8.3 OPERATION OF MOLD PURGE
A. The mold purge system includes valves and piping that when activated and supplied with
compressed air will expel process water from the mold or process to the central water
return line or drain.
B. Mold Purge is an optional feature and not included on all units. The function of the Mold
Purge requires the purchase on the option.
C. The mold purge feature is used when the pump is turned off and has been cooled
to below 85°F.
E. The operation of the mold purge is as follows (see illustration) :
1. Stop the pump, maintain electrical power to unit.
2. Close the water supply ball valve.
3. Connect a regulated air supply to mold purge compressed air connection.
Note: Air supply should be regulated approximately 10 PSI above drain line
pressure.
4. Mold Purge is activated by selecting the mold purge item from the Utilities menu.
Mold purge is started immediately.
If the pump is running, the follow message will be displayed.
If the pump is not running, the mold purge will start.
5. Press the Stop or Back button to disengage the purge cycle.
6. When water is purged disconnect air supply. The unit can be disconnected at this
time as most of the process fluid should be out of the process lines.
WARNING: Use caution when disconnecting process lines because residual pressure will
remain in the lines. The remaining pressure will be equal to the compressed air pressure
used for the purge process. Use caution because disconnecting process lines under pressure
incorrectly may cause injury.
ALERT: The Purge cycle must be started and stopped. If not stopped, the Purge cycle will
continue and will consume compressed air until stopped.
