Anchoring The Ceiling Unit Ventilator
Anchor the unit using the four unit mounting holes. The unit
must be suspended from these holes ( Figure 39 on page
19 ). Do not attempt to suspend the unit at any other
locations. When hanging the horizontal AH unit ventilator, the
unit should be level both front to back and side to side. This
aids in condensate removal from the drain pan, and reduction
of sound and vibration. Use an 8 foot level to determine the
unit is not twisted or pitched.
Unit must be anchored to an internal ceiling column or other suitable
support. Anchoring the unit improperly can result in personal injury,
damage to property, and impact unit performance.
CAUTION !
Refer to Figure 37 on page 18 and Figure 39 on page 19
and attach the unit ventilator to the ceiling through the four
(4) 7/8" (22.2 mm) diameter mounting holes provided, using
field-supplied fasteners appropriate to the ceiling construction
and the washers provided in the brown envelope with these
instructions. The envelope also contains an allen wrench
to provide access to the unit. These holes must be used to
suspend the unit. Do not attempt to suspend the unit from any
other points. Hanger rods are normally used to suspend the
unit, (see Figure 37 on page 18 ).
It is the responsibility of the installer to provide mounting
hardware in accordance with local codes.
Ensure that the unit is properly level and not twisted. Use the unit
mounting holes. Do not attempt to suspend the unit from any other
points. A twisted and unlevel unit will cause poor performance due
to vibration.
CAUTION !
Use an 8 foot level to ensure front to back and side to side
are level. Twisting can result in unit vibration due to out of
alignment of rotating components (fans, fan shaft, and motor).
This can also cause premature motor failure.
Ceiling Unit Ventilators can be mounted in an exposed position,
in a soffit, partially recessed, fully recessed and concealed
(see Figure 4 on page 6 ). For partially and fully recessed
units, wall guard flanges are a standard accessory to provide a
finished appearance at the ceiling ( Figure 40 ).
One-inch duct collars are provided for field duct attachment to
the supply-air outlet. The duct collars are field installed. Locate
the unit ventilator as close as practical to the outdoor air intake
opening. Insulate the outdoor air duct to reduce sweating or
temperature rise (see Figure 23 on page 13 ).

Recess Flange (See Notice)
1" Duct Collar
Assemble Recess Flange and then attach to ceiling T bar or
plaster board. Recess Flange must not make contact with unit,
to prevent transmission of any vibration ( Figure 40 ).
Do not attach or hang the ceiling off of the unit ventilator.
