5. PRECAUTIONS OF INSTALLATION
a. Units can be installed on the ground or proper place on a roof,
provided that sufficient ventilation can be guaranteed.
b. Do not install the unit in a scenario with requirements on noise
and vibration.
c. When installing the unit, take measures to avoid exposure to
direct sunlight, and keep the unit away from boiler pipeline and
surroundings which might corrode the condenser coil and copper
pipes.
d. If the unit is within the reach of unauthorized personnel, take
protective measures for safety considerations, such as installing
a fence. These measures can prevent man-caused or accidental
injuries, and can also prevent the electrical parts in operation
from being exposed when the main control box is opened.
e. Install the unit on a foundation at least 300 mm high above the
ground, where the floor drain is provided, to ensure that water
does not accumulate.
f. If installing the unit on the ground, put the steel base of the unit on
the concrete foundation, which must be as deep as into the frozen
soil layer. Ensure the installation foundation is separated from
buildings, as the noises and vibration of the unit may adversely
affect the latter. By means of the installation holes on the unit
base, the unit can be fastened on the foundation reliably.
g. If the unit is installed on a roof, the roof must be strong enough
to bear the weight of the unit and the weight of maintenance
personnel. The unit can be placed on the concrete and groove-
shaped steel frame, similar to the case when the unit is installed
on the ground. The weight-bearing groove-shaped steel must
match the installation holes of the shock absorber and is wide
enough to accommodate the shock absorber.
h. For other special requirements for installation, please consult the
building contractor, architectural designer or other professionals.
NOTE
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.
