►Observe the recommended pressure and pressure differences.
►Always lock out and disconnect the water circuit before working on the product.
►When carrying out maintenance, secure the installation properly by locating and locking out the
pressurized water circuit to prevent it from being re-engaged by accident (LO/TO Lock Out/Tag
Out procedure).
►Regularly check the condition of the pipework and supply circuit connections.
NOTICE
The water cooling circuit may be damaged if an unregulated mains supply is used
Using unregulated mains water can lead to water circuit clogging due to limescale deposition. This
may necessitate complete cleaning and overhaul of the water cooling circuit.
Furthermore, the presence of micro-organisms such as algae and biological substances such
as bacteria can lead to problems in the cooling circuit.
►Connect the water cooling circuit to a regulated water supply.
►Take appropriate measures to prevent the growth of such micro-organisms.
The effect of cooling continuity on the process
If an interruption to the water circuit represents a serious risk for the process, it is advisable
to control the pump cooling with an external system capable of taking over if the water cir-
cuit fails.
To limit corrosion and clogging of the water circuit, we recommend using softened or non-aggres-
sive water with the required characteristics. If the solid pollution characteristics cannot be met, install a
filter on the water inlet.
