Please note:
Connect the cooling water inlet and outlet according to the labeling on
n
the device. The inlet and outlet of the cooling water supply may not be
interchanged.
The hoses used for the cooling water circuit must be suitable for the
n
temperature range specified. Also observe the permitted hose diameter.
Secure the hose nozzles or the coupling connectors to the hoses using
n
hose clips.
Secure the water cooling return hose in the outlet area to prevent the
n
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.
Avoid kinking or crushing the hoses.
n
We recommend using a leakage water detector with water shut-off
n
function to prevent leakages from causing damage in the cooling water
system.
Only use cooling water that meets the quality requirements.
n
If the condenser leaks, there is a danger that refrigerating machine oil or
n
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.
