LAMP LIFE
The UV lamp fitted in this unit has a usable of life of 8000 hours (one year). At 8000 hours the lamp will still be
glowing brightly but the emission ofgermicidal UVC will have deteriorated to approximately 85% efficiency.
Forthe majority of home aquarium applications the lamp should be changed once a year(8000 hours).
Formore critical applications the lamp should be changed at 4000 hours (6 months).
ROUTINE MAINTENANCE
The UV lamp should be changed at intervals of either4000 hours or 8000 hours dependent on application.At each
lamp change the quartz sleeve should be removed and cleaned.
Water displacement gasket
A soft black circularrubber gasket is fitted to the right hand side ofthe white plastic body to protect the lamp holder
assembly from any accidental water spillage orsplashing. Each time the cover is removed from the base this gasket
must be correctly located on re-assembly.
When replacing the cover, and before screwing it to the base,make sure that the gasket is fitted onto the right hand
end of the white plastic body and located between the white plastic body and the white plastic compression fitting.
It will be held (loosely) in place by this compression fitting.When correctly fitted the gasket must lean towards the
right,away from the outlet port. When the coveris replaced on the unit this gasket will be visible through the cover
and should be tilting away from the outlet port and towards the lamp end and lamp holder.
When correctly fitted this gasket will protect the lamp end assembly from any possible water splash.
