6. MAINTENANCE: __________________________________________________________________________________________________
Prior to the installation or replacement of any system component make sure it has been
previously disconnected from the mains, and there is no water flow through it. Use only spare
parts supplied by AstralPool.
Do not handle the UV lamp until completely cold.
6.1. Replacement of the UV lamp
FREQUENCY:

The replacement of the UV lamp should be done whenever the system RADIATION ALARM was active, and cleaning with the reactor
manual device was not effective.

When COMBINED CHLORINE levels in the pool are abnormally high.
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.
9.- Screw the lock nuts on both sides of the lamp.
10.- Remount the front of the connection boxes in its original position so that it is properly fixed with the screws.
Warning
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:
To access the "Configuration" screen, press the "Diagnostics" button. The system accesses the diagnostic screens both
of the electronic ballast and the UV lamp power circuit discussed in Section 5.6.
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 (MP 450, MP 675), 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.
