(that is, of the water obtained from
melting ice during automatic or
manual defrosting cycles)
4) The compressor never stops or
remains in function for very long
periods of time
5) The light does not work
LIKELY CAUSES
a) the outlet pipe for defrost water,
which goes from the water drip to the
condensate tray, is blocked
b) the display unit has been incor-
rectly levelled (i.e., unevenly) and
the water cannot flow towards the
outlet hole
a) the ambient temperature is too
high
b) the air condenser is blocked
c) the evaporator is blocked by ice
d) the thermostat is set at a tempera-
ture which is too low
e) there is a partial lack of gas
a) the light switch circuit has not
been enabled
b) the fluorescent lamp has not been
correctly inserted into the fittings
c) the lamp has reached the end of
its useful life
d) the malfunction persists
FOR ALL THESE OPERATIONS SEE
PARAGRAPH 5.1
POSSIBLE SOLUTIONS
a) unblock the outlet pipe
b) level the display unit as described
in Section 2.4. The unit must be
perfectly level
a) if it is not possible to reduce
ambient temperature (for example,
with an air conditioning system),
the compressor must work almost
continually
b) clean the condenser as shown in
Section 4.2
c) defrost the unit as indicated in
Section 4.4
d) set the thermostat to a higher
temperature, as indicated in Sec-
tion 3.2
e) call the Technical Assistance Ser-
vice to detect the cause of the gas
leak and only after having solved

cording to the quality and quantity
of gas shown on the plate
a) turn off the light switch
