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.

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 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) Install the unit on a foundation at least 200 mm high above the ground, where the floor drain is provided, to ensure that 

water does not 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 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.
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 cold and hot air should not influence 

the surrounding environment.
