OM-40MAHB-01 Specifications subject to change without notice. 9
FEATURES
The unit provides the following features for added comport and safety.
Time Delay
If ON/OFF is pressed too soon after a stop, the compressor will not
start for 3 to 4 minutes due to the inherent protection against frequent
compressor cycling. The unit only emits an audible beep when the
signals are received correctly.
Heating
If the unit is in HEATING mode, there is a delay when the fan starts.
The fan starts only after the coil is warmed up to prevent cold blow.
Auto Defrost Operation
In the HEATING mode, if the outdoor coil is frosted, the indoor fan
and outdoor fan turns off while the system removes the frost on the
outdoor coil. The system automatically reverts to normal operation
when frost is removed from the outdoor unit.
Auto Start
If the power fails while the unit is operating, the unit stores the
operating condition, and it will start operation automatically under
those conditions when the power is restored.
Auto-Restart (some units)
If the unit loses power, it automatically restarts with the prior settings
once power has been restored.
Anti-mildew (some units)
When turning off the unit from COOL, AUTO (COOL), or DRY
modes, the air conditioner continues to operate at very low power to
dry up any condensed water and prevent mildew growth.
Wireless Control (some units)
Wireless control allows users to control the air conditioner using a
mobile phone and a wireless connection. For the USB device access,
replacement, maintenance operations must be carried out by
professional staff.
Louver Angle Memory (some units)
When turning on the unit, the louver automatically resumes its former
angle.
Active Clean (some units)
The Active Clean Technology washes away dust, mold, and grease
that may cause odors when it adheres to the heat exchanger by
automatically freezing and then rapidly thawing the frost. The
operation produces more condensed water to improve the cleaning
effect.
After cleaning, the blower wheel keeps operating with hot air to blow-
dry the evaporator, thus preventing the growth of mold and keeping
the inside clean. When this function is turned on, the indoor unit
window displays CL. After 20 to 45 minutes, the unit turns off
automatically and cancels the function.
Breeze Away (some units)
This feature avoids direct air flow from blowing on inhabitants.
Refrigerant Leak Detection (some units)
The indoor unit automatically displays EL0C when it detects
refrigerant leakage.
Occupancy Sensor (some units)
The system is controlled intelligently under the Occupancy Sensor
mode. The feature detects the movement in the room. In COOLING
mode, when occupants are away for 30 minutes, the unit automatically
lowers the frequency to save energy (for Inverter models only). And
the unit automatically starts and resumes operation when movement is
detected.
Resetting the Remote Control
If the batteries in the remote control are removed, the current settings
cancel and the control returns to the initial settings and enters the
STANDBY mode. Push ON/OFF to activate.
NOTE: For multi-zone air conditioners, the following functions
are not available: ACTIVE CLEAN, SILENCE, BREEZE AWAY,
REFRIGERANT LEAKAGE DETECTION and ECO.
Setting Vertical Angle of Air Flow
While the unit is on, press SWING on the remote control to set the
direction (vertical angle) of airflow.
NOTE: When using the COOL or DRY mode, do not set the
louver at too vertical an angle for long periods of time. Doing so
can cause water to condense on the louver blade, which may drop
on your floor or furnishings.
When using the COOL or HEAT mode, setting the louver at too
vertical an angle can reduce the performance of the unit due to
restricted air flow.
Setting Horizontal Angle of Air Flow
The horizontal angle of the airflow must be set manually. Grip the
deflector rod (see Fig. 11 — on page 10) and manually adjust it to
your preferred direction. For some units, the horizontal angle of the
airflow can be set by remote control.
