JULABO LH 85 High Dynamic Temperature System - Manual (Page 28)

Preparations

Notice:
If an expansion vessel is not used, make sure the connector (16) is closed with a cap
nut.
If an external expansion vessel is mounted later, a part of the bath liquid should be
drained before (see chapter Emptying on page 32). It might be helpful to put the
castors at the back on a base which is approximately 10-15 mm high. So the bath
fluid can be collected in the front part of the internal reservoir.
Warning:
An external expansion vessel is heated up by the wam outgoing air, especially in
small rooms or if there is not enough distance between the wall and the unit.
In this case only bath liquids with a fire point of
100 °C are allowed to be used.
5.5. Cooling water connection
Notice: Cooling water circuit
Risk of oil leaking from the refrigeration system (compressor) of the recirculating
cooler into the cooling water in case of a fault in the cooling water circuit!
Observe the laws and regulations of the water distribution company valid in the
location where the unit is operated.
Even high quality heat exchangers as they are installed in our
equipment can be damaged by unsuitable cooling water.
The quality of the cooling water depends on the local conditions.
The heat exchanger may become leaky due to corrosion or it may
become clogged due to particulate matter
Caution:
Securely attach all tubing to prevent slipping.

Example:
PVC-tubing
If water-cooling is used to cool the system:
 Supply cooling water via the inlet (18).
 Conduct the cooling water via the outlet (17) in the
respective sink or return flow circuit.
