Installation - Exterior Grille
(Cont.)
Architectural Exterior
(Rear) Grille
The architectural rear grille directs condenser airflow
and provides a protective barrier for the outdoor coil.
Either the approved Standard or Architectural grille must
be installed before installing the chassis.
1. Install the four threaded studs into the threaded open-
ings on the inside face of the grille. Install a washer
and one hex nut to the end of each stud.
2. Manipulate the grille out through the rear plenum open-
ing. Be sure to keep a firm grip on the grille to pre-
vent it from dropping and/or causing possible injury
or property damage.
3. Attach the grille to the plenum by aligning and inserting
the hex nut threaded onto the studs through the holes
in the plenum.
4. Secure the grille to the plenum by tightening the hex nut
and adding and tightening an additional hex nut.
