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.
From
1st January 2005
installing this
product in the garden is classed as
'notifiable' in the revised Building
Regulations for England and Wales.
The Regulations now require you to
tell your local authority building
control department that you intend to
install this product before installation.
Your local authority will let you know
how you can get your installation
approved.
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 Permanent installations to the mains
supply (hard wiring), must conform to
the National and Local wiring
regulations. If in any doubt about wiring
to the mains supply, consult a qualified
electrician or local electricity authority.
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. (See section 8).

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 models (Vorton 18000 and
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 2200; 4500 use 25mm
(1inch)Hose.
For Vorton 9000; 14000; 18000, 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. Speed up
maturation by adding a maturing agent
such as Hozelock Cyprio filter start.
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. (Check these levels
with Hozelock Cyprio test kits). 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. UVC treatment in winter
is optional, but if there is any risk of
freezing, the unit should be switched off,
drained and removed. This will prevent
damage to the product.
5 MAINTENANCE
Always disconnect the electricity supply
before starting to handle, maintain,
repair or install any equipment in the
pond.
5.1 To fit the lamp:
i) Remove the screw securing the
electrical head ( See fig 5 ). Turn the head
anti-clockwise, pull out and then turn
clockwise. The head should then pull
gently away from the main body.
ii) Remove the quartz glass tube in a
similar way by removing the retaining
screw, rotating the plastic moulding
anticlockwise and pulling away from the
body, (see Fig 6 ).
iii) With the lamp holder now accessible,
