INSTALLATION (continued)
1. Be sure to read all "Warnings" and "Cau-
tions" in this manual and on the unit before
installation or using this equipment.
2. Install filter as close as possible to point
where air is being used. Install main air
shut-off valve and standard pipe union
(supplied by user) upstream of filter to
allow maintenance to unit.
3. Install unit with air flow through filter
in direction of arrow on top of unit.
4. Minimum 1/2" piping is recommended.
Avoid using fittings, couplings, etc.
that restrict air flow.
5. Mount filter in a vertical position.
6. Do not install filter in an application
where the pressure drop will exceed
20 psi. For example, a quick opening
valve located upstream from the filter
could cause a momentary pressure
drop in excess of 20 psi.
7. Maximum inlet pressure and operating
temperature is: 150 PSIG (10.3 bar) and
150° F (65.6° C).
8. A 6' length of vinyl tubing is shipped loose
with the unit. Slide over automatic drain
which protrudes from bottom of bowl. Place
other end of vinyl tubing into appropriate
receptable (i.e. below booth grating, can,
etc.). Prevent vinyl tubing from becoming
kinked which would prevent free movement
of liquids discharged from the automatic
drain.
9. An optional manual drain (HAF-11) can be
installed in place of the automatic drain.
OPERATION
After the unit is installed and ready to use;
1. Attach air hose(s) to outlet ball valve(s),
selecting regulated and/or non-regulated
according to the application (not supplied).
2. Open main shut-off valve upstream of filter.
3. Open ball valve(s) (not supplied) to supply
air to spray gun or tool being used.
4. After use, shut off ball valve(s) and bleed
off residual air in hose(s).
Note
The filter change indicator only
operates when air is flowing. It
will always be green when there
is no flow.
MAINTENANCE
Certain solvents, paints and
chemicals may attack plastic
bowl and can cause bowl failure.
Do not use near these materials.
When bowl becomes dirty, wipe
only with a clean, dry cloth. Im-
mediately replace any crazed,
cracked, damaged or deteriorated
plastic bowl with a new plastic
bowl. Reinstall metal bowl guard.
Risk of injury. Components under
pressure. Relieve air pressure
before performing maintenance.
1. Before performing maintenance on unit,
close main shut-off valve located upstream
of filter. Bleed off residual air in unit.
2. To open filter, press button located on
clamp ring and rotate ring either clockwise
or counterclockwise while pulling down on
ring. The metal bowl guard and plastic bowl
can then be removed from the filter head.
3. Remove the filter element by loosen
-
ing counterclockwise. Clean or replace
the filter element. Frequency of element
replacement will depend upon air quality,
air usage, and condition of the air piping.
It is recommended to check the element
change indicator daily, and replace when
indicator turns red.
4. Inspect o-ring for damage. Replace if
necessary.
5. Inspect plastic bowl for signs of damage
such as cracks, crazing or deterioration.
Replace if necessary. See "Caution" in
column 2.
Risk of injury. Do not place unit
in service without metal bowl
guard installed.
6. Before placing unit back into service, make
sure plastic bowl and metal bowl guard are
properly installed and securely locked in
place.
7. Confirm automatic drain operates properly
after unit is in operation. Refer to Service
Bulletin SB-6-149 which provides automatic
drain service information. Replace if neces
-
sary.
