Normal Operation or Malfunction of the Air Conditioner
The following items are not classed as abnormal operation or malfunction of the air conditioner and do not
require you contacting your authorised Climate Technologies service department or a service visit:
The System Does Not Start Immediately After the ON / OFF Button is Pressed
If the controller display is showing ON the system is in the normal operating condition. The system may
not start or restart immediately because one of its safety devices or timers has activated to prevent the
system from being overloaded. The system can start after at least 3 minutes has passed, in some cases
the safety delay may extend to 10 minutes depending on the previous operating function.
The System Does Not Start Immediately After Adjusting the SET TEMP
If the controller display is showing ON the system is in the normal operating condition. The system may
not start or restart immediately because one of its safety devices or timers has activated to prevent the
system from being overloaded. The system can start after at least 3 minutes has passed, in some cases
the safety delay may extend to 10 minutes depending on the previous operating function.
Starting and Stopping of the Outdoor Unit Compressor and Fan
During normal operation the outdoor unit fan may start and stop depending on the system requirements,
this may happen while the compressor is operating. The outdoor noise levels may change during the ON /
OFF operation of the outdoor fan. The compressor will start and stop as required for the heating and
cooling needs of the system.
Water Flow from the Outdoor Unit
This will most likely occur during heating operation depending on the outdoor humidity and temperature
levels. Some water may also drip from the service valves and pipe work during cooling and heating
operation.
Refrigerant Flow Sound
During starting and stopping a “shuh” sound may be heard, this is a result of the refrigerant flow.
Smells from the Indoor Unit
The unit will draw smells into the return air from furniture, rooms, cooking, etc... Ensure good ventilation
and clean the return air filter regularly to minimise smells that may result after long periods of use.
Steam or Mist from the Outdoor Heat Exchanger
During defrost operation it is likely that steam or mist may be produced off the outdoor heat exchanger
while the frost is being melted.
