Installation
1. Install unit vertically in air line -
• vertically (bowl down),
• with air flow in direction of arrow on body,
• upstream of regulators, lubricators, and cycling
valves,
• as close as possible to the air supply when
used as a main line filter,
• as close as possible to the device being
serviced when used as a final filter.
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 or bowl guard fully clockwise into
body before pressurizing. Lock symbols on
body and bowl guards must align.
5. Auto-drain units may be fitted with a short
drain pipe and connector, minimum 5 mm
bore, to the G1⁄8 bottom outlet.

Servicing
1. Open manual drain to expel accumulated
liquids. Keep liquids below baffle (53).
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 re
moved from the yoke by unscrewing the
clamp ring, which will jack the unit out
downwards.
3. Lift and turn the filter bow counterclockwise
and remove with bowl o-ring.
4. Disassemble in general accordance with
the item numbers on exploded view. Do not
4380-200 remove the drains or the service indicator
4380-040 unless replacement is necessary. Remove
4380-041 and replace only if they malfunction.
4338-01 Cleaning
4338-02 1. Partial cleaning of the filter element is possible
684-84 by washing the element in soapy water and
3000-97 blowing out thoroughly with compressed air.
5797-50 Replacement by a clean element is
recommended. Clean plastic bowl and lens
(45) with warm water only. Clean other parts
with warm water and soap.
2. Rinse and dry parts. Blow out internal
passages in body with clean, dry compressed
air.
3. Inspect parts. Replace those found to be
damaged. Replace plastic bowl with a metal
bowl if plastic bowl shows signs of cracking
or cloudiness.
Assembly
1. Lubricate o-rings with o-ring grease.
2. Assemble the unit as shown on the exploded
view.

Caution
Water vapor will pass through these units and
could condense into liquid form downstream as
air temperature drops. Install an air dryer if water
condensation could have a detrimental effect on
the application.
