Bushman DC-X Series Fridges Freezer 130L Owner’s Manual

Bushman DC-X Series Fridges Freezer 130L

Congratulations on your purchase of a Bushman DC-X fridge. Please read these instructions carefully before installation and use.
Please be safe and use common sense and caution when installing, operating and cleaning this appliance. If you are unsure about any of these instructions, contact your local stockist before proceeding.

IMPORTANT INFORMATION

Do not lay your fridge on its back, top or sides or at any angle exceeding 30º. If your fridge has been incorrectly handled, ensure that the fridge is placed in a level upright position for 12 hours to allow the internal fluids to redistribute evenly.
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. To avoid injury and causing damage to the appliance, be extremely cautious when using sharp or pointed tools to complete this task.
Do not connect an appliance that has been damaged, contact your local dealer immediately.

INSTALLATION

Installation of the DC-X range of fridges must be completed by a suitably 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 a pure sine wave. Any fluctuations in generator current may damage the compressor.

WIRING

Wire your fridge on a dedicated circuit, directly to your battery bank. For optimum results, do not go via a buss bar, shared circuit or battery management system. You will need the correct sized wire depending on the distance from your power supply to the fridge. Please also ensure the earth is wired directly to your battery, not to a chassis. If your wiring is insufficient, your fridge may not perform correctly or may be even be damaged.

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.
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.

INSTALLATION INTO A CAVITY

DC-X fridges are designed to be installed in a cavity. A gap of minimum 50mm is recommended for the rear. Refer to the following table for the recommended cut-out dimensions. If you are using the mounting kit, allow an extra 5mm width for the mounting kit frame and screws.

MOUNTING KIT
The mounting kit is first affixed 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.

VENTILATION

Ventilation will have a significant 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 400cm2 each. Note that a 400mm x 200mm vent will have only a free cross section of approximately 400 cm2 (not 800 cm2).

IMPORTANT STEPS FOR EFFECTIVE OPERATION

THERMOSTAT
The thermostat should be set on the lowest number to keep your fridge cold. Do not use setting 7 as this causes very quick ice build-up. Start the fridge at setting 3 and see how it goes after 24 hours. 7 is the coldest setting and 1 is the warmest.

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, 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 critically important on the top shelf so the cold air from the freezer 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 5mm.
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 freezer compartment. Re-start the fridge on setting 4 and monitor after 24 hours.

CLEANING
Always keep the inside of the fridge clean and dry. Wash the inside of your fridge with luke warm water and a mild soap. Never use abrasive or corrosive cleaning agents, steel wool or scouring sponges. A soft sponge, towel, or soft brush is recommended.

STORAGE
Keep the door of the fridge ajar when the fridge is not in use, to allow fresh air to circulate inside the fridge compartment.

REMOVING THE FRIDGE DOOR – MOVING THE HINGES TO THE OPPOSITE SIDE

REMOVE THE DOOR

To remove the fridge door, position the fridge on a bench with the front edge overhanging so you can access the
bottom hinge screws.

1. Take the top hinge off first
2. Gently lift off the main door
3. Unscrew the bottom hinge. There is a small washer on the bottom hinge, make sure this doesn’t stick to the bottom of the fridge door!
4. Reposition the bottom hinge and screw into place
5. Sit the main door onto the bottom hinge (and washer)
6. Affix the top hinge screws finger tight only.
7. Align the door so it is square to the cabinet and closes freely without rubbing.
8. Tighten the top hinge screws fully.

MOVING THE DOOR HANDLE

1. Remove the 2 screws which hold the door handle in place. Access is provided under the logo sticker. You can more easily remove the sticker by applying moderate heat from a hair dryer.
2. Gently lift the door handle off.
3. Reposition the door handle on the preferred side.
4. Drill 2 small (2mm) pilot holes through the door handle for the original screws.
5. Reaffix the door handle using the original screws.
6. Reapply the logo sticker onto the door handle by applying moderate heat to the sticker.
7. Use the supplied DC-X Series sticker to cover the old screw holes.

REPLACING THE FRONT DOOR PANEL

1. Follow steps 1 to 2 under “Moving the door handle” above.
2. Gently remove the bottom door profile which supports the door panel. Using a screwdriver gently lever the bottom door profile outwards only. Do not lever it down.
3. Gently slide the original door panel down and out of the door.
4. Slide the new door panel upwards and into place.
5. Reposition the bottom door profile to be flush.
6. Continue from steps 3 to 8 under “Moving the door handle” above.

ADJUSTING THE DOOR LATCH

Whenever the door or hinges have been moved, please adjust the top metal rail that the door latch clips under. Loosen the screws and move the top metal rail towards the rear of the fridge cabinet until the plastic door latch just makes light contact. If there is more than 1mm of movement, this will need adjusting.
See diagram below:

RUBBER DOOR SEALS

1. It is important that the rubber door seals are making contact 100% of the way around the fridge cabinet.
2. There are magnets inside the rubber seal which pull towards the metal fridge cabinet to keep it airtight.
3. After you have adjusted your door latch, check to see that the rubber seal is making contact with the fridge cabinet on all 4 sides. If there is even a small gap, this will affect the performance of your fridge.
4. Starting from a corner, gently heat up the rubber seal with a hair dryer or light heat from a heat gun (be careful not to overheat the rubber or it will melt). As the rubber heats up, the magnets inside will pull the seal towards the fridge cabinet. Slowly work your way along the rubber from one corner to the other until it is fully sealed.

TROUBLESHOOTING GUIDE

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

1. 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 following minimum voltage for the compressor to start (Cut-in) or stop (Cut-out). VOLTAGE| CUT OUT| CUT IN
   ---|---|---
   12 V| 9.6 V| 10.9 V
   24 V| 21.3 V| 22.7 V

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  **  

**

2. VENTILATION AND AIR-FLOW

   • There is adequate ventilation and free air flow to the compressor area – see page 3 + 8
   • The fridge is not installed in a sealed cavity, container or canopy
   • The condensor fan is operating

3. ICE BUILD UP
   Ice will slowly build up on the freezer section 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 (6 or 7) 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:

   • Check the rubber door seal is touching the fridge cabinet all the way around on all 4 sides – see page 5
   • Check the door closes freely without rubbing on anything – see page 4
   • Check the door latch has a tight fit when closed – see page 5
   • Defrost the fridge, dry it out and start again on thermostat setting 4 or 5 see page 4

4. OPERATING THE FRIDGE

   • Space items in the fridge, this is critically important on the top shelf – see page 3
   • Set the thermostat to the lowest number possible – 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

From mid 2021 onwards all Bushman DC-X series are fitted with a red LED error light.

• Mid 2021 – mid 2022 the red LED is located on the compressor module.
• Mid 2022 onwards the red LED is located inside the interior light housing.

The number of flashes corresponds to the following error type.

The voltage is outside the cut-out setting.

2| TOO MAY START ATTTEMPTS (OR FAN OVER CURRENT)

This generally indicates the compressor has had too many start attempts due to battery

protection cut-out. It could also indicate fan overload of more than 0.5A but this is extremely rare.

3| MOTOR START ERROR

The rotor is blocked or the differential pressure in the refrigeration system is too high (>5 bar)

4| MINIMUM MOTOR SPEED ERROR

Refrigeration system is overloaded, and motor cannot maintain minimum speed (1850 rpm)

5| THERMAL CUT-OUT

Refrigeration system overloaded or ambient temperature is too high.
