6. Pull out the UVC bulb and replace it. Note: The UVC bulb can be inserted
in the setting in any position. Note: The rubber band on the original UVC
bulb is for protection during transport and does not need to be replaced.
Note: Because of the built-in safety switch the UVC light only comes on
after the UVC is completely assembled.
Attention! Only use bulbs whose designation and wattage agree with
the specifications on the nameplate.
7. Remove the O-ring from the quartz glass, clean and check for damage.
8. Clean the quartz glass sleeve from the outside with a damp cloth. Check
the quartz glass sleeve for damage before putting it back.
9. Replace the O-ring on the quartz glass sleeve and insert the quartz glass
sleeve in the device head until the stop. The O-ring must be pressed into
the gap between the device head and the quartz glass. The O-ring is later
forced into the correct position by the clamp screw.
10. Screw the clamp screw on clockwise until the stop (see fig.). Note: If the
clamp screw is not screwed on until the stop, then the device head
cannot be mounted with the device.
11. Push cleaning rotor onto the quartz glass sleeve (see illustration).
12. Check the O-ring on the device head for damage and correct seat. The O-
ring must sit in front of the recess on the device head (see fig.).
13. Push the device head carefully into the housing. The cleaning rotor and
the quartz glass sleeve will be pushed into the rear receptacle inside the
housing in this process.
14. The interior marking on the device head must agree with the marking on
the housing (see fig.). Push the device head carefully into the housing
until the stop. Note: If the device head cannot be completely pushed on,
then check whether the clamp screw is screwed on until the stop.
15. Turn the device head in the opposite direction of the arrow using light
pressure until the stop (markings on the device head and housing point to
each other). The safety engaging lever must click to place.
16. First place the pump in service again, then plug the Bitron's power plug
into the power outlet (see chapter "Placing in service").
9.2 Replace cleaning rotor
To check the wear on the foot of the cleaning rotor there are several wear
marking ribs attached to the foot of the cleaning rotor (see Fig. 2).
If the running area is rubbed off up to the wear marking ribs, then the cleaning
rotor must be replaced.
1. Unplug the Bitron's power plug.
2. Switch off the pump and safeguard it from being turned on again
unintentionally.
3. Press the safety engaging lever, turn the Bitron device head in the direction
of the arrow until the stop, and pull it out carefully with the cleaning rotor.
4. Pull cleaning rotor off of the quartz glass sleeve and replace it.
5. Check the O-ring on the device head for damage and correct seat. The O-
ring must sit in front of the recess on the device head (see fig.).
6. Push the device head carefully into the housing. The cleaning rotor and
the quartz glass sleeve will be pushed into the rear receptacle inside the
housing in this process.
