Connecting the Water Supply (HUMD311-1, -4 option)
This applies to units that have the HUMD311-1,-4 humidity option.
To ensure proper operation, distilled or deionized water is required as a supply on units
that have humidity control. If these water sources are not available contact CARON
customer service.
A water inlet fitting on the back of the unit and ¼” black tubing are provided to connect
the water supply to the chamber. Connect an appropriate water supply to the fitting.
Incoming line pressure should be regulated to not exceed 80 psi.
If a Condensate Recirculator water recycling system was purchased as a water supply,
refer to its user’s manual for proper installation.
