beginning installation. Do not install where temperatures fall below 32 degrees F or where plenum temperatures
exceed 200 degrees F. When wiring into a multi-speed blower circuit see wiring diagrams.

INSTALLATION: The humidifier may be mounted with the 6"
outlet to the right or left by inverting the cabinet and reversing
the positions of the distributor trough and drain pan. The
humidifier may be mounted on the warm or return air plenum
with equal efficiency.
See Typical Installations.

The Braeburn model 220500/220550 may be installed on
either the supply or return plenum of a forced air handling
system. The 220500/220550 is reversible for installation with
bypass duct connections on the right or left side of the
cabinet. The outer dimensions of the cabinet are 13 1/2” wide
X 15” high X 9 1/2” deep. Select a location for the humidifier
that allows for service.

Connect by-pass pipe to collar and humidifier cabinet. Using
holes at top and bottom of side panel discharge, pierce 2
self tapping screws through by-pass pipe.

2

Cut out center section of template and 6” hole. Humidifier is self
retaining. Slide top side in first, then slide chassis down. Level
chassis and install center screws. If by-pass pipe installs to
opposite side of chassis, bend clip on chassis, remove side
discharge, and reinstall discharge to opposite side of chassis.
Install remaining four corner screws.

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 and a plastic sleeve
on the outside with a brass compression nut.

NOTE: DO NOT USE PLASTIC TUBING ON HOT WATER OR IN
CONT ACT WI TH ANY H OT PLE NUM SURFACE OR DUCT.
INSTALLATION OF THIS SADDLE VALVE MUST MEET OR
EXCEED LOCAL CODES AND ORDINANCES.

Turn damper knob to winter (open) position.
Turn on water supply and check operation of
humidifier. Set humidistat to a demand setting. With
the furnace off, the solenoid valve should be closed.
Start the furnace. The solenoid valve should open
when the blower or burner circuit is energized.
Check flow of water through distributor trough and
evaporator pad. The standard yellow orifice will
supply approximately 3.5 GPH of water at a line
water pressure of 60 psi. Leave humidistat set at the
recommended setting.
