7 Additional Equipment
7.1 Battery
• The alarm functions described in chapter 5, are supplied by a 12V battery situated in the compressor
compartment.
• This battery is recharged automatically, when the unit is connected to a power source.
• The battery should be replaced every 2 years as a precaution. The battery replacement should only be
carried out by an authorized service engineer. The load must be removed and the unit must be switched off
before the battery is replaced.
• The rechargeable battery is a lead accumulator which, if defective, must be disposed of separately.
7.2 Automatic Defrost
• The MT100 is equipped with an automatic defrost function. After a run time of 8 hours, the compressor is
switched off until the evaporator temperature r4°C. If this temperature is not achieved after a
timeout of 20 minutes, the appliance is switched on again.
• During the automatic defrost, the defrosting symbol is shown in the display.
7.3 Inner fan
• The device is equipped with an internal ventilation system and it is vital that the interior fan is always
operational.
• To prevent warm outside air being sucked into the unit unnecessarily during a door opening, the fan
switches off automatically, while the door is opened.
• The airflow to the fan must never be impeded. The ventilation slots must therefore never be blocked or
covered.
7.4 Fuses
• In both operation modes, DC and AC, the equipment is
protected by fuses, which can be located at the back of
the compressor compartment.
• In case of a defect, the fuses may only be replaced by
an identical part.
7.5 Remote Temperature Alarm
• There are 3 potential free contacts on the back of the
unit that can be used to trigger an additional
remotetemperature alarm (visual or audible).
• Muting the buzzer in a temperature alarm situation only
switches off the internal audible alarm. The key does
not interfere with the external alarm. The external alarm
signal is only switched off once the cause of the alarm
has been eliminated.
• A max Voltage of 30V AC or 60V DC can be connected
to the contacts. The maximum load must not exceed 8A.
The minimum power rating is 500mA / 12V AC.
