1.3.1 Water supply

The HumiSteam must be supplied with water (not softened) having the

following characteristics:

The water feed line should be 1/2” copper, PVC or poly tubing run to within 3 feet of the humidifier, then bushed

down to 1/4” O.D. or 3/8” O.D. copper or poly to make the final connection to the 1/4” O.D. or 3/8” O.D.

compression fitting underneath the humidifier. With poly tubing an insert should be used to support the tubing

and prevent leaks. This insert is not provided.

NOTE: Softened water should NOT be used as it is generally corrossiv e to the electrode plating.

The drain line can be 1-1/2” schedule 40 CPVC, 1-1/2” copper, or 1-1/2” Polypropylene. In all cases, the drain

tube is slipped over the drain outlet on the bottom of the humidifier. It is not glued or otherwise attached to the

humidifier, so it must be supported by itself.

Drain line must be installed and plumbed to an open drain immediately after the unit.

For proper operation of the unit, the open drain should be installed before the trap (if allowed by local code).
