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 better 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 blower 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
inside 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.
