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 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).
