SECTION 3 - OPERATION
Temperature Control
Complete instructions on the programming and operation of the Temperature Controller can
be found in the 9050,9051,9060,9061,9080,9081 Controller manual.
Pressure Control
1. Turn the HIGH PRESSURE LIMIT REGULATOR knob all the way in (clockwise).
2. Turn the PRESSURIZE PUMP switch to the ON position until the desired set point
pressure is reached. Increase the pump pressure by turning the PUMP PRESSURE
ADJUST regulator clockwise, if necessary, to reach the desired pressure. If the cylinder
does not begin to pressurize after a few seconds, it may indicate trapped air in the
cylinder. The trapped air can be removed by loosening the 5/8" hex plug in the top of the
cylinder.
3. Turn the HIGH PRESSURE LIMIT REGULATOR knob out (counterclockwise) until the
pressure begins to drop. The upper limit on pressure has now been set. The pressure will
automatically bleed off when this set point pressure is reached.
4. Open the CYLINDER DRAIN valve to bleed the pressure.
5. Close the CYLINDER DRAIN valve.
6. Turn the PUMP PRESSURE ADJUST regulator out (counterclockwise) as far as it will
go.
7. Turn the PRESSUIZE CYLINDER switch to the ON position.
Caution: Do not set the instrument at a pressure that will allow the water to turn to
8. Open the CYLINDER DRAIN valve to bleed the pressure, if desired.
9. Close the CLINDER DRAIN valve.
steam. A pressure of 1600 psi/11 MPa at a temperature of 600°F/315°C is
adequate to prevent this.
