2.2.2.3 Self-Regenerating Dehumidification System Set-Up
The standard self-regenerating dehumidification system is contained
entirely within the chamber control section.
If house air is used, a quick disconnect air fitting will be installed on the
Chamber Side Interface Panel.
2.2.2.4 Operation
To operate the self-regenerating system proceed as follows:
1. Open the chamber vent by removing the supplied 1” green Caplug.
2. The Chamber Vent, inside of the chamber, is the 1” opening on the
right wall (the green plug should be removed). The vent passes
through to the outside right wall. the 1” barb on the outside should
also remain open.
The Model 578 is a positive pressure system. Without adequate
ventilation, the System will pressurize the working space.
Pressurizing the Chamber is not recommended and may cause
damage.
3. Set the microprocessor humidity controller set-point to a value
below ambient humidity.
4. Turn on the “RH” STANDBY switch on the front panel.
This will do two things:
a. It will activate the high-pressure pump and the dual column
dryer. They will begin producing dry air as soon as the “RH”
STANDBY switch is turned on. However, no dry air will be
allowed into the chamber workspace until the 3-way control
valve is energized.
b. Turning on the “RH” STANDBY switch makes the 3-way
control valve available to the microprocessor controller.
When the microprocessor controller tells the control valve to
energize, the small red LED in the lower right corner of the
Humidity display will light. The valve will open and dried air
will flow into the chamber workspace.
