Safety precautions
ELECTRICAL
• Push the moulded plug into a 15A. 230V earthed wall socket. ( 9K and 12K models only. Larger
models require a dedicated connection to the mains.)
• Do not pull on the power cord.
• Do not use an adaptor plug to operate another appliance from the same wall socket.
• Do not make joints in the power cord.
• A frayed or damaged power cord must be replaced by a qualified electrician.
• Ensure that the wall socket is accessible should you need to remove the plug.
• Should anything abnormal occur, such as a burning smell or smoke, switch off the power supply at
the mains immediately and remove the plug from the wall socket. Call the nearest Defy Service centre for assistance.
INSTALLATION
• Do not install the air conditioner in places where a gas leak could occur.
• Do not use the air conditioner to control the temperature of specialised areas such as cold rooms or
chemical storage facilities.
• Do not place fuel burning appliances directly in the air flow. Incomplete combustion or flame failure
could result.
OPERATION
• In high humidity conditions ( 80% and above) and while operating the unit in COOL/DRY mode
some condensate or moisture may drip from the unit. To avoid this it is recommended that windows
and doors remain closed. Should the room become too stuffy, briefly open a door or window to let
some fresh air into the room.
GENERAL
• Do not spray insecticide on the air conditioner.
• Do not insert any object or body part into the outlet / inlet grille. The high speed fan could be dam-
aged or cause injury.
Maintenance
CLEANING THE FRONT AIR FILTERS
• The air filters must be cleaned regularly to ensure optimum performance.
• Switch the air conditioner off and unplug at the wall socket.
• Open the front grille by pulling the tabs on either side and hinging the grille upwards until it clicks
into the open position.
• Remove any accumulated dust from the grille and filters using a vacuum cleaner or brush. If neces-
sary the filters may be washed in soapy warm water. (below 45°C).Rinse in clean water and allow to
dry in the shade.
• Re-fit the filters and lower the front grille.
• Clean the surface of the air conditioner with a damp soapy cloth and wipe dry.
• Do not clean the air conditioner with chemical solvents, abrasive cleaners or flammable liquids.

Trouble shooting continued
FAULT
The indoor fan stops working during heating. The air conditioner is de-icing and will resume normal
operation after about 10 minutes.
A cracking sound may be heard. Friction sounds resulting from the expansion and contrac-
tion of the front grille during temperature changes may be
the cause.
Sounds like running water may be heard This is normal and could be the sound of refrigerant flow-
ing in the system, or defrost water melting from the heat
exchanger.
The indoor unit makes a clicking and swoosh
sound
The air distribution vane stops swinging for
some 3 minutes at a time.
The outdoor unit appears to leak water. There will be some water visible during cooling or heat-
The click is the compressor switching on and off. The
swoosh is caused by refrigerant being released in the system.
This is designed to prevent water condensation and is normal
ing resulting from condensation or defrost water.
