Installation of Indoor Unit
Installation of Mounting Plate
1. Mounting plate should be installed horizontally. As the water tray's outlet for the indoor unit is two-way
type, during installation, the indoor unit should slightly slant to water tray's outlet for smooth drainage of
condensate.
2.Fix the mounting plate on the wall with screws.
3.Be sure that the mounting plate has been fixed firmly enough to withstand about 132.3 lb. Meanwhile, the
weight should be evenly shared by each screw.

Installation of Indoor Unit
The piping can be output from right, right rear, left
or left rear.
When routing the piping and wiring from the left
or right side of indoor unit, cut off the tailings
from the chassis when necessary(As shown in Fig.7)
Cut off tailing 1 when routing the wiring only;
Cut off tailing 1 and tailing 2 when routing
both the wiring and piping.
Take out the piping from body case;wrap the piping,
power cords, drain hose with the tape and then make
them pass through the piping hole. (As shown in Fig.8)
Hang the mounting slots of the indoor unit on the
upper hooks of the mounting plate and check if it is
firm enough. (As shown in Fig.9)
The installation site should be 98 3/7 inch or more
above the floor
.
Installation of Connection Pipe
Align the center of the pipe flare with the related valve.
Screw in the flare nut by hand and then tighten the
nut with spanner and torque wrench by referring to the
following:
NOTE: Connect the connection pipe to indoor unit at first and then to outdoor unit. Handle pi-
ping bending with care. Do not damage the connection pipe. Ensure that the joint nut
is tightened firmly, otherwise, it may cause leakage.

● Use vacuum pump
1. Connect the charging hose of manifold valve to charging
port of low-pressure valve. Both high-pressure valve and
low-pressure valve must be tighten up).
2. Connect joint of charging hose to vacuum pump.
3. Fully open Lo （low pressure ）handle of manifold valve
and start the vacuum pump for vacuum pumping.
4. Usually the vacuum pumping time of 2600W AC is about
15min. The vacuum pumping time of 5000W AC is about
20min. The vacuum pumping time of 7200W AC is about
30min. Make sure the pressure is -1.0X105pa (-76cmHg).
When vacuum pumping is finished, close Lo （low pressure ）
handle of manifold valve completely to stop the vacuum pump.
