Typical piping and wiring

LEGEND

NEC — National Electrical Code

NOTES:

1.Wiring and piping shown are not intended for or to include all details for specific installation.

2.All wiring must comply with applicable local and national codes.

3.All piping must follow standard refrigerant piping techniques. Refer to Carrier System Design Manual, Part 3, for details.

4.For other installation details refer to Installation Instructions.

5.If unit sections are field split, 8 threaded support rods are required.

6.Ensure condenser air recirculation is minimized.

Field splitting instructions — If components are split, maximum length of refrigerant tubing to be used is 50 ft, assuming components are installed in same horizontal plane. Condenser may be mounted up to 12 ft above evap- orator. Liquid line tubing is 3/8-in. OD copper tubing, and discharge line is 1/2-in. OD copper tubing. For additional piping information, refer to Carrier System Design Man- ual, Part 3. Units should always be within line of sight from each other, or separate NEC (National Electrical Code)

disconnects will be required. Junction boxes should be installed in both the evaporator and condenser sections adjacent to D-shaped grommets, to provide a location to splice the outdoor-fan motor factory wiring (no. 16 AWG [American Wire Gage], 4/64-in. thick insulation). Field wir- ing should be a minimum of no. 16 AWG, 4/64-in. thick insulation. Check all applicable electrical codes to ensure proper compliance.
