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.
