Caution
It is important that the supplied drain trap with ball is fitted before commissioning.
11.1.2 Control panel and automatic controls
The automatic controls cabinet is supplied as an integrated part of the cooling box, with a door for inspection and serv-
ice work. This is possible to access during normal operating conditions for the unit. There are also nipples for refilling
and checking the pressures in the cooling circuits. The cabinet is equipped with an approved control panel lock and must
only be opened by authorised personnel.

The main components of the cooling system are:
1. Condenser battery
2. Evaporator battery
3. Compressor
4. High pressure switch
5. Low pressure switch
6. Electronic expansion valve
7. Filter drier
8. Sight glass
9. Ball valve
10.Angle valves
The cooling process is either carried out using one compressor. When required, compressors starts so that the refriger-
ant is compressed and transported to the condenser; the refrigerant is cooled in the condenser using extract air and
then takes on liquid form. The refrigerant then continues to the expansion valve, and reduces pressure and temperature
over that, before continuing to the evaporator (DX battery). The liquid evaporates in the DX battery and simultaneously
cools the external air. The refrigerant then moves on to the suction side of the compressor and the process is repeated.
11.2.1 Other regulation
Geniox Softcooler is always equipped with a frequency-controlled compressor, i.e. the cooling effect is adapted to the
need, either due to variable (low) air volumes or variable (low) outdoor temperatures, or a combination of these. This
ensures a more stable operation and energy-saving cooling in relation to ON/OFF solutions. Regulation of the compres-
sor(s) is thus as follows:
When system gets start signal, the compressor will ramp up quickly to 100Hz and work that stage for certain amount of
time. After time passed, system will start to regulate compressor speed according to reference signal from main con-
troller (0–10V).
In case of alarm, either from the pressostats or frequency converter, frequency converter will stop and alarm output will
be activated.
In case of alarm, see chapter 10 in this document.
