This appliance has been designed for refrigeration or freezing purposes and can
be operated on both AC and DC power supplies. The internal power supply will
automatically switch from DC to AC power, and back.

The model and serial number may be found on the compressor cover on the side of
the unit.

Before using your unit, record and retain the model and serial number for future
reference and warranty purposes. It is also suggested that you retain the date and
proof of purchase for warranty purposes.

GENERAL

Your ENGEL portable refrigerator should be placed on a level and solid surface.
The compressor is shock mounted for in-transit operation.

Be sure your refrigerator is not in direct sunlight, near a gas stove, heater or
any other heat-generating appliances. Provide adequate ventilation for your
refrigerator by keeping it at least 6 inches away from solid walls. This will result in
maximum cooling e󱐰ciency and minimum electric current consumption while limiting
condensation. Avoid placing it in an area where it may be accidentally splashed or
sprayed with water or other substance that might enter the electrical compartment.

Your refrigerator has been thoroughly cleaned before shipment from the factory.
It is advisable, however, to clean the interior once more before use. Clean the
interior with a cloth moistened in warm water and wipe with a dry cloth. After
cleaning, replace interior components.

CAUTION

1. Do not expose your ENGEL to saltwater which is corrosive and may cause
electrical shock.

2. Never store gasoline or other flammable vapors and liquids in or near your
refrigerator as these could cause an explosion.

3. Do not touch the evaporator or other metal parts inside the cabinet with a wet
hand. This may cause frostbite.

4. Do not remove or modify any of the product's electrical components.

INSTALLING HANDLES

Lifting handles are furnished with larger models (MT45F-U1CD-P) and are packed
loose inside the refrigerator. They are to be installed using the screws and tapped
holes provided.

CONNECTING TO THE POWER SOURCE

120 VOLT AC OPERATION IN YOUR HOME

Your refrigerator needs so little power that it may be connected to any AC 120V
receptacle in your home. To do this, set the thermostat control knob to "OFF" and
insert the square plug of the AC cord in the connector on the refrigerator and the
standard plug in a wall socket in your home. The power consumption is less than a
standard light bulb.

12/24 VOLT DC OPERATION IN YOUR CAR, TRUCK, SUV, BOAT, TRAILER,
RV, ETC.

Battery voltage varies with the type of car / truck / SUV / boat / RV you own. Most
cars, trucks and boats use a 12 Volt system. Your refrigerator needs either a 12 Volt
or a 24 Volt battery with a negative ground.

For Japanese

Cover

American＋Australian built vehicles

Set the thermostat control knob to "OFF" and insert one end of the DC Cord / Plug
(provided with the refrigerator) into the connector and the other end into the power
port of your car. In most passenger cars, the power port is on the dashboard.

NOTE: When not using the refrigerator, remove the plug from the power port to
prevent discharge of your car battery.

Most SUVs and minivans have a dedicated power port in the rear of the vehicle to
make connecting the refrigerator easier.

IMPORTANT:

WIRING
Never use wiring less than AWG #12 between the battery and refrigerator.

HARDWIRING
When hardwiring your refrigerator to a battery, make sure there is a 10 Amp fuse for
MT45F-U1CD-P inline on the positive wire.

BE SURE THE POWER SUPPLY POLARITY IS CORRECT
In the event that the green refrigerator light fails to glow, inspect the power source
for proper voltage and correct polarity. The inner contact point of the DC Cord /
Plug must be positive and the outer contact negative (ground).

REDUCE RADIO NOISE INTERFERENCE – CONNECT REFRIGERATOR DIRECTLY
TO THE BATTERY
Reducing radio noise interference can be accomplished by twisting the power supply
wires together, attaching them directly to the battery and adding a 10 Amp fuse for
MT45F-U1CD-P near the positive battery connection. Avoid splicing other devices
into this circuit as interference may occur.

BATTERY CHARGERS
Never hook the refrigerator directly to a battery charger. It must only be attached to
a battery.

OPERATING YOUR REFRIGERATOR USING A PORTABLE GENERATOR
The internal refrigerator power supply unit may be damaged if powered by older style
generators without automatic voltage regulation. The only acceptable generators to
use are those that are “inverter style” or those with over-voltage protection. Please
contact your ENGEL Dealer for additional instruction on safe use when powering
your refrigerator with a portable generator.

CAUTION : The use of an extension cord is not recommended.

BATTERY PROTECTION

This fridge is equipped with a battery monitor cutting the compressor in or out in
order to protect the battery. When the “MODE” button is pressed twice, the LED
display will be blinking the current battery monitor state “OFF” or “LO” or “HI”

default OFF）.

（

The “SELECT” button during this mode will display the OFF→LO→HI change.
After pre-setting the battery monitor, the LED display will stop blinking （after a
few second）, indicating the temperature has been set （locked）. The value by each
setting is shown on the below table. The battery monitor is not a necessary feature
for the fridge to operate. It may be left in the off position at all time.

BATTERY MAINTENANCE

DC CORD

MAINTENANCE OF THE BATTERY IS IMPORTANT
If your battery is old (more than 3 years) or not properly charged, a decline in the
cooling performance of your refrigerator can be expected.

NEVER USE A BATTERY CHARGER, AC/DC CONVERTER, OR RECTIFIER ETC. IN
LIEU OF A BATTERY
These electrical supplies generate high ripples, or surge voltages, which could result
in damaging your ENGEL's internal power supply.

NEVER USE A COMMERCIAL INVERTER OR CONVERTER
Never use a commercial inverter or converter for operating your refrigerator on AC.
These devices do not hold the required constant frequency. It is safer and more
energy e󱐰cient to run your refrigerator directly with DC power.

OPERATION

To start your refrigerator, set the thermostat control dial to "ON." Your refrigerator
should start operating. The interior should start getting cool to touch within a few
minutes.

PROTECTION SYSTEM

The DC power cord is made for a negative (-) ground system. Your refrigerator has
a high current protection system incorporated into the electronic circuit to prevent
damage to the power supply which may occur due to a reverse connection.

If your refrigerator does not operate and the power lamp on the refrigerator is not
illuminated, you may have:

- Connected the refrigerator with the incorrect polarity

- Blown a fuse in the DC Cord / Plug

- Blown a blade fuse on the refrigerator

- Insu󱐰cient voltage from the power source

- A problem in the inverter

STORING FOOD IN THE REFRIGERATOR

The following simple instructions on storage of food in the refrigerator will enable
you to get the best results when using your ENGEL refrigerator / freezer.

REFRIGERATED FOOD
To prevent drying out and the transfer of odors from one food to another, foods
should always be stored in covered dishes, sealed plastic bags or wrapped in foil.

FROZEN FOOD
An ordinary packet of frozen food can be stored in the freezer for several days with
the thermostat set to "5."

If frozen food is allowed to thaw, under no circumstances should you attempt to
refreeze it.

DEFROSTING YOUR REFRIGERATOR / FREEZER

Set the thermostat control knob to "OFF." When the frost has melted, wipe down the
interior of your refrigerator with a soft, dry cloth. Never use a sharp object to chip
or scratch at the frost. This may result in puncturing the side evaporator walls which
will cause the refrigerant gas to escape.

CLEANING AND MAINTENANCE OF YOUR REFRIGERATOR / FREEZER

BOX, DOOR & WIRE BASKET
To clean the box, door and basket, wipe clean with a soft, dry cloth. To remove dirt,
use a cloth moistened by a warm, mild detergent solution. Never use hot water or
harsh chemicals. After cleaning, wipe with a dry cloth.

LID GASKET
Wipe away dirt with a soft cloth moistened by a mild detergent. Do not soak the cloth
excessively. If water gets inside the side walls of your refrigerator, the insulating
e󱐯ect may become temporarily impaired.

CAUTION
Never use a brush, powder soap, cleanser, acid, benzene, gasoline or mineral
thinners. These tend to leave scratches on the plastic coating.
