1. Install the upper roof exhaust vent.
Make sure that no sawdust, insulation, or other construction
debris is on the refrigerator or in the enclosure. Debris can cause
a combustion hazard and prevent the refrigerator from operating
correctly.
Tighten the screws of the upper roof exhaust cap to 10 inch-pounds max.
Also make sure that the air fl ow around the upper roof exhaust cap is not
blocked or decreased by other roof mounted features such as a luggage
carrier, an air conditioner, a solar panel, etc.
2. Align the upper roof exhaust vent above the lower intake exhaust vent:
3. Determine the type of enclosure in a vehicle using an upper roof exhaust vent (See
Art02480):
- If the distance from the face of the enclosure to the inboard edge of the roof exhaust vent
opening [169] is more than 17 1/2 inches, install the roof exhaust vent [12] directly above
the condenser [11] of the refrigerator as a vertical enclosure.
- If the distance from the face of the enclosure to the inboard edge of the roof exhaust vent opening [169] is 17 1/2 inches or less,
install the roof exhaust vent [12] inboard from the condenser [11] of the refrigerator as an offset vertical enclosure.

Make sure that all horizontal baffl es are the full width of the inside of the
enclosure and are in the correct location. If the baffl es are not the full
width of the enclosure or incorrectly located, poor cooling performance
can result.
Vertical enclosures:
If the enclosure depth is 24 inches or more and less than 25 inches (See Art02481):
- Install a top baffl e [13].
- Make sure there is less than 1/4 inch clearance [15] between the baffl e and the top of
the refrigerator.
