Replacing the Humidifier Canister

CAUTION
!
Risk of contact with extremely hot surfaces. Can cause injury.
The canister and steam hose may be hot. Allow time for the humidifier to cool before replacing
parts.
The proper procedure to replace the humidifier canister is:
1. Turn off the humidifier by lowering the humidity setpoint below the ambient humidity level.
Record the original setpoint.
2. Place the RUN/DRAIN switch in the DRAIN position to drain the water from the canister.
3. Return the RUN/DRAIN switch to the RUN position after the canister has drained.
4. Turn OFF the power at the main unit electric power disconnect switch.
5. Remove the cover from the humidifier cabinet.
6. Locate the power wires to the steam canister. They are connected to the canister with 1/4" quick
connects. Make note of the wiring configuration before removing any wires. Refer to schematic on
unit. Slide the rubber boot back to expose the connections. Remove the two (2) power wires and
the canister full wire. Do not loosen the screws that secure the electrodes.
7. Loosen the steam outlet hose clamps and slide the steam hose away from the canister fitting.
Release the canister clamp along the base of the canister.
8. Remove the canister.
9. Reverse previous steps to re-assemble humidifier, paying special attention to the following:
• When replacing the wiring, connect the red wire from terminal #1 on the interface to the red tip
terminal on the canister. Reconnect the power wires as before (#2 on the left and #1 on the right).
• When replacing the canister, always check the fill and drain solenoids for proper operation.
