OPERATION

Precautionary Measures

P A G E 12
1 Do not operate the fridge unit without liquid in the bath such that
the cooling coil is covered.
2 Do not operate the fridge unit without the pump unit working to
give good ciculation in the bath as freezing up may occur. While
this will not harm the unit some time may pass before the unit can
be used again. Loss of performance will occur if freezing does
takes place.
3 Do not operate the pump without proper connections both out of
the bath and returning to the bath.
4 Although the practice is not recommended fridge units may
occasionally be subjected to temperatures up to 100°C. This is
provided that they are only being used thus intermittently, for
example for cooling down to temperatures below 40°C.
5 IN NO CIRCUMSTANCES MAY A REFRIGERATED UNIT BE
SUBJECTED TO BATH/LIQUID TEMPERATURES ABOVE
100°C.
6 IF YOUR UNIT SHOULD ICE UP DO NOT TRY TO FORCE THE
PUMP UNIT FROM THE BATH THIS MAY DAMAGE BOTH THE
CHILLER AND THE PUMP. Allow the bath to de-freeze naturally
and then lift the pump from the water. Inspect for damage then
adjust the unit as under Running the Unit.
7 NEVER run the chiller unit without the pump running as this may
result in localised freezing.
