Proline Kryomats

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 (accessories) or connect metal hoses
( 6.3) 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" ( 3).

− 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.
