Conair Thermolator TW-1 User Manual page 47

The TW-1 direct injection and closed circuit models can be
ordered with optional mold purge, which clears the process
lines of fluid using compressed air. The purge is operated by a
manual switch on the left 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.
