2.) OPERATION & SEQUENCE OF EVENTS
IMPORTANT – READ INSTALLATION INSTRUCTIONS BEFORE OPERATING
1. Turn on water supply from the source to the Generator.
2. OPEN all valves on the Generator except for the Manual Drain (#19).
3. Place main disconnect switch in ON position.
4. Place ON/OFF Switch (#2) in ON position.
• The Water Solenoid (#7) [and Pump (#8), if high pressure] will engage and the
chamber will begin to fill with water. As the water level rises, it will make contact
with the (G OR D) and (A) probes, indicating the heaters are safely submerged. At
this time the contactor(s) will engage, supplying power to the heaters, causing
steam pressure to accumulate.
• The chamber will continue to fill with water until 1 second after the water makes
contact with the (C) probe, causing the Water Solenoid (#7) [and Pump (#8), if
high pressure] to turn off.
• If the contactor(s) still have not engaged at this time, you may need to press the
Safety Reset (#13) on the “Safety” Pressure Control (#12). If your generator is
equipped with a Manual Low-Water Reset (MLWR) (#3), it must be pressed at
this time to engage the contactor(s). If your generator is equipped with a Motorized
Auto-Flush & Drain (MAFD) (#20), you must wait until it closes before the
contactor(s) will engage. (approximately 3 minutes)
• Steam pressure will continue to rise until is reaches its set operating pressure. This
may take up to 25 minutes. At this time, the “Control” Pressure Control (#12)
will cause the contactor(s) to disengage. The pressure will drop approximately 2-8
PSI until the “Control” Pressure Control (#12) causes the contactor(s) to
reengage, causing the pressure to rise again. The contactor(s) will continue to cycle
on and off during operation.
5. The Generator is now fully operational and will produce steam until it is turned off.
• As steam is exhausted, the water level will drop until 3 seconds after it breaks
contact with the (C) probe. At this time, the Water Solenoid (#7) [and Pump (#8),
if high pressure] will engage and the chamber will again fill with water. The
chamber will continue filling until 1 second after the water makes contact with the
(C) probe. The Water Solenoid (#7) [and Pump (#8), if high pressure] will
continue to cycle on and off during operation.
6. To shut off the Generator, place ON/OFF Switch (#2) in OFF position. Pressure will
drop naturally as the chamber cools, or the Generator may be drained manually through
Manual Drain (#19). (See Manual Blow Down 3.1)
WARNING – HOT WATER and STEAM under HIGH PRESSURE can lift drain pipes
right off the ground and cause SERIOUS INJURY. Make sure drain pipe is SECURE
and CANNOT move. The drain must be directed into a HIGH TEMPERATURE drain
(NO PVC) or outside.
