Water cooling connection
Characteristics
of water cooling
In order to limit the 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/dm
3
(28 mg CaO or 50 mg CaCO
3
per liter water) = 3.5 mmol/l
(100 mg CaCO
3
per liter water)
- Resistivity: 20000 .cm > R > 1500 .cm
- Solid pollution < 100 mg/dm
3
- Solid particle size (maxi): 0.2 mm
- Pressure range between 200 and 700 KPa
- Temperature:
15 °C < T < 25 °C MT model
15 °C < T < 40 °C M model
- Flow rate: 60 l/h
- Deionized water compatible

In case of water temperature is < 20 °C, there is a risk of condensation.
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 cooling 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.
- Provide a water inlet pipe and a tap to adjust the flow rate.
- Connect the water inlet line to one of the cooler water fittings
1/4 NPT female on the pump, with the other fitting connected to
the water draining circuit via a tube (supplied by customer).
Water leak risk : maintain the water valve inlet fitting with a flat
wrench (13 mm) during the water line connection (pipe equipped with
connector), this to avoid valve damage.
Do not mount water fittings above electrical components in case of leak
at water fitting connection.
