Connection of external circuits

− 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 circuit is connected to the thermostat, the pump connection
outflow must be closed (use closing plugs) or linked to the return!
− Operate the setting knob only when the bath contents are near the ambient
temperature.
− When no tubing is connected, close the pump connection with closing plugs even
in position .
Operation as circulation thermostat
− Connect 11-12 mm int. dia. tubing (
the pump connector.
− Pump connection outflow always in front, return
connection always at the back.
− Using the setting knob at the pump outflows, divide up
the pump flow in accordance to the thermostating
task.( Section 5.1)
− Position
! maximum flow in the external circuit
(setting knob turned anticlockwise).
− Position
! flow passes through pump outflow and
outlet for bath circulation (setting knob in medium
position).
− Position
! external circuit is closed and the outlet for
bath circulation fully open (setting knob turned
clockwise).
