5 Operation
5.1 General
Personnel Qualifications
The Condair GS humidifier must only be operated by personnel who are adequately qualified, well trained
and are authorized by the customer.
Safety
Observe all safety precautions described in "For Your Safety" on page 7 .
5.2 Operating Procedures
5.2.1 Filling the System
Fill the Condair GS humidifier as follows. The control software also performs the float test to ensure that
the fill system, the water level controls and the drain pump(s) are functioning properly.
1. Close the manual gas shutoff valve in the supply line.
2. Open the shutoff valve in the water supply line.
3. Set the On/Off button on the humidifier to the On position.
The control software then energizes the dual fill valve(s) and starts to fill the tank. When the water
in the float chamber(s) reaches the L1 level (red LED), the control software runs a series of tests on
the fill and drain system as described in "Water Management" on page 13 . On successful completion of
the tests, the float chamber is filled to the L3 level (green LED), and the humidifier goes into standby
mode. This process can take approximately 10-30 minutes depending on the size of the unit.
4. Set the On/Off button to the Off position, and perform the "Ignition Safety Shutoff Test" described below.
5.2.2 Ignition Safety Shutoff Test
Perform the ignition safety shutoff test as described below:
1. Check that the manual gas shutoff valve in the supply line is still closed.
2. Make sure that the contacts of all devices connected to the external security loop are closed.
3. Set the On/Off button to the On position. The control software runs a series of tests on the fill and
drain system, and on successful completion the humidifier goes into standby mode.
4. Set the demand signal to the humidifier from the building management system (BMS) or humidistat
at 100%.
The control software energizes the blower(s) to initiate the combustion sequence. The blower(s) run
at full capacity to purge the system. The control software then verifies the proper functioning of the
safety systems and the blowers as described in "Combustion" on page 12 .
After the safety systems check is completed successfully, the ignition control module(s) is energized.
The spark-igniter(s) attempts to fire up three times to ignite the gas-air mixture. Since the gas supply
is shut off, no flame is detected by the flame sensor(s) and the gas valve(s) is de-energized. The
red LED in the ignition control module(s) flashes to indicate a safety lockout. The warning message
Ignition Fail also appears on the touchscreen display after a short delay.
Note : On units with multiple burners, each burner attempts to ignite in sequence. Hence, it is impor -
tant to wait for all burners to complete its cycle.
The ignition safety shutoff test is successful when no gas flows to the burner(s) when the manual
gas shutoff valve is closed.
