•
Use only genuine ARO replacement parts to assure com-
patible pressure rating and performance.
•
Read carefully all warnings and safety precautions and
heed the following before operating, to avoid personal in-
jury and / or property damage.
•
Be certain anyone operating this equipment has been
trained to use it safely.
WARNING
COMPONENT RUPTURE. DO NOT EXCEED
MAXIMUM RATED OPERATING PRESSURE OF 200 p.s.i.
(13.8 bar). To avoid possible damage or personal injury, DO
NOT expose the unit to excessive pressure beyond the in-
tended working range.
WARNING
TEMPERATURE LIMITS. DO NOT EXCEED
MAXIMUM TEMPERATURE LIMITS OF 180_ F (82_ C). Ex-
cessive temperature can affect non-metallic parts which may
weaken them and cause failure.
WARNING
USE WITH INDUSTRIAL COMPRESSED AIR
SYSTEMS ONLY. DO NOT USE WITH BOTTLED GAS
PRODUCTS OR FLUIDS. MISAPPLICATIONS CAN RE-
INSTALLATION
•
Install regulators with the air flow as indicated by the arrow on
the top of the unit.
•
Install regulators as close as possible to the air operated
equipment for best performance.
•
Locate the regulator upstream from the lubricator.
•
Mount with the knob up or down on regulator.
•
If the air line contains water, sludge or foreign materials, a filter
should be installed on the upstream side to protect the regula-
tor.
•
See gauge port "CAUTION".
•
A tamper resistant feature is available to lock in specific air re-
quirements.
•
After a regulator has been installed in the air line, the adjust-
ment knob should be turned counterclockwise until compres-
sion is released from the pressure control spring. This
prevents over pressurizing the air operated equipment when
the air supply is turned on.

OPERATING AND SAFETY PRECAUTIONS
SULT IN COMPONENT FAILURE.
WARNING
DISASSEMBLY HAZARD. DO NOT DISAS-
SEMBLE THIS UNIT WHEN IT IS UNDER PRESSURE.
SHUT OFF AND RELIEVE AIR SUPPLY BEFORE AT-
TEMPTING SERVICE OR DISASSEMBLY PROCEDURES.
Isolate the unit by closing the line valve or disconnect the sup-
ply line or hose.
CAUTION
THE REGULATOR GAUGE PORT SHOULD
NOT BE USED AS AN AUXILIARY PRESSURE OUTLET
PORT. The gauge port is intended to be used only for pressure
monitoring, sensing or remote pilot. The feedback may affect
the set pressure.
NOTICE
Secondary pressure adjustment ranges are not
minimum or maximum secondary pressure limits. Regulators
can be adjusted to zero p.s.i.g. secondary pressure and, gen-
erally, to pressures in excess of those specified. The use of
these regulators to control pressure outside of the specified
range is not recommended.
OPERATION
•
Pull knob to adjust air pressure.
•
Turn clockwise to increase pressure.
•
Turn counterclockwise to decrease pressure.
NOTE: On non-relieving models only, reduce pressure to low-
er than estimated final operating pressure, purge air (open or
actuate air operated equipment to relieve pressure) , adjust
pressure upward as needed.
•
Push to lock.
MAINTENANCE
•
Once the system has been depressurized, the regulator valve
and diaphragm can be replaced without removing the unit
from the line.
