LAMP REPLACEMENT AND QUARTZ CLEANING
Isolate from electrical and water supplies before removing the cover of
the unit.
Caution:
If the cover of the unit is wet, gently wipe away any water before
removing for servicing or maintenance. This will prevent water accidentally running
onto the electrical components.
Remove the cover and lift out the white plastic body. To dismantle the body, pull
off the white plastic lampholders at either end (see diagram) and slide the lamp out
carefully.
Next, unscrew the two compression fittings located at either end of the white
plastic body (see diagram) and slide off the two ‘O’ rings.
Then slide out the quartz sleeve. Clean the sleeve and polish with a soft cloth or
paper towel. If you live in a hard water area there may be some limescale on the
quartz sleeve. This can be easily removed by soaking the sleeve in a proprietary
kettle descaling solution. Failure to remove the limescale will limit the effectiveness
of the UV lamp.
ASSEMBLY PROCESS
Slide the quartz sleeve back into the white plastic body. Ensure that you locate
the ‘O’ rings accurately on the ends of the quartz. Failure to do so will result in
leaks when the water is turned on.
If you are carrying out the annual lamp change, use new ‘O’ rings. Firmly hand
tighten the compression fittings. Fit a new lamp. Relocate the lampholders and
place the unit back into the base.
Caution:
Ensure that the mains power cable is properly located in the cable slot
in the base (see no. 2 in diagram on page 6).
Caution:
Before replacing the cover ensure that the grey tubular gasket is
correctly located in the gasket recess in the base (see 3 in diagram on page 6).
Reconnect and turn on the water supply to check for leaks before connecting the
electricity supply. Replace the cover before switching the unit on.
Caution:
To achieve a proper seal, ensure that the three cover fixing screws are
fully tightened, securing the cover to the base.
IMPORTANT
The plastic body and any hosetails supplied with this unit are manufactured from
polymers that have been specifically stabilised, to protect them from the effects
of UVC light emitted from the lamp. Despite this UV protection the plastic body
and hosetails will be eroded by the UVC and the water flow. As a matter of
course they should be inspected whenever a lamp change is carried out, to ensure
that they are not showing excessive wear and tear. Low cost replacements are
available from your local aquatic supplier.
