Active Clean freezes and then rapidly thaws the indoor heat exchanger so condensed water can help wash away accumulated dust, mold, and grease. The indoor fan then uses warm air to dry the evaporator. The indoor display shows CL while the cycle is running, and the cycle normally ends automatically after about 20 to 45 minutes.

Yes. The MIA manual lists an Auto-Restart function that restores operation using the prior settings after power is restored.

Breeze Away changes the airflow pattern to reduce direct air blowing on occupants. The remote-controller manual lists this function for COOL, FAN, and DRY modes. Feature availability can vary by exact model, so confirm that the Breeze Away symbol or button is supported by the unit.

The manual lists 6,000 BTU MIA models in 115V; 9,000 BTU models in 115V or 230V; 12,000 BTU models in 115V or 230V; and 18,000 and 24,000 BTU models in 230V. Confirm the exact voltage and model number before ordering or installation.

CL indicates that Active Clean is running, dF indicates a defrost cycle, and FP indicates the 46°F (8°C) heat-maintenance function. The display can also show the temperature, operating-feature indicators, wireless-control status, timer status, and error codes.

ECO and GEAR are available in COOL mode. ECO uses an automatic fan setting and, when the setpoint is below 75°F (24°C), adjusts it to 75°F to reduce energy use. GEAR cycles through approximately 75% and 50% electrical-consumption limits before returning to the previous setting. Reduced-energy modes can also reduce cooling output.

FHCC indicates a refrigerant-sensor malfunction on models equipped with that sensor. The manual lists a 15-year sensor service life and states that the sensor is not repairable; it must be replaced with the manufacturer-specified sensor by qualified service personnel.

Follow Me uses the temperature sensor in the remote controller instead of relying only on the indoor-unit sensor. In AUTO, COOL, or HEAT mode, the remote sends its measured temperature to the unit about every three minutes so the system can regulate comfort closer to the remote location. A memory option can keep Follow Me active through certain mode changes or power interruptions.

FP is a low-temperature heat-maintenance function for heat-pump models. The remote manual describes activating it while the unit is in HEAT mode with the setpoint at 60°F (16°C). The system then operates at high fan speed while the compressor is running and targets approximately 46°F (8°C).

The manual lists the mounting plate and cardboard template, drain joint, seal, anchors, mounting-plate screws, two copper nuts, remote controller, two batteries, and one or two small filters among the supplied items. The remote-controller holder and its screws, refrigerant piping, connection cable, and outdoor-unit power cable are shown as separate or model-dependent items. Always compare the carton contents with the exact model packing list.

The documented pairs are: 6K 115V - CH-RLS06MIA-115VI with CH-RLS06MIA-115VO; 9K 115V - CH-RLS09MIA-115VI with CH-RLS09MIA-115VO; 9K 230V - CH-RLS09MIA-230VI with CH-RLS09MIA-230VO; 12K 115V - CH-RLS12MIA-115VI with CH-RLS12MIA-115VO; 12K 230V - CH-RLS12MIA-230VI with CH-RLS12MIA-230VO; 18K 230V - CH-RLS18MIA-230VI with CH-RLS18MIA-230VO; and 24K 230V - CH-RLS24MIA-230VI with CH-RLS24MIA-230VO.

The installation summary shows at least 5.9 inches (15 cm) above the indoor unit, more than 4.72 inches (12 cm) on each side, and at least 70.87 inches (1.8 m) from the floor. The wall hole is generally 2.5 inches (65 mm) when the gas line is smaller than 5/8 inch, or 3.54 inches (90 mm) when the gas line is 5/8 inch or larger. The hole should slope downward toward the outdoors by approximately 0.2 to 0.275 inch (5 to 7 mm).

The manual requires a minimum piping run of 9.84 feet (3 m) and notes that nominal efficiency is tested with 25 feet (7.5 m) of piping. Maximum listed lengths and vertical drops are: 9K/12K - 82 feet maximum with 49.2 feet maximum drop; 18K - 98.4 feet with 65.6 feet drop; and 24K - 164 feet with 82 feet drop. Final design should follow the exact model submittal and installation requirements.

The MIA installation table lists 9K and 12K models with a 1/4-inch liquid line and 3/8-inch gas line; 18K with a 1/4-inch liquid line and 1/2-inch gas line; and 24K with a 3/8-inch liquid line and 5/8-inch gas line. The table does not clearly list the 6K piping size, so use the model submittal or unit labeling for that size.

Yes. The MIA manual lists Louver Angle Memory, which returns the louver to its previous angle when the unit is turned on again.

Yes, for emergency or testing use. With the unit off, open the indoor front panel and locate the Manual Control button on the right side. Press once for Forced Auto, press again for Forced Cooling, and press a third time to turn the unit off. Regular operation should be restored with the remote controller.

The MIA manual describes an outdoor heat-exchanger dust-removal function. After the unit is turned off, there is approximately a 10-second delay and the outdoor fan runs in reverse for about 70 seconds to blow away loose dust and debris. This feature can help keep the coil cleaner, but it does not replace normal inspection and maintenance.

The MIA manual states that a buzzing sound is heard each time the air conditioner is powered on to confirm normal power-up. If no sound is heard, the manual recommends powering the unit on again or checking the electrical circuit.

The MIA Series models covered by this manual use R454B refrigerant. R454B is identified as an A2L flammable refrigerant, so installation, leak testing, charging, recovery, and service should be performed by qualified personnel using procedures and equipment suitable for R454B.

Yes. The manual states that the bottom of the indoor unit should be at least 6.0 feet (1.8 m) above the floor and the room height should not be less than 7.3 feet (2.2 m). The required minimum room area depends on the system refrigerant charge and installation height, so the model-specific table and installation documentation must be checked before installation.

On MIA units equipped with a refrigerant sensor, a detected leak causes the indoor unit to show an error code and sound a buzzer. The outdoor compressor stops immediately and the indoor fan starts running. The manual states that the unit should remain powered except while it is being serviced so the detection system can operate.

The remote controller is designed to support several related unit configurations, so some buttons or icons may not apply to every MIA model. If the indoor unit does not support a function, pressing that button has no effect. When the remote manual and the unit owner manual differ, follow the MIA owner manual for the installed model.

In COOL mode, Sleep raises the set temperature by 2°F (1°C) after the first hour and another 2°F (1°C) after the second hour. In HEAT mode, it lowers the set temperature by the same amount during each of the first two hours. The Sleep adjustment ends after eight hours and the system continues at the final setting. Sleep is not available in FAN or DRY mode.

In HEAT or AUTO-heating mode, holding the Turbo button for more than five seconds activates Super Heat. The louver opens to its maximum angle and the system prioritizes faster heating, especially in low outdoor temperatures. Hold Turbo for more than three seconds to stop it. The manual notes that discharge air may initially feel cooler because the anti-cold-air feature is temporarily disabled.

The MIA documentation lists wireless control for app-control units and identifies a Smart Kit on the manual cover. To begin network configuration, select AP mode through the remote SET menu. If AP mode does not start through SET, the remote manual instructs pressing the LED button seven times within 10 seconds. Wireless availability should be confirmed for the exact MIA model.
