1.1 GENERAL INFORMATIONIndel B refrigerators guarantee performance and reliability. Provided with a totally hermetic compressor, they offer 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 efficiently 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 proper 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 condensate water 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.

ENGLISHThe refrigerators are pre-set for being assembled 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 SYSTEMTo have the refrigerator operate with the vehicle battery, please refer to the instruction manual of the vehicle’s manufacturer. WIRING SYSTEM: FUNCTIONS AND FEATURES (WITH AUXILIARY BATTERY)The electronic unit of the compressor is a piece of electronic equipment which pilots the motor of the compressor and carries out all the controls and electrical protection of the system. Its main features are the following:• Protection of the battery with automatic turning off of the compressor when the feeding voltage reaches
the minimum threshold (cut out)• The compressor will start up automatically again when the voltage goes back to normal values (cut in).
TABLE FOR BATTERY SAVER TRIPPING VOLTAGES
1.3 WIRING CONNECTIONSWhen you connect the refrigerator, you must remember the following:1) Use cables having the proper cross section (see table) to make the feeding lines. If possible, such cables
should be without any joints on the leads which could lead to voltage drops.2) If the wiring system of the vehicle is insufficient or not properly sized for the refrigerator, connect it directly
to the battery without using intermediate wiring.3) Any switches must have a breaking load not less than 20 A4) Make sure the polarity is right: connect the red cable to the positive terminal (+) and the black cable to
the negative terminal (-).5) Protect the feeding line with a 15 A fuse.

Warning Never connect bare electric wires, and use only connectors of a size suitable to the cross section of the cable being used.

1.4 SETTING THE INSIDE TEMPERATUREThe 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, under the lamp.
1.4.1 DEFROSTINGDefrosting must be carried out when the ice layer is thicker than 4 mm.Set the thermostat at the OFF position. While defrosting, keep food and beverages in a cool place. Do not use any sharp metal object to remove the ice or frost. Do not start the refrigerator up again until it is completely defrosted and dry. Also empty the main tray.
1.5 MAINTENANCE
WarningBefore every maintenance operation, disconnect the power supply from the electric outlet. In case of refrigerator wrong operation, contact the Indel B Service Center.
1.5.1 CLEANINGPeriodically 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 its inside to prevent mould and bad smells formation.
WarningDo NOT wash the refrigerator drawers and parts in a Dishwasher.
1.6 USEFUL ADVICESIf 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 circuits are connected 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.
1st - DTNA Service Bulletins, pertaining to Indel B refrigerators, should be reviewed prior to replacing any components.
2nd - If nothing is running or only fan is running, using a volt meter on 20v DC setting, check voltage at fridge with truck off and fridge off . 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 fix them”).
3rd - If the PCB load dump circuit board has a poor connection on the ECU,place a zip tie around the ECU/circuit board and verify operation.
4th - 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.
5th - If fan runs and compressor does not, change ECU and check if compressor is now running.
