Operation mode selection
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 initially started to operate in HEAT mode, the
other units can operate in HEAT mode only. For
example: If the unit initially 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 display ”--” (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) will light up,
or the operation indication light will flash rapidly,
and the timer indication light will turn off ( for
the floor and standing type).
Maintenance
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 components of the outdoor unit
periodically. Contact a local dealer or a
customer service center if the unit requires
servicing.
NOTE:
Before you clean the air conditioner, be
sure to switch off the unit and disconnect the
power supply plug.
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 performance may be
reduced.
•
Do not operate unit with horizontal louvre in
closed position.
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.
•
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.
