Page 296: Pump Down Operation
14-4. Pump down WARNING During the pump down operation, make sure that compressor is off before you remove the refriger- ant piping. Do not remove the connection pipe while the compressor is in operation with valve open. This may cause abnormal pressure in the refrigeration cycle that leads to breakage and even injury.
Page 297 7. Disconnect the power supply or turn off the breaker. NOTE: If the pump down is not stopped by pressing the switch as in step 6, it will stop auto- matically after 15 minutes and the LED will light as follows. If the pump down is com- plete, disconnect the power supply or turn off the breaker.
