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.

Environmental health and safety

When servicing products, consider safety and health issues
and requirements which must be adhered to at all times.
Specific safety issues are:

1 Electrical safety.
2 Electrostatic discharge.
3 Vapors while brazing.
4 Reclaiming of refrigerant.

Good practice and safety

1 Take care when removing or servicing any electrical

components to avoid electrical shock or short circuit
conditions.

2 Take care when removing plastic components at low

temperatures as breakages can occur with these
components.

3 Extreme heating of plastic components can cause distortion

of those parts being heated.

4 Avoid overheating temperature sensitive devices such as the

element thermal fuses and cabinet sensors.

5 Avoid using solvents, citrus-based cleaners on all plastic

parts. We advise only warm soapy water be used.
