Closing The Housing - Burkert 8681 Operating Instructions Manual

8.2.2.

Closing the housing

If necessary, clean the seal contour of the seal and of the hood and lightly lubricate it using a silicone
grease.
Caution:
Do not use any petroleum-based or synthetic lubricants (except for silicone grease)!
Procedure:
→
Put the plastic hood on the lower part such that the inner "lugs" are positioned over the locking grooves and
the external sealing lugs are positioned almost over each other. Press the hood completely over the seal of the
lower part.
→
Turn the hood by approx. 1.5 cm clockwise (meaning until the sealing lugs are positioned over each other).
→
If necessary, apply a lead seal to prevent opening without a tool.
The hood must be lead-sealed in the explosion-risk area to prevent the housing from being opened
without a tool!
