CHAPTER 1
INSTRUCTIONS FOR USE

1 USER MANUAL
Warning: carefully read these instructions and the safety notices before using the
refrigerator.
1.1 GENERAL INFORMATION
Indel B refrigerators guarantee performance and reliability.
Provided with a totally hermetic compressor, they oer a minimal power consumption and noise level. All
the models are extremely easy to install. They can work even if they are assembled at a slant of up to 30°.
In order to make sure that your Indel B refrigerator works as eciently as possible, please pay attention to
the following general instructions:
• Opening the door of the refrigerator uselessly increases the waste of energy;
• Proper ventilation of the compressor and of the condenser unit reduces the energy consumption and
also ensures the yield;
• The wiring system of the vehicle is in good condition. Routinely check the batteries and the charge
level. Follow the instructions about the cable cross sections and the fuse connections strictly;
• Keep the inside of the refrigerator clean and dry. Remove any water condensation which might gather
in the tray under the freezer compartment;
• Keep the door of the refrigerator slightly open in order to air it out if you do not use it for a long time,
for example in winter.
The refrigerators are pre-set for being assembly in a niche of the truck.
It is very important for the refrigerating unit, consisting of the compressor and the condenser, to be well
ventilated, with the cool air coming in from the bottom and going out from the top.
You must ensure proper ventilation of the refrigerating unit.

1.2 WIRING SYSTEM
To operate the refrigerator on the vehicle battery, please refer to the instruction manual of the vehicle's
manufacturer.
WIRING SYSTEM: FUNCTIONS AND FEATURES WITH AUXILIARY
BATTERY
The electronic control unit of the compressor is an electronic equipment which controls the motor of the
compressor, takes care of the system and protects the electrical components.
Its main features are the following:
• Protection of the battery with a feature that automatically turns o the compressor when the supply
voltage reaches the minimum threshold (cut out).
• The compressor will start up automatically again when the voltage goes back to normal values (cut in).

WARNING
Never connect non insulated cables, and use only connectors of a size suitable to the cross
section of the cable being used.
1.3 SETTING THE INSIDE TEMPERATURE
The refrigerators are provided with a manual thermostat. Turn it clockwise to lower the temperature, and
turn it counterclockwise to raise the temperature and activate the ON-OFF switch in its end position. The
knob of the thermostat is located inside the refrigerator, on the right side, as shown in Fig. 6.

1.4 FILLING
Do not put hot food into the refrigerator.
Make sure the door is always well closed, and keep the door open to a minimum.
1.5 DEFROSTING
Since the evaporator operates at temperatures well below freezing, ice and frost will inevitably form upon
it.
The humidity in the air, the temperature and the number of times the door is opened will have a signicant
impact on frost formation.
The refrigerator should always be defrosted when the layer of frost on the evaporator reaches a thickness
of 3-4 mm or more.
Turn o the refrigerator by turning the thermostat to its 0 position.
Defrosting should be performed when the products can remain as cool as possible outside of the
refrigerator itself. Do not use sharp objects to remove ice and frost from the evaporator, as this could
damage it and result in leaks.
Only turn the refrigerator back on once it has been defrosted, cleaned and thoroughly dried. Remove,
empty and dry the drip tray beneath the evaporator. A towel can be placed at the base of the refrigerator
during the defrosting procedure in order to facilitate water collection.
1.6 CLEANING
Periodically clean the inside of the refrigerator using sodium carbonate dissolved in lukewarm water.
Avoid using abrasive products, cleaners or soaps. After cleaning, rinse with fresh water and dry with
care. When you are not using the refrigerator, clean and dry the inside to prevent mold and bad smells
formation.
WARNING
Do NOT wash the refrigerator drawers and parts in a dishwasher.

1.7 MAINTENANCE
WARNING
Before every maintenance operation, disconnect the power supply from the main connector.
1.8 USEFUL ADVICES
If the refrigerator does not work, or if it works incorrectly, before referring to our after sales service
(Customer Care Dept - Indel B North America - ph 502-867-2888), make sure that:
a) refrigerator has correct voltage input.
b) the connections are secured correctly.
c) the ventilation grids are not obstructed.
d) the refrigerating unit is not near a source of heat.
e) the refrigerator fuse is not blown.
f) freezer/evaporator has not been punctured or damaged. This type of damage is considered to be
non-warrantable.
• DTNA Service Bulletins, pertaining to Indel B refrigerators, should be reviewed prior to replacing any
components.
• If nothing is running or only fan is running, using a volt meter on 20v DC setting, check voltage at
fridge with truck o and fridge o . What is voltage? Turn fridge on and see if voltage drops below 11
volts. If yes, there is most likely a wiring issue with the truck. If no, proceed to next step (for details go to
Chapter 2 “How to detect functional problems and x them”).
• If fan does not run, bypass thermostat wires on ECU terminal C to T. If fan now runs, also check if
compressor is now running and if yes replace thermostat.
• If fan runs and compressor does not, change ECU and check if compressor is now running.
WARNING
The power cable must be replaced only by qualied technical personnel and, in any case, by a
service authorized by the manufacturer.
Indel B disclaims any responsibility if the above instructions and conditions are not followed or
not met.

2.2 ASSEMBLY
The refrigerator is suitable to be mounted into the specic furniture. It can be xed through the upper
ange and the lower ange:
- Insert the two hooks into the lower ange (Fig.1);
- Use three screws to fasten the upper ange to the matching furniture ange (Fig.2).
FIG. 1 FIG. 2
11 HOOK
It is very important for the refrigeration unit, consisting of the compressor and the condenser, to be well
ventilated, with the cool air coming in from the bottom and going out from the top. You must ensure
proper ventilation of the refrigerating unit (Fig.3, Fig.4).
FIG. 3 FIG. 4

15
2.3 WIRING CONNECTIONS
When you connect the refrigerator, you must follow the instruction below:
1) Connect the refrigerator power cable directly to the connector in the vehicle (Fig.5).
2) Any switches must have a breaking load not less than 20 A.
3) Make sure the polarity is right: connect the red cable to the positive terminal (+) and the black cable to
the negative terminal (-).
4) For system protection, the fuse must be installed in the positive wires (+) as close as possible to the
battery. We recommend using 15 A fuses for 12 V. If using a main switch, it must be able to withstand
a minimum current of 20 A. Avoid extra junctions in wiring to prevent voltage drops that can inuence
battery protection settings.
WARNING
The use of cables having an insucient cross section may lead to the compressor stopping even when
the battery is charged.
