- Make sure that the back of the solid box baffle is perpendicular to the bottom of the
enclosure.
- Make sure that the back of the solid box baffle is either against the top of the enclosure or
against the angled baffle [13] (depending on the vehicle design).
- Make sure that the solid box baffle is one inch or less [19] from the coils [10] and
condenser of the refrigerator.
- Make sure that the solid box baffle is the full width of the inside of the enclosure.
- If the design of the vehicle does not allow you to install a roof exhaust vent, install an upper
side-wall exhaust vent.
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]. N61X models are 47.1 in. min. to 47.4 in. max.
from the bottom of the refrigerator to the bottom of the refrigerator condenser
[23]. N81X models are 54.1 in. min. to 54.4 in. max. from the bottom of the
refrigerator to the bottom of the refrigerator condenser [23] (See Art01601).
Only use an upper side-wall exhaust vent on refrigerator models
that are equipped with a fan. If you use an upper side-wall exhaust
vent on a refrigerator model that is not equipped with a fan, the
refrigerator cooling performance will be poor.
- Make sure the refrigerator model is equipped with a fan.
- Install the upper side-wall exhaust vent [24] (See Art01592 and Art01593).
- For N61X models, make sure the distance [25] from the bottom of the enclosure to
the top of the rough opening for the upper exhaust vent is at least 55 inches.
- For N81X models, make sure the distance [25] from the bottom of the enclosure to the top of the rough opening for the
upper exhaust vent is at least 62 inches.
- Align the upper exhaust vent [24] horizontally above the lower
intake vent [9] of the refrigerator.
- To prevent stagnant hot air in the area above the refrigerator,
install an aluminum or galvanized steel sheet baffle [13]
between the top of the refrigerator and the top of the upper
exhaust vent.
- Make sure there is less than 1/4 inch clearance between
the baffle and the top of the refrigerator and that the
baffle overlaps the refrigerator 1 inch or less.
- Make sure that the baffle is against the wall of the
vehicle at the top of the upper exhaust vent and 1/4 inch
or less from the top of the opening for the upper exhaust
vent [15].
- Make sure the baffle is the full width of the inside of the
enclosure.
- When using an upper side-wall exhaust vent:
- If the depth of the enclosure is 24 inches or more and is less than
26 inches [27], install a bent aluminum or galvanized steel sheet
baffle [26] to the rear of the enclosure (See Art01592).
