Figure 1—Option A:
Duct Edge Mount
CAUTION
: For all installation configurations, the mounting area
must be strong enough to support the humidifier’s weight when it is
full of water (approximately 18 lbs.), and to hold the humidifier in a level
position for safe, reliable operation. Otherwise, additional duct reinforce-
ment will be necessary.
NOTE
: If the installation includes exposed insulated materials, a section
of the ductwork must be removed and replaced with rigid metal duct ex-
tending at least 6 feet downstream from the humidifier.
5. Mount the unit at least 4-to-6 feet after the plenum transition. Avoid
sudden turns or transitions in the ductwork in the immediate area down-
stream from the humidifier.
Mounting the Humidifier
Option A is the preferred method of
mounting because it requires the least
amount of duct reinforcement to support
the humidifier and keep it level. A duct
width of at least 10 inches is necessary.
Wider ducts may need to be reinforced in
order to hold the humidifier level.
DANGER
: Wear safety glasses when
cutting or drilling. Do not cut or drill into
any air conditioning components or electri-
cal enclosures during installation. Electro-
cution is possible if you come in con-
tact with a live electrical wire; blind-
ness can occur if refrigerant contacts
your eyes.
To install (Option A):
1. Place the mounting bracket (provided)
on the edge of the ductwork where the
humidifier is to be installed.
2. Use a marker to trace around the inside of the mounting bracket. Cut out
the duct opening.
CAUTION
: DO NOT attach the mounting bracket before the hole in the
ductwork has been cut.
3. Attach the mounting bracket to the ductwork with sheet metal screws.
