3.7) SETTING THE PRESSURE CONTROLS
SETTING PRESSURE CONTROLS INSTUCTIONS:
WARNING – The pressure controls must be set while all circuits are live. TO AVOID
ELECTRICAL SHOCK, DO NOT TOUCH the wires or the terminals in which they
connect while setting the pressure controls.
NOTES:
- Setting the pressure controls greatly relies on your ability to tell whether the contactor(s) are
turning the heaters on or off. You should be able to hear the contactor(s), located inside the
Control Box (#1), click on and off. Familiarize yourself with this sound.
- The order in which the pressure controls must be set is the “SAFETY” and then the
“CONTROL”.
- In order to set the “SAFETY” you must keep the “CONTROL” at a higher pressure setting
than the “SAFETY”
- Once the “SAFETY” is set, then you can
lower the “CONTROL” to its correct setting.
- To INCREASE the pressure setting, when
looking down on pressure control, using your
two index fingers, turn the PRESSURE
ADJUSTMENT DIAL CLOCKWISE,
causing the BLACK INDICATOR LINE to
move DOWN the scale.
- To DECREASE the pressure setting, turn the
dial COUNTER CLOCKWISE, causing the
indicator line to move UP the scale.
SETTING INSTRUCTIONS:
1. Open the pressure control covers, as shown on page 12.
2. Adjust the PRESSURE ADJUSTMENT DIAL on the
“CONTROL” so that the BLACK INDICATOR LINE is
somewhere between ½ and ¾ of the way down from the top.
3. Adjust the PRESSURE ADJUSTMENT DIAL on the
“SAFETY” so that the BLACK INDICATOR LINE is
somewhere between ¼ and ½ of the way down from the top.
4. Close the Steam Out (#16) and turn on generator. When the
contactor(s) click on, the pressure will rise. If contactor(s) do not
click on right away, you may need to press SAFETY RESET.
Continue to watch the Pressure Gauge (#15) until you hear the
contactor(s) click off. This may take up to 20 minutes.
WARNING – DO NOT allow the pressure to exceed the rating on the Safety Valve (#18). If
contactor(s) do not turn off before the pressure limit is exceeded, manually shut off
generator, open the Steam Out (#16), and DECREASE the pressure setting on the
“SAFETY” pressure control. Repeat step #4.
