7.1
Replacing the UV lamp:
Warning: The appliance must be disconnected from
the power supply before disconnecting the UV-C
emitter.
A UV lamp’s effectiveness reduces significantly over
time so you should replace your lamp every 12 months
even if the lamp is still functioning.
7.1.1 Switch off the power to the supply pump and filter.
7.1.2 Turn the diverter valve to waste. This allows the
internal pressure to equalise with atmospheric pressure
and allows easy removal of the electrical housing
without water being drawn up onto the top surface of
the lid.
7.1.3 Wind the cleaning handle by half a turn so that it is out
of the way of the electrical housing (Fig. 16 (i)).
7.1.4 Use a screwdriver to remove the 5 screws which secure
the electrical housing to the lid. (Fig 16 (ii)). There is a
pocket provided between the filter’s inlet and outlet
to store the screws while you change the lamp (Fig. 16
(iii)).

7.1.5 grip the electrical housing and gently pull up to remove
the electrical housing. Turn the housing upside down
and place on a dry level surface.

(Fig. 17) Unscrew the quartz tube
locking collar (i). gently hold the
quartz tube (ii), lift up and remove
together with its o-rings (iii) and
locking collar.
7.1.7
remove the old lamp by gently
pulling it from its holder and
remove the black protection cap
from the end of the lamp (Fig.
17 (iv)) and remove the reflector
plate (Fig. 17 (v)). Dispose of
the old lamp according to local
regulations and fit the new lamp.
7.1.8
refit the reflector plate and push
the black cap on to the end of the
lamp.
7.1.9 Slide the quartz tube down over the lamp. Ensure that
the two o-rings at the base of the quartz tube are clean
and free from debris.
7.1.10 Slide the locking collar down over the quartz tube and
screw down. You should screw down until the stop of
the locking collar hits the stop of the housing so that
the collar cannot be screwed down any more.
7.1.11 refit the electrical housing. The housing can only be
fitted in one position so do not try to force it down.
once in position, replace the 5 screws. The screws must
be fully screwed down to ensure that the interlock
switch is activated.
7.1.12 Turn the diverter valve back to pond and position the
cleaning handle in the stowage position.
7.1.13 re-start the pump first checking for leaks, then switch
on the UV lamp. Check for the bluish glow from UV
indicator lens.
7.2 Care of UV quartz tube:
18
Especially in hard water
areas the quartz tube
sheathing the UVC lamp
may become covered in
limescale. This will reduce
the efficiency of the unit if
it is allowed to build up. To
clean, switch off the pump
and the power supply to
the UV, remove the
electrical housing, as
described in 7.1, and wipe
the quartz tube with a soft
cloth moistened with a
gentle cleaning agent such
as vinegar (See fig 18). You
should wear protective clothing when cleaning the
quartz tube such as safety glasses and gloves.
7.3 Cypricube foam replacement:
Inspect your foam annually. The frequency of foam
replacement will depend on your pond’s set up. We
recommend that foams are replaced during winter
and before you start feeding the fish again at the
start of the spring*. Changing the foam at other
times of the year may cause the pond chemistry to
alter and this may harm your fish.
