Instruction Manual
5. Maintenance
Clean all accessible surfaces with a moist cloth.
Remove the grinding/polishing disc and remove all dirt from the
tray and the drain tube.
Only relevant when a Recirculation Cooling Unit is connected:
Replace the cooling water in the Recirculation Cooling Unit at
least once a month.
Place a Disposable Plastic Container (TREPO) in the tank
and fold it over the edge.
Fill the tank with 30 l of water. NB! Too high a level of
coolant in the tank might damage the pump.
Add Struers Additive according to the instructions.
Put the lid on the tank.
Place the pump in the lid.
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.
