8. If any water is present in the system, it must be boiled off before
continuing operation. Select a setpoint of 215ºF (102ºC) and
observe the reservoir tank vent for any signs of escaping steam.
Continue to run at 215ºF (102ºC) until no more steam appears
and pressure has stabilized.
9. When fluid level has stabilized and air and water is purged from
the system, close the Vent Valve. Do not open the Vent Valve
above 250°F.
With the system properly purged, only 4 - 6" of fluid should be
visible in the sight glass. This will allow for expansion of the fluid
as it heats, as well as capacity for process fluid when the pump is
reversed and fluid withdrawn from the mold.
The Model 2016-C is now ready for use. All that is required is to
select a process set point on the controller as described in the
controller manual.
Note: If all traces of water are not removed from the system,
severe cavitation may occur at elevated temperatures.
Indications are a “gravely” sounding pump, fluctuating or
dropping pressure, or rapidly rising fluid level in the
expansion tank. Repeat Step #7 if any of this occurs.
4-2 Shutting Down the Unit
Unit Shut Down (With Autovent Solenoid or Manual Vent Valve)
Cool the unit down by switching the Mode switch to the "Manual
Cool" position. This will disable the heaters (i.e. prevent the
controller from turning them on) and open the cool solenoid, if
equipped with optional heat exchanger. Fluid temperature can be
monitored on the controller display during cool down. When fluid
temperature is below 120ºF, Turn the
Pump Rev|Off|Fwd switch
to Off to turn the unit off.
