GENERAL SAFETY INFORMATION

Speedaire air line filter/regulators are designed to (1) remove airborne
impurities, dirt particles, condensation and oil aerosols from compressed
air through air supply lines, and (2) adjust and maintain air pressure set
at a level which can efficiently operate air tools and other air-operated
equipments. The filter section works by means of centrifugal force and
a filter element while the regulator section is self-relieving and provides
high air flow and maintains the set pressure with minimum pressure
drop between the actual air compressor outlet pressure and the set
pressure to tools and equipments.
The device may only be operated in the permanent installation in
pressured air 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 filter/regulators are used in a variety of air systems which may
go with air compressor, spray gun, 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 filter/regulator.
2. Shut off air pressure from air system. Install the filter/regulator vertically with the bowl
down in the air line. Ensure that the filter/regulator is installed with inlet/outlet air flow
in the proper direction of arrow on the unit. The filter/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.
note: Model 4ZK77 has the word IN stamped next to the air inlet port.
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.
