USHMAN DC230-X DIGITAL

230L 12V / 24V DC Upright Fridge

Congratulations on your purchase of a Bushman DC230-X. Please read these instructions carefully before installation and use.

IMPORTANT INFORMATION

Do not lay your fridge on its back, top or sides or at any angle exceeding 30º. If your fridge has been handled this way, stand the fridge upright for 12 hrs to allow the internal fluids to redistribute evenly before use. Never operate your fridge directly from a 240 V or AC power supply. Do not use a modified sine wave inverter to operate your fridge.

PRIOR TO INSTALLATION

DELIVERY
At delivery, please check that the fridge is complete and is not damaged in any way. Remove all packaging and securing tapes from the fridge. Do not connect an appliance that has been damaged, contact Bushman immediately

INSTALLATION
Installation of the DC230-X must be completed by a trained professional only

POWER SUPPLY
Your fridge must be connected to a stable and regulated 12 V or 24 V DC power supply only. The compressor
will automatically detect which voltage is present and adjust accordingly.

If you are using a generator or other power supply, the output must be only a pure sine wave.

WIRING
Always wire your fridge directly to your battery terminals. Do not run the wires via a buss bar, battery management system or shared circuit. Please also ensure the earth is wired directly to your battery, not to a chassis.

Ensure the wiring polarity is correct. Connect the red wire to the positive terminal (+) and the black wire to the negative terminal (-). Never connect bare electric wires. Use only connections of a size suitable for the cross section of the wire being used.

CROSS SECTION IN MM 2| AWG (AMERICAN WIRE GAUGE)| MAXIMUM LENGTH OF WIRE IN METRES
---|---|---
12 V| 24 V
2.5| 14| 2.5| 5
4| 12| 4| 8
6| 10| 6| 12
10| 8| 10| 20

ISOLATION SWITCH AND FUSE
We recommend installing an isolation switch for the fridge circuit as close to your battery bank as possible. Any
switches must have a breaking load not less than 20 A on 12 V or 10 A on 24 V.

The power supply wiring must also be protected with a 15 A fuse.

INSTALLATION IN A CAVITY
Your new fridge is designed to be installed in a cavity. We recommend allowing a minimum 5mm gap on each side and the top for ease of installation. A minimum gap of 35mm is required for the rear. Refer to the following table for the recommended cut-out dimensions.

MOUNTING KIT
Position the mounting kit flush with the front edge of the fridge cabinet and mark the position of the holes. Drill
shallow, 3mm drill bit, pilot holes through the sheet metal cabinet. Affix the mounting kit to the side and top of
the fridge cabinet using the screws provided.
Once the fridge has been connected to the power supply and moved into its final position, the mounting kit can
be affixed to the front of the cavity.

INTERNAL MOUNTING SLEEVES
There are 4 internal mounting sleeves on the inside of the fridge cabinet, and 2 internal mounting sleeves in the inside of the freezer compartment. Access is provided by gently levering off the plastic caps. M5 screws or bolts need to be used. Drill 4mm pilot holes through the plastic sleeve and right through the fridge cabinet sides. Put a small nylon washer onto the screw / bolt heads before inserting. Ensure that the exterior of the fridge cabinet is flush with your cabinetwork before affixing the screws / bolts. If there is a gap, pack it out with a suitable hard material. Check for screw / bolt tightness after your first trip.

BOLTING THROUGH THE REAR CHASSIS
You can bolt through the rear metal chassis (where the compressor sits). We recommend using M8 or M10 bolts for this application. Adding bolts here provides extra strength for you installation to compliment the mounting kit or internal mounting sleeves.

VENTILATION
Ventilation will have a critical impact on the efficient operation of your fridge. A minimum of 2 vents needs to be provided from the rear of the fridge cavity to the outside environment, or to the main room where the fridge is located. The vents should be located at the bottom and top of the fridge cavity and have a free cross section of minimum 600cm2 each. Note that a 500mm x 250mm vent will have only a free cross section of approximately 600 cm2 (not 1250 cm2).

OPERATING THE FRIDGE

ON / OFF Toggles the fridge between “standby” and “power on” modes.

• Standby In Standby mode, the screen is blank.
• Power on In Power on mode, the screen displays the fridge temperature

PLUS / MINUS Increase or decrease the fridge set temperature (0˚C to 10˚C)

ADVANCED SETTINGS
To enter the advanced settings mode, put the fridge into standby mode, then press and hold both the PLUS and MINUS buttons for 3 seconds. Use the ON / OFF button to toggle between Battery Protection settings and Celsius / Farenheit settings:

Battery Protection / Low Voltage
We strongly recommend using the default battery protection settings because all 12V / 24V circuits will have voltage drop between your battery and the fridge compressor. If you change these settings, your fridge may turn off and on intermittently and without your knowledge and perform poorly. Use the PLUS and MINUS button to switch between Low, Medium and High as follows:

| 12 V| 24 V
---|---|---
Cut out| Cut in| Cut out| Cut in
| High| 11.1| 12.4| 24.3| 25.7
| Medium| 10.4| 11.7| 22.8| 24.2
| Low (Default)| 9.6| 10.9| 21.3| 22.7

Celsius C˚or Farenheit F˚

Default setting is Celsius. To change your temperature setting from Celsius to Farenhenheit, use the PLUS and
MINUS buttons.

EQUALISING THE FRIDGE
During the first 24 hours of operation, your compressor will operate for longer than usual. This process allows
the internal air temperature, food, drinks, condenser, compressor, and insulation to equalise.

KEEP HOT / WET ITEMS OUT OF THE FRIDGE
Try and keep hot or wet items out of the fridge as they are a prime source of moisture and ice build-up.

SPACE ITEMS, ESPECIALLY ON THE TOP SHELF
It’s important to keep some space between your items in the fridge so that the cold air can circulate. This is ritically important on the top shelf so the cold air from the cooling element can fall into the fridge cabinet. Round items like cans and jars are good for the top shelf as they allow space around them. Packets of meat etc are probably the worst items as they create an insulated barrier between the top shelf and the rest of the fridge.

RUBBER SEALS ARE CLEAN
Keep your rubber seals clean and free from stickiness. You can clean the rubber seals and the front edge of the fridge cabinet with warm, soapy water.

HAVE GOODS INSIDE THE FRIDGE
The fridge will not operate properly if it is empty, as air does not hold temperature well. If you are using a wireless thermometer the temperature readout will fluctuate significantly with the changes in air temperature, whilst your drinks inside the fridge will not vary much at all.

DEFROSTING
Defrosting needs to be carried out when the ice layer reaches a thickness of 5 – 10mm. Turn off the power to the fridge and move your food and beverages to another cool place. Do not use any objects to remove the ice or frost, it must be allowed to melt naturally. Once the ice has melted, thoroughly dry the inside of the fridge and fre partment. Re-start the fridge on setting 4 and monitor after 24 hours.

CLEANING
Wash the inside of your fridge with a soft cloth, lukewarm water, and a mild soap. Never use abrasive or corrosive cleaning agents, steel wool, scouring sponges or scrapers of any kind.

STORAGE
When the fridge is not in use, please disconnect power to the fridge completely. Keep the doors of the fridge ajar when the fridge is not in use, to allow fresh air to circulate inside the fridge.

MOVING THE DOOR HINGES FROM ONE SIDE TO THE OTHER
Please follow these instructions carefully. It is imperative that the doors are aligned correctly when the hinges are moved from one side to the other. Incorrectly aligned the doors will cause significant ice build-up and failure of the door latch while underway. In our experience this is a 2-person job. If you are unsure at any stage, please call Bushman head office on (03) 8080 9990 for assistance.

SWAPPING THE DOOR HINGES AND CORRECTLY ALIGNING THE DOOR HANDLE & CATCH

1. Tilt the fridge backwards 45˚ and lean it gently against a wall for support.
2. Carefully remove the top, middle and bottom hinges and both doors. Ensure all hinge pin washers are kept in place. You will need to remove the freezer door catch and fridge door catch at the same time.
3. Move the bottom hinge to the preferred side of fridge cabinet. Only tighten screws finger tight.
4. Move the bottom hinge pin to the other side of the hinge.
5. Locate main door onto the bottom hinge. Ensure any washers are still in place.
6. Affix middle hinge to fridge cabinet. Only tighten screws finger tight.
7. Follow step 1 to 7 in MOVING THE DOOR HANDLE below to reposition the fridge door handle.
8. Position the main door so it is square with the fridge cabinet.
9. The door handle must be snug under the door catch. See diagram below. If not, manipulate the position of the door and both door hinges until the door handle is making light contact directly under the catch. Tighten bottom and middle hinge screws fully in this position.
10. Check the fridge door opens and closes freely without rubbing and clips snug under the door catch.
11. Locate freezer door onto the middle hinge. Ensure any washers are still in place.
12. Affix top hinge to fridge cabinet. Only tighten screws finger tight.
13. Follow step 1 to 7 in MOVING THE DOOR HANDLE below to reposition the freezer door handle.
14. Align the freezer door until it is square with the fridge cabinet. Tighten top hinge screws fully.

TROUBLESHOOTING GUIDE

Please check each of these 4 points. All 4 need to be right for your fridge to operate correctly.

VOLTAGE
The most common cause of an incorrectly functioning fridge, or a fridge that starts and stops and doesn’t get cold, is a lack of consistent voltage. Danfoss compressors have built in battery protection and need the followin minimum default voltage for the compressor to start (Cut-in) or continue running (Cut-out). If you have changed these settings, we strongly recommend only using the default Low setting – see page 3

Note that when the compressor starts it will draw approximately 8A for 1⁄2 second to turn the compressor over.
When this 8A load is applied, the voltage can drop by 2V – 3V, causing the compressor to turn off again  This often happens at night when the battery gets a bit lower (no solar input) or when the car alternator hasn’t been started for a while (no alternator input) or if there is a weak spot somewhere in the electrical system (weak join, weak solder, undersized wire, worn battery).

To isolate this problem, use a different, direct power supply
Connect the red and black power wires from the compressor directly to a different 12V power source (for example
a fully charged deep cycle 12V battery). It is important to run these two wires directly to the power source, without
any unnecessary connections, plugs, solar, battery management, power distribution or buss bars. If the fridge now
runs correctly, there is a power supply issue somewhere.

Get an electrician to check

• The polarity of the connections are correct
• The wiring between the fridge and battery is correctly sized – see page 2
• Any connections or joins in the wire between the fridge and the power source are 100%
• The battery is not wearing out and is capable of consistently providing 12 volts when a 10 amp load is placed on it
• The voltage to the compressor is still 12V when a 10 A load is placed on the wires

VENTILATION AND AIR-FLOW

• There is adequate ventilation and free air flow to the compressor area – see pages 2 + 6
• The fridge is not installed in a sealed cavity, container or canopy
• The condensor fan is operating

ICE BUILD UP
Ice will slowly build up on the back of the fridge wall over many weeks. This is a normal part of the operation of a
low-power cooling system. Excessive ice build-up is a problem as the ice eventually insulates the cooling element
and hinders the fridge’s ability to cool. In this instance, turning the thermostat up to flat out (0˚ C) will cause ice to
build up even faster. Therefore, slowing the ice build-up from the start is the key. Please follow these 4 steps:

• a) Check the rubber door seal is touching the fridge cabinet all the way around on all 4 sides – see page 4
• b) Check the door closes freely without rubbing on anything – see page 4
• c) Check the fridge door handle has a snug fit directly under the door catch when closed – see page 4
• d) Defrost the fridge, dry it out and start again on thermostat setting 3˚C, monitor after 24hrs – see page 3

OPERATING THE FRIDG

• Space items in the fridge, this is critically important on the top shelf – see page 3
• Only open the fridge or freezer door for short periods of time and when necessary
• Do not place hot or wet items inside the fridge

RED LED ERROR LIGHT

A red LED light is installed inside the fridge light. The number of flashes corresponds to the following error type.

indicates the compressor has had too many start attempts due to low voltage cut-out. It could also indicate fan overload of more than 0.5A but this is extremely rare.
3| MOTOR START ERRORThe rotor is blocked or the pressure in the refrigeration system is too high (>5 bar)
4| MINIMUM MOTOR SPEED ERRORRefrigeration system is overloaded, and motor cannot maintain minimum speed (1850 rpm)
5| THERMAL CUT-OUTRefrigeration system overloaded or ambient temperature is too high.

THERMOSTAT FAILURE
If the NTC thermistor has a short circuit or no connection, E6 will display on the screen.
