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 controls for temperature adjustment
To adjust compartment temperatures:
1
  The PC compartment LED will automatically be illuminated. 
The temperature will show as a series of LEDs.
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.
4
  Use the   or   to adjust the FC temperature.
