Procedure:
1. Remove the front of the lamp connection boxes
releasing the four screws that fix it to the body
of the UV reactor.
2. Disconnect the lamp from the terminals of the
two connection boxes.
3. Release the lock nuts on both sides of the lamp.
4. Remove the Teflon
™
end caps on both sides of
the quartz sleeve.
5. Completely extract the lamp holding it from one
of the ceramic ends, so that it does not suffer
any stress.
WARNING
Always handle the UV lamp with gloves, as fat and other impurities
deposited on the surface may reduce its performance and durability.
In case you have to clean the lamp surface use a soft cloth soaked
with alcohol.
6. Insert the new lamp, holding it always from one
of the ceramic ends, and insert it back into the
quartz sleeve without stress.
7. Place in its original position the Teflon end caps
on both sides of the quartz sleeve.
8. Screw the lock nuts on both sides of the lamp.
9. Remount the front of the connection boxes in its
original position so that it is properly fixed with
the screws.
Whenever the lamp is replaced, the unit hour meter
must be reset. To do this, reconnect the system
with the switch on the front of the control panel, and
proceed as follows:

“Configuration”
screen,
press the

Pressing the navigation key at the top right
of the screen, you will access to the
“Lamp
Reset”
screen. In the case of multiple-lamp
systems (MP450W), the screen corresponding
to the lamp replaced should be selected.
Perform this procedure on all the screens, in
the case of replacing all the lamps of the unit.
This screen allows to reset the operation hour
meter and the number of ignitions of the lamp
each time it is replaced by a new one.
To do this, click on the activation code and using the
pop-up keyboard, enter the code
“1234”
.
Press the
“Reset”
key to confirm.
The timer will now show
“0”
