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°
NOTE
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.

5.3.3 Vibration Reduction of outdoor unit
The outdoor unit 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.

5.4 Piping Installation
5.4.1 Things to note when connecting the
refrigerant piping
Make sure the refrigerant piping is installed in
accordance with the applicable law.
Make sure the piping and connections are not placed
under pressure.
5.4.2 Connect refrigerant piping
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.
Be careful when the pipeline passes through
the wall. Please cover both ends of the
pipeline with adhesive tape or rubber plug to
prevent foreign matters.
The pipe connection shall follow the following
principles: the shorter the connected pipe,
the smaller the height difference between
indoor and outdoor units, the less the pipe
bending angle, and the larger the bending
radius as much as possible.
When laying according to the predetermined
route, the pipe shall not be flattened. The
bending radius of the bending part must be
greater than 200mm. The connecting pipe
cannot be stretched or bent frequently. One
pipe cannot be bent at the same place for
more than 3 times at most.
Before the refrigerant piping is connected, make sure
the indoor units and outdoor units are installed
properly. Connecting refrigerant piping include:
● Connect refrigerant piping to outdoor unit
● Connect refrigerant piping to indoor unit (refer to the
installation manual of the indoor unit)
