.2 Connecting Cooling Water Piping
Install the cooling water piping as follows:
Install the cooling water piping as follows:
1. Cooling water inlet/outlet connector : Rc3/8 female.
1. Cooling water inlet/outlet connector : Rc3/8 female.
2. Water pipes can be vinyl hoses or copper pipes as long as the withstanding pressure of those
is 1.5 times higher than cooling water supply pressure.

is 1.5 times higher than cooling water supply pressure.
3. It is recommended that a filter is installed in the water line between the cooling water main
valve and the compressor unit to prevent water scales. It is also recommended to install a
flow meter (approx.0
~
15L/min.) between the filter and the compressor unit to check the flow
rate.

1. Determine the cooling water flow rate within the allowable range as shown in Fig. 3-2.
Always use the proper cooling water that meets the requirement. Keep the cooling water
supply pressure less than 0.7MPaG.

・
If the temperature of cooling water is below 5°C, it can cause overloading or a difficulty in
starting the compressor.
・
If the temperature of cooling water is below 5°C, it can cause overloading or a difficulty in
starting the compressor.
・
If the temperature of cooling water is higher than 32°C, the thermal switch will be activated
due to the overheat and turn off the compressor.

If the temperature of cooling water is higher than 32°C, the thermal switch will be activated
due to the overheat and turn off the compressor.
・
Excessive flow rate shorten the lifetime of heat exchanger.

Excessive flow rate shorten the lifetime of heat exchanger.
2. For the standard quality of cooling water, we refer to the water quality control standard set by
The Japan Refrigeration and Air Conditioning Industry Association.
