2.3 Unit installation caution
The unit can be installed on the ground or on a suitable roof, but enough ven
ti
la
ti
on volume should be
ensured in both cases.
The unit should not be installed where noise and vibra
ti
on could cause problems.
.
The installed unit should be sheltered from direct sunlight as much as possible, and be far away from
boiler
fl
ues and dusty ambient air which may erode condenser coils and copper tube parts of the unit
.
Protective
measures of isola
ti
on should be taken, such as rail guards to avoid accidental damage.
The height of the installa
ti
on founda
ti
on for the unit should not be less than 100mm, and
fl
oor drains
are required in installa
ti
on sites, to ensure smooth drainage and remove any seepage.
In case of installation on the ground, the steel base of the unit should be located on
a
concrete
founda
ti
on, and the concrete plinth should extend below frozen soil layer. The founda
ti
on of the unit
should not be connected to the founda
ti
on of the building, t
o prevent transfer of noise and vibration.
The base of the unit is pro vided with installa
ti
on holes, which can be used t
o connect the unit firmly
to the foundation.
In case of installa
ti
on on a roof, the roof must possess enough strength to sustain weight of the unit
and maintenance personnel. The unit can be supported on concrete founda
ti
ons or channel steel frames
similar to those used in the unit installa
ti
on on the ground. The load-bearing channel steel must be in
alignment with the installa
ti
on holes of the unit damper, and the channel steel should posses enough
width for installing the damper.
Consult the building contractor, the architectural designer or
consulting engineer
in the case of
specialised installation requirements .
