Ensure that no dirt or debris enters the tubing. The standard tubing length is 15 ft., 5M.
If a different length is required, adjust the refrigerant amount by 1/4 oz/ft, 20 g/M for the
9k, 12k and 18k models. For the 24k model, adjust by 1/2 oz/ft, 40 g/M.Before opening
the service valves, evacuate the interconnecting tubing and indoor unit. Follow the
instruction in section 5 on page 4.
