Note:
• The normal voltage range is rated in accordance with AHRI Standard 110-2012, utilization
range A.
• Dual element fuses or HACR circuit breaker. Maximum allowable overcurrent protection.
• Dual element fuses or HACR circuit breaker. Minimum recommended overcurrent
protection.
• The unit charge provided is less than the system total charge required. Select the
appropriate indoor section and lineset length charge additions to calculate additional
charge required and total system charge.
• For applications with non-standard vapor line sizes, see
