3.2.4 DISTILLED WATER CONNECTION
The system automatically siphons distilled water from its Distilled Water Reservoir located in the lower cabinet. A
1/8” diameter flexible tube is pre-installed into the tank to siphon water from the tank bottom. It passes through
the tank’s cover screw, through a fitting in the lower cabinet, connects through a fitting on the upper cabinet,
connecting finally to the presaturator fill pump. As these tubes and connections are pre-installed at the factory,
there are no other additional connections to make for distilled water.
3.2.5 SYSTEM DISCHARGE CONNECTION
There is a ½” pipe connection on the rear corner of the cabinet for discharge of air, water vapor, and condensate
removed via the air drier.
If your pressurized air source is dry, and you generally operate the
humidity generator at a temperature no warmer than 25 °C, you will
likely never see any water coming from the discharge connection.
However, if you utilize the internal air compressor, or operate the
generator at chamber temperatures above 25 °C, condensation may
occur at this discharge connection. The higher the chamber temperature
and humidity, the more condensation will be present.
You may, if desired, connect a ½” NPT fitting and tube to direct this
discharge away from the system to a small drip pan or a floor drain. A
drip pan volume of 0.5 to 1 liter is generally sufficient.
3.3 INITIAL PREPARATION
3.3.1 COMPUTER CONNECTION
The system is supplied with its own built-in computer and monitor on the right-side front panel door. Enable the
computer, monitor, and internal control system by pressing the front panel power switch located below the
monitor in the upper right cabinet panel. The switch should illuminate, the monitor should activate, and the
operating system (Windows 10) should boot. Follow section 4.1 through 4.2.1 to launch the RHS Control program
and connect to the CGS-240 Humidity Generator.
Interaction with the system is via touch screen or physical mouse/keyboard. To utilize the physical
mouse/keyboard, plug them into the USB connectors located at the upper right rear of the system.
Additional connectors (HDMI and RS-232) are also available at the same location. The HDMI connector is for
attachment of an additional external monitor if desired. The RS-232 connector allows connection of an external
computer system if desired. An external computer system could be utilized to operate the generator in the event
of needed firmware updates, secondary system monitoring, or alternate data collection. This connection may also
