1. Unscrew the nut (N) from the housing (U). Remove the UV-C lamp (K) from the supplied tube (see
packaging) and carefully slide the lamp into the quartz sleeve (M). Place the lamp (K) with the
contact pins in the lamp fitting (L) and then tighten the nut (N) on the housing (U).
2. Fit the supplied pipe clamps (O). Then insert the unit into the pipe clamps. Tighten the three-piece coupling (I) firmly,
while ensuring the correct position of the sealing rings (P), both at the connections and the quartz sleeve (see figure 2).
3. Mount the unit in the circuit by means of the three-piece coupling (I) and the glue coupling for the flow switch (V
*For amalgam only). The glue connections of the three-piece coupling are Ø63 mm or 2”. If the pipes are smaller
than Ø63 mm or 2”, use the Ø63 x 50 mm (T) or 2” x 1.5” x 1” adapter. This can be glued in the three-piece coupling
(I) and in the glue coupling for the flow switch (V *For amalgam only). The inside of the adapter (T) has internal
screw threads at one end, making it possible to fit a hose tail adapter (not included) with sealing ring.
4. Insert the plug of the UV-C device into an earthed wall socket that is protected by a residual current device.
5. Look through the transparent parts of the device to make sure the lamp is lit.
6. The device is shut off when power is disconnected from the device.
Instructions for use led hour meter (figure 4)
When the UV-C device is switched on, the program performs a self-diagnostic test. The LED
flashes red quickly for about one second. Then the LED lights green, flashes green or lights red.
This depends on the number of hours that the system has already been in operation.
When the UV-C lamp is switched on for the first time, or after the ‘reset’ function is used, the value will be 9.000.
The number of hours is based on the lamp in your device. Each UV-C lamp has a maximum number of operating
hours, during which the lamp provides optimum disinfection. After this number of hours the lamp must be
replaced. When the system is switched off, or after a power failure, the system will remember the remaining
number of hours. When it is switched on again the system will continue counting from where it left off.
Hour meter status
• Lit green: the UV-C lamp is operating within its normal service life.
• Flashing green: the UV-C lamp will need to be replaced after 500 more hours.
• Lit red: the UV-C lamp should be replaced as soon as possible.
Resetting the hour meter
After the lamp is replaced, the system can begin counting again. First you must perform a ‘reset’.
A reset changes the hour meter reading back to the programmed number of hours.
• Hold the button.
• The LED will flash quickly and then light green. This takes a total of about 6 seconds.
• As soon as the hour meter is lit green you can release the button.
• The hour meter will begin counting a new cycle as described under ‘hour meter status’.
