Cause
• This is the preliminary step to prepare for the TIMER
operation after it has been set.
When Timer is set ON, the unit may start earlier (up to
35 minutes) before the actual set time to achieve the
desired temperature on time.
• The unit is in defrost mode (and AIR SWING has been
set to AUTO).
• The system has been locked to operate in HEAT mode
only.
• When Timer has been set, the Timer setting repeats
daily.
• The delay is a protection to the unit's compressor.
• The lowest fan speed is to have a low noise operation,
so cooling/heating capacity may be reduced depending
on the condition. Increase the fan speed to increase the
capacity.
• To avoid unintended cooling effect.
• This is to help remove the surrounding odour.
• To extract the remaining heat from the indoor unit
(maximum 30 seconds).
• This may be due to damp smell emitted by the wall,
carpet, furniture or clothing.
• Changes in temperature caused the unit to expand and
contract.
• Refrigerant fl ow inside the unit.
• During cooling operation, the discharged cold air may
condense to water vapour.
• During cooling operation, condensation occurs on
cold pipes and the condensed water may drip from the
outdoor unit.
• Discoloration is subjected to the types of materials
used in plastic parts. It is accelerated when exposed to
heat, sun light, UV light or environmental factors.
Check
• Set the temperature correctly.
• Close all doors and windows.
• Clean or replace the fi lters.
• Clear any obstruction at the air inlet and air outlet
vents.
• Check if the unit has been installed at an incline.
• Close the front panel properly.
• Insert the batteries correctly.
• Replace weak batteries.
• Check if the circuit breaker is tripped.
• Check if timers have been set.
• Make sure the receiver is not obstructed.
• Certain fl uorescent lights may interfere with the signal
transmitter. Consult an authorised dealer.
