in the tank might damage the pump.

The cooling unit should be checked for cooling water every week
and refilled when the flushing pump cannot reach the cooling
water. Remember to add Struers Additive for Cooling Fluid: One
part of Additive for 33 parts of water.
The concentration of additive should always lie between 2.7 and
3.3%; the pH should be around 9. Replace the cooling water if pH

To check the concentration of additive, use a refractometer (0-10
Brix, see diagram.). Concentration = 2 x Brix. Add Struers
Additive for Cooling Fluid if the concentration is lower than 2.7%.
Add water if the concentration is higher than 3.3%.
Important
Always maintain the correct concentration of Struers Additive in the cooling
water (percentage stated on the container of the Additive). Remember to
add Struers Additive each time you refill with water.
