Manual Operation and Maintenance
Operation mode selection
While two or more indoor units are simultaneously operating,
make sure the modes do not conflict with each other. The
heat modes 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 try 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 of a customer service centre if
the unit requires.
NOTE
: Before you clean the air conditioner, be sure to
switch off the unit and disconnevy 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 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 0ºC (32ºF),
it is strongly recommended that you to keep the machine
plugged in so as to guarantee smooth operation.
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.
