TO REMOVE A UV BULB:
It is not necessary to stop the water circulating through the UV to change the bulb.
1.
Disconnect the electricity supply.
2.
Unscrew the black end cap at one end of the unit. Take care not to unscrew the white
locking nut also.
3.
Carefully slide the black end cap over the wire to reveal the bulb socket.
Take care not to lose the end cap flat washer.
4.
Disconnect the bulb socket.
5.
Repeat steps 2 to 4 at the other end of the UV.
6.
With the end caps out of the way, carefully slide out the UV bulb.
WARNING:
If the end caps / electrical connections get wet during this procedure,
please ensure that they are thoroughly dried before re-connecting.
TO INSTALL A NEW UV BULB:
Follow the instructions on
page 16
to fit a new UV bulb.
IMPORTANT:
After checking all the fittings are correctly tightened you can switch your unit
back on.
As already mentioned, it is essential that the unit is protected from frost during the winter
months, or disconnected from water and electricity supplies and stored indoors. During
the spring and summer season, the quartz sleeve, which separates the UV bulb from the
water passing through the unit, will need to be cleaned two or three times. This is essential,
as dirt or limescale building up on the quartz sleeve will inhibit the penetration of the
ultraviolet light into the water and affect the efficient working of the unit.
UV BULB REPLACEMENT
ALWAYS ISOLATE THE UNIT FROM ANY ELECTRICITY AND WATER SUPPLY
