Instruction Manual

4. Maintenance

Empty and clean the sieve in the Recirculation Cooling Unit.
Refill the Recirculation Cooling Unit.
Always use the correct concentration of Struers Additive in the cooling water
(percentage stated on the container of the Additive). Remember to top up
with Struers Additive each time you refill with water.
AbraPlan-10 and the Recirculation Cooling Unit should be
cleaned regularly, in order to avoid damaging effects to the
machine and the specimens from abrasive grains or metal
particles.
When cleaning AbraPlan-10:
Detach the cover over the grinding stone and remove any
material that may have accumulated on the bottom of the
drain pan.
The cooling unit should be checked for cooling water after 8 hours
use or at least every week. The unit must be refilled if the
flushing pump cannot reach the cooling water or if the cooling
water is too contaminated. Remember to add Struers Additive for
Cooling Fluid: One part of Additive for 33 parts of water.
To check the concentration of additive, use a refractometer.
Concentration = Brix value. The concentration of additive should
always lie between 2.7 and 3.3 %. Add Struers Additive for
Cooling Fluid if the concentration is too low.
When cleaning the Recirculation Cooling Unit empty the tank of
cooling water and clean the tank and the sedimentation container
mounted under the discharge branch.
Replace the cooling water in the Recirculation Cooling Unit at
least once a month.
Place a disposable plastic insert (TREPO) in the tank and fold
it over the edge.
Too high a level of coolant in the tank might damage the pump.
Fill the tank with 29.1 l of water and 900 ml Struers Additive.
