Field Splitting Instructions — If components are split, maxi- mum 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 evaporator. Liquid line tubing is 3/8-in. OD copper tubing, and discharge line is 1/2-in. OD copper tubing. 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 wiring should be a minimum of no. 16 AWG, 4/64-in. thick insulation. Check all applicable electri- cal codes to ensure proper compliance.
