Please note:
n
Connect the cooling water inlet and outlet according to the labeling on
the device. The inlet and outlet of the cooling water supply may not be
interchanged.
n
The hoses used for the cooling water circuit must be suitable for the
temperature range specified. Also observe the permitted hose diameter.
n
Secure the hose nozzles or the coupling connectors to the hoses using
hose clips.
n
Secure the water cooling 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 or
combustible/non-combustible 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.
