The humidifier will go into standby mode until the next call for humidity (demand rises above minimum %) at
which time the unit will again begin the combustion sequence.
Taking Out Of Operation
If it is required that the humidifier be taken out of operation (e.g. for service or end of season shut-down),
proceed as follows:
If the unit is firing, remove the demand signal or open the security loop, allowing the burners to shut off and
the blowers to perform a post purge of the heat exchangers before shutting off.
Switch the main power switch from On to Off and then to the Drain position. The drain pump will be
energized and the tank will begin to drain.
Once the tank has completely emptied shut off the drain switch.
Close the shut-off valve in the gas supply line.
Close the shut-off valve in the water supply line.
Isolate the humidifier from the electrical power supply at the main disconnect switch.
