Installation Manual 5
- Put one baffle 18 inches to 18 1/2 inches above the
bottom of the enclosure [26] (4 1/4 inches to 4 3/4
inches above the top of the lower intake vent opening
REF) [27] .
- Put the other baffle at the lowest edge of the condenser
[3] of the refrigerator.
- Make sure that the baffles are 1 inch or less [28]
from the coils [2] and condenser of the refrigerator.
- Make sure that the baffles are the full width of the
inside of the enclosure.
- If the depth of the enclosure is more than 26 inches, install
a wood or an aluminum or galvanized sheet solid box baffle
[25] in the rear of the enclosure (See Art01617 and
Art01618).
- Make sure that the bottom of the solid box baffle is 18
inches to 18 1/2 inches above the bottom of the
enclosure [26] (4 1/4 inches to 4 3/4 inches above the
top of the lower intake vent opening REF) [27] .
- 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 [8] (depending on the vehicle design).
- Make sure that the solid box baffle is one inch or
less [28] from the coils [2] and condenser of the
refrigerator.
- Make sure that the solid box baffle is the full width
of the inside of the enclosure.
- If there is more than 1/2 inch of clearance between either
side of the refrigerator and the wall, fill the space with
fiberglass insulation or add a baffle to eliminate the excess
clearance.
- If the design of the vehicle does not allow you to install a
roof exhaust vent, install an upper side-wall 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
[11].
N62X, N62XXX, N64X, N64XXX, N64XIM, and
N64XIMXX models are 48.7 in. min. to 49.0 in. max.
from the bottom of the refrigerator to the bottom of
the refrigerator condenser [12].
N82X, N82XXX, N84X, N84XXX, N84XIM, and
N84XIMXX models are 55.7 in. min. to 56.0 in. max.
from the bottom of the refrigerator to the bottom of
the refrigerator condenser [12] (See Art01601).
CAUTION: 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 refrigera-
tor model that is not equipped with a fan, the refrigera-
tor cooling performance will be poor.
- Make sure the refrigerator model is equipped with a
fan.
- Install the upper side-wall exhaust vent [13] (See
Art01592 and Art01593).
- For N62X, N62XXX, N64X, N64XXX, N64XIM, and
N64XIMXX models, make sure the distance [14]
from the bottom of the enclosure to the top of the
rough opening for the upper exhaust vent is at
least 55 inches.
- For N82X, N82XXX, N84X, N84XXX, N84XIM, and
N84XIMXX models, make sure the distance [14]
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 [13] horizontally above
the lower intake vent [1] of the refrigerator.
- To prevent stagnant hot air in the area above the
refrigerator, install an aluminum or galvanized
steel sheet baffle [15] between the top of the
refrigerator and the top of the upper exhaust vent.
- Make sure there is less than 1/4 inch clear-
ance between the baffle and the top of the
refrigerator and that the baffle overlaps the
refrigerator 1 inch or less [16].
- 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 [17].
- Make sure the baffle is the full width of the
inside of the enclosure
- Make sure the clearance at the sides of the refrigerator is
correct:
- If there is more than 1/2 inch of clearance between
either side of the refrigerator and the wall, fill the space
with fiberglass insulation or add a baffle to eliminate
the excess clearance.
