9.1 Notes on servicing

DANGER

Risk of electric shock

Working on the device when voltage is applied can lead to electric shock.

Isolate the device from the power supply prior to starting any work.
Safeguard against accidental restart.

WARNING

Electric shock caused by frequency converter

It is possible that electrical components continue to carry voltage and cause elec-
tric shock even after the voltage supply has been disconnected.

Wait approx. 5 minutes before commencing work.
Electric voltage has dissipated.

WARNING

Danger of getting burned on hot components

Hot components can lead to burns.

Allow components to cool.

Servicing must only be carried out by qualified personnel. The combustion plant
should be serviced annually. Depending on site conditions more frequent checks
may be required.

Components, which show increased wear and tear or whose design lifespan is or
will be exceeded prior to the next service should be replaced as a precaution.

Weishaupt recommends a service contract is entered into to ensure regular in-
spections.

The following components must only be replaced and must not be repaired:

combustion manager
flame sensor
actuator
oil solenoid valve
nozzle head,
pressure switch,
oil nozzle.

Prior to every servicing

Inform the operator about the extent of service work to be carried out.
Switch off mains switch of installation and safeguard against accidental reactiva-
tion.
Close fuel shut off devices.

Following servicing

Check tightness of oil carrying components.
Check function of:

ignition,
flame monitoring,
oil pump (pump pressure and suction resistance),
Pressure switch
control and safety devices.

Check combustion values, if necessary re-adjust the burner.
Enter combustion values and settings in the commissioning record and/or test
sheet.
