6. ORDINARY MAINTENANCE
The appliance must be regularly serviced (at least once a
year) by a qualified UNOX service technician.
Any maintenance operations must be carried only by a
qualified UNOX technician. Before starting any maintenance operation, it is necessary
to disconnect the appliance from the electrical power
supply and allow it to cool down.
The service is needed on:
Combustion
To check if the combustion is correctly made an unburnt
meter (like TESTO 300M or similar) is required. In the
combustion exhaust fumes the percentages of CO in ppm
and of CO2 must be below the maximum values allowed
by the regulations (approx. the CO value must be below
300 ppm).
If the CO value is over le maximum level allowed, pro-
ceed with the further check over described here below
to find out the cause of the problem.
Condition of the of the burner flame surface
Remove the burner box from the back of the oven, open it
by removing the upper cover and check the burner surface
is clean and free from any dirt by.
Check the burner surface is not damaged or cracked, oth-
erwise, in case of damage, it is necessary to find out and re-
move the cause of the problem (too high gas pressure, gas
injector not suitable for the type of gas on use, oven placed
on a non flat surface, water leakage on the burner surface,
etc.) and to have immediately the burner replaced.
Condition of the heat exchanger
Check the heat exchangers are not strained, cracked or
damaged, otherwise it is necessary to remove the cause
of the damage (too high gas pressure, gas injector not
suitable for the type of gas on use, oven placed on a non
flat surface, water leakage on the burner surface, etc.)
and to have immediately the heat exchangers replaced.
Condition of the baffles
Check the baffles are not damaged or cracked by taking
them out from the heat exchangers and check also there
is no soot on them. In case of cracks or soot on the baffles
it is necessary to find out and remove the cause (too high
gas pressure, gas injector not suitable for the type of gas
on use, oven placed on a non flat surface, water leakage
on the burner surface, etc.) and to have immediately the
baffles replaced.
Once the check over and the replacements described
here above have been made repeat the check on the
combustion.
6.1 REPLACEMENT OF THE INTERNAL LAMP
To replace the internal lamp:
• disconnect the appliance from the power supply and
allow it cool down.
• remove the lateral supports
• unscrew the glass cover and replace the lamp with
one with the same characteristics.
• Inspect the lamp glass seal and replace if required.
• screw the glass cover back in
• reassemble the lateral supports
7. SPECIAL MAINTENANCE
All maintenance operations must be only be carried out
by a qualified UNOX technician.
Before starting any maintenance operation it is necessary
to disconnect the appliance from the electrical power
supply and allow it to cool down.
Removal of the back panel will allow access to all internal
components for service and maintenance.
