Component Operation and Maintenance

6.5Humidifier

6.5.1Infrared Humidifier

During normal humidifier operation, deposits of mineral solids will collect in the humidifier pan. This should be cleaned out periodically to ensure efficient operation. Each water supply has different char- acteristics, so the time interval between cleanings must be determined locally. A monthly check (and cleaning if necessary) is recommended.

Removing the Pan

To remove humidifier pan, first open disconnect switch and open front panel. Allow time for pan and water to cool. Unlatch front retainer clip (or remove screw from bracket on some units). Pull pan for- ward. Remove stand pipe to allow pan to drain. Disconnect drain line. Pull pan forward to remove it.

! CAUTION

Before removing pan, be sure power to unit is disconnected and water in the humidifier pan is no hotter than lukewarm.

Cleaning the Pan

An autoflush system can greatly increase the time between cleanings but does not eliminate the need for periodic checks and maintenance.

Scale on the side and bottom can be loosened with a stiff brush. Flush with water and replace pan in humidifier.

Changing Humidifier Lamps

1.Open disconnect switch.

2.Open front panel.

3.Remove screws securing line voltage compartment cover, then remove the cover.

4.In line voltage compartment, disconnect one end of the purple jumpers, then locate the burned out bulb with a continuity meter.

5.Remove humidifier pan. Refer to Removing the Pan on page 53.

6.Remove lamp brackets (2) under lamps.

7.Loosen two screws securing bulb wires to junction block.

8.Pull bulb straight down.

9.Replace bulb. Wrap wires once loosely around bulb. This will support the bulb and also allow for thermal expansion. Make sure lamp wires are secure in the junction block.

! CAUTION

Do not touch the quartz lamps with your bare hands. Oily deposits such as fingerprints will severely shorten bulb life. Use clean cotton gloves at all times.

10. Reverse Steps 1 through 6 to reassemble.
