Installation, Operating and Maintenance Manual

Connect Water Drain
The humidifier periodically drains some hot water to
remove mineral build-up in the steam cylinder. This
water is generally in the range of 140 to 200°F, so the
drain piping must be CPVC or copper.
The drain line should be 1-1/2” diameter CPVC. Slip the
1-1/2” pipe over the drain outlet on the bottom of the
humidifier as shown at right. Do not glue to the
humidifier.
A trap must be used in the drain line directly below the
humidifier to prevent flash steam from rising into the
humidifier unit and condensing on components.
WARNING: Failure to install a drain trap as
instructed will void the warranty.
Instant maximum drain water flow = 0.40 gpm
Connect Water Feed
A plastic and brass quick connect fitting is supplied for
connection of the water feed line. This fitting includes a
¼” O.D. compression fitting which mates to standard ¼”
O.D. plastic or copper tubing.
Inside the fill valve connection is a plastic strainer which
must be removed for periodic maintenance. Make sure
that your installation will allow the plastic fitting to be
removed for maintenance.
WARNING: Hand tighten only.
DO NOT USE DEMINERALIZED WATER.
Instant maximum feed water flow = 0.30 gpm
