6 Installing and connecting the device

6.1 Removing the cooling unit (MR07 only)

▶ Bend back the guard plate (fig. 3 1, page 2) slightly.
Remove the two fastening screws (fig. 3 3, page 2) using a long Phillips screw-driver.
▶Remove the cable binder from the rolled up cable.
▶Unroll the cable.
With the help of another person, lift up the cooling unit and turn it in the opposite coiling direction of the suction line (fig. 3 2, page 2), until the suction line is unrolled.

6.2 Installing the device

▶Observe the following installation instructions for the place of installation:

• Avoid placing the device next to heat sources such as heaters, gas ovens, hot water pipes, etc.
• Install the device in a dry, sheltered place.
• The device must be installed so that heated air from it can dissipate easily. Therefore make sure there is adequate ventilation (fig. 4, page 3).

No. in fig. 4, page 3	Explanation
1 Hot waste air
2 Cold intake air
3 Condenser
4 With decorative panel 50 mm space at the top!

▶ Fix the device with eight screws (fig. 5 1, page 3).

6.3 Removing the transport protection

The device has a locking mechanism to protect it during transport. The following settings are possible (fig. 6, page 4):

• Position 1 (transport lock): (1). The door is locked and secured. To open the door, turn the bolt to position 2.
• Position 2: (2). The door can be opened.
• Position 3 ("VENT" position): (3). The door is slightly open, but fixed in position. Use this position, for example, if you are not going to use the device for a long time.

6.4 Changing the door hinge

You can also change the hinge of the door, so that it opens to the left rather than the right.

To change the door hinge, proceed as follows (fig. 7, page 4):

▶ Remove the upper door hinge (1).
▶ Carefully lift out the door.
▶Remove the threaded pins (2).
▶ Pull the locking hook (3) off the rod.
▶ Remove the locking plate (4) and fit it on the opposite side.
▶ Pull the rod downwards and out and put it in the other side.
▶ Fasten the locking hook (3) back on the rod.
▶ Detach the top and bottom lock holders (5) on the left side.
▶ Detach the top and bottom door hinges (1) on the right side.

▶ Fasten the top and bottom door hinges (1) to the left side.
▶ Fasten the top and bottom lock holders (5) to the left side.

6.5 Connecting the device to a battery

NOTICE!

• To avoid voltage drops and loss of performance, keep the cable as short as possible and avoid joins. For this reason avoid additional switches, plugs or multi-way adapters.
• Disconnect the refrigerator and other electric loads from the battery before connecting the battery to a quick charging device. Overvoltage can damage the electronics of the device.
• Fit a fuse of at least 15 A to the positive connection.
• If possible, connect the device directly to the battery's pole.

For safety reasons the device is equipped with an electronic system to prevent polarity reversal. This protects the device against short-circuiting when it is connected to a battery.

MR07 and MRR07 only: To protect the battery, the device switches off automatically if the voltage is insufficient (see table below).

	12 V
Cut-off voltage	11.6 V
Cut-in voltage	12.1 V

▶Determine the required cross section of the cable in relation to the cable length according to fig. 8, page 5.

Key to fig. 8, page 5

Co-ordinate axis Meaning Unit

| Cable length m

∅Cable cross section mm²

NOTICE!

When connecting the battery, observe the correct polarity.

▶ Before starting up the device for the first time, check whether the operating voltage and the battery voltage match (see type plate).

MR07, MRR07

▶Connect the red cable to the positive pole of the battery.
▶Connect the black cable to the negative pole of the battery.

NOTE

The red/yellow cable is the starter cable for the device. When the red/yellow cable is switched to 12 V, the device is switched on.

▶ Connect the red/yellow cable to a switch (not included in the supply).
▶ Connect the other side of the switch to the positive connection.

MH07

▶ Connect the positive pole of the battery to the positive socket terminal block.
▶ Connect the negative pole of the battery to the negative socket terminal block.

7 Using the device

NOTICE!

The interior temperature of the device is affected by the ambient temperature.

• MR07 and MRR07 only: Observe that the set fixed temperature of 5 °C is fallen below, if the ambient temperature sinks to below 4 °C.
• Only MH07: Observe that the set fixed temperature of 37 °C is exceeded, if the ambient temperature rises to above 37 °C .

NOTE

Before using the device for the first time, clean it inside and out with a damp cloth for hygienic reasons (see also chapter "Cleaning and maintenance" on page 16).

7.1 Energy saving tips

• Choose a well ventilated location which is protected from direct sunlight.
• Do not open the device more often than necessary.
• Do not leave the door open for longer than necessary.
• MR07 and MRR07 only: Defrost your refrigerator as soon as a layer of ice forms.
• MR07 and MRR07 only: Clean dust and dirt from the condenser at regular intervals.

7.2 Using the device

NOTICE!

• The goods may only be stored in their original packaging or in suitable containers.
• Only put items in the refrigerator which can be cooled or heated to the selected temperature:
• MR07 and MRR07: 5 °C
• MH07: 37 °C

NOTE

MR07 and MRR07 only: After switching on, the refrigerator requires approx. 60 s until the compressor starts up.

Defrosting the refrigerator (MR07 and MRR07 only)

Humidity can form frost in the interior of the refrigerator or on the vaporiser. This reduces the cooling capacity. Defrost the device in good time to avoid this.

NOTICE!

Never use hard or sharp tools to remove ice or to loosen objects stuck to the device.

This is how to defrost the refrigerator:

▶Take the contents out.
▶If necessary, put them in another cooling device.
▶Leave the door open.

▶If you wish to drain the thawed water through a hose:
Connect a hose with an inside diameter of 6 mm to the outlet port (fig. 9 2, page 5).
▶ Remove the drain plug (fig. 9 1, page 5).
▶The thawed water now drains off through the hose.
▶Wipe the refrigerator dry with a cloth after thawing.

Switching off and storing the device

If you do not intend to use the device for a prolonged period, proceed as follows:

▶Disconnect the connecting cable from the battery.
▶ Clean the device (see chapter "Cleaning and maintenance" on page 16).
▶ Set the lock to the "VENT" position (see chapter "Removing the transport protection" on page 12).
This prevents odours from forming.

Securing the cabinet door

You can prevent the cabinet door from being opened inadvertently.

▶ Put the locking mechanism on the top of the door to position 1 (fig. 6 1, page 4).

8 Cleaning and maintenance

NOTICE!

Do not use abrasive cleaning agents or hard objects during cleaning as these can damage the device.

▶Clean the device regularly with a damp cloth once it becomes dirty.
▶Make sure that no water drips into the seals. This can damage the electronics.
▶If necessary, wipe up the condensation that has gathered on the floor.
▶Wipe the device dry with a cloth after cleaning.
