• To check the revolution of the fan, check the inverter output state on the LED screen, as the inverter on the out-
door fan controls the revolutions of the fan. The revolution of the fan is approximately 600rpm at full speed.
• When starting the fan, the fan runs at full speed for 5 seconds.
• For the 2 fans for P450-P650 types, the fan on the right (as you face the fan) runs at all times and the fan on the
left runs when required. (When heating except for defrost, both fans run.)
• When setting the DIP SW1 to
, the inverter output [%] will appear. 100% indicates the full
speed and 0% indicates the stop.
• As the revolution of the fan changes under control, at the interphase or when the indoor unit operation capacity is
low, the revolution of the fan may change.
• When the fan does not work or an abnormal vibration occurs, the FAN board is defective, or the fan motor runs
under open phase or opposite phase. (The microcomputer detects the open phase or the opposite phase of the
main power source, however, these malfunctions may occur when doing other service work or when the lead wire
for the fan motor is intentionally replaced.)
• When the only one fan is running and the other fans are stopped, check the 52F output state on the LED screen
first and check the fan connector and 52F connector misconnection, 52F failure, or the lead wire disconnection.
