Risk of personal injury.
Risk of property damage.
Except as otherwise specified by the manufacturer, this
product is specifically designed for compressed air service
and use with any other fluid (liquid or gas) is a misap-
plication. For example, use with or injection of certain
hazardous gases in the system (such as oxygen or liquid
petroleum gas) could be harmful to the unit or result in a
combustible condition that may cause fire or explosion.
Manufacturer’s warranties are void in the event of misap-
plication and manufacturer assumes no responsibility for
any resulting loss.

INSTALLATION
Risk of injury. Release all air pressure from system
before servicing system. Do not place unit in ser-
vice without metal bowl guard installed. Plastic bowl
units are sold only with metal bowl guards. To minimize the
danger of flying fragments in the event of plastic bowl failure,
guard must not be removed. If the unit is in service without
the metal bowl guard installed, manufacturer's warranties
are void and the manufacturer assumes no responsibility
for a resulting loss. If unit has been in service and does not
have a metal bowl guard, order one and install before plac-
ing back in service.
Certain solvents, paints and chemicals may attack plastic bowl
and can cause bowl failure. Do not use near these materials.
IMPORTANT:
Read and follow all instructions and SAFETY PRECAUTIONS before
using this equipment. Retain for future reference.
1. Be sure to read all "WARNINGS" and "CAUTIONS" 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 main-
tenance 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. A 1/2" street elbow will be needed to allow vertical pipe instal-
lation. 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. Install "T" handle into regulator (Model HFRL-508).
8. Maximum inlet pressure and operating temperature is:
150 PSIG (10.3 bar) and 150° F (65.6° C).
9. 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 receptacle (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.
10. An optional manual drain (HAF-11) is supplied loose in the
carton (see item 10, Fig. 2). If desired, this can be installed
in place of the automatic drain.
OPERATION
After unit is installed and ready to use:
1. Attach air hose(s) to outlet ball valve(s), selecting regulated and/
or non-regulation according to the application.
2. Open main shut-off valve upstream of filter.
3. Main line air pressure is monitored by the top air gauge.
4. Adjust regulator to desired setting by turning "T" handle
in or out.
5. Open ball valve(s) to supply air to spray gun or tool being
used. With air flowing, readjust air pressure at regulator
if necessary.
6. After use, shut off ball valve(s) and bleed off residual air in hose(s).
MAINTENANCE
Certain solvents, paints and chemicals may attack plastic
bowl and can cause bowl failure. Do not use near these ma-
terials. When bowl becomes dirty, wipe only with a clean, dry
cloth. Immediately replace any crazed, cracked, damaged or
deteriorated plastic bowl with a new plastic bowl. Reinstall
metal bowl guard.
1. If bowl is equipped with manual drain, drain bowl at least once
per shift. Units with automatic drain will drain automatically.
2. Before performing maintenance on unit, close main
shut-off valve located upstream of filter. Bleed off residual air
in unit.
3. To open filter, press button located on clamp ring and
rotate ring either clockwise or counterclockwise. The metal bowl
guard and plastic bowl can then be removed from the filter head.
IMPORTANT! DO NOT DESTROY
