GENERAL SAFETY INFORMATION
Speedaire air pressure regulators are self-relieving and high capacity.
These heavy-duty units are designed for commercial/industrial
applications, providing high air flow while maintaining the set pressure
with minimum pressure drop between the actual air compressor outlet
pressure and the set pressure to tools and equipment.
The device may only be operated in permanently installed air pressure
systems. Improper use or modifications to the device or the use of its
components which are not tested and approved by the manufacturer
may result in unforeseen damage.
Air line regulators are used in a variety of air systems providing
pressurized air to air compressors, spray guns, filters, lubricators,
hoses, etc. Read and understand all safety instructions, installation
instructions and operation instructions before using this unit. Basic
safety precautions should always be followed to reduce the risk of
personal injury and/or property damage.
General Safety inStrUctionS
1. Read all safety instructions. Failure to do so may cause harm to you
and others.
2. Keep children and unauthorized persons away from the device.
Ensure that children are not able to play with the device.
3. Do not overload the device. Do not use the device for purposes for
which it is not intended.
4. Always make sure that the air line is in good condition.
5. Hose and connection should be inspected to avoid any leakage
before use.
6. Residual air in the system needs to be released before service or
repair.
7. Ensure that all connections and supply lines are rated for the required
pressure and air flows.
cAUTION
Polycarbonate bowls are not recommended for
use in atmospheres containing chemicals such
as acetone, benzene, carbon tetrachloride, gasoline, toluene and/or air
compressor systems using synthetic fire-resistant lubricants.

INSTALLATION INSTRUcTIONS
1. Before installation, check whether the connections used match the maximum pressure of the
regulator.
2. Shut off air pressure from air system. Install the regulator vertically or at any angle in the air line.
Ensure that the regulator is installed with inlet/outlet air flow in the proper direction of arrow on
the unit. The regulator should be installed upstream of lubricator(s), and cycling valve(s) in the
air line, and should be as close as possible to the device being serviced.
3. Connect pipes to the inlet and outlet ports using pipe thread sealant tape on male threads only.
When screwing pipes together, prevent ingress of shavings and sealant to the interior of the
unit. Contaminations in the unit may cause it to fail.
4. Make sure that all connections to the regulator are tight and secure.
5. Install a pressure gauge to either of the gauge ports facing the operator. The other gauge port
should be plugged or can be used as an additional air outlet for regulated air.
6. It is recommended that a Speedaire air line filter should be installed upstream of the regulator.
7. The regulator must be installed in such a way that no mechanical force or tension occurs.
