SAVE THESE INSTRUCTIONS
This information is intended for use by individuals possessing adequate experience in servicing electrical, electronic and
mechanical appliances. Any attempt to repair a major appliance may result in personal injury and property damage. The
manufacturer or seller cannot be responsible for the interpretation of this information, nor can it assume any liability in
connection with its use.
ImpORTANT SAfETy INSTRUCTIONS!
!
CAUTION:
This machine must be electrically grounded. It can be grounded through the grounding lead in the 3-prong
power cord, if plugged into a properly grounded appliance outlet or through a separate No. 13 (14 gauge
(1.5 mm)) or large wire from the cabinet to an established ground. In all cases the grounding method must
comply with any local electrical code requirements. Certain internal parts are intentionally NOT GROUNDED and
may present a risk of electrical shock only during servicing. To reduce the risk of shock, disconnect the power
supply cord before servicing.
CAUTION: ALL TERmINALS AND INTERNAL pARTS SHOULD BE TREATED AS LIVE.
ImpORTANT – RE-CONNECT ALL GROUNDING DEVICES.
If grounding wires, screws, straps, clips, nuts or washers used to complete a path to ground are removed for
service, they must be returned to their original position and properly fastened.
INTERNAL LED DISpLAy INTERfACE
1
All models are fitted with an internal display which
consists of several LED indicators and several capacitive
touch buttons. Three versions of the internal display are
shown below.
Internal display for Internal display Internal display for
Tasman models for Designer and Ice & Water models
Elegance models
There are five LED indicators along the top of the display.
These are:
Key Lock Illuminated when keys are disabled.
Spanner Illuminated when a fault is detected
in the product.
Filter Illuminated when the timer for the
change
filter has expired. Only applicable to
indicator
ice & water models.
Sabbath Illuminated when Sabbath mode is
mode enabled. In this mode all other LEDs
are off and all keys are locked.
Key Mute Illuminated when key beeps are
muted.
ExTERNAL LED DISpLAy INTERfACE

Ice & Water models are fitted with an external display.
External display for Ice & Water models
There is one button with LED indicator and two LED icons
along the top of the display.
Dispenser lock Locks/unlocks the water
button and light dispenser. Light is on when
the water dispenser is locked.
Bottle Chill Indicates when 'Bottle Chill' is
on and flashes when beverage

fault codes
The icon will appear automatically if there is a fault in
the temperature measuring system, defrost system, fans or
low ambient heater. When the PC door is opened an alarm
will sound.
– The number of beeps will indicate the fault code.
– OR adding the value of illuminated LEDs will indicate
the fault code.
Fault indicated on Internal control panel
The temperature LEDs display the fault reading in a binary code.
