coolant in the tank might damage the pump.

Place the pump in the lid.
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.
The cooling unit should be checked for cooling water every week
and refilled when the flushing pump cannot reach the cooling
water. Remember to use Struers Additive (pH should be around
9). Replace if pH is
α 8.0. To check the concentration of Additive
use a refractometer (0-10 Brix, see diagram.). Concentration = 2 x
Brix.
