5.2 Opening The Unit
5.2.1 Opening the outdoor unit
Removal of all screws on the right front side
plate;Put the left hand into the handle position to
prevent the right front side plate from falling, and
prepare for pulling out;
Press the right hand on the corner of the right front
side plate and pull it down, and pull the left hand
outward at the same time;
After the top rib comes out of the top cover, take out
the right front side plate.
5.3 Mounting The Outdoor Unit
5.3.1 Preparing the structure for installation
The base of the outdoor unit must use the solid
concrete surface as the cement base or the steel
beam frame base.
The base must be completely level to ensure that
every point of contact is even.
During installation, make sure the base supports the
vertical folds of the front and back under plates of the
chassis directly as the vertical folds of the front and
back under plates are unit where the actual support
for the unit load is.
No gravel layer is required when the base is built on
the roof surface, but the sand and cement on the
concrete surface must be level, and the base should
be chamfered along the edge.
A water drainage ditch should be set around the
base to drain the water around the equipment.
Potential risk: slip.
Check the load-bearing capacity of the roof to make
sure it can support the load.
When you choose to install the piping from the
bottom, the base height should be above 200mm.
Make sure the base where the unit is installed is
strong enough to prevent vibrations and noise.
Use six bolts (M8) to secure the
unit in place. Best is to screw in
the ground bolt until it is
embedded in the base surface
by at least 3 threads.
Please refer to the figure below for the installation
position of bolts.

5.3.2 Outdoor unit installation space
Make sure there is sufficient space around the unit for
maintenance work, and the minimum space for air inlet
and air outlet is reserved (see below to select a feasible
method).
In all installation examples in this chapter, the
direction of connecting pipe for outdoor unit
installation is forward or downward.
When the rear pipe is connected and installed,
the installation space on the right side of the
outdoor unit shall be at least 250mm;
When two or more outdoor units are installed
side by side, the distance between two adjacent
outdoor units must be greater than 200mm;
For the installation space of the unit, the
maintenance space and smooth ventilation of
the unit shall be considered, and an installation
method shall be selected according to the actual
situation.
