SUP20S/T Installation of focusing lens

Note:

1. Please pay attention to the site environment when replacing. It is recommended to use sealant tape to protect the replacement.

2. The focusing convex surface faces downwards (that is, it faces the protective mirror after installation)

3. The sealing ring of the focusing lens is 15*21*2.7.

4. The default focusing lens specification is: (welding) D20*4.5 F150 (three-in-one cleaning) D20*3.5 F400.

(The F200/F400 lens is used in the illustration, so a washer is needed, which is not needed for the conventional model.)
