6.1Removing 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.
6.2Installing 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).

Explanation
6.3Removing 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.
6.4Changing 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.

6.5Connecting the device to a battery
NOTICE!
A
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).
• 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.

7Using the device
NOTICE!
A
The interior temperature of the device is affected by the ambient
temperature.
• MR 07 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).

MR07, MRR07, MH07Using the device
7.1Energy 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.
7.2Using the device
NOTICE!
A
I
• 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:
– MR 07 and MRR07: 5°C
– MH 07: 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!
A
This is how to defrost the refrigerator:
➤ Take the contents out.
➤ If necessary, put them in another cooling device.
➤ Leave the door open.
Never use hard or sharp tools to remove ice or to loosen objects stuck to
the device.

Cleaning and maintenanceMR07, MRR07, MH07
➤ 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 protec-
tion” 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).
8Cleaning and maintenance
NOTICE!
A
➤ Clean the device regularly with a damp cloth once it becomes dirty.
