ROUTINE MAINTENANCE

UV Bulb Replacement

ALWAYS ISOLATE THE UNIT FROM ANY ELECTRICITY AND WATER SUPPLIES

BEFORE CARRYING OUT MAINTENANCE ON THE UNIT.

To Change the Bulb:

It is not necessary to stop the water circulating through the evoUV to change the bulb.

1. On the side that you wish to pull the UV bulb out, slacken off the gland nut on the end

cap to release the cable.

2. Unscrew the end cap taking care not to lose the end cap sealing ring.

3. Disconnect the bulb socket.

4. With the end cap out of the way, carefully slide out the UV bulb. (You may need to pull

firmly on the bulb in order to disconnect it from the bulb socket at the other end.)

5. Slide in the new UV bulb gently turning the bulb until the pins locate in the bulb socket

at the closed end of the unit.

If you have difficulty locating the pins, you can remove the end caps at both ends to

make replacing the bulb easier.

6. Once you have attached the bulb socket, replace the end cap ensuring the end cap

sealing ring is located correctly.

7. Replace the gland nut sleeve and tighten up the gland nut.

WARNING: If the end caps / electrical connections get wet during this procedure,

please ensure that they are thoroughly dried before re-connecting.

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.

evo110 Bulbs Only:

If only one bulb lights up on the evo110 you should

carry out some initial checks to ascertain if the UV

bulb has failed.

• Swap over the end connectors on each bulb at one

end of the evoUV.

• Check that the end connectors are completely dry

and are connected properly.

• Replace the UV bulb.

At one end

of the

evo110 only.
