Konfort Series 700R Service Manual
C. The compressor does not start
Replace the capacitor and the starter of the compressor (cod.
4800022 and cod. 4800026).
Check, with the help of a multimeter, the continuity of thermal
protection (overload, cod. 4800027) inside the electrical connection
box of the compressor. If the problem would persist, replace the
complete recovery group (or the only compressor on Konfort 705R).
Check the continuity of fuses F1 and F3 located on the ACE Power
board (see Appendix 2). If they would be interrupted, replace them
with two new ones with appropriate features (250V – T10A). If the
problem would persist, replace the complete ACE Power board.
Check that the plug of the power supply network will provide a
correct voltage (~ 230V – 50Hz).
Check that an alternate voltage of 230V will be present at input of the
compressor. Check this value between pin CO and its corresponding
neutral pin N on the ACE Power board (see Appendix 2).
7.5
The unit does not perform the vacuum
A. The vacuum pump does not start
Try to manually start the vacuum pump from the Power outputs
function. If it would not start, check the presence of the power supply
network voltage (~ 230V – 50Hz) between the pin PO and the neutral
pin N of the ACE Power board (see Appendix 2). If the voltage would
not be correct, replace the ACE Power board.
If the pump starts for about 3 minutes and then stops, check the
continuity of the thermal relay located into the box above the pump
(which contains the electrical part of the pump itself). If the problem
would persist, replace the thermal relay.
Remove the power supply cable of the equipment from the power
supply network plug, remove the protective cover of the fan of the
vacuum pump and try to rotate the shaft with the hand, in order to
check that it will be able to rotate freely. In case it would be blocked,
proceed with the replacement of the vacuum pump.
