Ventilation
Overview
The refrigerator is made for a built-in installation. Correct ventilation
is necessary for the correct operation of the refrigerator and to
increase the life of the refrigerator cooling system.
Ventilation allows the natural fl ow of air that is necessary for good
ventilation. Cooler air comes in through the lower vent, goes
around the refrigerator coils where it removes the excess heat
from the refrigerator components , and goes out through the upper
vent / control cover. If this air fl ow is blocked or decreased, the
refrigerator will not cool correctly. Do not install the refrigerator in a
completely enclosed area such as a closet or a cabinet.
The refrigerator has built-in vents at
the top and the bottom. Make sure that
the air fl ow through these vents is not
blocked in any way. Blockage of the air
fl ow through these vents can:
■ Shorten the life of the refrigerator cool-
ing system.
■ Cause poor cooling performance of the
refrigerator.
■ Cause continuous operation of the
refrigerator cooling system.
■ Cause fast battery discharge.
■ Void the refrigerator warranty.

WARNING
Installation
To confi rm that installation is adequate, make sure:
■ Ventilation is adequate. Refer to "Ventilation" section.
■ Electrical components are installed and operating in a safe
condition.
■ Refrigerator is installed on a solid and level fl oor (not on carpet)
and secured.
■ The fl oor is able to support the weight of the refrigerator and all
of its contents.
12 Volts DC Electrical Connection
To reduce the risk of electrical interference from other DC
appliances and induction from voltage spikes:
■ The refrigerator must have an independent 12 volt supply and
not be on the same circuit as other DC appliances.
■ Route the DC power supply wires, including the fuses, directly
from the battery to the refrigerator.
The use of a battery in parallel and
between the refrigerator and any
electrically fi ltered DC power converter or
battery charger used to supply DC power
to the refrigerator is recommended.
■ Power converters or battery chargers used to supply DC power
are examples of installations that should have parallel battery
operation.
■ If an electrically fi ltered DC power converter is used as the sole
source of power, it must have a maximum DC ripple voltage of
less than or equal to 250mV.
Polarity
If the DC leads are installed incorrectly,
the refrigerator will not operate.
■ Connect the DC (positive) supply wire from the battery to the
red wire of the refrigerator.
■ Connect the DC (negative) supply wire from the battery to the
black wire of the refrigerator.
