For installations where the depth of the enclosure is
greater than 26 inches, additional baffling may be
required to direct the airflow thru the absorber and
condenser section of the refrigerator as shown in Fig 10.
The refrigerator must be positioned with respect to the
upper roof vent so that a minimum ventilation height is
achieved as illustrated in Fig 11. The minimum
ventilation heights are:
Refrigerator Min Ventilation Height
HE-06xx 57.75 in
HE-08xx 63.75 in
Slide-Out
Applications
There are some vehicle applications, such as in slide-out
configurations, where a roof vent is not practical. For those
applications, the roof vent is replaced with an upper side
vent as shown in Fig 14 and Fig 15 below. It is important
to note that for these installations with restricted air flow,
Atwood offers refrigerator models with a built-in external
fan to insure that adequate ventilation is provided and to
insure optimal cooling performance.
For installations with an enclosure depth of between 24”
and 26”, the installation is given in Fig 14. It is important to
install the two baffle sections highlighted in red in the
diagram. These baffles can be pieces of sheet metal
which extend the entire width of the refrigerator cabinet.
The main objective of these baffles is to force the
ventilation air through the condenser fin section and to
prevent hot air from collecting above the condenser and
directing it out the upper side vent.
For installations with an enclosure depth greater than 26”,
the installation is given in Fig 15. Both baffle sections must
be the entire width of the refrigerator cabinet. The lower
box baffle (highlighted in red) forces the air from the lower
side vent up through the absorber coils. It is very important
that the top section of the lower box baffle extend up to
within an inch of the lower corner of the condenser fin to
insure that air is directed thru condenser section as well.
The top baffle section can be made of sheet metal and
must also extend the entire width of the cabinet. It’s
purpose is to prevent hot air from collecting above the
condenser and directing it out the upper side vent.
Minimum height from bottom of the enclosure to the top of
upper side vent is:
HE-06xx is 55 inch
HE-08xx is 62 inch
