Switch cabinet
The switch cabinet is fully installed, connected and complies with the technical requirements of the VDE 0113.
For parts see circuit diagram.
The unit is switched on by means of the master switch.
When the master switch is turned to Pos. 1 the water pump is started and, should the thermostat require
cooling, the compressor is turned on.
In order to prevent the compressor from being switched on for short intervals, the time-delay relay hinders the
start procedure. After the time has passed by and the compressor has been at a standstill, i.e. after a pause of
approx. 1 minute, the refrigeration process will commence immediately if the thermostat has switched it on.

First-aid measures
o
After inhalation: Bring the afflicted person into fresh air and position them comfortably while protecting
yourself. Call doctor. Commence mouth-to-mouth resuscitation if breathing has stopped.
o
After skin contact: First leave the caked clothing on the skin. Rinse the cold-damaged areas with lukewarm

o
Notes for the doctor: Do not administer catecholamine or adrenaline-ephedrine medications.
Measures for fire-fighting
o
Suitable extinguishing agent: Product that does not burn itself. Coordinate extinguishing measures to
surrounding fire. Cool containers by spraying with water.
o
Special dangers from the material, its combustion products or emerging gases: Dangerous gases and vapours
build during pyrolysis.
o
Special protective equipment for fire fighting: Independent breathing apparatus and acid-resistant protective
suit with deployment in the immediate vicinity.
