Autorefill
(Optional)
An optional autorefill device is designed to maintain the correct level of
cooling fluid in the reservoir. The device consists of a float switch and a
solenoid valve. If the cooling fluid level falls, the float switch will open the
solenoid valve and allow make-up fluid to fill the reservoir. Once the cooling
level reaches the proper level, the float switch will rise and the solenoid valve
will close.
The plumbing connection for the autorefill device, labeled WATER INLET, is
located on the rear of the autorefill assembly. The connection is 3/8 inch OD
stainless steel. Remove the nut and install the tubing from your make-up fluid
source. Reinstall the nut and tubing on to the connection.
Tubing is available from NESLAB. Contact our Sales Department for more
information (see Preface, After-sale Support).
The autorefill device requires its own source of electrical power. The connec-
tor for the line cord (provided with the assembly) is also located on the rear of
the autorefill device. The connector is labelled POWER.
