Pre-Electrical Checklist

√ Verify the voltage, frequency, and phase of the supply

source match the speciﬁcations on the unit rating plate.

√ Verify that the service provided by the utility is sufﬁcient

to handle the additional load imposed by this equipment.

See Table 2 or the unit wiring label for proper high and

low voltage wiring.

√ Verify factory wiring is in accordance with the unit

wiring diagram. See Figure 17 (page 34) & Figure

18 (page 35). Verify the connections didn’t loosen

during shipping or installation.

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 (next to the terminal block) for grounding

the unit.

Line Voltage

• Thelinevoltagetotheunitshouldbesuppliedfroma

dedicated branch circuit containing the correct fuse or

circuit breaker for the unit.

• A properly sized branch circuit and electrical

disconnect must be located within sight of and

readily accessible to the unit. This switch shall be

capable of electrically de-energizing the outdoor unit.

See unit data label for proper incoming ﬁeld wiring. Any

other wiring methods must be acceptable to authority

having jurisdiction.

• Useonlycopperwireforthelinevoltagepowersupply

to this unit. See Table 3, (page 12). Use proper

code agency listed conduit and a conduit connector for

connecting the supply wires to the unit. Use of outdoor

shielded conduit (metal lined Sealtite

) is recommended.

• Providepowersupplyfortheunitinaccordancewith

the unit wiring diagram and the unit rating plate.

• Removethecontrolpanelcover.Routethepowerand

ground wires (3 wires, including earth ground) from the

disconnect box to the unit.

• ConnectthelinevoltageleadstoL1 & L2 box lugs of

the high voltage terminal block, and the ground wire to

the grounding lug located above the terminal block.

• Replacethecontrolpanelcoverbeforeapplyingpower.

• 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 maximum circuit ampacity

and maximum overcurrent protection limits.

• Awiringdiagramislocatedontheinsidecoverofthe

control access panel of the outdoor unit. The installer

should become familiar with the wiring diagram (Figure

17 & Figure 18) before making any electrical connections

to the outdoor unit.

For 208Volt Operation Only:

• Unitsareshippedfromthefactorywiredfor240volt

transformer operation. For 208V operation, remove the

lead from the transformer terminal marked 240V and

connect it to the terminal marked 208V.

• Theinducermotorlowspeedresistormustbeby-passed

for 208 Volt operation. Remove the insulated quick

connect from one side of the resistor block and connect

to piggyback terminal on opposite side to complete

motor circuit.

Thermostat / Low Voltage Connections

• This Gas / Electric unit is designed to operate with

a 24 VAC Class II control circuit. The control circuit

wiring must comply with the current provisions of the

NEC (ANSI/NFPA 70) and with applicable local codes

having jurisdiction. Thermostat connections should be

made in accordance with the instructions supplied with

the thermostat.

• Theseunitsuseaspecialvariablespeedcompressorto

achieve a high level of efﬁciency in a compact frame. A

2 stage cooling / 2 stage heating 24V thermostat should

be used with this unit. See Figure 6 (page 12).

• 24VAC control power wiring must be routed to

interconnect the two-stage thermostat and the the units

low voltage terminal block. Recommended wire gauge

and wire lengths for typical thermostat connections are

listed in Table 4, (page 12).

• Eightwiresmustberuntothecontrolpanel.R, C, W,

W2, G, Y1, Y2, and L (if used) that originate at the

thermostat. Optional L provides a fault indication for

some thermostats.

• Thethermostatshouldbemountedabout5feetabove

the ﬂoor on an inside wall. DO NOT install the thermostat
