to prevent the
admission of wind. If need suspending installation,
the installation bracket should accord with technique
requirement in the installation bracket diagram.
The installation wall should be solid brick, concrete or
the same intensity construction, or actions to reinforce,
damping supporting should be taken. The connection
between bracket and wall, bracket and the air conditioner
should be firm, stable and reliable.
Be sure there is no obstacle which block radiating air.

OUTDOOR UNIT INSTALLATION
Outdoor installation precaution
1. Pass the piping through the hole in the wall.
2. Hook the indoor unit onto the upper portion
of installation plate(Engage the indoor unit with
the upper edge of the installation plate). Ensure
the hooks are properly seated on the installation
plate by moving it in left and right.
3. Piping can easily be made by lifting the indoor
unit with a cushioning material between the
indoor unit and the wall. Get it out after finish
piping. When use a wall embedded pipe, the
indoor unit can be moved to the left or right for
30~50mm(model dependent), which offers
sufficient space to arrange the pipes and ensure
the indoor unit fully close to the wall after installation.
4. Press the lower left and right side of the unit
against the installation plate until hooks
engages with the their slots.

NOTE:
Connective pipe length will affect the
capacity and energy efficiency of the unit. The
nominal efficiency is tested basing on the pipe
length of 5 meters. Consult the technicians to
purchase proper size connective pipe for your
machine..
