WARNING!
The coolant in the system is under pressure.
Wear safety goggles and gloves when disconnecting.
If the device must be decoupled for return shipping, make sure to screw the
caps back onto the coupling halves to prevent dirt and moisture from entering
the refrigerant circuit.
6.4 Connecting the cooling unit
Connecting to a battery
The cooling unit can be operated from a 12 V or a 24 V DC voltage supply.

NOTICE!
To avoid voltage loss and therefore a drop in performance, the
cable should be kept as short as possible and should not be inter-
rupted.
For this reason avoid additional switches, plugs or power strips.
➤ Determine the required cross section of the cable in relation to the cable
length according to fig. i, page 9.

NOTICE!
Make sure that the polarity is correct.
➤ Before you start up the unit for the first time, check that the
operatingvoltage matches the battery voltage (see type plate).
➤ Connect your cooling unit
– as directly as possible to the pole of the battery or
– to a plug socket which is fuse protected with at least 15 A (at 12 V)
or 7.5 A (at 24 V).
