 Connect the tubing for cooling the external
system to the pump connectors (22, 23) for
feed and return on the rear of the recirculating
cooler.
 In case the system to be cooled is located at
a higher level than the recirculating cooler,
take note of bath liquid flowing back when the
unit is switched off. Should the filling volume
of the bath tank not be sufficient, prevent the
liquid from flowing back by using shut-off
valves.
Flood hazard!
For this reason, solenoid valves for loop
circuit or shut-off valves can be integrated in
the loop circuit.
