6.2 Moving and Installation
Since the center of gravity of the unit is not at its actual
physical center, please be careful when lifting it using a sling.
Never directly hold onto the inlet of the outdoor unit, to
prevent it from deforming.
Do not touch the fan with your hands or any other objects.
Do not lean the unit more than 45, and do not lay it sideways.
Create a concrete foundation accoding to the specifications
of the outdoor units. (Refer to Fig. 6-5)
Firmly fasten the feet of this unit with bolts, to prevent it from
collapsing in case of earthquake or strong winds. (Refer to
Fig. 6-5)

7. INSTALL THE CONNECTING PIPE

Check to ensure that the height drop between the indoor unit
and outdoor unit, the length of refrigerant pipe, and the number
of bends meet the following requirements:

Pipe Connection Procedure
CAUTION
All field piping must be performed by a licensed
refrigeration technician, and must comply with the
relevant local and national codes.
Do not let air, dust, or other impurities fall into the pipe
system during the process of installation. Connecting
pipes should not be installed until the indoor and
outdoor units have already been fixed into place.
Keep the connecting pipes dry, and do not let moisture
inside during installation.
Heat insulation work should be installed properly and
fully, on both sides of the gas piping and the liquid
piping. Otherwise, there can be a risk of water leakage.
Drill a hole into the wall (suitable for just the size of the wall
1
conduit), and set the fittings (such as the wall conduit and its
cover) onto the wall.
Bind the connecting pipe and the cables together tightly with
2
the use of binding tape.
Pass the bound connecting pipe through the wall conduit from
outside. Be careful with the pipe movement, to avoid doing
damage to the tubing.
3 Connect the pipes. Refer to "How to Connect the Pipes" for
further details.
Expel all air with a vacuum pump. Refer to "How to Expel the
4
Air with a Vacuum Pump" for details.
Open the stop valves of the outdoor unit, to set the refrigerant
5
pipe connecting the indoor unit with the outdoor unit in fluent
flow.
Check for leakage. Check all joints with a leak detector or
6
soapy water.
7 Cover the joints of the connecting pipe with soundproof/
insulating sheaths (fittings), and bind it well with the tapes to
prevent leakage.
CAUTION
Be sure that the insulating materials cover all of the
exposed parts of the flare pipe joints and refrigerant pipes
on the liquid-side and the gas-side. Ensure that there is
no gap between these layers.
Improper insulation may cause water condensation.
