These instructions are primarily intended to assist qualified
individuals experienced in the proper installation of heating
and/or air conditioning appliances. Some local codes require
licensed installation/service personnel for this type equipment.
All installations must be in accordance with these instructions
and with all applicable national and local codes and standards.
Before beginning the installation, read these instructions
thoroughly and follow all warnings and cautions in the instructions
and on the unit. When performing brazing operations have a
fire extinguisher readily available and use a quenching cloth
and brazing shield.
Improper installation, service, adjustment, or maintenance can
cause fire, electrical shock or other conditions which may result
in personal injury or property damage. Unless otherwise noted
in these instructions, only factory authorized kits or accessories
may be used when modifying this product.

INTRODUCTION
These instructions are for the installation of a Variable Speed
Conversion Kit in an air handler with blower relay, manufactured
after August 1999. Refer to the Air Handler Installation Instructions
for details necessary for the proper set-up of the unit. A copy is
included with this kit.
INSTALLATION (Air Handlers with Blower
Relay) GB3
1. Parts packages "GB3" and "common parts" will be required
to complete this conversion.
2. Remove and discard strain-relief bushing from the blower
deck.
3. Disconnect and pull blower motor wires back through the
blower deck.
4. Remove blower.
5. Remove green wire from spade terminal of the blower relay
and discard.
6. Attach the variable speed circuit board and bracket to the
rail of the blower assembly with the 2 screws provided.
7. Install variable speed blower.
8. Connect the 6 low voltage wires from the low voltage wire
harness supplied with the kit to the variable speed blower
board as shown in the wiring diagram. See Figure 2.
9. Cut the white 6-pin plug from the low voltage wire harness
that was just connected to the variable speed blower board.
10. Route wires through hole in blower deck.
Note: If the unit has or will have a heater kit installed, move
to step 13.
11. Connect the 3-wire (black, white and green) plug supplied
with parts package to the mating connection on the motor.
Note: Make sure ground wire is attached to the blower
housing assembly with screw provided in parts package.
12. This step required for units without heater kits. Separate
the black and white wires coming directly from the motor.
Cut the terminals off and strip the ends of the black and
white wires. Connect them to the power leads as shown in
the wiring diagram. Secure with wire nuts. See Figure 2.

13. On air handler units that have or will have an electric heater
kit installed, separate the black and white wires coming
directly from the blower motor. Attach the white motor wire
to the open terminal on the circuit breaker or terminal strip
on the same pole as the red wires. Connect the black wire
to the open terminal on the circuit breaker or terminal strip
on the same pole as the black wires.
14. Route the low voltage wires from the harness through the
bushing located in the top of the electrical panel along with
the existing thermostat leads.
15. Connect the thermostat wiring as shown in Figure 1.
16. Attach wiring diagram (710288) supplied with parts package
to the front of the blower housing.
