Error contents

Operation can be checked by lighting and flashing of the display section OPERATION,
TIMER, and VERTICAL SWING lamps. Perform judgment in accordance with the following.

TEST RUNNING

When the air conditioner is run by pressing the remote control unit test run button,
the OPERATION, TIMER, and VERTICAL SWING lamps flash slowly at the same time.

DANGER

This part (Choke coil) generates high voltages.
Never touch this part.

SPECIAL INSTALLATION
SETTING

PUMP DOWN (Refrigerant collecting operation)

Perform the following procedures to collect the refrigerant when moving
the indoor unit or the outdoor unit.

(1) Press the push-button switch (SW2) on the circuit board once.

The LED on the circuit board starts flashing (one second ON/one se­cond OFF). This indicates the start of PUMP DOWN operation.
When the switch is pressed while the compressor is in operation, PUMP
DOWN operation starts automatically.
When the switch is pressed while the compressor is in stop, the com­pressor starts to operate automatically, and then move on to PUMP
DOWN operation.

(2) PUMP DOWN operation continues for about 1 minute. When PUMP

DOWN operation is completed, the compressor stops automatically.
Then close the 2-way valve and 3-way valve immediately.

(3) Turn the power off.

ERROR CONTENTS
(outdoor unit)

1. Make a TEST RUN in accordance with the in­ stallation instruction sheet for the indoor unit.

2. OUTDOOR UNIT LEDS

When a malfunction occurs in the outdoor unit, the LED on the circuit
board lights to indicate the error. Refer to the following table for the de­scription of each error according to the LED.
