Component Operation and Maintenance

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 seconds. 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 minutes. 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 9-1/2 minutes.

4.After the 9-1/2 minute 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.

Autoflush Controls

Use the LCD display, menu, and keys on the front control panel to program the autoflush controls.

6.5.2Steam Generating Humidifier

Steam generating humidifiers are designed to operate in voltage ranges from 200 to 575 volts and generate 11 pounds (5 kg) of steam per hour. These humidifiers operate efficiently over a wide range of water quality conditions and automatically adjust to changes in the conductivity of water. The humidifiers drain and refill to maintain an amperage setpoint and alert the operator when the humidifier canister needs to be replaced. The humidifier is in the lower section of upflow units; it is in the middle section of downflow units.
