and minimum size of electrical conductors and circuit
protection must be in compliance with information listed
on the outdoor unit data label. Any other wiring methods
must be acceptable to authority having jurisdiction.
• The outdoor unit requires both power and control circuit
electrical connections. Refer to Figure 8 (page 15)
for identification and location of outdoor unit field wiring
interfaces. Make all electrical connections in accordance
with all applicable codes and ordinances.
• Overcurrent protection must be provided at the branch
circuit distribution panel and sized as shown on the unit
rating label and according to applicable local codes.
See the unit rating plate for minimum circuit ampacity
and maximum overcurrent protection limits.
• Provide power supply for the unit in accordance with the
unit wiring diagram, and the unit rating plate. Connect
the line-voltage leads to the terminals on the contactor
inside the control compartment.
• Use only copper wire for the line voltage power supply
to this unit as listed in Table 1 . Use proper code agency
listed conduit and a conduit connector for connecting
the supply wires to the unit. Use of rain tight conduit is
recommended.
• Units are shipped from the factory wired for 240 volt
operation. Remove the lead from the transformer terminal
marked 240V and connect it to the terminal marked
208V.
• Optional equipment requiring connection to the power
or control circuits must be wired in strict accordance of
the NEC (ANSI/NFPA 70), applicable local codes, and
the instructions provided with the equipment.

Grounding
WARnInG:
the unit cabinet must have an uninterrupted or
unbroken electrical ground to minimize personal
injury if an electrical fault should occur. Do not
use gas piping as an electrical ground!
This unit must be electrically grounded in accordance
with local codes or, in the absence of local codes, with
the National Electrical Code (ANSI/NFPA 70) or the CSA
C22.1 Electrical Code. Use the grounding lug provided in
the control box for grounding the unit.
Blower Speed
The blower speed is preset (for operation) at the factory
for heating and cooling. These factory settings are listed
in Table 5 (page 19) . For optimum system performance
and comfort, it may be necessary to change the factory
set speed.
cAUtIon:
to avoid personal injury or property damage,
make sure the motor leads do not come into
contact with any uninsulated metal components
of the unit.
1. Shut off all electrical power to the unit and remove
the blower panel. Locate the orange and red wires
terminated to the blower motor. notE: The orange wire
controls cooling operation while the red wire controls
heating operation.
2. Verify the required speed from the airflow data found
in Table 5 . Place appropriate wire on the correct motor
speed tap for the required airflow point.
thermostat connections
• The Q6SE heat pump may require a 2-stage cooling /
heating thermostat if used in conjunction with certain
installed accessories. Refer to your manual for additional
instructions.
• The low voltage wires must be properly connected to
the units low voltage terminal block as shown in Figure
7 (page 14) . Recommended wire gauge and lengths
for typical thermostat connections are listed in Table 2
(page 10) .
• The l terminal on the defrost control board is used for
fault monitoring. This is a 24V output and may be used
with compatible thermostats. Refer to the thermostat
manufacturer's manual to ensure compatibility.

• The thermostat should be mounted about 5 feet above
the floor on an inside wall. DO NOT install the thermostat
on an outside wall or any other location where its
operation may be adversely affected by radiant heat from
fireplaces, sunlight, or lighting fixtures, and convective
heat from warm air registers or electrical appliances.
