8.2 Dismantling and Reassembling
Warning
In case the screws of the cover must been replaced, a
SS AISI 316 Class A4 Grade 70, must be used with
minimum yield strength of 450 N/mm

In case a dismantling and subsequent reassembling of the explosion-proof
enclosure is required, be careful to maintain all parts in their original condition.
So the following procedure must be followed:
Do not damage the explosion-proof mating surfaces on the housing and on
the electrical enclosure cover.
Reinstall all the screws that go with the dismantled parts and block after
spreading them with a film of molybdenum-based grease. This will keep
screws from sticking and make maintenance future operations easier.
In case the screws need to be changed it is mandatory to assure that the
new screws are of the same dimension and same material as the original
ones as stated in this Manual, or of a better quality.
Replace the weatherproof seals that may have been removed i.e: O-Rings
for the cover.
In particular, be sure the joint surfaces of all enclosures are spread with a
film of Aeroshell grease.
