for personal injury. There are 3 levels of precaution:
1. DANGER identifies the most serious hazards which will result in
severe personal injury or death.
2. WARNING signifies hazards that could result in personal injury or
death.
3. CAUTION is used to identify unsafe practices which could result in
minor personal injury or product and property damage.

GENERAL
The high wall fan coil unit provides quiet, maximum comfort. In addition
to cooling and/or heating, the high wall fan coil unit matched with an
outdoor condensing unit filters and dehumidifies the air in the room to
provide maximum comfort.
IMPORTANT: The high wall fan coil unit should be installed by
authorized personnel only; using approved tubing and accessories. If
technical assistance, service or repair is needed, contact the installer.
The high wall fan coil unit can be set up and operated from the
remote control (provided). If the remote is misplaced, the system can
be operated from the “Auto” setting on the unit.
Operating Modes:
The high wall fan coil unit has five operating modes:
• FAN Only
• AUTO
• HEATING (heat pumps only)
•COOLING
• DEHUMIDIFICATION
FAN Only
In the FAN Only mode, the system filters and circulates the room air
without changing room air temperature.
AUTO
In the AUTO mode, the system automatically cools or heats the room
according to the user-selected set point.
NOTE: AUTO mode is recommended for use on single zone
applications only. Using AUTO changeover on multi-zone
applications could set an indoor unit to STANDBY mode,
indicated by two dashes (--) on the display, which turns the
indoor unit off until all the indoor units are in the same
mode; either COOLING or HEATING.
NOTE: HEATING is the system’s priority mode. Simultaneous
HEATING and COOLING is not allowed.
HEATING
In the
HEATING
mode, the system heats and filters the room air.
COOLING
In the COOLING mode, the system cools, dries and filters the room air.
DEHUMIDIFICATION (DRY)
In DEHUMIDIFICATION mode, the system dries, filters and slightly
cools the room air temperature. This mode prioritizes air
dehumidification but it does not take the place of a dehumidifier.
AUTO LEAK DETECTION
AUTO LEAK DETECTION SYSTEM installed. Unit must be powered
except for service. For the unit with refrigerant sensor, when the
refrigerant sensor detects refrigerant leakage, the indoor unit will display
a error code and emit a buzzing sound, the compressor of outdoor unit
will immediately stop, and the indoor fan will start running. The service
life of the refrigerant sensor is 15 years. When the refrigerant sensor
malfunctions, the indoor unit will display the error code FHCC. Refer to
the error code table in the unit’s service manual for details. The
refrigerant sensor can not be repaired and can only be replaced by the
manufacture. It shall only be replaced with the sensor specified by the
manufacture.
