Check the filter to make sure that the threaded nipple did not
unscrew with the filter. If it is in the filter, remove it carefully
to avoid thread damage, clean the threads and then coat the
threads that go into manifold block with a small amount of
Loctite blue and install it into the manifold block. Use caution
when removing the filter so as to avoid catching the
scavenge screen orifice on the bottom of the scavenge tube
on the lip of the coalescing filter. This scavenge screen
orifice is attached to the scavenge tube by a "push to
connect" fitting, if the fitting has come off of the tube re-insert
the tube into the fitting ensuring that the tube is fully
engaged.
2.11.1 Check the gasket-sealing surface of the manifold block for
contamination, old gasket material or damage.
Make sure the new filter is a VMAC filter, part # 3600079.
This is a high pressure filter. Use of other filters not rated to
the required pressure may cause the filter to rupture.
2.11.2 Apply a thin coating of compressor oil to the coalescing filter
sealing gasket and coat the end of the threaded nipple, as
there is also an O-ring inside the coalescing filter.
2.11.3 Spin the filter onto the threaded nipple until the gasket
contacts the sealing surface of the manifold block.
2.11.4 Tighten the filter an additional 3/4 to 1 turn to seat the sealing
gasket.
Never over-tighten the filter, as this may damage the seal or
filter.
2.11.5 Check the oil level following the oil level checking procedure
in Section 2.4.
