Factory-Mounted Unit Options

Unit Disconnect (FIYUDC)

Important:

All phases of this installation must comply 
with NATIONAL, STATE, and LOCAL 
CODES. In addition to local codes, the 
installation must comply with National 
Electric Code - ANSI/NFPA NO. 70 LATEST 
REVISION.

1.

Field connections are made by first removing the 
compressor access panel on the front of the unit. 
Unscrew the assembly around the outside of the 
disconnect switch. This assembly is located in the 
condenser section of the unit.

For down flow configurations, the hole in the base 
section is for both high and low voltage power wiring 
on down flow units. Horizontal units will route through 
the holes in the front corner post where the disconnect 
enclosure is mounted. The hole is sized for 1 1/2” 
conduit.

2. If the conduit required for your application is larger, 

remove the termination plate and connect to the larger 
hole using field supplied reducing washers.

3. Route the power wires and ground conductor through 

conduit and into the bottom of the factory installed 
disconnect switch. Connect the power conductors to 
the lugs provided. Connect the ground wire to the unit 
ground lug.

Note:

Wire size for the length of run should be 
determined using the circuit ampacity found on 
the unit nameplate and the N.E.C.

4. Route low voltage (class II), control wiring through 

hole in base of unit but not through high voltage 
conduit. Feed control wiring through bushing provided 
on side panel. Route wires through loose wire ties 
provided. 

5. Tighten the wire ties. Secure the excess wire bundle 

under the wire ties in the outdoor section. Do not leave 
excess wire in the electrical enclosure. Use the unit 
wiring diagram to make the low voltage connections.

WARNING

Hazardous Voltage w/Capacitors!

Disconnect all electric power, including remote 
disconnects and discharge all motor start/run 
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be 
inadvertently energized. Verify with an appropriate 
voltmeter that all capacitors have discharged. Failure to 
disconnect power and discharge capacitors before 
servicing could result in death or serious injury. 

For additional information regarding the safe discharge 
of capacitors, see PROD-SVB06A-EN 

WARNING

Proper Field Wiring and Grounding 
Required!

All field wiring MUST be performed by qualified 
personnel. Improperly installed and grounded field 
wiring poses FIRE and ELECTROCUTION hazards. To 
avoid these hazards, you MUST follow requirements for 
field wiring installation and grounding as described in 
NEC and your local/state electrical codes. Failure to 
follow code could result in death or serious injury.
