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 below).
Caution:
Before replacing the cover ensure that the tubular gasket is
correctly located in the gasket recess in the base (see no.3 in diagram below).
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 two 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.
