Replacing the Canister, 200-460, 380-575

Component Operation and Maintenance

Replacing the Canister

Over a period of operation, the humidifier electrodes become coated with mineral solids. This coating insulates the electrodes and decreases the current flow. To maintain humidifier capacity, the water level slowly rises to expose fresh electrode. Eventually, the entire electrode becomes coated and the water level reaches the top. At this point, the canister full alarm is activated and the output begins to fall. When this happens, it is necessary to replace the full canister.

To replace the canister:

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.

! WARNING

To avoid a shock hazard, all power to the unit must be disconnected before proceeding with the canister replacement procedure.

4.Turn OFF the power at the main unit.

5.Remove the cover from the humidifier cabinet.

! CAUTION

The canister and steam hose may be hot! Allow time for the humidifier to cool before replacing parts.

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 the schematic on the unit. Slide the rubber boot back to expose the connections. Remove the three power wires and the two canister full wires. Do not loosen the screws that secure the electrodes.

7.Loosen the steam outlet hose clamp and slide the steam hose away from the canister top fitting.

8.The canister is now ready to be removed. Pull the canister straight up and out of the cabinet toward you.

9.Replace the canister with the part indicated in Table 20.

Table 20 Humidifier canister part numbers

Part		Capacity
Number	Voltage	lbs/hr (kg/hr)

136798P1	200-460*	11 (5)

136798P2	380-575	11 (5)

* Can operate on 575 V unit with transformer

10. Replace the canister by reversing the above procedure. Make special note of the following:

NOTE

When replacing the canister:

1.Make sure the two “O” rings are lubricated and properly seated on the bottom neck.

2.Always check the fill and drain solenoids for proper operation.

NOTE

When replacing the wiring, connect the red wire from terminal #1 on the interface to the red top terminal on the canister. It is in the middle of a group of three terminals. The black wire from terminal #2 on the interface connects to the power terminal farthest from the red terminal/ wire. The power wire to this terminal is routed through the current sensing coil.
