9 - ENG
5. Place the washers (supplied) between the floor and air compressor feet, see
figure. If needed use shims to level the unit.
6. Place the 3/8" lag screws through the air compressor feet, washers and into
the anchors.
7. Torque 3/8" lag screws to 7-10 ft.-lbs (9.5-13.5 Nm).
WIRING INSTRUCTIONS
Improper electrical installation of this product may void its warranty
and your fire insurance. Have circuit wiring performed by qualified personnel such
as a licensed electrician who is familiar with the current national electrical code and
any prevailing local electrical codes.
Risk of electrical shock. Improper electrical grounding can
result in electrical shock. The wiring should be done by a qualified
electrician.
A qualified electrician needs to knows the following before wiring:
1. The amperage rating of the electrical box should be adequate. Refer to the
Specifications, in the parts manual, for this information.
2. The supply line should have the same electrical characteristics (voltage, cycle,
phase) as the motor. Refer to the motor nameplate, on side of motor, for this
information.
NOTE: The wiring must be the same as the motor nameplate voltage plus or
minus 10%. Refer to local codes for recommended wire sizes, correct wire size,
and maximum wire run; undersize wire causes high amp draw and overheating to
the motor.
Risk of electrical shock. Electrical wiring must be located
away from hot surfaces such as manifold assembly, compressor outlet tubes,
heads, or cylinders.
GROUNDING INSTRUCTIONS
This product should be connected to a metallic, permanent wiring system, of an
equipment-grounding terminal or lead on the product.
VOLTAGE AND CIRCUIT PROTECTION
Refer to the Specifications for the voltage and minimum branch circuit
requirements.
Certain air compressors can be operated on a 15 amp circuit if the
following conditions are met.
1. Voltage supply to circuit must comply with the National Electrical Code.
2. Circuit is not used to supply any other electrical needs.
3. Extension cords comply with specifications.
4. Circuit is equipped with a 15 amp circuit breaker or 15 amp time delay fuse.
NOTE: If compressor is connected to a circuit protected by fuses, use only
time delay fuses. Time delay fuses should be marked "D" in Canada and "T"
in the US.
If any of the above conditions cannot be met, or if operation of the compressor
repeatedly causes interruption of the power, it may be necessary to operate it from
a 20 amp circuit. It is not necessary to change the cord set.
AIR DISTRIBUTION SYSTEM
Risk of bursting. Plastic or PVC pipe is not designed for use
with compressed air. Regardless of its indicated pressure rating, plastic pipe
can burst from air pressure. Use only metal pipe for air distribution lines.
The next figure represents a typical air distribution system. The following are tips
to remember when setting up the air compressor’s air distribution system.
