3. Maintenance
The machine and the Recirculation Cooling System should be
kept as clean as possible in order to avoid contamination of the
specimens.
Every time water is changed, the cooling tank should be cleaned
carefully to remove all grinding waste. Cleaning will be easier if
Struers plastic inserts are used.
Painted surfaces and keyboard should be cleaned with a moist
cloth and common household detergents.
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.
„
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.
„
Fill the tank with 29.1 l of water and 900 ml Struers Additive.
