Installation
If you have a severe algae problem you should effect a partial water
change before starting the installation. Algae Masters can be added
to any existing filtration system. For best results the unit should
be fitted in line, after the pump, with water being forced through it.
Use the largest size of pipe possible. If hosetails are to be used,
it is very important that they are trimmed to the largest possible size
that will fit inside the flexible pipe (before glueing in place). This
will ensure that the maximum flow rate can be obtained for the size
of pipe.
Algae Masters have
been designed to run for twenty four hours a day, twelve months of the
year. They should be installed in a well ventilated position but protected
from frost and at no time allowed to freeze.
If you are unable
to position the unit in a location where it will not freeze, you should
make allowances during the installation to ensure you can easily remove
it for storage during the colder times of the year.
Maintenance
Although maintenance is minimal all UV lamps need replacing at six monthly
intervals. The lamp may be illuminated and appear to be working but
the radiation dosage diminishes with age and is ineffective after six
months. Dispose of used lamps sensibly. Even exhausted lamps should
NEVER be looked at directly when illuminated.
As the unit is dependant
upon water passing through it, it is important to ensure that any pump
strainers, pre-filters or delivery pipes are not blocked or are causing
the flow to be restricted.
To
change the lamp
Isolate unit from mains power, turn off pump, remove shower-proof ends
and lamp holder, carefully slide out lamp, undo circular nut at each
end of unit, remove “O” rings, one from each end, carefully
slide out quartz sleeve. To clean use rag dampened with pond water,
wipe dry with a cloth and reinstall. Use no chemical cleaners harmful
to fish. To reinstate slide silica quartz sleeve back into position
carefully, reposition “O” rings at either end over quartz,
centralise tube with an even amount protruding at either end, replace
nuts (hand tighten only), turn on pump and test for leaks, if on inspection
no leaks are apparent replace lamp as above and reconnect.
WARNING
Do not look at the lamp when on (even old or exhausted lamps)
Do not submerge unit
Do not run without a constant water flow (the unit is watercooled)
Do not allow water to freeze within the unit
Do not open while switched on
Do not use with broken or chipped quartz sleeve
Algae Masters
are guaranteed for 12 months excluding lamps and breakages
