Operation as circulating thermostat

YACE0099 / 10/9/2018
Bursting of the external consumer due to overpressure
Scalding, frostbite, cutting

Use a pressure relief device on pressure-sensitive
consumers (e.g. glass reactors).
 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!
 If external control is to be used, provide a Pt100 probe in the external load
( Section 7.7.2 and 7.7.4).
 When tightening the union nuts on the pump nipple AF 19, use a wrench AF 14
to counter the tightening torque (see figure).
 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.
 When used as circulation thermostat, care for
shortest hose connections with largest inner di-
ameter as possible. This gives the best flow.
 Push hose with 11
hose olive or connect metal hoses
( 6.4) to pump connectors.
 Pump connectors at side:
Inlet and outflow  see labeling housing.
 Pump connectors at back
Inlet and outflow  see labeling housing.
 Set bypass valve to "external".
