Caution!
When you are discharging the accumulator, although there is an
external supply of power – for example to avoid operating noise
from the compressor – use the main switch to switch the unit off
(
1
B1 or
2
6, page 3).
Please remember: Low internal temperature = high current
consumption!

Explanation
1
Green LED: indicates that the compressor is working.
2
Yellow LED: indicates that the external power supply is
present (voltage is higher than 13.5 V or 27.0 V).
The LED flashes if the external power supply is too low
(voltage
≤
10.7 V or 21.7 V. Version E:
≤
10.7 V or 22.0 V).
3
Red LED: indicates that the accumulator is being discharged
because
z
the discharge button has been pressed
z
Low voltage shutdown (voltage
≤
10.7 V or 21.4 V. Version
E:
≤
10.7 V or 22.0 V).
4
Accumulator discharge button: interrupts compressor
operation until
z
the stored cold energy is exhausted
z
The external supply voltage level is restored after
low voltage.
5
Temperature selector: allows the temperature in the cooling
area to be set as required
Min. (left limit) = warmest setting
Max. (right limit) = coldest setting
6
Main switch: for switching the cooling device on and off.
Position 0 = OFF
Position - = ON
