Safety
DEFINITIONS
DANGER!
WILL cause DEATH, SEVERE INJURY or
substantial property damage.
WARNING!
CAN cause DEATH, SEVERE INJURY or substantial property damage.
CAUTION!
WILL or CAN cause MINOR INJURY or
property damage.
GENERAL SAFETY PRECAUTIONS
NEVER directly inhale compressed air.
NEVER over-pressurize the receiver tank or similar vessels
beyond design limits.
NEVER use a receiver tank or similar vessels that fail to
meet the design requirements of the compressor.
NEVER drill into, weld or otherwise alter the receiver tank
or similar vessels.
NEVER remove, adjust, bypass, change, modify or make
substitutions for safety/relief valves, pressure switches or
other pressure control related devices.
NEVER use air tools or attachments without first
determining the maximum pressure recommended for that
equipment.
NEVER point air nozzles or sprayers toward people or
animals.
NEVER touch the compressor pump, motor or engine or
discharge tubing during or shortly after operation. These
parts become hot.
NEVER operate where flammable or explosive liquids
or vapors such as gasoline, natural gas and solvents are
present.
NEVER remove, paint over, or deface decals. Replace any
missing decals.
NEVER operate with guards or shields removed, damaged
or broken.
ALWAYS follow precautions on container labels before
spraying such as paint , insecticide and weed killer.
ALWAYS wear respirator and safety glasses when
spraying.
ALWAYS wear eye protection when operating or servicing
compressor.
BREATHING AIR PRECAUTION
BE air compressors are not designed, intended or
approved for breathing air. Compressed air should not
be used for breathing air applications unless treated in
accordance with all applicable codes and regulations.
Receipt and Inspection
Ensure adequate lifting equipment is available for
unloading and moving your compressor to the
installation site.
NOTE: Lifting equipment must be properly rated for
the weight of the compressor.
Caution! Do not work on or walk under the
compressor while it is suspended. Before signing
the delivery receipt, inspect for damage and missing
parts. If damage or missing parts are apparent, make
the appropriate notation on the delivery receipt, then
sign the receipt. Immediately contact the carrier for an
inspection. All material must be held in the receiving
location for the carrier’s inspection. Delivery receipts
that have been signed without a notation of damage
or missing parts are considered to be delivered
“clear” Subsequent claims are then considered to
be concealed damage claims. Settle damage claims
directly with the transportation company.
If you discover damage after receiving the air
compressor (concealed damage), the carrier must be
notified within 15 day of receipt and an inspection must
requested by telephone with confirmation in writing. On
concealed damage claims, the burden of establishing
that the compressor was damaged in transit reverts
back to the claimant.
Read the compressor nameplate to verify it is the
model ordered, and read the motor nameplate to
verify it is compatible with your electrical conditions.
Make sure electrical enclosures and components are
appropriate.
WARNING! The installation should be made by a
qualified electrician.

1.) Air Filter - Make sure your air filter is clean and
particle free.
2.) Belt Guard - Covers the belt, motor pulley and
flywheel. NEVER operate compressor without the
belt guard or guard cover.
4.) Ball Valve - 1/2” NPT outlet.
5.) Pressure Gauge - Easy to read gauge.
6.) Mount Feet - Use an isolation pad system to
increase your compressor life.
7.) Remote Drain Petcock - This valve is located
on the foot ring of the tank. Use this valve to drain
moisture from the tank daily to reduce the risk of
corrosion.
8.) ASME Safety Valve - This valve automatically
releases air if the tank pressure exceeds the preset
maximum.
9.) Unloader - Device on pressure switch which
allows release of pressurized air between the tank
and compressor so motor does not start under load.
10.) Pressure Switch - Auto/Off Switch - In
the “auto” position, the compressor shuts off
automatically when tank pressure reached the
maximum preset pressure. In the “off” position, the
compressor will not operate. This switch should be in
the “off” position when connecting or disconnecting
the power cord from the electrical outlet. NEVER
attempt to adjust the pressure switch. Tampering with
the pressure switch will void ALL warranties.
11.) Check Valve - One-way valve that allows air
to enter the tank, but prevents air in the tank from
flowing back into the compressor pump.
12.) Discharge Tube - This tube carries compressed
air from the pump to the check valve. This tube
becomes very hot during use. To avoid the risk of
severe burns, never touch the discharge tube.

SELECTING A LOCATION
Select a well lit indoor area with plenty of space for proper
cooling air flow and accessibility. Locate the compressor at
least 15 inches (38 cm) from walls, and make sure the power
supply is clearly identified and accessible.
Temperature. Ideal operating temperatures are between 40º
and 100ºF (4º and 37ºC). If temperatures consistently drop
below 32ºF (0ºC), install the compressor inside a heated
building. If this is not possible, you must protect safety/relief
valves and drain valves from freezing.
CAUTION!
NEVER operate in temperatures below 15ºF (-9ºC) or
above 125ºF (52ºC).
Humid Areas. In frequently humid areas, moisture may form
in the pump and produce sludge in the lubricant, causing
running parts to wear out prematurely. Excessive moisture is
especially likely to occur if the compressor is located in an
unheated area that is subject to large temperature changes.

INSTALLING DISCHARGE PIPING
OUTLET
VALVE
00855
CAUTION! If you will be using synthetic lubricant, all
downstream piping material and system components
must be compatible. Refer to suitable list on page 6.
General Requirements. The piping, fittings, etc. must
be certified for at least 4 times the working pressure. Use
hard-welded, threaded steel or copper pipes and cast
iron fittings that are certified safe for the compressors
discharge pressure and temperature. DO NOT USE PVC
PLASTIC. Use pipe thread sealant on all threads, and
make up joints tightly to prevent air leaks.
Main Air Distribution Line. The main compressed air
distribution line should be of sufficient size to minimize
the pressure drop between the air supply and the point
of use. Slope the piping downward in the direction of
air flow to aid in the removal of condensation at all drain
points along the line. The piping must be as short and
direct as possible, and adequately braced.
Drip Legs. A drip leg is a pipe extending downward
from the main line to collect condensation. Drip legs
should be at the lowest points in the air line and at any
point where the leg goes around an obstruction. A drain
valve should be installed at the bottom of each drip leg.
Drop Legs. A drop leg is piping originating from the
main air distribution line that feeds air to an outlet for
tools or other air operated devices. Drop legs are taken
off the top of the main line so that condensation does
not easily flow into them. Drop legs should be designed
so that the air outlet comes off the side of the drop leg,
rather than the bottom. By doing this, the condensation
which is carried from the main line collects below the
outlet and prevents moisture from entering the tool or
device using the air. A drain valve should be installed on
the bottom of each drop leg.

one size larger than the connection, as short and direct
as possible, secured tightly and routed to a suitable drain
point. Condensation must be disposed of in accordance
with local, state, and federal laws and regulations.
Wiring Installation
WARNING! If an aftercooler, check valve, block valve,
or any other restriction is added to the compressor
discharge, install a properly sized ASME approved
safety/relief valve between the compressor discharge
and the restriction.

General. The motor rating, as shown on the motor
nameplate, and the power supply must have compatible
voltage, phase and hertz characteristics.
Wire Size. The electrical wiring between the power
supply and electric motor varies according to motor
horsepower. Power leads must be adequately sized to
protect against excessive voltage drop during start-up.
Information for selecting proper wire size should be
provided by a qualified electrician. If other electrical
equipment is connected to the same circuit, the total
electrical load must be considered in selecting the
proper wire size. Do not use undersized wire.
NOTE: On units requiring a motor starter, connect line
power to the starter. DO NOT connect the line power to
the pressure switch.
Magnetic Starter. If the motor installed on your
compressor has a motor reset button, it does not
require a magnetic starter. If the motor does not have
this button, connect the power leads to the starter
located under the compressor top plate.
Circuit Breaker. Refer to the National Electric
Code to determine the proper circuit breaker rating
required. When selecting a circuit breaker, remember
the momentary starting current of an electric motor is
greater than its full load current. Time delay or “slowblow” circuit breakers are recommended.
WARNING! The installation should be made by
a qualified electrician. If the products must be
reconnected for use on different types of circuits, the
re-connection should be made by qualified personnel.
