6.5 Connecting external loads
Operation as circulating thermostat

When used as circulation thermostat, care for shortest
hose connections with largest inner diameter as possible.
This gives the best flow.
 Push hose with 11
—
12 mm internal width onto 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”.


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 thermo-
static circuit, the external volume can drain away, even with closed circuits

Risk of ther-
mostat overflowing!

Secure hoses against slippage with hose clips!

Unused pump connectors must be closed off.
Bursting of the external consumer due to overpressure
Scalding, frostbite, cutting

Use a pressure relief device on pressure-sensitive consumers (e.g. glass reactors).
