4 Startup Preparations
4-1 Starting the Unit
Unit Start-up (With Autovent Solenoid)
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. 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.
3. 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.
4. Air and Oil will be vented through the Vent Solenoid and into
the reservoir tank.
!
CAUTION
You must purge the system of air before the heating cycle.
Personal injury and system damage can occur from a pressurized system.
5. 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.
6. With 2 minute intervals increase the setpoint to 150 and 200°F.
