IMPORTANT
The outlet hose should be installed over as short a distance as possible with no kinks or bends.
We recommend that Blagdon hose is used.
CONNECTING INLET HOSES
The recommended hose size for
your Minipond UVC is stated in
the UVC performance and
specification chart.
Always secure hose with a jubilee clip.
Warming the hose in a bucket of
boiling water can aid fitting.
Always ensure that the smaller
diameter hosetail is cut off and
removed to prevent reduced UVC performance.
Use the shortest possible hose lengths to minimise flow restrictions.
Avoid folds and kinks in the hose, which will reduce flow and UVC performance.

INSTALLATION
CONNECTING TO YOUR PUMP
The pump supplying the Minipond UVC must not have a pumping head exceeding 4m - 0.4 Bar.
The maximum flow rate recommended is stated in the UVC performance and specification chart.
This flow should not be exceeded.
The ideal flow rate for your pond is to pump the volume of the pond water through the UVC every 2-4
hours. To calculate your pond volume: average length (m) x average width (m) x average depth (m) x
1000 = Litres Pond Volume.
To calculate your pump’s flow rate, fill a container from the outlet hose of the UVC at the pond side.
Time how long this takes in seconds e.g. a 10 ltr bucket takes 12 seconds to fill. Divide 3600 (the number of
seconds in an hour) by the time it takes to fill the bucket e.g. 12 seconds. Then multiply by the volume of
the container. e.g. 10 ltr. Therefore - 3600 ÷ 12 = 300 seconds 300 x 10 ltr = 3000 ltrs per hour flow rate.
To increase flow you may need to get a larger pump. If flow is too high use an inline valve to reduce it.
The purpose of the pump is to transfer green water from the pond to the Minipond UVC.
Placing the pump at the opposite end of the pond to the UVC will give the best results.
We recommend Blagdon Amphibious A Pond Pumps, Minipond 2000, Hydratech Multi or Hydratech
Torrent Pond Pumps.
UVC LAMPS & QUARTZ SLEEVE MAINTENANCE
The UVC lamp must be replaced every six months / once a season. It is recommended that the lamp is
replaced and reconnected in the spring.
The Quartz sleeve can become coated in lime scale build up in hard water areas. This should be
carefully removed from the quartz sleeve with a soft cloth.
Blagdon Pond Pump Cleaner should be used in stubborn cases.
Remove the quartz sleeve from the unit and soak for 3 hours in Pump Cleaner, ensuring that all O-rings
are checked and replaced, if necessary.
A wet test must be carried out after maintenance to ensure there are no leaks before the UVC is
reconnected.
WET TESTING THE UVC
IMPORTANT:
A wet test of the UVC under operating conditions must be carried out before
the UVC or electrical supply is installed.
Connect the UVC to the pump following all installation instructions.
After running for 24 hours check for leaks.
CONVENIENT INSTALLATION
Minipond UVC can be used in conjunction with any in-pool or external filter for effective control of
green water.
