from flowing back by using shut-off valves..
In case the system to be cooled is located at a higher level
than the recirculating cooler, prevent the bath liquid from
flowing back when the unit is turned off.
For this purpose, connect electrical solenoid valves or
mechanical shut-off valves to the connectors for feed and
return (12.1. and 12.2.).
The solenoid valve is electrically connected to the
connectors (14.). As soon as the recirculating cooler is
