The refrigerant volume is indicated on the unit nameplate
5 SELECTION OF INSTALLATION SITE
1) Units can be installed on the ground or proper place on a roof, provided that sufficient ventilation can be guaranteed.
2) Do not install the unit in a scenario with requirements on noise and vibration.
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.
4) If the unit can be achieved by 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) Install the unit on a foundation at least 200 mm high above the ground, where the floor drain is needed, to ensure that no
water accumulate.
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 solid 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
reliability.
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.
8) 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 cdischarge air should not influence the
surrounding environment.

2) Lifting: each lifting rope (belt) should be able to bear 4 times the weight of the unit. Check the lifting hook and ensure that it is
firmly attached to the unit. To avoid damages to the unit, a protective block made of wood , cloth or hard paper should be placed
between the unit and rope when lifting, and its thickness should be 50mm or more. It is strictly forbidden to stand under the machine
when it is hoisted.
