Commissioning and notes on operation
Caution!
Before the Condair GS...OC is operated for the first time, the responsible per
sonnel must
inspect all installations for correct execution
and check that the
unit is
correctly configured (see check list in chapter 6)
. All deficiencies must be corrected
by specialist action before commissioning takes place.
The humidifier is operated as follows:
•
Examine the humidifier and all installations for possible damage
.
Caution!
Damaged units and units with damaged installations must not be operated.
•
Check the cleanliness of the outer cabinet
:
The panels may be cleaned with a damp cloth and warm soapy water.
Caution! Make sure no water is dripping into the cabinet through the ventilation openings in
panels of the unit housing.
•
Fill the water tank
:
• Close the shutoff valve in the gas supply line.
• Open the shutoff valve in the water supply pipe.
• Set
the internal or
the external regulator to maximum humidity demand.
• Switchon the service switch in the electrical supply circuit.
• Switchon the humidifier at the unit switch.
• The filling valve opens and the water tank fills (filling time: approx. 30 minutes for the largest
model, for smaller units the filling time is shorter). At the end of the filling cycle the control unit
checks the function of the water level unit. If the control unit has verified the proper function of
the water level unit the ignition sequence starts. After three attempts at ignition the auto ignition
switches off. The red LED lights and a corresponding error message is shown in the display. Now
switch the humidifier Off.
•
Check ignition safety switch-off
:
The regulator is still set to maximum humidity demand and the shutoff valve in the gas line is closed.
• SwitchOn the humidifier at the unit switch.
The combustion air blower(s) start(s). Note: On multiblower units, wait until all blowers have
started.
Then, 15 seconds later (prepurging time) the igniter is activated and the gas pressure regulat
ing valve opens. After 7 seconds the gas pressure regulating valve closes and the igniter is de
energized (due to missing ignition).
Note: On multiburner units, this process is successively completed for all burners.
After three ignition attempts per burner (complete with prepurging), the humidifier goes into
safety lockout.
• Open the shutoff valve in the gas supply pipe.
No gas should flow to the main burner. End of the test.
• Switchoff the humidifier at the unit switch. Note: To reset the safety switchoff, switchoff the
humidifier for at least five seconds and then switch it on again.
• Adjust the
humidity
controller again to the set humidity value.
