Returning Fluid To Tank (With Manual Vent Valve)

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. Open the Vent Valve to allow in fresh air into the pipes.


3. Turn the

Pump Rev|Off|Fwd

switch

to Off.

4. 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.

5. Watch the sight glass to prevent overflow of the

reservoir tank.

If it appears that the tank may overfill, connect a line from the

FILL

port of the reservoir tank to a clean auxiliary container.
