2. When the product is operating:  
1
Press the PUMP DOWN switch on the outdoor unit.  
The LED on the outdoor unit circuit board lights, and  
operation stops. At this point, recovery has not been  
completed, so do not close the two- and three-way  
valves.  
2. OUTDOOR UNIT LEDS  
When a malfunction occurs in the outdoor unit, the LED on
