 The external application must not have a hydraulically blocking effect.
 If cross-sectional area of tube is too low  temperature gradient between bath and external
load due to low flow rate.
 Always ensure the largest possible passages in the external circuit.
 When tightening the union nuts on the pump nipple AF 19, use a wrench AF 14 to counter
the tightening torque (see figure).
 If external control is to be used, provide a Pt100 temperature probe in the external load (
7.5.2 and 7.5.4).
 With loads at a higher position and with stationary pump and ingress of air into the
thermostatic circuit, the external volume can drain away, even with closed circuits  Risk of
thermostat overflowing!
 Secure hoses against slippage with hose clips.
 Unused pump connectors must be closed off.
