Housing Maintenance
a)
Always be vigilant of pressures, temperatures and redisual process fluid when performing maintenance
on the filter housing.
b)
Always isolate the filter housing from the process, depressurize and drain process fluids before opening.
c)
Frequently inspect the condition of pressurised parts, accessories and connections for corrosion,
abrasions, deformation due to blows, breakage or any other abnormal condition which could lead to
the onset of a hazardous situation.
d)
Replace worn parts with those designed for the filter housing. Check the condition of filter housing
seals each time the cartidges are replaced; replace if damaged. It is recommended that the seals are
replaced annually except for PTFE and/or FEP seals that should be replaced each time the filter housing
is opened.
