Make Electrical Connections

Be  sure field wiring complies with local and national fire, safety, and

electrical codes, and voltage  to system  is within limits shown on unit

rating  plate.  Contact local  power  company  for  correction  of  improper

voltage. See unit rating plate for recommended circuit protection device.

NOTE: 

Operation of unit on improper line voltage constitutes abuse and

could affect unit reliability. See unit rating plate. Do  not install unit in

system where voltage may fluctuate above or below permissible limits.

NOTE: 

Use copper wire only between disconnect switch and unit.

NOTE: 

Install  branch circuit disconnect of adequate size  per NEC to

handle unit starting current. Locate disconnect within sight and readily

accessible from unit, per Section 440-14 of NEC. Refer to Product Data

for breaker sizing.

Route Ground and Power Wires

Remove access panel to gain access to unit wiring. Extend wires from

disconnect  through  power  wiring  hole  provided  and  into  unit  control

box.

Connect Ground and Power Wires

This appliance incorporates an earth connection for safety purposes only.

Connect  ground  wire  to  ground  connection  in  control  box  for  safety.

Connect power wiring to contactor as shown in 

Fig. 6

.

Fig. 6 – Line Connections

Connect Control Wiring

Route 24-v control wires through control wiring grommet and connect

leads to control wiring.  Refer  to thermostat Installation Instructions for

wiring specific unit combinations (see 

Fig. 7

 ).

Use  No.  18  AWG  color-coded,  insulated  (35°C  minimum)  wire.  If

thermostat is located more than 100 ft. (30 m) from unit, as measured

along the control voltage wires, use No. 16 AWG color-coded wire to

avoid excessive voltage drop.
All wiring must be NEC Class 2 and must be separated from incoming

power leads. 
Use furnace transformer, fan coil transformer, or accessory transformer

for control power, 24v/40va minimum.

NOTE: 

Use of available 24v accessories may exceed the minimum 40va

power requirement. Determine total   transformer loading  and increase

the transformer capacity or split the load with an accessory transformer

as required.

WARNING

!

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Do  not  supply  power  to  unit  with  compressor  terminal  box  cover

removed. 

WARNING

!

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

The  unit  cabinet  must  have  an  uninterrupted  or  unbroken  ground  to

minimize personal injury if an electrical fault should occur. The ground

may  consist  of  electrical  wire  or  metal  conduit  when  installed  in

accordance with existing electrical codes.
