the reach of children. Place the ballast in a area protected against the sun and rain.
Exclusively use grounded sockets with closing cover. Prevent the plug and the
receptacle form getting moist. Please provide a good quality grounded connection
to the electric mains and use an earth leakage circuit breaker rated 30 mA. If the
flow of the water stagnates, for example as a result of blockage of a defective pump,
the UV-C lamp should be switched off at once. If the apparatus or its flex should
become damaged, the power supply should be switched off immediately too.
MAINTENANCE
In order to maintain optimum action of this UV-C filter, the feed and discharge
connections and the quartz glass should be cleaned at least 3 times a year. To
achieve this, you should proceed as follows: switch off the power supply of the UV-C
and the pump installation. Now carefully remove the quartz tube and clean it with
lukewarm suds. Lime deposit, if any, should be removed with vinegar. The effective
life of the PL UV-C lamp is about 7,500 burning hours. If used continuously, the UV-C
lamp will consequently last for one pond season. It is recommendable to install a
new UV-C lamp in March. Place the spacer round the top of the new lamp for extra
stability. Only after a week or two, the output of the PL UV-C lamp will be optimum.
This is a normal process for this type of lamp.
