Victoria Arduino BLACK EAGLE VA388 Service Manual page 71

The holes of the injector tend to become clogged
if the operating water is not optimally softened or
after several months of work.
For this reason, we recommend that the injectors
be replaced once a year.
To remove the injectors it is necessary to drain
the heater as shown in section 6.3 and then care-
fully unscrew the injector from its housing using a
No. 14 wrench or 14 mm spanner.
NOTE
Be extremely cautious during removal opera-
tions since the ceramic heating elements
insulators could be damaged thus compro-
mising the integrity of the entire heater.
If the ceramic insulators break the heater
must be replaced to prevent a general short
circuit.
REASSEMBLY
Wrap the threading of the injector with Teflon
tape or use of liquid Loctite before screwing the
component into its housing.
