INSTALLING THE HUMIDISTAT
Note: Install the humidistat on the return duct. Never install below humidifier.
1. Refer to the installation manual accompanying the humidistat.
STARTING YOUR HUMIDIFIER
1. Open the water supply valve, put the furnace power back on and start the furnace in a heating cycle. Set the humidistat to the maximum setting. After
a few ON/OFF cycles of the electric valve, you should see water flowing through the drain tube. Check that the water is evenly distributed by the water
diffuser across the pad. Carefully check that both ends of the water supply tube are firmly held in place by their respective compression fitting. Set
the humidistat according to the recommended setting (40-60% RH). Check the system several times to make sure there is a free flow in the drain
tube and there is no leak before leaving the installation unattended. When everything is working fine, affix the nameplate to the humidifier cover.
