Page 24: Performance Curves
PERFORMANCE CURVES The standard data contained in these specifications apply only to the operation of the air conditioner under normal conditions. Since operating conditions vary according to the areas where these units are installed. The following information has been provided to clarify the operating characteristics of the air conditioner under the conditions indicated by the performance curve.

Only indoor fan operates.Outdoor unit does not operate. 5. FAN MOTOR CONTROL (1) Rotational frequency feedback control The indoor fan motor is equipped with a rotational frequency sensor, and outputs signal to the microprocessor to feedback the rotational frequency.
Page 32 (3) Positioning The vane is once pressed to the vane stopper below to confirm the standard position and then set to the desired angle. The positioning is decided as follows. (a) When the OPERATE/STOP button is pressed. (POWER ON/OFF) (b) When the vane control is changed from AUTO to MANUAL. (c) When the SWING is finished.
Page 33 8. TIMER OPERATION 1. How to set the timer (1) Press OPERATE/STOP button to start the air conditioner. (2) Check that the current time is set correctly. NOTE : Timer operation will not work without setting the current time. Initially “AM0:00” blinks at the current time display of TIMER MONITOR so set the current time, correctly with CLOCK SET button.
Page 34: Service Functions
9. EMERGENCY-TEST OPERATION When the remote controller is missing, or has failed, or when the batteries run down, press the EMERGENCY OPERATION switch on the front of the indoor unit. The unit will start and the OPERATION INDICATOR lamp will light. The first 30 minutes of operation will be the test run operation.

AUTO RESTART FUNCTION MS-07NV - MS-09NV - MS-12NV - MS-24NV - MS-18NV - When the indoor unit is controlled with the remote controller, the operation mode, set temperature, and the fan speed are memorized by the indoor electronic control P.C.board. The “AUTO RESTART FUNCTION” sets to work the moment power has restored after power failure.Then, the unit will restart automatically.
