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.
3.5 To fit the lamp refer to Section 5.1
3.6 Warning. This appliance must be earthed.
3.7 Refer to Section 1, Safety and Electrical Connections,
for termination to the mains supply. The supply cable
of this Vorton UVC cannot be Replaced, if the cable is
damaged the UVC should be scrapped. 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 sight window.
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.
Maintenance
Always disconnect the electricity supply before starting
to handle, maintain, repair or install any equipment in the
pond. Read the relevant maintenance instructions before
opening the appliance.
5.1 How well your Vorton UVC performs is related to the
strength of the UV radiation produced. This will slowly
decline from the day your lamp(s) are fitted. The UVC
lamp has an effective life of 12 months. You need to
change the lamp when there is a significant reduction
in water clarity. Make sure this is due to an expired lamp
and not a badly maintained filter or a dirty/limescaled
quartz sleeve. Both can greatly reduce UV transmission
into the water.
5.2 Change the lamp at the start of the new season. Even
though the lamp still glows it may not be giving out any
useful UV radiation.
5.3 To fit a replacement lamp:
i)
Push the release button securing the electrical head
(See fig. 4 ). Turn the head anti-clockwise, and pull out.
The head should then pull gently away from the main
body (See fig. 5).
ii) Remove the quartz glass tube by removing or loosening
the screw on the quartz tube locking ring (See fig. 6),
rotating the plastic locking ring anticlockwise and
pulling away from the body, (see fig. 7).
iii With the lamp holder now accessible, remove the old
lamp and push the new lamp into position. The two
black spacers that fit onto the lamp, must be fitted in
order to prevent possible damage to the lamp/quartz
tube (See fig. 8/9)
iv) Re-assemble the quartz tube into position ensuring the
O-ring is positioned over the end of the quartz tube
(See fig. 10) before the locking ring is retightened and
screw refitted/retightened. Do not attempt to operate
the UV lamp when it is removed from the UV Clarifier
enclosure.
v) Re-assemble the head to the body. Using the reverse
procedure stated in (i) above (see fig. 4 &5). There
should be an audible click from the release button
mechanism when the electrical head and UVC housing
are secured together correctly.
5.4 Especially in hard water areas, the quartz tube may
become covered in limescale, which will reduce
efficiency. To gain access to the tube and lamp refer to
section 5.1. Clean the tube with a soft cloth and a gentle
de-scaler, rinse in water before refitting.
DO NOT SUBMERSE THE UNIT IN WATER.
5.5 Wash out the inside of the main body to remove dirt and
debris.
5.6 Always check the system thoroughly for leaks when
restarting.
Winter Storage
6.1 When not in use, the unit should be removed, thoroughly
washed, dried and stored in a dry frost protected area.
