line Voltage

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

electrical box of the outdoor unit. The installer should 

become familiar with the wiring diagram before making 

any electrical connections to the outdoor 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.

•  Line voltage to the unit should be supplied from a dedicated 

branch circuit containing the correct fuse or circuit breaker 

for the unit. Incoming field wiring 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 the wiring diagram / 

schematic for identification and location of outdoor unit 
field wiring interfaces. See 

Figure 4

Figure 5

Figure 6

Figure 7

. 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.

•  208/230 Volt units are shipped from the factory wired for 

230 volt operation. For 208V 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.

•  When  connecting  refrigerant  linesets  together,  it  is 

recommended that dry nitrogen be flowing through the 

joints during brazing to prevent internal oxidation and 

scaling.

•  Refrigerant  tubing  should  be  routed  in  a  manner  that 

minimizes the length of tubing and the number of bends 

in the tubing. If precise forming of refrigerant lines is 

required, a copper tubing bender is recommended. Avoid 

sharp bends and contact of the refrigerant lines with metal 

surfaces.

•  Refrigerant tubing should be supported in a manner that the 

tubing will not vibrate or abrade during system operation.

•  Tubing  should  be  kept  clean  of  foreign  debris  during 

installation.

•  Every effort should be made by the installer to ensure that 

the field installed refrigerant containing components of 

the system have been installed in accordance with these 

instructions and sound installation practices to insure 

reliable system operation and longevity.

•  The maximum recommended interconnecting refrigerant 

line lengths is 75 ft. and the vertical elevation difference 

between the indoor and outdoor sections should not exceed 

20 ft.

•  A filter dryer is provided with the unit and must be installed 

in the liquid line of the system. If the installation replaces a 

system with a filter dryer already present in the liquid line, 

the filter dryer must be replaced with the one supplied with 

the unit. The filter dryer must be installed in strict accordance 

with the manufacturer’s installation instructions.

•  Optional equipment such as liquid line solenoid valves, 

low ambient, etc., should be installed in strict accordance 

with the manufacturer’s installation instructions.

electrical Wiring

 Warning:

electrical ShocK or Fire haZard

to avoid risk of electrical shock, personal injury, 

or death, disconnect all electrical power to the unit 

before performing any maintenance or service. the 

unit may have more than one electrical supply.
label all wires prior to disconnection when 

servicing the unit. Wiring errors can cause improper 

and dangerous operation.

•  All  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 voltage wiring.

 Verify factory wiring is in accordance with the unit wiring 

diagram. See
