Internal controls for temperature adjustment
To adjust compartment temperatures:
1 The PC compartment LED will automatically be illuminated.
Important safety instructions!
The temperature will show as a series of LEDs.
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.
2 Use the or to adjust the PC temperature.
3 To adjust the FC compartment temperature press the
button once so the FC compartment LED is illuminated.

Take care when removing plastic components at low
temperatures as breakages can occur with these
components.
Extreme heating of plastic components can cause distortion
of those parts being heated.
Avoid overheating temperature sensitive devices such as the
element thermal fuses and cabinet sensors.
Avoid using solvents, citrus-based cleaners on all plastic
parts. We advise only warm soapy water be used.
