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.
