Model 1000 Humidier Installation Manual

Breathe Healthier! Residential Whole-House Indoor Air Quality

Installation

1. Select a location on the vertical surface of warm air plenum
of a forced air handling system for mounting humidier that
allows for service and maintenance. Do not install humidier
where the blanked off ends of a cooling coil will restrict air
ow to the humidier. Cut out a square section 12-1/8” tall
by 14-1/8” wide as shown.

2. Open the cover and remove the evaporator pad assembly.
The humidier chassis is self retaining. Slide the top side
in rst, then slide the chassis down. Level the chassis and
install the eight screws (included).

3. Mount the self tapping saddle valve on either a cold or a hot
water pipe. A side or top mount is best to avoid clogging
from pipe sediment. Connect 1/4” O.D. tubing to the saddle
valve. Copper tubing requires a brass compression nut and
brass sleeve. Plastic tubing requires a brass insert inside the
tubing in addition to a plastic ferrule and brass nut.

CAUTION: do not use plastic tubing on hot water or in
contact with any hot plenum surface or duct. Installation
of this saddle valve must meet or exceed local codes and
ordinances.

4. Connect 1/4" water supply tube to inlet of solenoid.

Connect drain hose to 1/2" spout on humidier cabinet using
hose clamp if necessary. Run 1/2" hose to suitable drain
such as oor drain, sewer or laundry sink. Be sure hose has
continuous slope and is not kinked at any point.
