Installation
1. Install unit vertically in air line - upstream of
lubricators and cycling valves, with air flow in
direction of arrow on body, as close as
possible to the device being serviced.
2. Before assembling the basic unit into the yoke
the port seal o-rings should be lightly smeared
with o-ring grease.
3. Locate clamp ring under lugs on top of yoke,
offer basic unit into yoke with directional
arrows correctly aligned (an interference fit
prevents assembly if misaligned) before
engaging and fully tightening the clamp ring.
4. Turn bowl fully clockwise into body before
pressurizing.
5. Auto-drain units may be fitted with a short
drain pipe and connector, minimum 5 mm
bore, to the G1⁄8 bottom outlet.
6.Install a Norgren general purpose filter with a
5 μm element upstream of the oil removal filter
to obtain maximum element service life.
Operation
On exceptionally dirty lines it may be necessary
to clean the pre-filter element at 90 day intervals.
Do not exceed Maximum Flow rating or
excessive pressure drop will result or oil carry
over may occur. The top filter element acts as
absorbant pack to remove any small traces of oil
or hydro-carbon gases which might be carried
over from the lower bowl. These elements also
provide protection in the event of any failure of
the lower filter. Resistance to air flow will grad-
ually increase as the filter element collects solid
particles. The pressure differential across the
element should not be allowed to exceed
Servicing
Air Service equipment should be initially
maintained annually. Use, quality of air and
condition at examination may indicate
adjustment of the maintenance interval.
1. Open manual drain to expel accumulated
liquids. Keep liquids below element (46, 50).
2. To operate automatic drain manually, lift
operating pin in bottom outlet with a blunt rod.
3. Clean or replace filter element when dirty.
Disassembly
1. Shut off inlet pressure. Reduce pressure in
inlet and outlet lines to zero.
2. For ease of maintenance the unit can be
removed from the yoke by unscrewing the
clamp ring, which will jack the unit out
downwards.
3. To disassemble the lower filter section
unscrew the filter bowl (14, 21, 28, 37) and
remove with bowl o-ring.
4. Remove coalescing element (46, 50) by hand.
5. Remove pre-filter element (49, 54).
6. Unscrew top bowl and remove top element
(8).
7. Disassemble in general accordance with the
item numbers on exploded view. Do not
remove the drains unless replacement is
necessary. Remove and replace only if they
malfunction.

Cleaning
1. Partial cleaning of the pre-filter element (49,
54) is possible by washing the element in
soapy water and blowing out thoroughly
with compressed air. Replacement by a clean
element is recommended.The main
