Installation
2. AUUH728C/AUUH1008C
For additional charging method, see below table.
❈ Note: If total additional charge value after calculation comes out to be negative, then do not consider additional
charge.
CAUTION:
• Rated performance for refrigerant line length of:7.5m
• Capacity is based on standard length and maximum allowance length is on the basis of
reliability.
• Improper refrigerant charge may result in abnormal cycle.
• Oil trap should be installed every 10 meters.
