ASSEMBLY PROCESS
Slide the quartz sleeve into the unit. Ensure that you locate the two “O” rings
carefully on the ends of the quartz sleeve. Failure to do so will result in leaks
when the water is turned on. If you are carrying out the annual lamp change,
use new “O” rings. Firmly hand tighten the compression fittings. Replace the
lamp or fit a new one. Relocate the white electrical end caps onto the pins of
the lamp and slide the rubber endcaps over the compression fittings. Reconnect
and turn on the water supply, carefully checking for any leaks before switching
on the electricity supply.
TROUBLE SHOOTING
Some Common Questions:
How can I tell if the unit is working?
The translucent hosetails will glow when the unit is operating correctly. In
strong sunlight this may not be apparent, but at night and at low light levels the
glow is easily detectable.
How long after I install the unit will my pond become clear?
There are many factors which control this, including the levels of nutrients
available to the algae, the water temperature and the level of sunlight.
Assuming that the correct size unit has been properly installed most ponds
should clear within 3-14 days. However, please allow a full six week period for
the unit to take effect.
The lamp is not working. Even at night the hosetails are not glowing.
What is wrong?
First check the power supply and the fuse. Check that the white electrical end
caps are correctly located on the lamp pins. If it still doesn’t work, remove the
lamp (as detailed on the previous page). Check that the lamp and the quartz
sleeve are not broken. Remember to switch off the electricity and water
supplies before carrying out any maintenance on the unit.
The unit worked well when I first installed it but recently my pond has
gradually gone green again – what is wrong?
This usually indicates that the quartz sleeve has become dirty and requires
cleaning (read maintenance instructions). Also make sure you have the right
model for your pond size by checking the table on the front inside cover of this
leaflet.
Does a Pro Clear Advantage unit put anything into the water, and will it
harm anything living in the pond like frogs, newts, plants or fish?
Ultraviolet lamps leave no residues, and only affect the water pumped through
the unit. Unlike many chemical treatments, your Pro Clear Advantage unit will
not harm the plants and animals living in the water.
How long can I leave the unit running?
Pro Clear Advantage units should be run 24 hours a day, every day, from mid
March to early October, depending on the weather conditions. If the unit is
frost protected it may be left running throughout the winter. Otherwise, the unit
should be removed, drained and stored safely for the winter.
Can I use my Pro Clear Advantage unit if I am using any treatments for my
fish?
From our own experience of using a wide range of treatments and medications,
we have found no harmful effect from running Pro Clear Advantage units at the
same time as treating a pond, although some medications may be broken down
a little quicker than normal. Always check the manufacturer’s instructions
before using any water treatment.
Can I bury the unit underground?
Do not bury the unit. It could become waterlogged at a later date, which would
be dangerous.

General Note: Large fish such as Koi can cause murky water by
stirring up the bottom of the pond. This murky water should not
be confused with suspended algae.
