Desert Spring Furnace Humidifier
Installation Guide

7. Installing the Lid and Adjusting the Water Level

• Fit the lid onto the basin.
• Turn on the water supply and check for any leaks.
• The float assembly should be adjusted so that the height of the water is within the range indicated by the textured bands on the inside sides of the basin. The water should just cover the disks (look into the inlet to see the water level).
• Adjust the float as required.
• Secure the float adjustment nut with a ⁹/₁₆-inch wrench.
• As an additional convenience, you may wish to run a hose from the overflow hole to your floor drain. The necessary parts are available from your local plumbing supplier.
