Your humidifier will maintain its efficiency for a long

period of time. If it is not serviced, damage may

result. Service it every mointh. Follow instructions

below. Since water conditions vary, it may be nec

essary to service either more or less often.

Establish your own servicing schedule.

REGULAR MAINTENANCE

1. Turn off electricity at the fuse box.

2. Disconnect the water supply tubing at the quick

disconnect. The water will automatically shut off.

3. Remove the drain line {if used) and catch any

water with a pail.

4. Front Service (preferred):

Remove the front panel, disengage the media

motor electrical disconnect, remove the overflow

tubing, slide out the reservoir and media wheel

assembly.

5. Bottom Service (only if insufficient space in

front):

Remove the front panel, disengage the media

motor electrical disconnect, remove the overflow

tubing, remove the lower rod screw, unlatch and

remove the lower case and slide out the reservoir

and media wheel assembly.

Use care when removing either the reservoir

assembly or the lower case and reservoir assem

bly since the reservoir is filled with water.

6. Remove the media motor and panel assembly by

releasing the clip and sliding the assembly

upward from the reservoir divider. Slide the

reservoir divider upward from the reservoir and

remove.

7. Empty the water from the reservoir.

8. Rinse and clean the reservoir, media, media

wheel, and reservoir divider after removing any

lime buildup. Detergent such as vinegar or Sears

All-Purpose Humidifier Cleaner (Stock No. 42

14713) may be used to loosen lime deposits.

NOTE: To aid in future cleaning, an optional

accessory Reservoir Liner may be purchased

through the Sears Parts Department; call 1-800-

4-MY-HOME to order Part No. 215682-01 (see

Exploded View, Page 17). The liner may be flexed

to aid in loosening accumulated lime buildup.

CAUTION: Do not put parts in a dishwashing

machine. The high temperature in the washer may

damage parts. Handle all parts carefully. Be careful

that no water or cleaner enters the motor or electrical

parts.

9. Deposits will form on the media pad. Unless the

deposits are light and the pad can be cleaned, it

must be replaced. Replacement pads are avail

able from Sears (Stock No. 42-9336).

10. If the reservoir has been overflowing, the float

valve button may be worn. In normal operation,

this button will eventually erode much like a

faucet washer. Remove the float valve button,

turn it over, and reinsert. Replacement buttons

are available by calling the Sears Parts

Department; call 1-800-4-MY-HOME.

11. Reassemble the media pad in the media wheel.

Replace the reservoir, divider, media wheel, media

motor, and panel assembly. Engage panel clip.

12. Reassemble humidifier in the following manner:

A. Front Service:

Slide the reservoir and media wheel assembly

into the humidifier, engage the media motor

electrical disconnect, attach the overflow

tubing, connect the water supply tubing.

B. Bottom Service:

Slide the reservoir assembly into the lower

case, attach the lower case assembly to the

humidifier (make certain side latches are

secured), engage the media motor electrical

disconnect, attach the overflow tubing and

water supply tubing. Reinstall lower rod screw.

13. Connect the water supply tubing at the quick

disconnect and allow the reservoir to fill. Check

the water level, adjust the float if required, and

reinstall the front cover.

14. Turn on the electricity at the fuse box, push the

humidifier switch to “ON” and turn the humidis-

tat to the “TEST” position to check the humidifier

operation. The furnace may have to be running

for the humidifier to operate, depending on elec

trical connection. Set the humidistat according

to the outdoor temperature as instructed on

label.

CAUTION: Do not leave in “TEST” position.
