ERROR CONTENTS
REMOTE CONTROL UNIT
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 on the circuit board once.
The LED on the circuit board starts flashing (one second ON/one se-cond
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 com-pressor
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
1. Make a TEST RUN in accordance with the
installation instruction sheet for the indoor unit.
2. OUTDOOR UNIT LEDS
OUTDOOR UNIT
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.
CAUTION
Always turn on the power 12 hours prior to the start of the
operation in order to ensure compressor protection
