Routine Maintenance
To ensure that the analyzer gives long and reliable service, regular cleaning and
changing of the filters is necessary. Failure to change the disposable coalescing filter
elements regularly may void warranty and service agreements.
Check the cleanliness of the disposable coalescing filter (Part No. FL5720A or OM
4700/11/10 (Pack of 10)) at the start of each day. If the filter shows signs of severe
contamination or a build up of deposits has occurred, remove and clean out the
housing using a lint-free cloth. Ensure that no deposits are pushed into the exit pipes
of the filter housing. Renew the disposable filter if heavily contaminated.
REPLACING COALESCING FILTER
To access Coalescing filter (FL5720A), firstly remove
clear catch pot from the water trap by unscrewing it
clockwise. Then unscrew black retaining column,
again clockwise to release filter.
Once replaced, screw filter back in and refit catch pot.
NOTE: Both filter and catch pot only need to be finger
tight. This will ease future filter replacement.
NOTE: Any dismantling of probe tip, sample hose or filters MUST be followed by a
manual leak test.
CAUTION: DO NOT run the analyzer without the filters in place!
At the beginning of each day, drain any water collected in the sample pipe and the
water trap.
