GS Series Installation | 36
Start-Up Procedure
Start-Up Checklist
Before the GS humidifier is operated for the first time, a complete inspection must be performed to ensure
that the installation and all water, gas, steam, electrical and venting connections to the humidifier conform
to the guidelines in this manual. Complete the checklist before commissioning the unit.
Qualified personnel must correct any deficiencies with the installation before commissioning takes place.
Prior to starting the humidifier, it is necessary to ensure that no dirt or dust has accumulated in the
electronics compartment or the burner area. A build up of dust on the electronics can cause overheating
and early failure of the components. If necessary, clean the area around the humidifier to prevent
contaminants from being drawn into the combustion blowers.
Filling The System
Before the GS unit will initiate combustion it must be filled with water and the internal controller must have
completed a self-test to verify that the water fill system, level controller, and drain pump are functioning
correctly.
Close the shut-off valve in the gas supply line.
Figure 29: Plumbing Connections
Remove any demand signal to the unit.
Open the shut-off valve in the water supply line.
Switch the humidifier on.
The fill valve will energize and the tank will begin to fill (fill time is approximately 10 to 30 minutes depending
on unit size). Once the float chamber has registered low water level, the unit will perform an internal test of
the fill and drain system as described in the Water Management section.
At the completion of the test, the float chamber will indicate middle float position (green LED) and the unit
will go into standby mode until a demand signal is received.
Proceed to the safety shut-off test.
