When the unit is deactivated using the remote
control panel, power remains on to preheat com-
pressor oil and operate the frost protection heater.
At every change of season, make sure the oper-
ating conditions fall within the limits specified on
page 21.
Make sure the current absorption of the com-
pressor is less than the maximum given in the table
of technical data.
In the case of three-phase models, if compres-
sor noise levels are abnormal, reverse one of the
phases.
Make sure the voltage is within the established
limits and that, for three phase units, the unbalance
between the phases is less than 3%.
