Goodman HUM-SFTBP Installation And Mounting Manual

Installation Instructions and Mounting Template
ADDITIONAL WARNINGS:
1. Disconnect electrical power to the furnace before start-
ing installation to avoid serious injury or electrocution.
2. Use care when cutting plenum openings and handling
ductwork. Sharp edges may cause serious injury.
3. Do not cut or drill any air conditioning or electrical
accessories during humidifier installation. (See Mounting
Diagram C, below.) Electrocution is possible if you come
in contact with a live electrical wire. Blindness can occur if
refrigerant contacts your eyes.
CAUTIONS:
1. Do not install the unit where freezing temperatures could
occur, or where temperatures could exceed 180°F.
2. Do not install the unit on a furnace jacket.

Step-by-Step Installation Instructions
1. Locate the duct-cutting
template at the top of the
reverse side of this sheet.
Detach the template from
these instructions at the
perforation. Tape the
template lengthwise onto
the furnace plenum,
making sure it is level.
5.
Pull out the drip tray

2.
Trace around the
template. (Cutout size is
9" wide by 10" long.)
Remove the template.
Accurately cut the plenum
opening.
6. To convert the humidi-
fier from right- to left-side
discharge, apply pressure
to the inside of the side
panel using both hands.
Lift. Exchange the two
side pieces. Reinstall
using moderate pressure.
10.
Reattach the cover
assembly by hooking it at
the top of the mounting
frame, then securing it

3. Do not install the unit on a plenum face where the
blanked-off ends of the cooling coil restrict air movement
through the humidifier.
4. Do not set humidity higher than recommended. Conden-
sation damage may result.
5. Do not set humidity up to recommended levels if there is
condensation on the inside windows of any unheated
living space. Condensation damage may result.
6. Do not install the unit on any plenum where static pres-
sure exceeds 0.4" W.C.
7. Do not install the unit where water pressure exceeds 125
psi. Leakage may result. Follow relevant codes regarding
pressure reduction.
8. Be sure that the installation, wiring and plumbing on the
humidifier comply with local codes, ordinances and
regulations.

Explanation of A/B Options
Mounting the humidifier on the warm air supply or the cold air
return plenum does not alter humidifier performance. In either
location, air will flow from the warm air to the cold air side, due
to the positive and negative pressures of the heating system.
Humidity produced by a bypass flow-thru humidifier is dispersed
as a pure vapor (i.e., gas), not as a liquid. The moisture will
remain in the air, even when reheated. The humidity can only be
depleted by escaping to the outside, or by condensing on a cold
surface. Because all surfaces in the furnace/humidifier system
are warm, condensation is unlikely.

fier cover from the mount-
ing frame by rotating the

make the connection.
Screw the 6" duct to the
discharge collar.
Summer Shutoff Damper
The Summer Shutoff Damper is designed to reduce the
bypass of air through the humidifier during the summer
months, allowing the air conditioner to run more efficiently and
economically. The homeowner merely needs to turn the knob
on the bypass collar to "summer" or "winter", depending on the
season.
Other than restricting air flow during cooling, or limiting humi-
difier efficiency in winter, no harm is done if the homeowner
fails to open or close the damper at the appropriate times.
