6.5 Moving and installation
Since the gravity center of the unit is not at its physical
center, so please be careful when lifting it with a sling.
Never hold the inlet of the outdoor unit to prevent it from
deforming.
Do not touch the fan with hands or other objects.
Do not lean it more than 45, and do not lay it sidelong.
Make concrete foundation accoding to the sepecif-ications of
the outdoor units.(Refer to Fig.6-15)
Fasten the feet of this unit with bolts firmly to prevent it from
collapsing in case of earthquake or strong wind.(Refer to
Fig.6-15)
Fix with bolt
NOTE
All the pictures in this manual are for explanation
purpose only. They may be slightly different from the air
conditioner you purchased(depend on model).The
actual shape shall prevail.
Concrete Foundation
1. Foundation could be on flat and is recommended be 100-300mm
higher than ground level.
2.Install a drainage around foundation for smooth drain
3.When installing the outdoor unit fix the unit by anchor bolts of M10
4.When installing the unit on a roof or a veranda,
sometimes turns to ice on a cold morning. Therefore, avoid
draining in an area that people often use because it is slippery.

7. INSTALL THE CONNECTING PIPE
Check whether the height drop between the indoor unit and
outdoor unit, the length of refrigerant pipe, and the number of
the bends meet the following requirements:
(The number of the bends less than 15.)

The Procedure of Connecting Pipes
7.1
CAUTION
All field piping must be provided by a licensed
refrigeration technician and must comply with the
relevant local and national codes.
Do not let air, dust, or other impurities fall in the pipe
system during the time of installation.
The connecting pipe should not be installed until the
indoor and outdoor units have been fixed already.
Keep the connecting pipe dry, and do not let moisture in
during installation.
Execute heat insulation work completely on both sides
of the gas piping and the liquid piping. Otherwise, this
can sometimes result in water leakage.
1
Drill a hole in the wall (suitable just for the size of the wall
conduit), then set on the fittings such as the wall conduit and
its cover.
Bind the connecting pipe and the cables together tightly with
2
binding tapes.
Pass the bound connecting pipe through the wall conduct
from outside. Be careful of the pipe allocation to do on
damage to the tubing.
Connect the pipes. Refer to "How to Connect the pipes" for
3
details.
4
Expel the air with a vacuum pump. Refer to "How to expel the
air with a vacuum pump" for details.
open the stop values of the outdoor unit to make the
5
refrigerant pipe connecting the indoor unit with the outdoor
unit in fluent flow.
6
Check the leakage. Check all the joints with the leak detector
or soap water.
Cover the joints of the connecting pipe with the soundproof /
7
insulating sheath (fittings), and bind it well with the tapes to
prevent leakage.
