Why Fujitsu Inverter Halcyon Air Conditioner doesn’t operate immediately?
Your Fujitsu Air Conditioner might not start immediately due to these reasons: * If the indoor unit is stopped and restarted, the compressor won't operate for about 3 minutes to prevent fuse issues. * After turning the electrical breaker off and on, the protection circuit operates for about 3 minutes, preventing immediate operation.
Why is my Fujitsu Inverter Halcyon not cooling or heating properly?
Several factors can cause poor cooling or heating performance in your Fujitsu Air Conditioner. Check the following: * Ensure the air filter is clean. * Make sure the intake grille or outlet port are not blocked. * Verify the room temperature settings (thermostat) are correctly adjusted. * Close any open windows or doors. * For cooling, close curtains to block bright sunlight. * Reduce heat-generating appliances or the number of people in the room. * Check if the unit is set to SUPER QUIET operation.
What to do if my Fujitsu Inverter Halcyon doesn't operate at all?
If your Fujitsu Air Conditioner isn't operating at all, consider these potential causes: * Check if the circuit breaker has been turned off. * Verify if there has been a power failure. * Inspect whether a fuse has blown out or a circuit breaker has been tripped. * Confirm if the timer is operating correctly.
How to fix a Fujitsu Inverter Halcyon Air Conditioner that doesn't operate immediately?
Your Fujitsu Air Conditioner may not operate immediately after being turned on due to the following reasons: * If the indoor unit is stopped and immediately restarted, the compressor will not operate for about 3 minutes to prevent fuse blowouts. * If the electrical breaker is turned off and then on again, the protection circuit will operate for about 3 minutes, preventing unit operation.
What to do if my Fujitsu Inverter Halcyon Air Conditioner doesn’t operate at all?
If your Fujitsu Air Conditioner isn't operating, check the following: * Ensure the circuit breaker is turned on. * Verify there hasn't been a power failure. * Check for blown fuses or tripped circuit breakers. * Confirm the timer isn't in operation.
Why is my Fujitsu Inverter Halcyon airflow weak or stops?
There are several reasons why your Fujitsu Air Conditioner's airflow might be weak or stop: * When heating starts, fan speed is temporarily low to warm internal parts. * During heating, if the room temperature exceeds the thermostat setting, the outdoor unit stops, and the indoor unit operates at very low fan speed. * During heating, the indoor unit may temporarily stop (7-15 minutes) for Automatic Defrosting. * In Dry mode, the indoor unit operates at low speed and may stop to adjust humidity. * SUPER QUIET operation mode lowers fan speed. * In AUTO mode, the fan operates at very low speed. * For Multi-type units, operating multiple units in different modes can cause units to stop and the OPERATION indicator lamp to flash.
Why is water produced from the outdoor unit of my Fujitsu Air Conditioner?
During Heating operation, water may be produced from the outdoor unit of your Fujitsu Air Conditioner due to Automatic Defrosting operation.
Why is the airflow weak or stopping in my Fujitsu Inverter Halcyon?
Weak or stopped airflow in your Fujitsu Air Conditioner can occur for various reasons: * When heating starts, fan speed is temporarily low to warm internal parts. * During heating, the outdoor unit stops and the indoor unit operates at low speed if the room temperature exceeds the thermostat setting. * The indoor unit may temporarily stop during heating for 7-15 minutes for automatic defrosting. * In dry mode, the fan operates at low speed or stops periodically to adjust humidity. * SUPER QUIET operation reduces fan speed. * In AUTO mode, the fan operates at very low speed. * For Multi-type units, differing operation modes across units can cause some to stop, indicated by a flashing green OPERATION lamp.
Why does my Fujitsu Inverter Halcyon smell?
A smell emitted from your Fujitsu Air Conditioner may be due to room odors (furniture, tobacco, etc.) that have been drawn into the indoor unit.
Why does my Fujitsu Inverter Halcyon Air Conditioner emit mist or steam?
The mist or steam emitted from your Fujitsu Air Conditioner could be due to these reasons: * During Cooling or Dry operation, a thin mist may appear because of the rapid cooling of room air, leading to condensation. * During Heating, the outdoor unit's fan might stop, and steam may rise from it due to Automatic Defrosting.

This document describes a Fujitsu Halcyon Inverter Air Conditioner, a wall-mounted unit designed to provide comfortable indoor environments through various operating modes and features.
The core function of this air conditioner is to regulate room temperature and air quality. It utilizes inverter technology, which allows it to quickly reach the desired temperature at the start of operation, then automatically switch to a lower power setting for economic and comfortable performance. This intelligent control helps maintain a consistent temperature while optimizing energy consumption.
The unit offers several operating modes to suit different needs:
The air conditioner also includes various timer functions for automated operation:
Airflow direction can be precisely controlled:
The air conditioner is primarily controlled via a Wireless Remote Controller, which allows convenient adjustment of all operating parameters from a distance of up to 23 feet (7 meters). The remote controller features:
In case the remote controller is unavailable, a MANUAL AUTO button on the indoor unit's operating control panel allows for basic AUTO mode operation.
The unit provides visual feedback through indicator lamps on the indoor unit:
Regular cleaning and care are essential for maintaining the air conditioner's performance and air quality.
For extended periods of non-use (1 month or more), it is recommended to operate the unit in fan mode continuously for half a day to dry internal parts thoroughly before shutting down the power supply. For any internal dirt accumulation or reduced performance over time, authorized service personnel should be consulted for inspection.
