Installation Manual 5
- 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 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
[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).
- 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 63 inches (see Art01588 and Art01589).
- Align the upper exhaust vent horizontally above the
lower intake vent [9].
- 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 1/4 inch or less of clear-
ance between the baffle and the top of the
refrigerator and that the baffle overlaps the
refrigerator 1 inch or less [19].
- 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 [124].
- 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.
- When using an upper side-wall exhaust vent:
- If the depth of the enclosure is more than 24 inches
and less than 26 inches [27], install a bent aluminum
or galvanized steel sheet baffle [26] to the rear of the
enclosure (See Art01588).
- Make sure that the bend of the baffle is the full
width of the inside of the enclosure.
- Make sure that the bend of the baffle is flush with
the bottom edge of the upper intake vent door
frame.
- Make sure that the top edge of the baffle is 1/4
inch or less [124] below the condenser [11] and
that there is 1/4 inch or less clearance [124]
between the lower rear corner of the condenser
and the baffle.
- If the depth of the enclosure is more than 26 inches
[27], install a wood or an aluminum or galvanized steel
sheet solid box baffle [21] between the lower intake
vent and the upper exhaust vent (See Art01589).
- Make sure that the solid box baffle is the full width
of the inside of the enclosure.
- Make sure that the bottom of the solid box baffle is
18 inches to 18 1/2 inches above the bottom of the
enclosure [17] (4 1/4 inches to 4 3/4 inches above
the top of the lower intake vent opening REF) [18] .
- Make sure that the back of the solid box baffle is
perpendicular to the bottom of the enclosure.
- Make sure that the horizontal top of the solid box
baffle is even with the bottom edge of the upper
exhaust vent [24].
- Make sure that the vertical top edge of the baffle is
1/4 inch or less [24] below the lower rear corner of
the condenser [11].
- Make sure that there is 1/4 inch or less clearance
[124] between the rear of the condenser and the
baffle.
