5 Maintenance

WARNING: Cleaning the air filter and other parts involves work in high places. This should be performed by a qualified installer or service person. Do not attempt it yourself.

CAUTION: Do not push buttons with wet hands, as this may result in electric shock.

Cleaning the Air Filters

• Clean air filters when the filter indicator is displayed on the remote controller (for RBC-AMTU*** and RBC-AMSU*** models). Clogged filters reduce cooling and heating performance.
• When the unit will not be used for a long time: Perform fan operation for a couple of hours to dry the interior, stop the unit, turn off the circuit breaker, and clean the air filters before reinstalling them.

Before the Cooling Season

Clean the drain pan. Contact the dealer where the product was purchased. A clogged drain pan or vent can cause water overflow, wetting walls or floors.

Maintenance List

NOTE: For environmental conservation, regular cleaning and maintenance of indoor and outdoor units are recommended for efficient operation. Periodic maintenance (once a year) is advised for long-term use. Check the outdoor unit for rust/scratches and treat as necessary. For units operated 8+ hours daily, clean indoor/outdoor units every 3 months by a professional. Proper maintenance extends product life. Failure to clean can lead to poor performance, freezing, water leakage, and compressor failure.

6 Troubleshooting

Check the following points before requesting repair. Some symptoms are not malfunctions.

If an unusual situation persists after checking, stop the unit, turn off the circuit breaker, and contact the dealer with the product number and symptom. Do not attempt self-repair. If a check indicator (e.g., E, F, H) is displayed on the remote controller LCD, inform the dealer of the code.

If any of the following occur, stop the unit immediately, turn off the circuit breaker, and contact the dealer:

• The switch does not work properly.
• The circuit breaker frequently blows out.
• Foreign objects or water have entered the unit unintentionally.
• The unit cannot be run even after the cause of protective device activation is removed.
• Other unusual conditions are found.

Confirmation and Check

If an unusual situation persists after checking, stop the unit, turn off the circuit breaker, and contact the dealer with the product number and symptom. Do not attempt self-repair. If a check indicator (e.g., , , ) is displayed on the wired remote controller LCD, inform the dealer of its content.

If the air conditioner fails, the timer off indicator will alternately display the check code and the number of the faulted indoor unit.

Troubleshooting History and Confirmation

You can view the troubleshooting history (up to 4 records) when the air conditioner is on or off. Viewing history during timer off operation will cancel the timer.

1. Step 1: Long press the timer off button for over 10 seconds until an indication icon appears, signifying entry into troubleshooting history mode. If "Maintenance overhaul" is displayed, you have entered this mode. The temperature display will show "01: Troubleshooting History Order". The timer off indication will alternate between [Check Code] and [Indoor Unit Number]. Press the Set button to view history in order from [01] (newest) to [04] (oldest).
2. Step 2: REQUIREMENT: Do not press the Menu button for more than 10 seconds in this mode, as it will delete all troubleshooting history.
3. Step 3: After checking, press the ON/OFF button to return to normal mode. If the unit is running, it will continue. Press ON/OFF again if the unit is stopped.

7 Operations and Performance

Check before running

• Check if the earth wire is cut or disconnected.
• Check if the air filter is installed.
• Turn on the circuit breaker 12 hours or more before starting operation.

3 minutes protection function

This function prevents the air conditioner from starting for the initial 3 minutes after the main power switch or circuit breaker is turned on for restarting.

Power failure

A power failure during operation will stop the unit completely. To restart, push the ON/OFF button on the remote controller. Lightning or nearby wireless devices may cause malfunction. Turn off the power switch/breaker, then turn them back on. Push the ON/OFF button to restart.

Defrosting operation

If the outdoor unit is frosted during heating, defrosting starts automatically (2-10 minutes) to maintain heating capacity. Indoor and outdoor unit fans stop during defrost. Defrosted water drains from the outdoor unit's bottom plate.

Heating capacity

Heating operation uses a heat pump system, absorbing heat from outside. If the outside temperature is very low, using an additional heating apparatus is recommended.

Protective device

• The unit stops operation when overloaded. If the protective device activates, the operation and check indicators on the remote controller blink.
• If the protective device is activated: Turn off the circuit breaker and perform a checkup. Continued running may cause malfunction. Check if the air filter is installed; if not, the heat exchanger may clog, leading to water leakage.

During cooling

• The air intake or discharge of the outdoor unit is clogged.
• Strong wind continuously blows against the outdoor unit's outlet.

During heating

• The air filter is clogged with dust.
• The air intake or discharge of the indoor unit is clogged.

Do not turn off the circuit breaker

During the air-conditioning season, leave the circuit breaker on and use the ON/OFF key on the remote controller.

Attention to snowfall and freeze on the outdoor unit

• In snowy areas, air intake/discharge can be covered by snow or ice, potentially causing machine failure or poor warming.
• In cold areas, ensure the drain hose drains water properly without freezing to prevent machine failure or poor warming.

Air conditioner operating conditions

For optimal performance, operate within these temperature conditions:

CAUTION: Operating outside these conditions may activate safety protection.

8 Installation

Do not install the air conditioner in the following places:

• Within 1 m of TVs, stereos, or radios (to prevent noise interference).
• Near high-frequency appliances (e.g., sewing machines, massagers) to avoid malfunction.
• In humid, oily, steamy, sooty, or corrosive gas environments.
• In salty areas (e.g., seaside).
• In places with significant machine oil use.
• In areas exposed to strong winds (e.g., seaside).
• In places with sulfureous gas generation (e.g., spas).
• In vessels or mobile cranes.
• In acidic or alkaline atmospheres (e.g., hot-spring areas, near chemical factories) to prevent corrosion of heat exchanger fins and pipes.
• Near obstacles (vents, lighting) that disturb air discharge (may reduce performance).
• For special purposes like food preservation, precision instruments, or housing animals/plants (may degrade quality).
• Over objects that must not get wet (condensation may drip).
• In places where organic solvents are used.
• Near doors or windows with humid outside air (may cause condensation).
• In places where special sprays are used frequently.

Be careful with noise or vibrations

• Do not install where outdoor unit noise or hot air discharge annoys neighbors.
• Install on a solid, stable foundation to prevent noise and vibration transmission.
• Some sound may be audible from other indoor units not operating if one is running.
