DISASSEMBLY/MAINTENANCE
Always disconnect the power supply during maintenance/disassembly of the device.
The device must be cleaned at least twice a year. When there is a significant amount of algal growth and/
or lime build-up in the unit the quartz sleeve (M) must be cleaned.
The special lamp must be replaced after the number of hours of operation has elapsed. The inside of the
reactor can be cleaned with a soft brush.
1. Let the water flow out of the device.
2. Unscrew the nut (N) and remove the lamp (K) from the fitting (L). Remove the lamp from the quartz
sleeve, and replace the special lamp (K) if necessary. Caution is advised as these are very delicate
parts.
3. Carefully remove the quartz sleeve (M) (see figure 3). Never use force! CAUTION: Always wear
protective gloves and glasses.
4. Clean the quartz sleeve with an appropriate cleanser. Always use a soft cloth to clean the sleeve and
avoid scratches.
5. Carefully place the lamp back in the quartz sleeve, fit the O-ring (T) back onto the quartz sleeve and
connect the lamp (K) to the fitting (L). Screw the nut (N) back onto the housing.
If the housing or the electrical section must be replaced, the earthing must first be disconnected from
the housing. Please read the Installation and Disassembly section before installing a new housing or
electrical section. Make sure you save the various separate parts for the earth connection. These are not
supplied with a new housing or electrical section. If in doubt about the connection, consult a qualified
installer.
