The optimum installation is illustrated in Fi
g
ure 1.
1. Area above refri
g
erator blocked
(
baffled
)
off to
prevent trappin
g
of hot air above the refri
g
erator.
2. 0 -1/4 inch clearance at the top of the refri
g
erator.
3. Exhaust vent centered directl
y
over refri
g
era-
tor’s condenser.
4. 0 - 1 inch at rear of the refri
g
erator.
5. 0 inch clearance at bottom of refri
g
erator.

1. Exhaust vent openin
g
is inboard in relation to
the rear of the refri
g
erator.
2. Baffles added to the top of the refri
g
erator to
assist in directin
g
air flow out the exhaust vent.
3. 0-1/4 inch clearance at the top of the refri

erator.
4. An
g
le between baffles and rear top ed
g
e of the

erator not to exceed 45 de
g
rees.
5. Deflectors added at rear in strate
g
ic locations
ad
j
acent to the coolin
g
units condenser and ab-
