PERATION
TW-1 and TW-2 direct injection and closed circuit models can
be ordered with an optional purge valve, which clears the
process lines of fluid using compressed air. The valve is oper-
ated by a manual purge switch on the side of the unit.
IMPORTANT:
Before purging the process lines, be sure
that the cooling water source feed is closed. If the feed is
open and the air line has a higher pressure than the cooling
water, air may be injected into the cooling water system. If
the cooling water pressure is higher than the air line, cooling
water may be injected into the air line.
Press to shut down the Thermolator.
◆
The RUN/STOP LED turns red.
Turn off the cooling water supply to the unit.
Press and hold the manual purge switch to start

◆
The Purge Valve LED lights.
◆

◆
The STOP and RUN buttons are deactivated during the
purge or when the cool delay off timer is active.
The time required to clear the process lines of fluid will
vary according to the length of the process piping and the
size of the tooling.
Release the purge switch to stop purging.
