this approach prevents rapid clogging at start-up and subsequent need for filter ele-
ment replacement / cleaning.
•
Upon start-up, the filter chambers must be vented by opening (loosening) the upper
vent plug. Wait for fluid starting to leak and close (tighten) the vent plug again.
•
Normally, operation is started in “one-chamber mode” in order to allow for an immedi-
ate change-over to the reserve chamber in case of rapid clogging. This can happen
due to potentially increased dirt loads on the filter element during start of operation.
•
As an exception, the simultaneous use of both filter chambers is possible. This “dou-
blechamber operation mode” decreases high pressure drops observed with extremely
viscous liquids, which can happen e.g. during cold start at very low temperature. For
parallel operation of both chambers, turn the rotary slide valve to neutral position.
Immediately after start-up, change back to “one chamber operation mode”. Clean or
replace the filter element of the now bypassed chamber (see section 6.2: Cleaning of
filter elements) to have a clean filter element available as backup.
