7. 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 until no more steam appears and
pressure has stabilized.
8. When fluid level has stabilized and air and water is purged from
the system, allow the vent timer to run out.
Unit Start-up (With Manual Vent Valve)
The highly engineered controls and controller make this unit
almost self operating. Before you can begin heating, it will be
necessary to perform the following start up procedures. This will
ensure that all air is vented from the system to prevent fluid
degradation and damage to the heater.
1. Add fluid to the reservoir tank until the level is near the top of
the sight glass.
2. Open the Vent Valve on the back of the unit.
3. Turn the Pump Rev|Off|Fwd switch to Fwd to start the pump.
Check motor rotation by observing the pressure gauge. If the
gauge indicates positive pressure, rotation is correct. If not,
disconnect power and reverse the incoming power leads.
4. As fluid is drawn out of the reservoir tank to fill the process, the
fluid level will fall in the tank. Continue to add fluid to
maintain the level about 4 inches from the bottom of the sight
glass.
!
CAUTION
You must purge the system of air before the heating cycle.
Personal injury and system damage can occur from a pressurized system.
5. Air and Oil will be vented through the Vent Valve and into the
reservoir tank.
6. Two minutes after the unit has built at least 5psi of pressure,
select a set point of 100°F and switch unit into the "Auto" mode.
As the oil warms up, viscosity will decrease, and the pressure
will fall.
7. With 2 minute intervals, increase the setpoint to 150 and 200 °F.
