Only use the cleaning concentrate (see Chap. 4.5.) on the outside of the quartz tube.
In case of minor dirt, use a soft, clean and silicone-free cloth and a bit of methylated
spirit or acidic cleaning agent to remove scale and rust (ferrous deposits).
In case of severe dirt, use a more acidic (5%) cleaning agent (e.g. salt, formic acid or any
other acidic cleaning agent suitable to remove scale and rust) and rinse thoroughly with
water.
Observe the safety instruction of the relevant cleaning agents.
Use alcohol to remove any fingerprints from the quartz tube before installing the UV
module.
Dry the quartz tube with a clean and silicone-free cloth and then only touch the tube with a clean
cloth.
To clean the inside of the quartz tube a dry cloth will normally be sufficient.
Make sure the inside of the quartz tube is completely dry prior to installation.
Carefully guide the clean and dry quartz tube into the opening of the radiation chamber.
Carefully insert the clean and dry quartz tube into the radiation chamber and centre it on the spring-
loaded guide on the floor of the radiation chamber.
Carefully place the O-ring over the quartz tube.
Adjust the screw cap on the quartz tube to create a fit close with the protective cap. Tighten the
screw cap by hand (
, approx. 5 Nm) to create a tight connection with the O-ring.
(see Chap. 5.2.3 for figures and procedure)
Carefully guide the UVC lamp (Fig. 18) into the quartz tube.
Connect the UVC lamp with the connection plug (Fig. 19) in accordance with the instructions, slide
the protective cover (Fig. 20) towards the radiation chamber as far as it will go and tighten the cable
connection.
Connect the protective conductor (Fig. 21) to the earth connection of the radiation chamber in
accordance with the instructions.
