All electrical connections should be done by a

qualified electrician.

1. To replace the Honeywell Limit Control (A): Unplug from

power supply

The control may be removable thru the access panel on item

“B”. However it may be easier to remove item “B” entirely for bet-

ter access. Remove item “B” by means of the eight(8) screws. If

siliconed, use a utility knife to score the silicone along the edges

of the part. Take off the cover of the control (A), remove the

three wires, and continue to remove the control by means of the

two screws retaining it. Use the wiring diagram in the rear of this

manual to re-connect the new control. Reattach item “B” and

re-silicone all the seams with weather resistant silicone.
2. To remove the return air box (D): Unplug from power supply.
If siliconed, use a utility knife to score the silicone along the edges

of the part. Remove item “B” as described above. Then remove

the four(4) screws down each side and the four(4) across the top

of the return air box. Pull the box back away from the unit enough

that you can reach in to remove the snap-in plug (C) from the

top of the box. The power supply cord will need to be feed back

thru the plug in the bottom of the air box for complete removal.

When re-attaching, make sure that the three plugs in the top of

the Fan Center (G) are properly plugged in. Do not forget to put

the snap-in plug (C) back in place. Re-silicone all the seams with

weather resistant silicone.
3. To remove the Distribution Blower (E): Unplug from power

supply.

Remove items”B” and “D” as described above. Unplug the blow-

er from the top of the Fan Center (G). Remove the four(4) screws

retaining the blower.
4. To remove the Blower Motor: Unplug from power supply.
Perform number 3 above. Before removing the motor from the

housing, measure two things:
1.) The distance from the edge of the motor to the edge of the

motor bracket. Record (d1) _________________
2.) The distance of the shaft remaining outside the coupling on

the blower wheel. Record (d2) __________________
These two measurements dictate the position of the blower in-

side the housing and is critical in determining motor longevity.

Repositioning of the blower motor, bracket, and wheel in respect

to one another should keep as close to the factory position as

possible.
Remove the three(3) screws (I) from the blower housing. Then

loosen the bolt (J) on the motor shaft. Next, loosen or remove the

bolt (K) in the motor bracket to remove the motor.
5. To remove the Blower Capacitor (F): Unplug from power supply.
This may be accomplished by working thru the 12 inch diameter

return duct hole in the Return Box. Otherwise, you must remove

items”B” and “D” as described above. Unplug the blower from

the top of the Fan Center (G). Using pliers with rubber coated

handles, unplug the two connections on the capacitor. Remove

the two screws and cap bracket.
