4-3 Returning Fluid to the Tank
Returning Fluid to Tank (With Autovent Solenoid)
If the unit is to be moved from one process to another (i.e. mold
changes, etc.), the following steps must be taken to drain the mold
and process lines. Note that this is just the opposite of unit start
up/air purge:
1. Cool fluid to 100 degrees °F maximum.
2. Turn the Pump Rev|Off|Fwd switch to Off.
3. Turn the Pump Rev|Off|Fwd switch to Rev. The pump
will then run in reverse, drawing fluid from the mold and
lines, and into the reservoir tank.
4. Watch the sight glass to prevent overflow of the
reservoir tank.
!
CAUTION
The reservoir tank may not have adequate volume
to contain the total system capacity of fluid.
An overflowing reservoir allows hot fluid to escape
and become a potential fire and slip hazard.
The total capacity of the tank is 7 gallons (26.5 liters).
If it appears that the tank may overfill, connect a line from the
FILL port of the reservoir tank to a clean auxiliary container.
