Before removing the protective plastic cover from the electrical components, check if the compressor is
disconnected from the mains and that starting and / or running capacitors are used.
Never handle any electrical accessory with the compressor connected to the mains.
Failure to shut down the mains compressor during maintenance procedures and to apply
a system without a ground fault circuit interrupter (GFCI) or residual current device (RCD),
according to the country technical requirements, may cause serious physical hazards by
electric shock and/or fire to the technician.
Starting and / or running capacitors must be handled with care, as they may cause
electric shock even when disconnected.
When it is necessary to remove the capacitors, carefully disconnect these components with extra attention to the
exposed electrical terminals. The capacitor must be discharged before handling.
Check that the capacitance range (μF) printed on the starting and running capacitor label (if applicable) comply
with the compressor data sheet that is installed in the system.
The ACV Voltage value printed on the capacitor label must be equal to or greater than the value specified in the
compressor data sheet. If one of the values (ACV Voltage and / or Capacitance) is not in accordance with the
compressor specification, replace the capacitor.
Application of an unsuitable capacitor and / or application of unspecified relay starting
devices may cause the capacitor to overheat. Overheated capacitors are subject to
rupture which can lead to leakage of overheated material that can lead to burns.
When necessary to disconnect the electrical components of the hermetic compressor terminal, remove the relay
starting device by applying longitudinal effort to the pins. Never apply transverse forces to the pins of the hermetic
compressor terminal
Improper removal of these accessories may cause poor electrical connection, damaging
the hermetic compressor terminal, and causing refrigerant and oil leakage.
Compare the printed code on the relay with the compressor data sheet. If the code is different, replace the
component. There are no universal or similar electrical accessories always use the one specified in the compressor's
data sheet.
WARNING
Failure to disconnect the compressor from the mains may, in the event of a short circuit
in the region of the hermetic terminal of the compressor, cause expulsion of the hermetic
pins causing leakage of the cooling fluid.
