Figure 1—Option A:
Duct Edge Mount
CAUTION: For all installation congurations, the mounting area must
be strong enough to support the humidier’s weight when it is full of
water (approximately 18 lbs.), and to hold the humidier in a level position
for safe, reliable operation. Otherwise, additional duct reinforcement 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 extending
at least 6 feet downstream from the humidier.
Mount the unit at least 4-to-6 feet after the plenum transition. Avoid sudden 5.
turns or transitions in the ductwork in the immediate area downstream from
the humidier.
Mounting the Humidier
Option A is the preferred method of
mounting because it requires the least
amount of duct reinforcement to support
the humidier 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 humidier 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 contact
with a live electrical wire; blindness can
occur if refrigerant contacts your eyes.
To install (Option A):
Place the mounting bracket (provided) 1.
on the edge of the ductwork where the
humidier is to be installed.
Use a marker to trace around the inside of the mounting bracket. Cut out 2.
the duct opening.
CAUTION: DO NOT attach the mounting bracket before the hole in the
ductwork has been cut.
Attach the mounting bracket to the ductwork with sheet metal screws. 3.
