SYSTE FUNCTIONS
WHISPER QUIET
Not only are the Gree systems energy efficient but they are quiet too. Mini- loor Console
operates with sound levels starting as low as 33 dB(A).
ULTI FAN SPEEDS
Whether operating in either Cooling or Heating mode, the indoor fan can be set to your choice
of three different speeds (Low, Medium or High) to achieve maximum comfort.
INTELLIGENT PRE-HEATING
Multi21 Systems guard against the annoying cool air blown into the room in heating mode.
The system constantly monitors the discharge air temperature. It will delay the indoor fan until
the indoor coil has warmed up to prevent blowing uncomfortable cool air into the room.
WIRELESS RE OTE
The Gree multi-functional infrared hand held wireless controller is sleek, ergonomically
designed, easy to use and has a large backlit LCD display.
INTELLIGENT DEFROST
The Intelligent Defrost function increases room comfort and saves energy by eliminating
unnecessary defrost cycles. In heating mode, the unit will monitor the outdoor coil for frost
buildup. Once frost buildup has been detected, the system will switch into a defrost mode to
remove the frost.
I FEEL ODE
The unit will sense room temperature at the remote controller instead of at the indoor unit
during Cooling Mode. It then adjusts airflow and temperature accordingly for the ultimate in
personal comfort control and energy savings.
SWING LOUVER
The adjustable swing louvers can be controlled from the wireless controller. Vertical swing
louvers allows five different air discharge directions including Continuous Sweep. Maximize
comfort by adjusting the direction of airflow in the room by moving the louvers up or down.
POWER FAILURE ODE
Power interruptions are no problem for the Multi21 system. User selections and system
parameters are stored in non-volatile memory. These parameters are retained during a power
failure. When power is returned, the Mini- loor Console system will automatically return to
the last operating mode.
CLOCK
The wireless remote controller has a built-in clock feature. The remote
will display the time of day in a 24-hour format.

not adjustable. The system will automatically select heating or cooling to maintain room
temperature within this band.
SLEEP ODE
The Mini- loor Console offers three selectable Sleep Modes for your comfort. The unit will
automatically adjust room temperature during your sleep time. This slight change in
temperature will not affect your comfort level due to the natural effects that sleeping has
on the body, but it will save on energy consumption and will lower electric bills.
X-FAN ODE
When operating in humid areas, the X-fan or Dry Coil function allows the indoor fan to run for
a pre-determined amount of time after the unit is turned off (cooling or dry modes) to ensure
that additional moisture is removed from coil.
FAHRENHEIT °F / CELSIUS °C
The remote controller can be set to display in either ° or °C.
SELF-DIAGNOSIS
With an on-board computer using real-time diagnostics, the Gree Multi21 system helps to
prolong its own life. The automatic diagnosis feature continuously scans for unacceptable
operating conditions or malfunctions. If such conditions occur, the system takes corrective action
or stops. Error codes are shown on the unit display to facilitate easy troubleshooting and repair.

TROUBLESHOOTING
PROBLE
System does not restart.
Indoor unit emits unpleasant odor
when started
You hear a“water flowing”sound.
A thin fog or vapor coming out
of the discharge register when
system is running.
You hear a slight cracking sound
when the system stops or starts.
The system will not run.
The unit is not heating or cooling
adequately.
CAUSE/SOLUTION
Cause: The system has a built-in three-minute delay to prevent short and/or rapid
cycling of the compressor.
Solution: Wait three minutes for the protection delay to expire.
Cause: Typically unpleasant odors are the result of mold or mildew forming on
the coil surfaces or the air filter.
Solution: Wash indoor air filter in warm water with mild cleaner. If odors persist,
contact a qualified service professional to clean the coil surfaces.
Cause: It is normal for the system to make“water flowing”or“gurgling”sounds
from refrigerant pressures equalizing when the compressor starts and stops
Solution: The noises should discontinue as the refrigerant system equalizes after
two or three minutes.
Cause: It is normal for the system to emit a slight fog or water vapor when
cooling extremely humid warm air.
Solution: The fog or water vapor will disappear as the system cools and
dehumidifies the room space.
Cause: It is normal for the system to make “slight cracking” sounds from parts
expanding and contracting during system starts and stops.
Solution: The noises will discontinue as temperature equalizes after 2 or 3 minutes.
Cause: There are a number of situations that will prevent the system from running.
Solution: Check for the following:
• Circuit breaker is “tripped” or “turned off.”
• Power button of controller is not turned on.
• Controller is in sleep mode or timer mode.
• Otherwise, contact a qualified service professional for assistance.
Cause: There are a number of reasons for inadequate cooling or heating.
Solution: Check the following:
• Remove obstructions blocking airflow into the room.
• Clean dirty or blocked air filter that is restricting airflow into the system.
• Seal around door or windows to prevent air infiltration into the room.
• Relocate or remove heat sources from the room.

TROUBLESHOOTING
PROBLE
Water leaking from the indoor
unit into the room.
The unit will not deliver air.
CAUSE/SOLUTION
Cause: While it is normal for the system to generate condensate water in
cooling mode, it is designed to drain this water via a condensate drain system
to a safe location.
Solution: If water is leaking into the room, it may indicate one of the following.
• The indoor unit is not level right to left. Level indoor unit.
• The condensate drain pipe is restricted or plugged. All restrictions must
be removed to allow continuous drainage by gravity.
• If problem persists, contact a qualified service professional for assistance.
Cause: There are a number of system functions that will prevent air flow.
Solution: Check for the following:
• In heating mode, the indoor fan may not start for three minutes if the
room temperature is very low. This is to prevent blowing cold air.
• In heat mode, if the outdoor temperature is low and humidity is high,
the system may need to defrost for up to 10 minutes before beginning
a heating cycle.
• In dry mode, the indoor fan may stop for up to three minutes during
the compressor off delay.
• Otherwise, you should contact a qualified service professional for
assistance.
