PERIODICAL FAN MAINTENANCE
Type 1÷4
The motor is connected directly to the fan shaft.
The fan motor does not need any maintenance, but only periodical cleaning.
Type 5÷7
Cleaning the centrifugal fan requires mechanical removal
of dust and of any extraneous bodies deposited on or near
the rotor.
Periodically check the transmission belt tension. When
pressing at the centre, it should deflect by approximately
20mm. Adjust if necessary as follows:
•
Turn the generator off by setting the main switch on
the control panel to “OFF”.
•
Remove the protection grille.
•
Slacken the four nuts (
3
) that fasten the motor
support.
•
Tighten the belt (
1
)
by acting on the screws (
2
),
until, when pressing at the centre, the belt deflects
approximately 20mm.
•
Tighten the four nuts (
3
) to fasten the motor
support.
Check that the motor and fan pulleys are aligned
correctly.
For these models too the fan motor does not require
maintenance but only periodical cleaning of the protective
cover of the cooling fan.
Type 5÷7
THERMOSTATS
The thermostats do not require maintenance save normal
cleaning of the external parts of the sensitive elements.
The LIMIT thermostats have fixed settings and
must not be tampered with.
The
FAN
thermostats
are
pre-set
during
manufacture and we suggest you do NOT adjust
their settings.
The manufacturer is not responsible for any damage
caused by improper actions on the thermostats.
BURNER CLEANING
For burner cleaning, refer to the instructions in the burner manual.
