Monthly on FBM 1P, FBM 2 and FBM 3 models: remove
the dust from the condenser filter. A blocked filter will reduce
performance and could cause compressor failure.
Remove the only left panel (from faucet side) unscrewing the
two plastic coated screws (see figure 16).
ATTENTION
Condenser fins are very sharp. Use extreme caution
when cleaning.

Replacement of lighted top cover bulb: remove the fixing
screw placed in the upper part of the top cover, remove the
lower part and replace the bulb (using a 24-28V 21W max
bulb). Reassemble the top cover and replace the fixing
screw.(see figure 17)

7 DEFROST TIMER

The Defrost Timer, located on the right side of the unit,
automatically switches the dispenser from Granita mode to Soft
Drink mode and the opposite. This means that during defrost
periods frozen Granita will melt to thermostat setting
temperature and once defrost period has expired, the product
automatically freezes down again to Granita setting viscosity.
To operate the defrost timer proceed as follows (see figure 18).
1
Set the time of the day by rotating the dial clockwise (arrow
A). Never rotate the timer counterclockwise as this would
damage the internal mechanism. Align the current time of day
with the arrow B on the timer face. This is a 24 hour timer
showing both A.M. and P.M.
2
Program the defrost timer by pushing out on the tabs C that
correspond to the hours desired to defrost. Each tab represents
15 minutes. A minimum of four to eight hours are required to
defrost frozen beverage (depending on ambient conditions).
Note: when all the tabs are pushed in the defrost function is OFF
(the machine operates as if it were not equipped with Defrost
Timer).
