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 1-2 must be made.

–modulation 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 to ensure integrity of all the components:

–NHTC Start-Up Unit Cylinder

–Reading Cylinder Data

–Inlet Valve

–Drain Valve

–Heat Controller

–Pump

–Bleed Valve

–Steam Relay

–Service Relay

–Error Relay

–Operation Relay

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).
