Page: 28 / 100

Note the following:
n
Secure the cooling water hoses in place on the device using hose clips.
n
Secure the cooling water return hose in the outlet area to prevent the
hose from jerking suddenly, even when pressure surges occur.
Secure the water cooling return hose in the outlet area in such a way
that hot cooling water cannot spray out.
n
Avoid kinking or crushing the hoses.
n
We recommend using a leakage water detector with water shut-off
function to prevent leakages from causing damage in the cooling water
system.
n
Only use cooling water that meets the quality requirements.
n
If the condenser leaks, there is a danger that refrigerating machine oil
and refrigerant from the device’s refrigerant circuit will mix with the
cooling water. Observe the legal requirements and provisions of the
water supply company applicable at the operation site.
