Connect the cooling water hoses.
The hose connections may be unscrewed and removed to make use of the integrated G
1/8" threads.
Ensure that the water supply is constant and within the quality, temperature and flow
rate limits specified in
NOTICE:
In the event of coolant failure, the pump must be allowed to cool down to ambient
temperature before restartings.
NOTICE:
Condensation may occur if a water cooling block is used in high humidity
environments. Protect the pump and other equipment by considering the design of
the installation.
Pipes in the water cooling circuit may become blocked if the cooling water contains too
much calcium carbonate or if it contains particles that are too large. Corrosion of the
water cooling circuit may occur if there is too little calcium carbonate and oxygen in the
water. Good quality drinking water is usually suitable. If in doubt, check the quality of
the cooling water supply and, if necessary, provide treatment and filtration.
Either of the two push fit connectors on the water cooler can be used for the water
supply or return connections.
