Filter element replacement
The OffLine Separator OLS is supplied with filter element(s) at delivery. At replacement of
Filter element, the electrical power supply must be disconnected, the housing must be de-
pressurized and completely drained.
Replacement procedure is as follows:
•
Disconnect the electrical power supply, if the Separator has a pump-motor group
installed,
•
Close shut off valves, if installed.
•
De-pressurize the housing by carefully opening the bleed plug on the top of the
housing.
•
Open the sampling point valve and the drain valve and collect the fluid (follow
regulations for personal protection and environmental protection).
•
When the housing is completely drained, open the housing clamp and remove the
upper housing.
•
Turn the locking cap 90° in a counterclockwise direction for one element package.
For each additional element package turn an additional 90°.
•
Remove the contaminated element(s) and clean the filter (upper) housing.
•
Remove the sealing flange for inspection of the separation (lower) housing. Remove
the spacers and outlet demister and clean them if required.
•
Inspect the O-ring(s) for damage, and renew if necessary.
•
Install drip catcher filter, oil guide filter, spacers, sealing flange and new filter
element(s) in reverse order to the removal sequence.
•
Grease and install O-ring. Re-install the upper housing and clamp. Tighten the
housing clamp until the two housing halves seat against each other.
•
Re-install the bleed plug, but leave it open.
•
Close the sampling point valve and drain valve, open the shutoff valves if installed,
connect the electrical power supply and start the pump.
•
Fill the housing completely, keeping the bleed port open until fluid escapes from it.
WARNING:
Do not unscrew the bleed port plug completely. The plug has vent grooves.
•
Dispose the contaminated filter element(s) in accordance with local waste disposal
regulations.
