Section 2. General Information
This electric heater accessory is designed to provide
power directly to the air handler from the accessory
heater's power supply, eliminating the need for additional circuits. The power and control wiring each use
a single wire harness to connect the heater and the air
handler.
1. Check the heater nameplate to confirm that the selected
heater is approved for use with the air handler.
2. Check the components received for damage. Report any
defects or shortages to the transportation company immediately.
3. Be sure the power supply matches the listing shown on
the heater nameplate.

Section 4. Heater Selection
Determine which heater best fits your application needs. In addition to electrical considerations, you must know your
cabinet size and the range of heaters which fit that cabinet.
4.1 Air Handler Model Number Matrix
Step 1 - Measure your cabinet and use the Air Handler
Model Number Matrix to determine your cabinet size.

Section 5. Adjust Heater
STEP 1 - Position Width Adjustment Brackets.
Two Width Adjustment Brackets are located at the
back of the heater assembly. The heater comes
sized for the smallest cabinet it will fit in. For this
example our heater fits cabinets A, B, and C. It came
sized for an A cabinet and we are sizing it for a B
cabinet.
1. Loosen the screws that hold the Width Adjustment
Brackets to the back of the heater.
2. Reposition each Width Adjustment Bracket until the
correct holes line up with the loosened screws as illustrated in this step.
3. Tighten screws to hold Width Adjustment Bracket
securely in place.
INSTALLER'S GUIDE
Width Adjustment Brackets
(two per unit)
Cabinet A
The heater comes from the factory sized for cabinet
A. No modifications to the Width Adjustment
Brackets are required.
Cabinet B
Prepare the heater for cabinet B by modifying the
Width Adjustment Brackets to align with the holes
labeled B.
Cabinet C
Prepare the heater for cabinet C by modifying the
Width Adjustment Brackets to align with the holes
labeled C.
STEP 2 - Adjust Filler Plates.

Cabinet A
NOTE: No Filler Plates are required for the A cabinet.
Cabinet B or C
1. Loosen the Filler Plate screws on each side of Base
Plate (four total).
2. Slide in the correct Filler Plate on each side. Filler
Plates are marked for the cabinet size they match
with, for example, the Filler Plate for cabinet B is
marked "B-CAB".
3. Tighten the Filler Plate screws loosened previously
and add a screw (provided) to the bottom of each
plate to hold Filler Plates in place.
