4.2 Notices for Unit Debugging
(1) Before conducting the debugging, please ensure that the compressor has been preheated
for more than 2 hours, and check whether the preheating is normal by hand. Debugging can
be started up only when the preheating is normal, otherwise the compressor may be
damaged.

(2) When starting up the debugging, the system automatically selects the operating mode
according to the current ambient temperature.
(3) When debugging, the front panel of the outdoor unit must be completely closed, otherwise it
will affect the accuracy of debugging (as shown in the Fig. as below).
