9-12 THE DISPLAY SHOWS
“
”
• This is the case immediately after the main
power supply switch is turned on and means
that the remote controller is in normal condi-
tion. This continues for 1 minute.
9-13 THE COMPRESSOR OR FAN IN THE
OUTSIDE UNIT DOES NOT STOP
• This is to prevent oil and refrigerant from
remaining in the compressor. The unit will
stop after 5 to 10 minutes.
9-14 THE INSIDE OF OUTSIDE UNIT IS
WARM EVEN WHEN THE UNIT HAS
STOPPED
• This is because the crankcase heater is warm-
ing the compressor so that the compressor
can start smoothly.
9-15 HOT AIR IS EMITTED EVEN THOUGH
THE UNIT IS STOPPED
• Hot air can be felt when the unit is stopped.
Several different indoor units are being run on the
same system, so if another unit is running, some
refrigerant will still flow through the unit.
9-16 DOES NOT COOL VERY WELL
• Program dry operation.
Program dry operation is designed to lower the
room temperature as little as possible.
Refer to page 8.
