8. Commissioning
The descriptions given hereafter particularly
relate to the usage of a kit with the Control
Standard.
Risk of operating error!
Start-up of the unit is restricted to expert staff
only (electricians or expert personnel with
equivalent training).
Step 1: Check of mechanical integrity and
wiring
» Check cylinder seating.
» Check steam, condensate and
drainhose clamps.
» Check that all electrical wire connec-
tions (including steam cylinder wir-
ing) are tight and secure.
Step 2: Switching on the steam humidifier
» Switch on main breaker.
» Open water supply stopcock (opera-
ting pressure should be 1bar min.,
10bar max.).
» Switch on unit by setting control
switch to “I”.
Step 3: The unit performs a self-test and,
then, commences normal operation
• During self-test, the display flashes for
a couple of seconds (only with Control
Standard)
• On completion of the test, the software
version is displayed for a short moment
(only with Control Standard). Conse-
quently, normal operation is commen-
ced. However, steam is not produced
Step 4: Trigger steam demand
» Set control to 1-step operation, i.e.
permanent steam demand, and
close safety interlock.
• The water inlet solenoid valve opens
and feeds water into the steam cylin-
der
Step 5: Monitor unit function and check
for leakage
» Let unit operate for 15 to 30 minutes.
» If leaks appear, switch off the unit.
Risk of electrical shock!
Hazardous electrical voltage!
Follow safety instructions for work on live
components.
Step 6: Repair leaks
» Find leaks and eliminate.
» Check again for leaks.
