(1) Low pressure performance chart
(2) Operating current performance chart
(3) Indoor discharge air performance chart

• 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 24.6t (7.5m). If the tubing length is different, the performance chart will vary.
