Technical description
The cooling units are suitable for use with 12 V or 24 V DC voltage and can
therefore be used for camping or on boats. Furthermore, you can connect
them to a 230 V mains supply via the WAECO rectifiers (see chapter “Acces-
sories” on page 38).
When used on boats, the cooling unit can withstand a constant heeling of
30°.
This refrigerant circuit is CFC-free.
The cooling unit must be used together with a vaporiser. In addition, you can
use an accumulator with or without TEC control. The
CS-NC15
comprises a
cooling unit and a vaporiser.
Use the continuously variable thermostat on the vaporiser to set the desired
temperature.
The accumulator and TEC program control ensure a high cooling capacity
and improve the unit’s efficiency. The accumulator is charged when there is
a sufficient supply of power (for example when powered by a mains adapter).
In the event of accumulator usage or under-voltage, the coolant is drawn
from the accumulator until it is empty. Thus, no power is taken from the bat-
tery during this time.
The TEC program control always ensures that
z
Cold energy is stored if there is excess electrical energy (external supply
of power by a generator).
z
The coolant accumulator can be used at any time to ensure that the com-
plete battery power is used for other consumers.
z
Stored cold energy is automatically retrieved to preserve the interior
cooling temperature of the cooling area, once the battery capacity is
exhausted.

Note
Further information on the coolant accumulator can be found in
chapter “Use coolant accumulator” on page 48.
