• Make sure that there is no gap between the unit and the grille, or between the grille
and the surface of the ceiling. If there is any gap between the unit and the grille, or
between the grille and the surface of the ceiling, it may cause dew to collect.
• Make sure that the wires have been securely connected.
• For PLP-6BAE, PLP-6BAMDE, PLP-6BALME, check the rotating movement of
the i-see sensor. If the i-see sensor does not rotate, review the procedure in "9.6.
Installation of i-see sensor corner panel".
By using the maintenance mode, you can display many types of maintenance data
on the remote controller such as the heat exchanger temperature and compressor
current consumption for the indoor and outdoor units.
This function can be used whether the air conditioner is operating or not.
During air conditioner operation, data can be checked during either normal opera-
tion or maintenance mode stable operation.
* This function cannot be used during the test run.
* The availability of this function depends on the connecting outdoor unit. Refer to
the brochures.
