− If the cross-section of the tubing is too small ! temperature drop between bath
and external system due to low flow rate. Increase the bath temperature
appropriately.
− Always ensure the maximum possible flow cross-section in the external circuit!
− When the external consumer is placed at a higher level than the thermostat, the
pump is stopped and air penetrates into the thermostating circuit the external
liquid may drain down into the bath even with a closed system ! danger of
flooding the thermostat!
− Protect tubing with hose clips against slipping off!
− When no external consumer is connected to the thermostat, the pump outflow
connection must be closed (use closing plugs) or linked to the return!
b) Bath/Circulation thermostat
− Connect 11-12 mm int. dia tubing (
pump connector
− Pump outflow always in front, return connection always
