Introduction
Congratulations on the purchase of your pondXpert filter. Once your filter is connected you
can look forward to many years of healthy pond water.
Your filter works by connecting it to a solids-handling filter via the stepped hosetail inlet via
pondhose. The water flow then passes through the filter’s chambers and finally back out into
the pond via the water outlet.
PondXpert filters are carefully inspected and tested to ensure both safety and operating
performance. However, failure to follow the instructions and warnings in the manual may
result in product damage and/or serious injury. Be sure to read and save this manual for
future reference.

Safety and Electrical Connections
EasyClean Sponges
Filter sponges simply lift
out by the handles the
squeeze out dirt by using
the grips as shown

This unit is designed for outdoor use only. It is weatherproof and should be situated safely
pondside. The filter should be sited where it cannot fall into the water or become
waterlogged.
NO PART OF THIS UNIT SHOULD EVER BE SUBMERGED IN WATER.
Direct exposure to UVC light can damage the eyes and skin. NEVER look directly at the
UV when switched on. The translucent inlet will illuminate showing that the UV is working.
Always disconnect all equipment in the pond before starting to handle, maintain, repair or
install any pond equipment.
The ultra violet clarifier housed within the pondXpert box filter is electrically operated so
great care must be taken during installation and operation. The following electrical and
safety guidelines must be carefully followed.
Each filter is supplied with a length of 3 core electrical cable which is permanently
connected to the ultra violet clarifier unit housed inside the filter.
The termination to the mains supply should be permanent, inside a dry weatherproof
enclosure, through a double pole switched fused spur with a minimum contact gap of 3mm –
(disconnected) to BS 3676 –and fitted with a 3 or 5 amp fuse.
Exposed cable runs should be sensibly positioned, and protected if necessary by armoured
conduit.
A 10mA or 30mA Residual Current Circuit Breaker (RCD) MUST be fitted to the mains
supply.
Permanent installations to the mains supply (hard wiring) must comply with the regulations
of the local electricity authority which may stipulate the use of metal or plastic conduit to
protect the cable.
If in any doubt about wiring to the mains supply contact a qualified electrician or your local
electricity authority.
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 drained of water, removed (if possible) from
its installation and stored in a dry, frost-protected area.
The supply cable cannot be replaced. If the cable is damaged, the unit must be discarded.
Directions for use
Installation
The wires in the mains electrical lead are coloured in accordance with the
following code:
BLUE –Neutral (marked with an “N” in most terminal connections)
BROWN –LIVE (marked with an “L” in most terminal connections)
GREEN/YELLOW –EARTH (marked “E” or in most terminal connections)
1st January 2005 revised Building Regulations for England and Wales
Installing this product in the garden is classified as ‘notifiable’. 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

Once installed and connected to a suitable pump the pond water will flow through the filter.
PondXpert box filters are pump-fed, external filters with an integral UVC unit, ideal for
being partially buried adjacent to your pond or being positioned above ground if desired.
The filter may also be concealed at the top of a waterfall.
Your filter is supplied with a translucent hosetail. This should be screwed into the threaded
filter inlet. Pond hose size 20-40mm (3/4” to 11/2”) can be attached to the inlet hosetail.
Your pump and filter outlet should be positioned at opposite ends of the pond to promote
maximum circulation.
Cut the inlet hose to the size appropriate to the size of hose you are using. Then connect the
hose from your pump to this inlet hosetail and secure with hose clips.
Maturation of the Filter
Your multi-chamber box filter comes complete with mechanical and biological filter media.
The filter foam acts as a mechanical barrier to pick up solids whilst the plastic bio-media
helps to develop ‘friendly’ bacteria. These friendly nitrifying bacteria help to convert
harmful fish waste and other organic waste (ie, ammonia, nitrite) into harmless nitrate. This
‘biological maturation’ process usually takes 6-8 weeks. It is recommended that you do not
switch on your UVC during this period.
Maintenance
As the filter does it’s job the foam filters will block up reducing water flow. If the pond is
very dirty then the foams may need cleaning every couple of days or so at first.
Cleaning procedure:
Switch off any electrical items feeding or inside the pond (including the filter itself).
Take the foam filters out of the unit and carefully wash away any solids using a bucket of
POND WATER. Once clean replace the foams back in position.
If your filter is ever taken away from the pond (ie-winter storage) then all of the filter media
(foams and biomedia) must be thoroughly cleaned before restarting. Your filter will then
need to undergo the ‘maturation’ procedure phase as described above.
Filtration Spares and consumables
The filter is supplied with everything you need to get started (including filter media, UV
bulb and quartz tube for the UV). Over time these parts may need replacing and can be
purchased from your retailer. The multi-chamber design of the unit means you are free to
test other media types (Japanese matting, Alfagrog etc) should you desire.
Bottom Drain Plug
Your pondXpert filter comes complete with an integral drain. To periodically drain the
sludge from the base of the filter simply unscrew the drain cap. This drain point can also be
used to backflush out debris if required.
Periods of operation
Maintain filtration 24 hrs a day through the fish feeding season (typically early March-
October when the water temperature is above 10 degrees C), but preferably all year round.
In the winter operating the pump and filter will maintain a background level of friendly
bacteria in the filter and help prevent the pond icing up in all but the severest weather
conditions.

Changing the UV Bulb
The UV bulb should be changed at the beginning of every new season. The lamp may look
like it is working but the levels of effective UV radiation decrease over time.
Disconnect the unit from the electricity supply.
Push open the top access chamber to the UV. Remove the UV Clarifier unit by gently
pulling the retaining clips. Unscrew the wired end-cap by rotating anti-clockwise.
Remove the UV bulb by gently pulling out of the electrical connection.
Insert a new UV bulb by gently pushing into the electrical connection.
Re-assemble the end cap by rotating clockwise.
Clip the UV unit back into the top housing and reposition the top lid in place.
Limited Warranty
This product is guaranteed for a period of 12 months from the date of purchase for material
or manufacturing defects. The guarantee covers the substitution of defective parts. However,
the guarantee is considered null and void in the case of improper use, improper handling or
negligence on the part of the buyer. The UV lamp is not guaranteed. If your pondXpert filter
fails please take it back to the retail outlet from where it was purchased. You will be
required to take your receipt/proof of purchase with you. This does not affect your statutory
rights.
