Operation mode selection
Maintenance
While two or more indoor units are
simultaneously operating, make sure the modes
do not conflict with each other. The heat mode
claims precedence over all other modes. If the
unit intially started to operate in HEAT mode, the
other units can operate in HEAT mode only. For
example: If the unit intially started operates under
COOL (or FAN) mode, the other units can operate
under any mode except HEAT. If one of the unit
selects HEAT mode, the other operating units will
stop operation and diplay ”--” (for units with
display window only) or the auto and operation
indication light will flash rapidly, the defrost
indication light will turn off, and the timer
indication light will remain on (for units without
a display window). Alternatively, the defrost and
alarm indication light (if applicable) wil light up,
or the operation indication light will flash rapidly,
and the timer indication light will turn off ( for
the floor and standing type).
If you plan to leave the unit idle for a long time,
perform the following tasks:
1. Clean the indoor unit and air filter.
2. Select FAN ONLY mode and let the indoor fan
run for a time to dry the inside of the unit.
3. Disconnect the power supply and remove the
battery from the remote control.
4. Check the components of the outdoor unit
periodically. Contact a local dealer or a
customer service centre if the unit requires
servicing.
When the air conditioner is to be used
again:
• Use a dry cloth to wipe off the dust
accumulated on the rear air intake grille in order
to avoid the dust being dispersed from the
indoor unit.
• Check that the wiring is not broken off or
disconnected.
• Check that the air filter is installed.
• Check if the air outlet or inlet is blocked after
the air conditioner has not been used for a long
time.
Suggestion:
For units that feature an electric heater,
when the outside ambient temperature is
below 0°C (32°F), it is strongly recommended
that you to keep the machine plugged in so
as to guarantee smooth operation.
Optimal operation
To achieve optimal performance, please note the
following:
• Adjust the direction of the air flow so that it is
not blowing directly on people.
• Adjust the temperature to achieve the highest
possible level of comfort. Do not adjust the
unit to excessive temperature levels.
• Close doors and windows in COOL mode or
HEAT mode.
• Use the TIMER ON button on the remote
controller to select a time you want to start
your air conditioner.
• Do not place any object near the air inlet or air
outlet, as the efficiency of the air conditioner
may be reduced and the air conditioner may
stop running.
• Clean the air filter periodically, otherwise
cooling or heating per formance may be
reduced.
• Do not operate unit with horizontal louvre in
closed position.
NOTE: Before you clean the air conditioner, be
sure to switch off the unit and disconnect the
power supply plug.
