Test run
Start the refrigeration unit by selecting NORMAL.AUTO
working mode. The green indicator light comes on
immediately and the yellow one shortly after indicating that
the compressor is running on low speed. Shortly after, a slight
hissing sound can be heard from the holding plate, which
after 15 – 30 minutes will show signs of moisture or frost.
Start the engine. Within 1-10 minutes, depending on
conditions of the batteries and alternator, the yellow light will
go out and the red light will come on and the compressor is
speeding up.

When the engine is stopped, the voltage in the electrical
system drops, within a few minutes the yellow light comes
on, the red goes out and the speed of the compressor is
reduced.
If the holding plate has reached its full refrigeration capacity,
however, the compressor will stop instead. There is always
a 30 second delay before the electronic monitoring system
takes over.
Finally, check that the electrical wiring and pipework are safe
and securely fastened.
Check also all water connections, hose clamps and adaptors.
