ROUTINE MAINTENANCE
UV Bulb Replacement
ALWAYS ISOLATE THE UNIT FROM ANY ELECTRICITY AND WATER SUPPLIES
BEFORE CARRYING OUT MAINTENANCE ON THE UNIT.
PLEASE NOTE: The evo110 model has been specifically designed so that if either
bulb fails, both will go out. This enables you to quickly identify and replace the bulb
which is not working. Otherwise you may not notice that a bulb has failed, and that
your unit is effectively only working at half its potential level of output.
Evolution Aqua’s UV Bulbs are manufactured to the highest standards, as such it is
rare that a bulb fails. If this happens to you we would strongly recommend that you
replace both bulbs in the evo110. See page 14.
To Change the Bulb:
1. Unscrew a gland nut from one end of the evoUV. This will be the end where you
intend to remove the UV bulb.
2. Unscrew the end cap from the same end of the evoUV and slide the end cap
down the cable.
3. Gently pull the bulb socket away from the UV bulb at the exposed end,
taking care not to disturb the quartz sleeve.
4. Carefully take the old bulb out, taking care not to disturb the quartz sleeve.
5. Replace the new bulb by sliding it carefully into the quartz sleeve. Ensure that all
connectors are dry.
PLEASE NOTE: Make sure that the two pins on the end of the bulb locate into
the bulb socket at the closed end of the evoUV. You should feel the pins click
into position. Once you have felt the bulb click into position, the bulb is engaged.
WARNING: If the end caps / electrical connections get wet during this procedure,
please ensure that they are thoroughly dried before re-connecting.
6. Reconnect the bulb socket.
7. Screw the end cap back on – FINGER TIGHT ONLY.
8. Tighten up the gland nut and sleeve – FINGER TIGHT ONLY.
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.
