SPECIAL MAINTENANCE

ATTENTION: To guarantee peak cooling

system performance, the routine cleaning of

the condenser filter is essential.

As explained earlier, an audible signal accompanied by

the word FILT appearing on the control panel display,

will warn the operator when the filter is clogged and so

must be cleaned before the machine comes to an

automatic stop.

• Disconnect the machine from the power supply;

• Unscrew the nut (C in FIGURE 30).

• Remove the cover (B in FIGURE 30).

• Disconnect the plug (D in FIGURE 31).

• Loosen and rotate the bracket.

• Lift and remove the back (E in FIGURE 31).

• Clean the filter behind the net, then clean the

condenser with a brush, if necessary.

WARRNING: You are reminded that all the opera-

tions described above must be carried out with

the machine switched off and the power cable dis-

connected.
