6. Slide the bottom pipe clamps into the Unistrut already
attached to the system. Use appropriate socket & channel
locks/adjustable wrench to secure clamp bolt & nut.
7. If using, attach the supplied hose whip to the 3/4” threaded
outlet. Secure flange nut on hose whip using adjustable
wrench. Remove the blue plug from the compressor head
and install the filter, hand tightening.
8. Complete the installation by having a certified electrician
make the electrical connections. This compressor system
provides standard electrical conduit connection.
Once finished, turn the system on and ensure it pressurizes
the system and turns off once pressure setting is reached.
If needed, the pressure switch can be adjusted using the
provided instructions.
MOTOR CONTROL
It is your responsibility to contact a qualified electrician
and assure that the electrical installation is adequate and in
conformance with all national and local codes and ordinances.
Determine the correct overload setting required to protect the
motor (see motor starter manufacturer’s recommendations).
Select fuses, motor protective switches or thermal protective
switches to provide protection. Fuses act as short circuit
protection for the motor, not as protection against overload.
Incoming line fuses must be able to withstand the motor’s
starting current. Motor starters with thermal magnetic overload
or circuit breakers protect motor from overload or reduced
voltage conditions.
The wiring diagram supplied with the product provides required
electrical information. Check that power source is correct to
properly operate the motor.
WARNING
Electrical Shock Hazard
This product must be properly grounded.
Check the condition of the power supply wiring.
Do not permanently connect this product to wiring that

of this product.
Failure to follow these instructions can result in death, fire,
or electrical shock.
Model that is Permanently Wired
This product must be connected to a grounded, metallic,
permanent wiring system, or an equipment grounding terminal or
lead on the product.

and be installed by a qualified person. Check that supply voltage
agrees with that listed on product nameplate.
OPERATION
WARNING
Injury Hazard
Install proper safety guards as needed.
Keep fingers and objects away from openings and
rotating parts.
When provided, motor terminal covers must be in place
for safe operation.
Product surfaces become very hot during operation,
allow product surfaces to cool before handling.
Air stream from the product may contain solid or liquid
material that can result in eye or skin damage, wear proper
eye protection.
Wear hearing protection. Sound level from motor may
exceed 70 dBA.
Failure to follow these instructions can result in burns,
eye injury, or other serious injury.
It is your responsibility to operate this product at recommended
pressures and room ambient temperatures. Do not start against a
pressure load.
Start Up
WARNING
This motor is thermally protected and may restart
after cooling.
If motor fails to start or slows down significantly under load, shut
off and disconnect from power supply. Check that the voltage
is correct for motor and that motor is turning in the proper
direction. Check the switch for damage. If so equipped, the
thermal protection switch has tripped, the motor can restart after
cooling.
