5.1 Units can be installed on the ground or proper place on a roof,
provided that sufficient ventilation can be guaranteed.
5.2 Do not install the unit in a scenario with requirements on noise
and vibration.
5.3 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.
5.4 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.
5.5 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.
5.6 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.
5.7 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.
5.8 For other special requirements for installation, please consult
the building contractor, architectural designer or other
professionals.
