Introduction

Air compressor units are intended to provide compressed air to power pneumatic tools, operate spray guns
and supply air for pneumatic valves and actuators. The pumps supplied with these units have oil lubricated
bearings. A small amount of oil carryover is present in the compressed air stream. Applications requiring air
free of oil vapor should have the appropriate filters installed. The air compressor units are to be mounted
per the instructions provided on a solid floor. Any other use of these units will void the warranty and the
manufacturer will not be responsible for problems or damages resulting from such misuse.

Tank Mounting

The tank should be bolted into a flat, even, concrete floor or on a
separate concrete foundation. Vibration isolators should be used
between the tank leg and the floor. Model MP345700AJ isolator
pads are recommended for installation.

When using isolator pads, do not draw bolts tight. Allow the pads
to absorb vibrations. When isolators are used, a flexible hose or
coupling should be installed between the tank and service piping.

Failure to properly install the tank can lead to

cracks at the welded joints and possible bursting.

piping, fittings and connections.

Wiring

All wiring and electrical connections must be performed by a qualified electrician

familiar with induction motor controls. Installations must be in accordance with local and

national codes.

Wiring must be installed in accordance with National Electrical Code and local codes and standards that
have been set up covering electrical apparatus and wiring. These should be consulted and local ordinances
observed. Be certain that adequate wire sizes are used, and that:

1. Service is of adequate ampere rating.

2. The supply line has the same electrical characteristics (voltage, cycles and phase) as the motor. Refer to
motor name plate for electrical ratings and specifications.

3. The line wire is the proper size and that no other equipment is operated from the same line. The chart
gives minimum recommended wire sizes for compressor installations.

Recommended wire sizes may be larger than the minimum set up by local ordinances. If so, the larger size
wire should be used to prevent excessive line voltage drop. The additional wire cost is very small compared
with the cost of repairing or replacing a motor electrically “starved” by the use of supply wires which are too
small.

INSTALLATION INSTRUCTIONS (CONTINUED)

Grounding

Improperly grounded electrical components are shock hazards. Make sure all the

components are properly grounded to prevent death or serious injury.

This product must be grounded. Grounding reduces the risk of electrical shock by providing an escape wire
for the electric current if short circuit occurs. This product must be installed and operated with a power cord
or cable that has a grounding wire.

Breakers and Fuses

The entire electrical system should be checked by a certified electrician. Time delay breakers and fuses are
required for this compressor. A tripped breaker or blown fuses may indicate a direct short to ground, high
current draw, improper wiring, incorrect fuse or breaker size and/or type. This needs to be evaluated by a
certified electrician.

OPERATING INSTRUCTIONS (CONTINUED)

Recommended Break-In Period

The compressor should be run continuously at 90 PSI or lower for one hour to allow proper seating of the
piston rings.

1. Open drain cock completely and run the compressor for 60 minutes.

2. Turn off the compressor and close drain cock. The compressor is now ready for use.

If the compressor is run under humid conditions for short
periods of time, the humidity will condense in the crankcase
and cause the oil to look creamy. Oil contaminated by
condensed water will not provide adequate lubrication and
must be changed immediately. Using contaminated oil will
damage bearings, pistons, cylinders and rings and is not
covered under warranty. To avoid water condensation in the
oil, periodically run the compressor with tank pressure near
120 psi for single stage compressors by opening the drain valve
or an air valve connected to the tank or hose. Run the pump
for an hour at a time at least once a week or more often if the
condensation reoccurs.

IMPORTANT: Change oil after first 50 hours of operation and
every 200 hours afterwards

Pressure Switch, Start - Stop

NOTE: Single stage compressors have a maximum operating pressure of 135 psi. Do not alter pressure
settings on control components above this limit.

The compressor unit starts and stops based on preset pressure switch settings of 105 psi cut-in and 135 psi
cut-out. The pressure switch contains an unloader which is a small valve that vents air to allow the motor to
start easily (see Figure 7).

The unloader valve on the pressure switch should hiss for a short period of time when the compressor shuts
off. This relieves the head and the exhaust tubing of any pressure and allows the compressor to start under
no load. Because compressors have high starting torque the unloader is necessary for proper starting of the
compressor.

The check valve is a one way valve that keeps the air in the tank when the unit shuts off. The easiest way
to determine if the check valve is working properly is to make sure that the pressure switch unloader quits
hissing after the compressor shuts off. The hissing should last for several seconds and then quit.

Crankcase Breather

During severe operating conditions or initial start-up, some oil may accumulate at the crankcase breather
opening. This is normal and will diminish as the pump accumulates run time and the piston rings become
fully seated.

Draining Tank

Condensate must be drained from the tank daily, use
manual tank drain (see Figure 8).

INSTALLATION

Disconnect, tag and lock out power source then release all pressure from the system before

attempting to install, service, relocate or perform any maintenance.

In order to maintain efficient operation of the compressor system, check the air filter and oil level before
each use. The ASME safety valve should also be checked daily (see Figure 9). Pull ring on safety valve and
allow the ring to snap back to normal position. This valve automatically releases air if the tank pressure
exceeds the preset maximum. If air leaks after the ring has been released, or the valve is stuck and cannot
be actuated by the ring, the ASME safety valve must be replaced.

TROUBLESHOOTING OPERATION

Drain liquid from tank daily.

The tank should be carefully inspected at a minimum of once a year. Look for cracks forming near the
welds. If a crack is detected, remove pressure from tank immediately and replace.

Compressor Lubrication

See Installation. Add oil as required. The oil should be changed every three months or after every 200 hours
of operation; whichever comes first.

If the compressor is run under humid conditions for short periods of time, the humidity will condense in
the crankcase and cause the oil to look creamy. Oil contaminated by condensed water will not provide
adequate lubrication and must be changed immediately. Using contaminated oil will damage bearings,
pistons, cylinders and rings and is not covered under warranty. To avoid water condensation in the oil,
periodically run the compressor with tank pressure near 120 psi for single stage compressors by opening the
drain cock or an air valve connected to the tank or hose. Run the pump for an hour at a time at least once a
week or more often if the condensation reoccurs.

IMPORTANT: Change oil after first 50 hours of operation.

Air Filter

Never run the compressor pump without an intake air filter or
with a clogged intake air filter. The air filter element should be
checked monthly (see Figure 10). Operating compressor with
a dirty filter can cause high oil consumption and increase oil
contamination in the discharge air. If the air filter is dirty it must
be replaced.
