Installation of Observatory Cover Seals
The seals included with the observatory equipment are designed to limit the inflow of rain and dust
into the observatory through the gaps at the edges of the observatory shutters, and at the edge of
shutter #1 with the observatory upper base ring. The seals are self-adhesive, but some of them re-
quire additional mounting adhesive for permanent attachment.
Three Seals are delivered in the following set:
- 20x15 mm EPDM seal mounted on the front edge of shutter #1
- 10x12 mm "D" seal mounted on the top edge of shutter #2
- Brush seal 20x7mm mounted on the back of the observatory, directly under the ring
- Brush seal 20x7 mm mounted on the inside, on the front of shutter #3
For the installation of brush seals, it is necessary to use fast-bonded adhesive applied at the installa-
tion site immediately before sticking them. All surfaces on which seals will be installed must be clean,
dry and skimmed with an appropriate means, such as technical acetone.
The installation of the seals is carried out with partially or completely open observatory shutters de-
pending on the location of their installation. Following photos show the course of their installation.
