MAINTENANCE INSTRUCTIONS FOR
LENNOX HEALTHY CLIMATE HUMIDIFIER MODEL WP2-18
WARNING! 120 VOLTS may cause serious injury from electrical shock. Disconnect
power and shut off water supply before servicing.
1. Note humidistat setting and turn humidistat to the “OFF” position.
2. Disconnect electrical power and turn off water supply.
3. Unlatch humidifier cover assembly (1) from base assembly (2) at the bottom of the cover, lift,
and set aside.
4. Pull out the evaporative assembly (3) by grasping at the top and tipping out.
5. Remove the black distribution tray (4) from the evaporative assembly by unsnapping the white
plastic ends of the Scale Control Insert (7), from the tabs at the end of the tray. Lightly scrape
any calcium deposits out of the “V” notches (5), but do not scrape the granular coating from
the bottom of the tray. This textured surface helps ensure even waterflow for maximum per-
formance. If the granular coating has been removed, place several drops of liquid dish soap
on the distribution tray and clean thoroughly. This will only need to be done once.
6. Slide the evaporative media (6) out from the white plastic Scale Control Insert (7). Clean the
insert frame by twisting and flexing it to loosen the calcium deposits or use a putty knife.
Replace the evaporative media (Part No. 59P94) back into the Scale Control Insert with the
red colored spot up and snap the black distribution tray (4) back into place.
7. Reinstall the evaporative assembly (3) into the base assembly (2). Push the evaporative assembly
(3) in at the top between the retaining ribs that hold the assembly in place in a vertical position.
8. Remove the drain hose (8) from the bottom of the unit. Bend and flex it to loosen the internal
calcium deposits. Then flush it with water under pressure and slip it back onto the drain fitting.
9. Reinstall cover assembly (1) by hooking at the top of base assembly (2) and latching at the bottom.
10. Reconnect electrical power (9) and turn on water supply.
11. Reset the humidistat and check unit operation.
