Tese canes are caused by te followin main components: Compressor Te compressor (M*C) acts as a pump and circulates te refrierant in te refrieration circuit. It compresses te refrierant vapour comin from te evaporator at te pressure at wic it can easily be liuefied in te condenser. Condenser Te function of te condenser is to cane te state of te refrierant from aseous to liuid. Te eat ained by te as in te evaporator is discared trou te condenser to te ambient air, and te vapour condenses to liuid. Filter/drier Te filter installed beind te condenser removes small particles from te refrierant to prevent blockae of te tubes. Te drier takes water out of te system. Safety devices Te unit is euipped wit two kinds of safety device: 1 General safety devices General safety devices sut down all circuits and stop te wole unit. For tis reason te unit as to be manually put on aain after a eneral safety occurred. 2 Part safety devices Part safety devices sut down te part tey protect. An overview of all safety devices is iven below. Overcurrent relay Te overcurrent relays (K*S) are located in te switcbox of te unit and protect te compressor motors in case of overload, pase failure or too low voltae. Te relays are factory-set and may not be adjusted. Wen activated, tey must be reset manually, followed by a reset of te controller. Compressor termal protectors Te compressor motors are euipped wit termal protectors (Q*M). Te protectors are activated wen te compressor motor temperature becomes too i. Wen temperature returns to normal, te protectors reset automatically, but te controller needs to be reset manually. Fan motor termal protector Te condenser fan motors are euipped wit termal protectors (Q*F). Te protectors are activated wen te temperature becomes too i. Wen temperature returns to normal, te protectors reset automatically. Discare termal protectors Te unit is euipped wit discare termal protectors (S*T). Te protectors are activated wen te temperature of te refrierant leavin te compressor becomes too i. Wen te temperature returns to normal te protector resets automatically and te controller needs to be reset manually. Low pressure safety Wen te suction pressure of a circuit is too low, te circuit controller suts down te circuit. Wen te pressure returns to normal, te safety device can be reset on te controller. Pressure relief safety valve Te safety valve is activated wen te pressure in te refrierant circuit becomes too i. If tis occurs, sut down te unit and contact your local dealer. 3

5 Hi pressure switc Eac circuit is protected by two i pressure switces (S*PH) wic measure te condenser pressure (pressure at te outlet of te compressor). Tey are installed in te compressor ousin of te circuit. Wen te pressure becomes too i, te pressure switces are activated and te circuit stops. Te switces are factory-set and may not be adjusted. Wen activated, tey must be reset by means of a screwdriver. Te controller still needs to be reset. Reverse pase protector Te reverse pase protectors (R*P) prevent te screw compressors from runnin in te wron direction. If te compressors do not start, two pases of te power supply must be inverted.
