8. Commissioning
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
»
Open housing cover.
»
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./14.5 psi min., 145 psi
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
•
On completion of the test, the software
version is displayed for a short
moment. Consequently, normal opera-
tion is commenced. However, steam is
not produced without a demand pen-
ding
Step 4: Trigger steam demand
»
Set control to 1-step operation, i.e.
permanent steam demand, and
close safety interlock.
Steam production may show a delay of up to
20 mins.
»
Allow all electrical functions to termi-
nate in their programmed order.
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
»
When everything is o.k., reattach
housing cover
Additional checks:
All electrical functions must be exe-
cutable
