1. INDOOR UNIT
Operation can be checked by lighting and flashing of the
display section OPERATION, TIMER, and VERTICAL SWING
lamps.
Perform judgment in accordance with the following.
TEST RUNNING
When the air conditioner is run by pressing the remote control
unit test run button, the OPERATION, TIMER, and VERTICAL
SWING lamps flash slowly at the same time.
ERROR
The OPERATION, TIMER, and VERTICAL SWING lamps
operate as follows (Table 1) according to the error contents.
2. OUTDOOR UNIT
When the outdoor temperature drops, the outdoor unit's fans
may switch to low speed, or one of the fans may stop
intermittently.
ERROR : Reverse cycle only
The LED lamps operate as follows (Table 2) according to the
error contents.
Table 2
2003.12.17
When the fault is cleared, the LED lamp goes off.
However, for discharge pipe temperature abnormal and high
pressure abnormal, the LED lamp lights continuously for 24
hours, as long as the power is not turned off.
