Characteristics
of water cooling
In order to avoid corrosion and clogging of the cooling pipes,
it is recommended to use cooling water with the following
characteristics:
- Treated soft water or non-corrosive industrial water
- pH between 7.5 and 11
- Hardness: < 7 milli-equivalent/l
= 350 mg/l of CaCO

- Solid pollution: < 100 mg/dm

- Solid particle size (maxi): 0.2 mm
- Pressure range: < 7 bars
- Temperature *:
15°C < T < 40°C for ATH 500M
15°C < T < 25°C for ATH 500MT
- Flow rate: 60 l/h
The use of uncontrolled city water can lead to water circuit clogging due
to limestone deposition, which may necessitate in the worst case a complete
cleaning and overhaul of the water circuit.
The presence of micro-organisms like aquatic weed and micro-biological
substances like bacteria can lead to cooling problem in the pump. Appropriate
water treatment system need to be used to prevent growth of such micro-
organisms.
* In case of water temperature is < 20 °C, there is a risk of
condensation.
- Provide a water inlet pipe and
a tap to adjust the flow rate.
- Apply, on the fittings
(supplied by the customer),
Teflon™ tape or glue type
Loctite™ to seal the threads
(connection 1/8 NPT).
- Screw manually the fittings on
the pump.
- Connect the water inlet line
to one of the water fittings
and the other fitting to the
water draining circuit.
- Check there is no leak.
