2. Refrigerant Oil Recovery Operation Flow
2.1 Refrigerant oil recovery operation monitor display
1. How to read the LED on the service monitor
Units' operation status can be monitored on the LED display by setting the dipswitches SW1-1 through 1-10 on the MAIN board of the
outdoor units.
Four 7-segment LEDs are used to display numerical values, flags, and alphabets to display various information.
The LEDs display such information as pressure and temperature in numerical values and operating conditions and the ON/OFF status of
solenoid valve as flags.
● Display of numerical values
Example:When the pressure sensor reads 18.8 kg/cm
* The unit of pressure is in kg/cm
* Use the following conversion formula to convert the displayed value into a value in SI unit (MPa).
SI unit (MPa) = Displayed value (kg/cm
● Flag display (Each set of two lines in vertical alignment indicates a flag.)
Example:Outdoor unit in the 3-minute restart delay mode. (Item No. 14)

(*1) The initial remaining time that indicates the refrigerant oil recovery is 80. A countdown will start on step 3 in the cooling mode.
The countdown does not include the time for checking the refrigerant charge amount.
(*2) S-1: Refrigerant oil recovery complete, S-0: Refrigerant oil recovery incomplete,
r-1: Refrigerant charge adjustment complete, r-0: Refrigerant charge adjustment incomplete.
