Manufacturers of air-cooled chillers, freezers, and ice water machines

1、 Installation Program

During installation, please check if the machine is damaged and choose a suitable location for installation and future maintenance.

2. The site for installing the unit must be a floor, installation pad or foundation with a levelness within 6.4mm, and able to withstand the operating weight of the unit.

3. The unit should be placed in a room temperature of 4.4-43.3 ℃, and there should be sufficient space around and above the unit for daily maintenance work.

4. A space for cleaning the condenser tube bundle should be left at one end of the unit, and door openings or other suitable openings can also be used.

5. Choose water pipes of appropriate diameter, and connect the cooling system and cold water system correctly when the unit is operating at maximum power.

For ordinary applications, the water flow velocity through the evaporator and condenser is allowed to be between 1.0-3.6m/s.

7. Under any load conditions, the water flow rate should remain stable.

8. The design and installation of all chilled water and cooling water pipelines should be carried out according to conventional methods, and the chilled water pump should be located on the inlet pipe of the unit to ensure positive pressure and flow inside the unit. Vibration reduction pipes should be installed during piping to ensure appropriate elasticity, and to prevent the water in the evaporator from being discharged when the water pump stops.

9. The pipeline should have a sturdy support independent of the chiller unit to avoid stress on the components of the chiller unit. The installation of hangers should facilitate the alignment of pipelines.

To reduce noise and vibration, it is best to install vibration isolators on pipelines.

11. In order to use the chiller unit economically and effectively, it is recommended to ask a water treatment expert to analyze the water quality of the evaporator and condenser. Poor water quality can cause scale buildup, affect heat transfer, or produce corrosion and sedimentation, breed organic matter, affect the performance of the unit, and increase operation and maintenance costs.

Generally speaking, proper water treatment and regular cleaning of the tube bundle can maintain its good performance. If the existing water quality conditions cannot be improved by appropriate methods, it is necessary to consider allowing the tube bundle to have a large fouling coefficient or specifying specialized structural materials.

13. Please install a filter at the inlet of the water pipe and clean it regularly.

After the leak test is completed, all connecting ports must undergo rust prevention treatment.

15. For the convenience of daily maintenance work, users can take some (or all) of the following measures: a) Pressure gauges and shut-off valves with plugs can be installed on the inlet and outlet pipelines of cooling water and chilled water, as close as possible to the chiller unit; b) Hanging rails and crossbeams can be installed above the equipment for easy maintenance.

Operation sequence:

Firstly, turn on the main power switch to the ON position;

2. Turn on the switches of the cooling water tower and cooling water pump. At this time, be sure to open the inlet and outlet valves of the cooling water (note: air-cooled models do not require a cooling water tower)

3. Turn on the operation switch of the freezer again, and the chilled water pump will start running. Please note that the inlet and outlet valves of the chilled water must be opened. After a delay switch, the compressor will automatically operate. Please check and adjust the required temperature.

4. When shutting down, please operate the shutdown in reverse order
