3.2 Connecting Cooling Water Piping
Install the cooling water piping as follows:
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.
3. It is recommend 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.
4. Ensure to connect inlet/outlet to the right place. Do not connect them the wrong way
around.
