Step 5.
Place the supply collar plate (
M701 or M271-38
) on the top of the unit - center it and use a marker to dot the location
of the holes, remove plate and drill
a 1/16’’Ø pilot hole.
Step 6.
Place a continuous
¼” bead of white or clear silicone around the perimeter of the top of the unit before placing the
collar plate on top of the unit
Step 7.
Use the self-tapping screws to fix the plate on to the top of the unit permanently.
For units built with serial numbers greater than 75288 the 3 black grills will be mounted on a
separate removable plate (AR336-02). This will make the transition from Recirculation to
Negative pressure collar discharge a simple task. The plates will be removable and
interchangeable with no cutting required.
To convert AF2000 units simply remove the discharge grill (H001), apply some caulking to the
10”collar plate (H184) and screw down the plate over the discharge opening using the hardware
provided.
