This Vorton Ultra Violet
Clarifier is electrically operated
and designed to work with an
existing pond filtration system.
Typically this should consist of a
mechanical and biological filter, filter
pump and connecting hose. The unit
is only suitable for outside use.
ATTENTION - UV CAUTION
Caution - Exposure to Ultra Violet
(UV) radiation can be dangerous and
cause damage to eyes and skin.
Under no circumstances should any
attempt be made to gain access to
the lamp when the unit is switched
on. When switched on, the lamp can
be checked for operation by looking
for a bluish glow from the
translucent hosetails.
1. WARNING: SAFETY AND
ELECTRICAL CONNECTIONS
1.1 Always disconnect the electricity
supply before starting to handle,
maintain, repair or install any
equipment in the pond.
1.2 The clear tube inside the unit is
made from quartz glass and care
should be taken during installation
and maintenance. We recommend
the use of eye protection and
suitable gloves.
1.3 The Vorton UVC is weatherproof but
not submersible. Position the unit
horizontally near the pond but not
where it can fall into the water or
become waterlogged.
1.4 Important: This product is designed
to be permanently wired to the
mains supply. For connection to the
mains supply use only 3-core cable
(ref HO5 RN-F). This has a minimum
copper cross-section of 0.75mm
2
with
Polycloroprene-Rubber insulation.
The termination to the mains supply
should be:
a) Permanent.
b) Inside a dry weatherproof
enclosure.
c)
Through a double pole switched
fused spur with a minimum contact
gap of 3mm-(disconnector) to BS
3676.
d) Fitted with a 3 or 5 amp fuse.
1.5 Exposed cable runs should be
sensibly positioned and protected by
armoured conduit, especially if there
is a risk of contact with gardening
equipment such as forks and
lawnmowers, or children and
domestic animals.
1.6 A 10mA or 30mA Residual Current
Device (RCD) MUST be fitted to the
mains supply.
1.7 The installation must conform to the
national and local wiring regulations
which could include the use of
plastic or metal conduit to protect
the cable.
CONSULT A QUALIFIED
ELECTRICIAN OR LOCAL AUTHORITY
IF IN ANY DOUBT ABOUT WIRING TO
THE MAINS SUPPLY.
1.8 Protect from frost. In cold winter
weather (when fish are inactive and
algae growth ceases) the unit may
be switched off. It should then be
removed, drained of water and
stored in a dry, frost-protected area.

GENERAL GUIDANCE
2.1 Performance - We recommend that
for maximum performance this
product should be used with a
Hozelock Cyprio filter pump and
filter. The unit should be run 24
hours a day throughout the season.
Failure to do this may result in green
water and will invalidate the
Clearwater Guarantee.
2.2 Flow Rate - For best results the
entire contents of the pond should
pass through the Vorton UVC every
11/2 - 21/2 hours. We recommend
that your pump is sized to supply the
required flow rate against the full
hydraulic head (the vertical distance
between the pond water surface and
filter inlet, plus an allowance of 0.6-
0.9m, (2-3ft), for hose friction losses).
2.3 Pressure Rating - All Vorton UVC
models have a maximum pressure
rating of 8 psi (20ft; 6m; 0.6 bar).
The unit is therefore unsuitable for
filtration systems that produce high
levels of back pressure such as sand
filters.
2.4 Pond Treatments - Some medications/
treatments can degrade very quickly
by UVC radiation. Switch off the unit
during disease treatment.
2.5 Extra care should be taken with any
hose connections as leaks will result
in loss of water from the pond.
2.6 Spare Parts - Use only genuine
Hozelock Cyprio replacement parts.

INSTALLATION
3.1 The Hozelock Cyprio Vorton UVC can
be added to most filter systems
before or after filtration, the effect
is the same. The water must be
pumped through the unit - not
gravity fed. A typical installation is
shown in fig 1.
3.2 Location - the unit MUST be
installed horizontally and on a solid
surface. The lid of a filter may be
suitable if sturdy enough.
3.3 To mount the unit, first slide the
base from the main body. Using 4
suitable fixings, screw the base to
the mounting surface. (See fig 2).
Slide the main body back on to the
base.
For twin model (Vorton 27000), a
joining tube is supplied to connect
the units together (see fig 3). In this
case rotate the ends as shown and
connect together. Seat the unit into
position and, using the two base
mouldings as a template, mark the
hole positions.
3.4 Cut the two universal hose tails
(supplied) to suit the correct size of
hose. Fit the hose tails to the inlet
and outlet threaded connections
using the ‘O’ seals and threaded nuts
supplied (see Fig 4).
For Vorton 4500 use 25mm
(1inch)Hose.
For Vorton 14000 & 27000 use 40mm
(1 1/4 inch) Hose.
Push the inlet and outlet hose onto
the hose tails and secure with a
suitable hose clip. We recommend
the use of Hozelock Cyprio Hose and
Hose Clips (available separately).
Avoid kinks and sharp bends. Keep
hose lengths as short as possible to
minimise losses in flow.
Both ends of the unit can be rotated
to allow for easy hose connections.
Important - the outlet (A) should be
at the top of the unit, to ensure no
air is trapped inside. (See fig 2 & 3).
3.5 To fit the lamp refer to Section 5.1
3.6
Warning. This appliance must be
earthed, and it is essential that
connections are made using the
following code.
The BROWN lead must be connected to
the LIVE terminal marked ‘L’.
The BLUE lead must be connected to the
NEUTRAL terminal marked ‘N’
The GREEN/ YELLOW lead must be
connected to the earth terminal
marked
.
Brown - Live
Blue - Neutral
Green/Yellow -
Earth
3.7 Refer to Section 1, Safety and
Electrical Connections, for
termination to the mains supply.
We recommend that the pump and
UVC are connected to the same
supply so that they can be switched
off together.
3.8 Switch the pump and Vorton on and
check for leaks. Check the lamp is
operating by looking for a bluish
glow from the translucent hose tails.
DO NOT STARE DIRECTLY AT THE
UVC LAMP.
4 USER INSTRUCTIONS
4.1 Coupled to a Hozelock Cyprio pond
filter and filter pump, a Vorton UVC
should produce clear water within
two weeks. However, UV light can
delay filter maturation. When
installing a new biological filter,
allow 6 - 8 weeks before switching
on the UVC. During maturation
your pond may go green, but should
be clear within two weeks of
switching on your Vorton UVC.
Ammonia and nitrite levels may
initially rise due to decomposition of
algae trapped in the filter. Should
this occur, stop feeding until
ammonia and nitrite levels fall,
whereafter feeding may be
gradually increased to normal levels.
Run the filter and Vorton UVC 24
hours a day during the feeding
season. Should you need to switch
off the pump and filter, also switch
off the Vorton UVC. Continued
filtration in winter is recommended.
