Assemble the Enclosure for the Refrigerator 1. Make sure the enclosure shelf is solid and level. The enclosure shelf must be: 174 - a metal or a wood panel and extend the full width and depth of the enclosure. - able to support the weight of the refrigerator and its contents. - level to maintain door alignment. 2. Make sure there are no adjacent heat sources such as a furnace vent, a hot water heater vent, etc. 3. Make sure the enclosure is 63.25 - 63.38 inches high x 32.69 - 32.
Optional Installation You can change enclosures that were made for Norcold model N8XX refrigerators so that you can put Norcold model 121X refrigerators into them. To change the Norcold model N8XX refrigerator enclosure [130] into the Norcold model 121X refrigerator enclosure [131] (See Art01597): - Increase the height of the enclosure by 3 3/8 inches [132]. - Increase the width of the enclosure by 8 13/16 inches [133].
Install an Upper Roof Exhaust Vent 1. Install the upper roof exhaust vent. 169 CAUTION: Make sure that no sawdust, insulation, or other construction debris is 12 on the refrigerator or in the enclosure. Debris can cause a combustion hazard and prevent the refrigerator from operating correctly. NOTE: Tighten the screws of the upper roof exhaust cap to 10 inch-pounds max.
If the enclosure depth is 25 inches or more and less than 26 inches (See Art01781): - Install a top baffle [13]. 15 13 - Make sure that the top baffle is less than 1/4 inch [15] from the top of the refrigerator. - Install a condenser baffle [16] at the lowest edge of the condenser of the refrigerator. 19 - Make sure that the condenser baffle is 1 inch or less [19] from the condenser.
Offset vertical enclosures: 15 If the enclosure depth is 24 inches or more and less than 25 inches (See Art01783): 172 - Install an angled top baffle [172] between the top rear edge of the refrigerator and the inside edge of the upper exhaust vent opening. 20 172 - Make sure that the angled top baffle is less than 1/4 inch [15] from the top of the refrigerator. - Make sure that the angled top baffle is no more than 45° from vertical [20].
If the enclosure depth is 26 inches or more (See Art01785): 14 172 - Install an angled top baffle [172] between the top rear edge of the refrigerator and the inside edge of the upper exhaust vent opening. - Make sure that the angled top baffle is less than 1/4 inch from the top of the refrigerator. 173 20 11 - Make sure that the angled top baffle is no more than 45° from vertical [20].
Install an Upper Side-Wall Exhaust Vent 22 If the design of the vehicle does not allow you to install a roof exhaust vent, install an upper sidewall exhaust vent. NOTE: The refrigerator is 23.7 in. min. to 24.0 in. max. from the rear of the breaker to the rear of the condenser [22] and is 59.0 in. min. to 59.3 in. max. from the bottom of the refrigerator to the bottom of the refrigerator condenser [23] (See Art01600).
- Make sure that the bend of the condenser baffle is flush with the bottom edge of the door frame of the upper side-wall exhaust vent. 13 15 15 15 11 - Make sure that the top edge of the condenser baffle is 1/4 inch or less [15] from the lower rear corner of the condenser. If the enclosure depth is 26 inches or more (See Art01787): - Install a wood, aluminum or galvanized steel top baffle [13] between the top of the refrigerator and the top of the upper exhaust vent [24].
Install an Air Deflector (optional) If the floor plan has the refrigerator on the rear wall of the vehicle, obey all of the vent installation as written in the “Install the Lower and Upper Vents” section of this manual. Install the roof exhaust vent so that: 175 176 24 - The sloped end of the roof exhaust vent is toward either side of the vehicle. - The roof exhaust vent is perpendicular to the air flow over the vehicle.
Install the Refrigerator When manually (by hand) or mechanically (by hoist , lift truck, etc.) handling a refrigerator that is not installed in an enclosure, the best method is while the refigerator is in it’s original packaging. 122 If the refrigerator is not in its original packaging, use the sides, the edges, and/or the corners of the refrigerator cabinet as the primary load carrying points. There are two (2) areas of the cooling unit that may be used as handling points [122] (See Art01754).
2. Make sure that the side trim pieces [127] are in the correct position (See Art01649 and Art01650): 127 41 129 40 127 - Slide both side trim pieces up or down as necessary so that the ends of the side trim pieces are fully covered by the upper and lower trim pieces [40 and 128]. - Pull the left hand side trim piece toward the left as far as it will go so that there is no gap between the edge of the side trim piece and the upper and lower trim pieces.
Connect the Electrical Components This refrigerator operates on these electrical sources. Operation out of these limits may damage the refrigerator’s electrical circuit parts and will void the warranty. AC Operation 120 volts AC voltage 12 volts DC control voltage (132 volts max. - 108 volts min.) (15.4 volts max. - 10.5 volts min.) WARNING: The rear of the refrigerator cooling system has hot surfaces and sharp surfaces that can damage electrical wiring.
Connect the Propane Gas Components This refrigerator operates on propane gas at a pressure of 11 inches Water Column Propane. The controls operate on 12 volts DC (10.5 volts min. - 15.4 volts max.). Operation out of these limits can damage the refrigerator electrical circuit parts and will void the warranty. Connect the propane gas supply system: WARNING: Be very careful when working on or near the propane gas system. - Do not smoke, or use an open flame near the propane gas system.
Connect the Ice Maker (optional) The ice maker is assembled to the refrigerators at the factory as optional equipment. If the refrigerator does not have a factory installed ice maker, one can not be added to the refrigerator at a later time. The refrigerator installer must connect a cold water supply line to the solenoid valve at the rear of the refrigerator. The following are necessary to connect the icemaker: - 1/4 in. OD copper tubing for the water supply line. OR - 1/4 in.
Ignition and Start Up Before ignition or start up of the refrigerator: - Make sure the air flow in the lower intake vent, through the refrigerator coils and condenser, and out the upper exhaust vent is not blocked or decreased. - Make sure there are no combustible materials in or around the refrigerator. NOTE: If the gas does not ignite in 30 seconds, the gas safety valve of the refrigerator automatically closes.
- If a less efficient energy source is not available: - An audible alarm starts. - A fault code shows in the center display. - Refer to the “Fault Codes” section of this manual. Set the controls to manual mode operation: - Push the ON / OFF button to turn the refrigerator on. - Push and hold the MODE button until the letters “ AC” show in the center display and then release. - After ten seconds, the “AC” goes off and only a green power ON light remains.
