SECTION IV OPERATING INSTRUCTIONS

Start-up Instructions

1.Check that the humidifier is properly mounted and level.

2.Check that the water fill and drain are properly connected.

3.Check that the correct voltage and amperage services are supplied.

4.Check all controls are wired properly.

5.Check that the steam distributor is properly installed and that the steam hose has been properly routed without any kinks or flat spots.

6.With power off, double-check all electrical connections and plumbing connections to insure that they did not loosen during shipment.

7.With the "on-off-drain" switch in the "off” position, and the control and high limit (ducted versions only) humidistats at their lowest settings, turn on the main disconnect. The contractor should remain deenergized and the power light should remain "off”. Place the “on-off-drain" switch in the "on" position and the power light should illuminate.

8.Turn the control and high limit (ducted versions only) humidistats up to there highest setting. The contractor should pull in.

9.After approximately a twenty second delay, the fill valve should open and water begins to fill the cylinder to the preset amp level or cylinder full condition, depending on the incoming water supply. When starting up the unit, it is best to put an amp clamp on the power leg that passes through the

NOTE

If upon initial start-up of this humidifier the cylinder is slow in heating and/or the service light continues to come on, drain the tank to 1/4 full. Turn off power at breaker and crumble 1/2 of one tablet (Alka-Seltzer) from the envelope tagged EST-1583 included with unit into the grey fill tee. Change the middle blue dial on the left side of the circuit board, R18, from 90% to 87%. Then turn the breaker on and run the unit. If you have had to use these this step on a 230V unit (6000-2,4), it is advisable that you order a GT-176-1 replacement cylinder rather than the standard replacement cylinder in the future so this procedure will not need to be repeated. Upon receipt of the GT-176-1 cylinder, adjust the dial, R18, on the circuit board back to 90%.

torroid transformer. Insure that the humidifier fills to "cylinder full" (approximately 1.5” from the top of the cylinder), or that the amperage reaches the data plate maximum and the fill valve closes.

10.All units are equipped with a drain-tempering feature which mixes cold fill water with the hot drain water to protect drain piping. Depending on your fill water pressure, some adjustment of the fill metering valve may be necessary to insure drain water of less than 140 degrees F (See Figure 9). To deactivate, remove diode from socket CRI8 from circuit board (See Figure 12).

11.Reset control and high limit humidistats to there desired settings. Typical control humidistat settings are 30-40% and limit humidistat settings are 65- 70%.

NOTE

The capacity of the humidifier can be adjusted between 500% and 100% of the maximum level by adjusting the capacity adjustment potentiometer (labeled R39) on the main circuit board. All blower versions are set from the factory to produce 4 lbs/hr. If the psychrometric conditions permit, the 6000—2 may be increased to 8 lbs/hr by adjusting R39 from 50% to 100% capacity.

CAUTION!

Inadequate airflow may allow humidity to collect in areas causing condensation.
