E.8.2 Disassembly and Re-assembly
 CAUTION
Using a fastener other than the approved type may result in damage to the actuator or
valve. Refer to Table 7.
 CAUTION
Failure to use proper torque values can result in damage to the actuator and/or valve.
If disassembly and subsequent re-assembly of the explosion-proof enclosure is required,
take the necessary care to maintain all parts in their original condition.
To achieve this, the following steps must be taken:
• Do not damage the explosion-proof mating surfaces on the housing or on the
electrical enclosure cover.
• Reinstall all the screws that came with the dismantled parts and coat them with a
lm of molybdenum-based grease. This will prevent the screws from sticking and
make future maintenance operations easier.
• If the screws need to be changed, the new screws must be of equal dimensions
and at least equal material quality to the screws originally supplied with the unit.
• Replace the weather-proof seals that may have been removed, i.e. O-Rings for
the cover.
• In particular, be sure to spread a lm of Aeroshell grease over the joint surfaces of
all enclosures.
