Removing the Cylinder
1.
Check to see if yellow service light is flashing meaning cylinder replacement is necessary.

Turn OFF the water supply to humidifier.
3.
The old cylinder must be drained completely before removing. This is done by pushing the ON/OFF/Drain
switch to the
“Drain” position.
4.
Let the humidifier drain until no more water is flowing out to drain (usually not more than 10 minutes).
5.
When completely drained, push the ON/OFF/Drain switch to the
“OFF”
position.
6.
Turn OFF all electrical input power to the unit with the external disconnect
. The inside of the humidifier’s
cabinet contains high voltage components and wiring. Access should be limited to authorized personnel.
7.
The power wires to the cylinder are attached by cylinder plugs to the electrode pins on top of the cylinder.
Pull these plugs vertically off the pins.
8.
Using slot screwdriver, loosen the steam hose clamp(s) and pull steam hose off vertically.
9.
Using a small flat screwdriver press the tab on the cable tie holding the cylinder in place and pull the cable
tie open.
10.
Tip the top of the cylinder forward to pivot it and lift the cylinder out.
11.
Always clean the drain valve before installing a new cylinder. Scale from the spent cylinder may have fallen
into the drain valve and could prevent its proper operation.
