1) Unless otherwise specified, leave the switch to OFF where indicated by "-," which may be set to OFF for a reason.
2) When set to the capacity priority mode and if the following conditions are met, the quiet mode will terminate, and the unit will
go back into the normal operation mode.
Cooling-only/Cooling-main: Outside temperature is high or high pressure is high.
Heating-only/Heating-main: Outside temperature is low or low pressure is low.
3) The factory settings for dipswitches SW3-7 and SW4-7 are ON. The table below summarizes the factory settings for SW5-1
through SW5-4, and SW5-7. The factory settings for all other dipswitches are OFF. Switching SW4-7 to OFF during the oil
recovery operation does not stop the oil recovery operation, which is scheduled to last for 3 hours and half.
4) The refrigerant oil recovery operation can be cancelled and normal operation can be started if Stage 3 in the cooling mode or
Stage 4 in the heating mode has been completed. To cancel the operation, set the SW4-7 to OFF.
