Rated Indoor Airflow (cfm)
Tables 5-7 list the rated indoor airflow used for the AHRI (Air-
Conditioning, Heating, and Refrigeration Institute) efficiency
rating for the units covered in this document.
Unit Positioning
The unit can be mounted on the floor for vertical application
with return air entering the face of the unit and supply air dis
-
charging vertically through the top of the unit. The unit can
also be applied in a horizontal arrangement with return air
entering horizontally and the supply air discharging horizontal
-
ly. When applying the unit in a horizontal arrangement, ensure
the condensate drain pan is located at the bottom center of the
unit for adequate condensate disposal. See Fig
.
5 for conden
-
sate connections for each unit position.
Fig. 5 — Typical Unit Positioning
Typical positioning and alternate return air locations are shown
in
Fig. 5. Alternate return air locations can be used by moving
the unit panel from the alternate return air location to the stan
-
dard return air location. Refer to overhead suspension accesso
-
ry drawing (see Fig. 6) for preferred suspension technique. The
unit needs support underneath to prevent sagging.
Unit Isolation
Where extremely quiet operation is essential, install isolators
between floor and base of unit, or between ceiling and top
section of unit.
Be sure that unit is level and adequately supported. Use
channels at front and sides of unit for reference points when
leveling.
