Technical description
The CoolFreeze compressor cooler MC-045 (Ref. No. 9105100004) is suita-
ble for use with 12 V DC voltage.
The compressor cooler can cool goods down to a constant temperature of
5 °C and keep them cool.
All materials used in the compressor cooler are compatible for use with food-
stuffs. The refrigerant circuit is maintenance-free.
The device is fitted with a cooling unit which can be installed separately
(fig. 1, page 3).

Automatic safety circuit
If the temperature in the interior exceeds 55 °C, the compressor cooler
switches off automatically.
Once the temperature falls below 55 °C, the compressor cooler switches on
again automatically (On/Off switch will remain in the On position).
The automatic safety circuit also monitors the activation of the compressor
cooler, which is only possible at a maximum temperature of 55 °C.
5.3
Low voltage shutdown
The low voltage shutdown switches the compressor cooler off automatically
when the on-board voltage falls below 10.6 V. This prevents the vehicle bat-
tery from discharging.
The compressor cooler switches on again automatically when the on-board
voltage rises above 11.9 V, e. g. after starting the vehicle.
