FIXED OUTDOOR AIR INTAKE DAMPER
This damper assembly is shipped inside the return air
compartment. It is completely assembled and ready for
installation. A damper baffle inside the hood is adjustable to
provide variable amounts of outdoor air intake on units that are
not provided with an economizer or motorized damper option.
Refer to Figure 3.
Gasketing and mounting screws are provided in a parts bag
attached to the hood assembly. Apply gasketing to the three
flangesurfaces on thehood prior toinstallingthe hood. Extend
gasketing approximately 6mm (1/4") beyond the top and
bottom of the two side flanges to ensure adequate sealing.
Adjusting the damper to the desired air flow may be done
before mounting the hood into position or (after installation) by
removing the front hood panel or the screen on the bottom of
the hood. Damper baffle in position 1 will allow approximately
10%recirculatedairflow,position2approximately15%and,to
allow approximately 25%, remove the damper baffle.
On units with bottom return air applications, install the damper
assembly over the opening in the side return air access panel.
Remove and discard the opening cover and the covering over
the hood mounting holes (used for shipping) before installing.
Secure with the screws provided.
Onunitswith side air applications, installthedamperassembly
on the return air ductwork as close to the unit as possible. Cut
an opening 406mm (16") high by 457mm (18") wide in the
ductwork to accommodate the damper. Using the holes in the
hood flanges as a template, drill 3.6mm (9/64") dia. (#26 drill)
holesintotheductworkandsecurewiththescrews provided.
CAUTION: If outdoor air intake will not be required on units
with bottom return air applications, the damper as-
sembly should still be mounted on the side return
air access panel, per the instructions above, to en-
sure moisture is not drawn into the unit during op-
eration.Thecoveringoverthemounting holesonly
need be removed. Do not remove the opening
cover.
CONDENSATE DRAIN
Plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install a condensate drain
line from the 25mm (1" NPT) female connection on the unit to
spill into an open drain.
An alternate drain connection (25mm [1" NPT] female
coupling) is provided inboard on the same centerline as the
exterior location.
NOTE: The condensate drain line MUST be trapped to pro-
vide proper drainage. See Figure 4.
