Installation requirements of outdoor unit in
space with shutters
When the outdoor unit is installed in the space with
shutters, the distance between the air outlet and the
shutters must be ≤ 0.5m; When the distance
between the air outlet and the shutter cannot meet
the requirements, the air duct must be installed。
Unit:mm

The shutter opening rate of the shutter is greater
than 90%, and the shutter angle is less than 15 °.

≤15°
CAUTION
The installation space shown above is for
refrigeration operation under the assumption
that the outdoor temperature is 35°C. If the
outdoor temperature exceeds 35°C or the
heat load is large, and all outdoor units
operate in excess of capacity, the space
required on the air inlet side shall be
increased.
If the air duct needs to be added when the
above installation space conditions are not
met, please refer to "Installation of outdoor
unit ducting" for the installation requirements
and methods.
5.3.3 Vibration Reduction of outdoor unit
The ODU shall be firmly fixed, and a thick rubber plate
or corrugated shock-absorbing rubber cushion with a
thickness of more than 20mm and a width of more
than 100mm shall be placed between the unit and the
foundation. The shock-absorbing rubber cushion
cannot only support the four corners of the unit, and
the setting requirements are shown in the figure below.

CAUTION
During the test, do not exert a force greater
than the maximum allowed pressure on the
product (as shown on the nameplate).
Take appropriate precautions to prevent
refrigerant
leakage.
Ventilate
immediately if the refrigerant leaks. Possible
risk (An excessively high concentration of
refrigerant in an enclosed area can lead to
anoxia (oxygen deficiency); the refrigerant
gas may produce a toxic gas if it comes in
contact with fire.)
Refrigerant must be recovered. Do not

professional fluorine extraction equipment to
extract the refrigerant from the unit.
NOTE
Make sure the refrigerant piping is installed in
accordance with the applicable law.
Make sure the piping and connections are
not placed under pressure.
After all the piping connections have been
completed, check to make sure there is no
gas leak. Use nitrogen to conduct the leak
check for gas.
CAUTION
Clean and new pipes shall be used for
refrigerant piping, water and foreign matters
shall not enter the pipe during construction; If
water and foreign matters enter, be sure to
flush the pipeline with nitrogen.
