1.
Pressurized devices
• Do not exceed maximum operating pressure
indicatedonserialnumbertag.
• Makecertainlterisfullydepressurizedbefore
servicing.
2.
Breathing Air
• Air treated by this equipment may not
be suitable for breathing without further
purication.RefertoOSHAstandard1910.134

Drain Provisions
(1) InternalAutomaticDrains–DrainLine
The bottoms of internal automatic drains
are provided with 1/8" (inside threads) for
connectionofadrainlineifdesired.
(2) ExternalAutomaticDrains–
External automatic drains may be added as
follows:
(a) Models302through312–removeinternal
drain and install adaptor (available from
factory).Adaptoroutletconnectionis1/8"
(insidethreads).
Discharge is at system
pressure,anchordrainline.
(b) Models313through317–removeplugfrom
external drain adaptor tting at bottom
of bowl. The 1/2" (male threads) port is
available for external drain connection.
Filter may be drained with an electrical
demanddrain,ormechanically.
Do not attempt to remove

When to Replace Filter Element
NOTE:GradesS3,P3,U3,H3,C3-completeelementis
replaced;
1. GradesS3,P3,U3,H3
a. Operating pressure drop: As lter becomes
liquid loaded (wetted), pressure drop will
increase. Further pressure drop occurs as
elementloadswithsolidparticles.
FOR MAXIMUM FILTRATION EFFICIENCY, REPLACE
ELEMENT WHEN PRESSURE DROP REACHES 4.3PSID
(0.3BAR) (INDICATOR IN RED AREA) OR ANNUALLY,
WHICHEVEROCCURSFIRST.
NOTE: Pressure drop may temporarily increase when
ow is resumed after ow stoppage. Pressure drop
