INSTALLATION OF UNIT
Indoor Units Installation
The distance between the side and the sidewall cannot be less than 1 meter. In horizontal instal-
lation, ceiling hooks should be prepared for lifting the unit; in vertical installation, fix the unit on
the floor with bolts. Apply rubber cushions between the frame and its support to reduce vibra-
tion. The unit should be installed level, and the drain pan should be kept lean, The indoor unit
causes noise while operation, so it should be installed in a place where noise does not bother
people very much, in a room close to stairway, elevator or toilet, for example. A good way to
abate noise is to build a wall to isolate the machine from air-conditioned rooms, and close all
doors and windows of the unit room.
Therefore, the unit room should apply a return air system. To fix the return air piping, angle pipes
should be prepared on site. Besides, you ought to prevent noise for entering air-conditioned
rooms through the return air entrance.
Outdoor Unit Installation
The units can be installed on a proper ground or roof. The unit should be installed level with
enough air volume. In order to let air ow enter the condensation coil freely and without hot return
air, you should have sufficient space reserved when install the outdoor unit, as below table and
gure shows. Otherwise, air ow to the coil will get restrained, or discharge air will return. Conse-
quently there will be a capacity loss, power consumption will increase, and malfunction may
occur. Tall buildings around the unit may create downdraft affecting air discharge. Outdoor fan is
na axial flow fan, which does not an air pipe. Avoid installing the outdoor unit right below window
or between constructions, otherwise, noise caused by unit operation will go indoors. If the unit
can be easily approached by persons without permission, measures should be taken to protect it,
for example, setting up a fence. This will prevent the unit from sabotage or accidental damage,
and protect the control box from being opened and electrical components being exposed. Always
leave enough space between several outdoor units to benet their normal operation and your
maintenance.
Adjust the fin heat exchanger of the outdoor unit away from direct sunshine. Do not install the
unit in places full of dead leaves, insects or contaminations in case the heat exchanger is clogged
up. Ensure that the unit is set up level; the fan and compressor can operate normally, never in-
stall the unit in places easy to catch fire and exploded; be sure that no poisonous and dangerous
substance, such as oil steam or sulfur, exists in surrounding atmosphere keep the unit away from
boiler flue or any environment that can cause gin coil and other copper components to corrode. If
install the unit in places easy to be contaminated, you have to do more maintenance work.

The unit can be fixed on any flat surface that can hold 400 kg / m
pressure, no special pedestal
needed. Whether on roof or ground, rubber cushions should be applied between the unit frame
and its support to reduce vibration.
