ELECTRICAL CONNECTIONS

 WARNING:

To avoid electric shock, personal injury, or death, 

turn off the electric power at the disconnect or the 

main service panel before making any electrical 

connections.

•  Electrical  connections  must  be  in  compliance  with 

all applicable local codes and ordinances, and with 

the current revision of the National Electric Code  

(ANSI/NFPA 70).

•  For  Canadian  installations  the  electrical  connections 

and grounding shall comply with the current Canadian 

Electrical Code (CSA C22.1 and/or local codes).

Pre-Electrical Checklist:

 Verify that 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. 

refer to the unit wiring label for proper high and low 

voltage wiring.

  Verify factory wiring is in accordance with the unit wiring 

diagram. See 

Figure 13 (page 16) 

Figure 14 (page 

17)

. Inspect for loose connections.

Line Voltage

•  It is recommended that the line voltage to the unit be 

supplied from a dedicated branch circuit containing the 

correct fuse or circuit breaker for the unit. 

• 

An 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.

•  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. Extend leads 
through power wiring hole (

Figure 5

). Connect 

L1

 & 

L2

 

directly to the contactor.

•  Use only copper wire for the line voltage power supply 

to this unit. 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.

•  See the unit wiring label for proper high and low voltage 

wiring. Make all electrical connections in accordance 

with all applicable codes and ordinances.

 CAUTION:

Label all wires prior to disconnection when 

servicing controls. Wiring errors can cause 

improper and dangerous operation. Verify proper 

operation after servicing.

• 

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.

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.

Overcurrent Protection

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. 

Generally, the best fuse or breaker for any heat pump 

is the smallest size that will permit the equipment to run 

under normal usage and provide maximum equipment 

protection. Properly sized fuses and breakers also prevent 

nuisance trips during unit startup. 

If a fuse blows or a 

breaker trips, always determine the reason.

 

Do not 

arbitrarily install a larger fuse or breaker and do not, 

in any case, exceed the maximum size listed on the 

data label of the unit.
