Outdoor Units
1. The System Combination Ratio must be
between 50–130%. See page 55 for more
information.
2. All communication cables must comply with
applicable local codes.
3. Rated using non-ducted indoor units. Rated
0 ft. above sea level with 25 ft. of refrigerant
line per indoor unit and a 0 ft. level difference
between outdoor and indoor units. All capaci-
ties are net with a Combination Ratio between
95–105%. Certifi ed under the AHRI Unitary
Small Heat Pump equipment certifi cation pro-
gram and tested per AHRI Standard 210/240
conditions and in accordance with DOE test
procedures. Nominal Cooling capacity rating
obtained with air entering the indoor coil at
80°F dry bulb (DB) and 67°F wet bulb (WB)
and outdoor ambient conditions of 95°F dry
bulb (DB) and 75°F wet bulb (WB). Nominal
Heating capacity rating obtained with air
entering the indoor unit at 70°F dry bulb (DB)
and 59°F wet bulb (WB) and outdoor ambient
conditions of 47°F dry bulb (DB) and 43°F
wet bulb (WB).
4. Unit is capable of operating outside the
operating range temperature limitations. See
"Select the Outdoor Unit" on page 52.
5. Sound pressure levels are tested in an
anechoic chamber under ISO Standard 1996.
6. Power wiring cable is fi eld provided and must
comply with the applicable local and national
codes.
