Installation Manual 10
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 23.75 in. min. to 24.05 in. max. from the rear of the breaker
to the rear of the condenser [22] and is 61.35 in. min. to 61.65 in. max. from
the bottom of the refrigerator to the bottom of the refrigerator condenser [23]
(See Art02487).
- Install the upper side-wall exhaust vent [24] so that the distance [25] from the bottom of
the enclosure to the top of the rough opening for the upper exhaust vent is at least 71.0
inches (See Art02487 and Art02488).
- Align the upper exhaust vent horizontally above the lower intake vent [9].
Install an Upper Side-Wall Exhaust Vent
If the enclosure depth is 26 inches or more (See Art02486):
- Install an angled top baffl e [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 baffl e is less than 1/4 inch from the top of the
refrigerator.
- Make sure that the angled top baffl e is no more than 45° from vertical [20].
- Install an inside corner baffl e [173] between the outside edge of the upper exhaust
vent opening and the solid box baffl e.
- Make sure that the inside corner baffl e is approximately parallel to the angled top
baffl e.
- Install a wood or an aluminum or galvanized sheet solid box baffl e [21] in the rear of
the enclosure.
- Make sure that the bottom of the solid box baffl e is 21 inches to 21 1/2 inches
above the bottom of the enclosure [17] (7 1/4 inches to 7 3/4 inches above the
top of the lower intake vent opening) [18] .
- Make sure that the back of the solid box baffl e is perpendicular to the bottom of
the enclosure.
- Make sure that the back of the solid box baffl e is either against the top of the
enclosure or against the inside corner baffl e [173] (depending on the vehicle
design).
- Make sure that the solid box baffl e is one inch or less from the coils [10] and
condenser [11] of the refrigerator.
- Make sure that the solid box baffl e is the full width of the inside of the
enclosure.
