The cooling circuit is protected against unacceptable excessive pressure by
a type-tested pressostat. The switch interrupts the control voltage of the
compressor contactor. Restart is locked by the central control unit and
must be manually reset. Manipulation of safety switches is prohibited and is
a violation of UVV VBG20 (accident prevention regulations for cooling de-
vices). In any case, it will result in exclusion of warranty.
The high pressure pressostat is placed in the pipe of the refrigerant medium
at the exit of the condenser.

Fully hermetic compressors are equipped with a bimetal switch that dis-
connects the power supply and connects again after cool down to protect
against excessive motor temperatures; an error message is not generated.
Use only the specified oil type (ester oil ICI Emkarate RL 32-3MAF); non-
compliance will result in exclusion of warranty and certainly cause malfunc-
tions.
