Changing Humidifier Lamps, Autoflush Operation

Component Operation and Maintenance, Checks and Adjustments

Changing Humidifier Lamps

1.Open disconnect switch.

2.Open middle 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.

6.Remove lamp brackets (3) under lamps.

! 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.

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 junction block.

10.Reverse steps 1-6 to reassemble.

Autoflush Infrared Humidifier Cleaning System

NOTE

To operate properly, the Autoflush Humidifier requires a water source that can deliver at least 1 gpm (0.063 l/s) with a minimum pressure of 20 psig (138 kPa).

The autoflush system will periodically flush the humidifier pan with water to prevent the buildup of water minerals due to saturation. Because water conditions vary, the amount of water flushing through the system may be programmed to match local needs.

Water amounts between 110% and 500% of the amount needed for humidification may be selected. Operation of the flushing system is then automatic and no further adjustments need to be made.

Autoflush Operation

The operation of the autoflush is divided into four steps beginning with a call for humidification.

1.If the humidifier has not been activated for over 30 hours, the autoflush will flow water into the pan for about 30 or 60 seconds (based on the size of the pan). This will provide a minimum amount of water in the pan and prevent heat damage to the humidifier pan. Humidifier lamps are OFF.

2.If the humidifier has been activated within the last 30 hours, Step 1 is bypassed. The autoflush will flow water into the pan for about 4 or 7 minutes (based on the lengths of time between humidifier activations). The humidifier lamps are on and the humidifier is operational during this period. When the pan is filled (the fill cycle has timed out), the water make-up valve is closed.

3.The water make-up valve remains OFF and the humidifier lamps are on for a maximum of 8 to 10 minutes (based on the size of the pan).

4.After the 8 to 10 minute time delay, the autoflush adds water to the pan to replenish the water used in humidification and flush the pan of mineral solids. This amount of water is adjustable from 110% to 500% in increments of 10%. At the end of this cycle, the make-up valve is closed. Steps 3 and 4 repeat as long as humidification is required.
