Read the instructions below to avoid damage to the user, the environment and the machine itself
before using the high-pressure cooling pump.
This high-pressure cooling pump generates high pressures and therefore can unauthorized use
result in serious injuries. For your own safety and for the safety of others, the following rules must
always be observed:
• Do not use the high-pressure cooling pump in case of any sign of damage to the electrical sys-
tem or pump parts.
• The high-pressure cooling pump is designed especially for use with FlexClamp nozzles for
cooling and spraying with water and should be used for this purpose only.
• The high-pressure pump is designed to work with clean water of drinking water quality in suffi-
cient quantities.
3.1 Water supply
The water supply tap must be a ball plug valve to avoid unnecessary pressure drop.
The water supply to the cooling pump requires a 3/4" pipe and a minimum pressure of 2 bar at maximum con-
sumption. If no manometer has been installed, the water capacity can be checked by removing the hose after
the filters. If approx 30 l/min. can be drained, the water pressure is OK.
If the water supply pressure is too low, you can install an auxiliary pump in front of the pump on the water supply
piping. Contact the local plumber.
In some areas, a supplementary vacuum valve may be required in front of a chemical filter. Contact the lo-
cal plumber. (Not supplied by SKOV A/S).
Quality requirements for drinking water
Where not otherwise indicated, the tables list the maximum permissible values.

Remarks
Temperature °C It should be ensured that the water is max.
20ºC at the water tap.
pH
7 – 8.5
The water must not be calcium agressive
Calcium (Ca) mg/L

The content should not exceed 200mg/l
Magnesium (Mg) mg/L
50
Calcium content, total dH
5 – 30
The calcium content of the water should
range from 5 to 30 dH
Sodium (Na) mg/L

Total phosphorous con-
tent (P) mg/L

Cl mg/L The content should be kept to a minimum;
at the same time comply with the microbio-
logical requirements
If the water does not comply with the above requirements, take preventive measures to reduce calcium such as
applying electronic calcium decomposer or point-of-entry treatment.
If the water contains brass-corrosive substances, use stainless steel nozzles instead.
