8. Commissioning
Risk of electrical shock!
Hazardous high electrical voltage!
Start-up of the unit is restricted to expert staff only (electricians
or expert personnel with equivalent training).
Step 1: Check of mechanical integrity
»
Check cylinder seating.
»
Check steam and condensate hose clamps.
Step 2: Check of electrical wire connections
»
Check that all electrical wire connections (including
steam cylinder wiring) are tight and secure.
Step 3: Switching on the steam humidifier
»
Switch on main breaker.
»
Open water supply stopcock (operating pressure
should be 1bar min., 10bar max./14.5 psi min., 145 psi
max.).
»
Switch on unit by setting control switch to “I”.
Step 4:
The unit performs a self-test
•
If the control includes a display, the message “self-test“
is displayed
For the next steps, control must be set in a way that permanent
steam demand is requested.
Step 5: Normal operation starts
•
the water solenoid valve opens and feeds water into the
steam cylinder
•
Initiation of steam production may take up to 20 mins
»
Let all electrically-driven operations run to completion.
•
As soon as the solenoid valve begins replenishing the
water periodically, the steam humidifier operates at
steady nominal output and the cold start sequence is
completed
Step 6: Monitor unit for leaks
»
Let unit operate for 15 to 30 minutes.
»
If leaks appear, switch off the unit.
Step 7: Repair leaks
»
Repair leaks and check again.
Please note
