Installation
1. Install unit vertically in air line -
• vertically (bowl down),
• with air ow 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 lter,
• as close as possible to the device being serviced
when used as a nal lter.
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 t 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 tted 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 bafe (53).
2. To operate automatic drain manually, li
operating pin in bottom outlet with a blunt
rod.
3. Clean or replace lter 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. Li and turn the lter bow counterclockwise and
remove with bowl o-ring.
4. Disassemble in general accordance with the item
numbers on exploded view. Do not remove the drains
or the service indicator unless replacement is neces-
sary. Remove and replace only if they malfunction.
Cleaning
1. Partial cleaning of the lter element is possible
by washing the element in soapy water and blow-
ing out thoroughly with compressed air. Replace-
ment 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.
3. Torque Table
Torque in
Item N-m (Inch-Pounds)
55 (Filter guide) 2,0 ... 2,7 max (18 ... 25)
4. Assemble bafe (53), contact + 1/4 turn.
5. Turn bowl or bowl with guard fully clockwise
into body.
Caution
Water vapor will pass through these units and could
condense into liquid form downstream as air temper-
ature drops. Install an air dryer if water condensation
could have a detrimental effect on the application.
