1. Rated in accordance with AHRI Standard 110-2012, utilization range A.
2. Dual element fuses or HACR circuit breaker. Maximum allowable overcurrent protection.
3. Dual element fuses or HACR circuit breaker. Minimum recommended overcurrent protection.
4. Rotary compressor models are limited to an equivalent length of refrigeration piping of 100 ft with no exceptions.
5. Refer to the Hard Start Kit Accessory Installation Manual for the hard start kit part number for each model. The hard start kit is a field installed accessory.
6. For applications with non-standard vapor line sizes, refer to the APPLICATIONS AND ACCESSORIES section in the Technical Guide.
7. The unit charge is correct for the outdoor unit, smallest matched indoor unit, and 15 ft of refrigerant tubing. For tubing lengths other than 15 ft, add or subtract the
amount of refrigerant, using the difference in actual refrigeration piping length (not the equivalent length) multiplied by the per foot value.
‡ The adapter fitting must be field installed for the required 1 1/8 in. refrigeration piping.
