Important Safety Information • The use of improper rated fuses can lead to an electrical fire. In the event of a circuit overload, replace blown fuses with a fuse specified by Norcold. Fuse specifications are found in the "Specifications" section on page 2 of this manual. The correct fuse size is printed adjacent to the fuse on the refrigerator. WARNING Read this information before attempting to perform service on this refrigerator. Page 8 shows a wiring pictorial and diagram.

stitution will void the agencies’ certifications and the Norcold warranty. Refer to this manual for proper instructions. Install the refrigerator and vents as directed by Norcold without modification. Intake Pipe max. length 16" The clearance from the refrigerator’s left side (facing the front of the refrigerator) to the vehicle’s exterior wall is important. This is the area in which the inlet and outlet flexible piping will be connected to the vent terminal housing during installation.
Insulating the Flexible Exhaust Piping power cord to the receptacle. Place the "O" rings onto the ends of both flexible pipes. Bend the flexible pipes so they clear the top of the enclosure. Connect the piping as follows: The flexible exhaust pipe must be insulated prior to installation into the vent terminal housing. The flexible exhaust pipe connects to the flue tube of the refrigerator’s cooling unit and routes to the bottom opening of the vent terminal housing.
Check Out of Flame Failure Safety Device flame safety device will automatically close (an audible click will be heard as this device closes). 4. Turn the gas on at the manual shut-off valve. 5. Attempt to light the burner by placing the mode selection button to the gas mode. Do not push in the safety valve. 6. Without holding the safety valve in, the burner flame will not re-light. This indicates the flame failure safety device is functioning. 1.
Lighting and Start-Up Instructions A B C E D G F Figure 8 The Lighting and Start-Up Instructions are located on the top portion of the interior door liner. Refer to Figure 8 for location of the operating controls. Notice: When warm humid weather conditions are observed, operate the refrigerator on either AC or DC electric for a minimum of five (5) minutes before attempting to follow the Start-Up Instructions for Gas operation. 3.

Diagnosing Cooling Problems Read this information before attempting to perform service on this refrigerator. Understand the service procedures before performing the service. See pictorial and trouble shooting guide on pages 17 & 18. 4. An off-level situation, if the infraction is marginal, will allow the refrigerator to continue to operate at a reduced level of cooling until the refrigerator is leveled. Greater off-level situations will stop the refrigerant circulation and cease cooling.
