NOTE

This performance chart shows operation of a single wall-mounted indoor unit. The performance chart will vary depending on the indoor unit type.

Check each performance value in test-run mode. Electrical performance values represent a combined indoor/outdoor value. (In this case, be sure to stop all the indoor units where performance is not being checked.)

The performance is for a tubing length of 24.6ft (7.5m). If the tubing length is different, the performance chart will vary.
