1.PRELIMINARY:

-Pre-start-up checklist completed? yes no

If no, return to Pre-Start-up Checklist before going on with start-up procedure.

2.START-UP PROCEDURE:

The prerequisites for getting power and water into the steam cylinder are as follows:

-check that main breaker is on and power is at the unit.

-check that main water shut-off valve is open.

-on/off/drain switch must be switched on.

-control circuit 8-10 must be made.

-modulation humidistat, if present, must be calling.

-control circuit 82-83 must be made.

-control circuit 84-85 must be made.

-cabinet mounted humidistat, if present, must be calling.

-door interlock switch must be made (interlock switch can be pulled out to operate unit).

The unit will undergo a self-test (P and MC models only) to ensure integrity of all the components:

-Lamp green (observe light energize)

-Lamp yellow (observe light energize)

-Contact relay 1 (24V to 61-20 for rem. yellow)

-Drain (sound and 24 volt at solenoid)

-Fill (24 volt at fill solenoid)

-Contactor (listen to contact pulling in) (Unit must be calling).

-Contact relay 2 (24V to 63-36 for rem. red)

-Contact relay 3 (24V to 61-20 for rem. green)

-Internal test (Test completed)

-Green and yellow blink together to show test passed

It will then start filling the cylinder and begins normal operation. Most water does not contain enough conductivity for full boil on initial start-up. Units will need to concentrate the water over a time period (hours to days). During this process both lights are on.
