Installation Precautions
1. The unit should be installed so that the inclination of any vertical surface does not exceed 5
degrees;
2. Do not install the outdoor unit directly on the ground;
3. The strength of the ordinary air-conditioning bracket may not apply to the unit. Please design or
select the frame according to the weight of the team;
4. If the mainframe is installed and fixed on the open balcony and the roof, it is necessary to lift the
unit. Pay attention to the following points when lifting:
4.1
Please use four or more soft slings to lift the handling unit;
4.2
To avoid scratching and deformation of the surface of the unit, please install the guard plate
on the surface of the team during lifting and loading;
4.3
Before final installation, it is necessary to check whether the foundation is correct or not, in
case it is wrong with the actual object.
4. User Water System Installation
4.1
The installation of the water system must meet the following principles:
4.1.1
Pipe length is as short as possible;
4.1.2
Pipe diameter must meet the requirements of the unit;
4.1.3
The elbows on the waterway are as few as possible, and the elbow radius is as large
as possible;
4.1.4
The thickness of the water pipe insulation layer meets the specified requirements;
4.1.5
Dust and debris should not enter the pipeline system as much as possible;
4.1.6
The unit must be fixed before the piping system can be installed.
Remarks:
1. Hydraulic calculation must be carried out after the primary water pipe selection is completed. If
the waterside pipeline resistance is more excellent than the selected pump lift, the larger water
pump must be re-selected, or the water pipe must be increased in size;
2. When multiple units are connected in parallel, the primary and circulating water pumps must be
selected as appropriate according to the hydraulic calculation requirements.
Remarks:
1. The same piping design is allowed to distribute the water evenly.
2. The system must be equipped with an automatic water supply valve, and the highest point of the
water system must be equipped with an automatic pressure relief valve;
3. The drain valve shall be installed at the bottom of the pipeline to facilitate drainage;
4. The pressure relief valve is installed at the highest point of the system pipeline, and the terminal
of the water pipe must have an expansion diameter;
5. Normal working water capacity can ensure normal defrosting in winter (ensure that the water
capacity per kW exceeds 10L);
6. The machine has been equipped with a water flow switch; users do not need to install one more;
