SAFETY INFORMATION
Under NO circumstances should any service work be carried out unless you are qualified and licensed as per Federal, State
and Territory requirements.
General Safety
•Work should not be under taken on any electrical appliance without first checking the earthing integrity of the appliance
and electrical supply.
•A safety audit should be carried out of the work area to ensure the area has adequate room to work in and is free from
any hazards that may cause any injury to yourself and any other person in the vicinity.
•After repair, product has to be reassembled as it was which complies with specification of the Manufacturer to ensure
product is safe to operate both mechanically and electrically.
Electrical Safety
•Under NO circumstances should changing or repairs to parts be carried out on live appliances. Any changing or repair
to parts must be done with the appliance removed from the electrical supply. Failure to do so may result is injury or
death.
•After any work is completed the earthing integrity of the appliance must be checked.
•If you need to do electrical testing with the product live the following must be observed:
oIt must be on a circuit with earth leakage protection.
oAs much skin as possible should be covered to reduce the chances of coming into contact with live terminals
oAll jewellery should be removed.
oThere should not be any water/moisture on the ground.
oA safety sign should be displayed to warn others of the danger.
Running appliances with panels/covers removed
•All the electrical safety procedures above must be observed.
•Care must be taken not to come into contact with moving parts.
•Loose clothing or jewellery that can become entrapped should not be worn.
•If handling or working near sharp edges the appropriate personal protection equipment must be used.
•Safety eyewear should be used if removing parts that may “spring and fly” if they slip of a tool. Eg removing a spring
which is under compression.
•Any removed panels that have sharp edges should be placed where they do not cause any danger of injury to yourself
or others.
•A safety sign should be displayed to warn others of the danger.
•If handling or working in a dusty area or with Dust Product, dust mask or appropriate PPE should be used.
Refrigeration
•Ensure you know which refrigerant is in the appliance so the correct gas handling procedures can be used. Failure to
use the correct procedure may result in injury.
•If hot work needs to be done ensure all the surround area is safe and free from combustibles. Where necessary heat
shielding should be used.
•Ensure pipework has cooled down before touching.
•When handling gas make sure all necessary PPE is used.
•Ensure there is enough ventilation.
•Place warnings signs so others know flames/smoking must not be in the area.
Gas Safety
•Under no circumstances should a naked flame be used, eg match, lighter etc, to try and find a gas leak, only an
appropriate gas leak detector or soapy water should be used.
•When converting an appliance to another gas type, the gas type label supplied must be fitted in the appropriate area.
•Always ensure the product is connected to the correct gas type.
•When working with a gas leak place warnings signs so others know flames/smoking must not be in the area.
•After fixing a gas leak do not try and ignite the burner(s) until any remaining escaped gas has dissipated.

•For all models: Power ON by pressing the On/Off button and continue to press the Start/Stop button for at
least 6 seconds.
•When “Service test” is shown:
For models without a display: All LEDs are ON. If the model has a sliding dispenser, all LEDs blink three
times and the service test starts.
For models with a display: All LEDs are ON, “SP”is shown on the display and the service test starts.
During the first 6 seconds of the test, if a failure code is stored in its memory, its code blinks. Also at the
end of the test - if an error occurs its error code blinks.
During the test, “SP”is shown.
