Place a pail underneath the drain plug located on the bottom of the humidifier cabinet. Lift the tab on the drain plug and remove the plug. Allow all water to drain from the unit. See Fig. 15. Remove the front door from the humidifier. Rotate the latches one-half turn, then pull the door forward. See Fig. 9. Remove and inspect the evaporator pad assembly. Lift the bearing from its retainer. See Fig. 12. Pull the assembly away from the motor to disengage the assembly shaft from the motor coupling. Rotate the evaporator pad assembly 90 degrees and remove it through the access opening. See Fig. 13. Inspect the evaporator pad. If the pad is heavily loaded with scale, replace the pad. To replace the pad, pull or cut the old pad from its frame. Pull the new evaporator pad onto the support frame until the pad is located between the ends of the drum. NOTE: For best performance, the evaporator pad should be replaced before each heating season. 6. Inspect the float assembly. Remove the float arm from the valve body by sliding out the pin and lifting off the float arm. See Fig. 14. Inspect the rubber valve seat located inside the float arm. If the seat appears to be nicked or worn, invert the seat or replace it with the spare valve seat located on the float arm. Inspect the water opening in the valve body. If the opening is clogged, use a pin to remove the obstruction. Remove any accumulated deposits from the valve body and float arm. 2. 3. 4. 5. 4 7. Clean the water pan and unit cabinet.

Do not force or bend the pin. The float arm should have free up-and-down movement. Install the evaporator pad • If water drips from the humidifier, check the drain hose for kinks or obstructions. If your unit is a Model 49WS, dripping may indicate that the float valve needs adjustment. If your humidifier fails to operate properly, contact your servicing dealer for troubleshooting and repairs. State the model and serial numbers of your equipment (these numbers should be recorded on page 6 of this booklet.) Specify the apparent problem.

Refer to startup procedures listed on pages 2 and 3. BEFORE YOU REQUEST A “SERVICE CALL” BEFORE YOU CALL FOR SERVICE, CHECK FOR THESE EASILY SOLVED PROBLEMS: • Check the main power disconnect switch. Verify that the circuit breakers are ON or that fuses have not blown. If you must reset breakers or replace fuses, do so only once. Contact your servicing dealer for assistance if the breakers trip or the fuses blow a second time. • If the humidity level is too low, check the humidistat setting. Check that the saddle valve is turned ON. Check the evaporator pad, and clean or replace the pad as necessary. Check water level in 49WS. • Check for sufficient airflow. Check the furnace filter or electronic air cleaner for excessive accumulations of dirt. Check for blocked return- or supply-air grilles. Be sure grilles are open and unobstructed.
