3. INSTALLATION OF THE UNIT
3.1 Selection of installation sites
3.1.1 The unit can be installed on the ground or on the
suitable roof, but enough ventilation volume should be
ensured in both cases.
3.1.2 The unit should not be installed where noise and
vibration are required to a certain extent.
3.1.3 The installed unit should be sheltered from direct
sunlight as much as possible, and be far away from
boiler flues and ambient air which may erode condenser
coils and copper tube parts of the unit.
3.1.4 If the installed unit can be approached by
unauthorized persons, safety measures of isolation
should be taken, such as rail guards. These measures
will avoid artificial damages and accidental damages,
and prevent the control boxes from being opened leading
to exposure of electric components in operation.
3.1.5 The height of the installation foundation for the unit
should not be less than 300mm, and floor drains are
required in installation sites, to ensure smooth drainage
and remove any seeper.
3.1.6 In case of installation on the ground, the steel base
of the unit should be located on the concrete foundation,
and the concrete plinth should extend below frozen soil
layer. The foundation of the unit should not be connected
to the foundation of the building, to avoid affecting the
people due to transfer of noise and vibration. The base
of the unit is provided with installation holes, which can
be used to connect the unit and the foundation firmly.
3.1.7 In case of installation on the roof, the roof must
possess enough strength to sustain weight of the unit
and maintenance personnel. The unit can be supported
on concrete foundations or channel steel frames similar
to those used in the unit installation on the ground. The
load-bearing channel steel must be in alignment with the
installation holes of the unit damper, and the channel
steel should possess enough width for installing the
damper.
3.1.8 Consult the building contractor, the architectural
designer or other specialists about the cases with special
installation requirements.
The selected installation site of the unit should facilitate connection
of water pipes and wires, and be free from water inlet of oil fume,
steam or other heat sources. Besides, the noise of the unit and cold
and hot air should not influence the surrounding environment.
