General Safety

PIPING

Never use plastic

(PVC) pipe for
compressed air. Serious injury or death
could result.

Any tube, pipe, or hose used must have
a pressure rating higher then 150 psi.
Minimum recommended pipe size:

- up to 50 feet long use 1/2”

- greater than 50ft. long use 3/4”

Larger diameter pipe is always better.

All wiring and

electrical
connections must be performed by a
qualified electrician. Installations must
be in accordance with local and
national codes.

GROUNDING

This product must be grounded. If the
unit comes with a factory installed
cord, plug the cord into a properly
sized, grounded outlet. For units that
do not have a factory installed cord,
install permanent wiring from the
electrical source to the pressure switch
with a ground conductor connected to
the grounding screw on the pressure
switch. A properly sized cord with a
ground conductor and plug may also
be installed by the user.

Improperly grounded
motors are shock hazards.
Make sure all the
equipment is properly grounded.

WIRING

Local electrical wiring codes differ from
area to area. Source wiring, plug and
protector must be rated for at least the
amperage and voltage indicated on the
motor nameplate, and meet all electrical
codes for this minimum. Use a slow blow
fuse type T or a circuit breaker.

Overheating, short

circuiting and fire
damage will result from inadequate
wiring.

Motor protection should be used when
a motor built-in thermal overload
protection is not provided. Some 3
phase units require a magnetic starter

WARNING

(Part number MP3445 available
separately). Do not draw bolts tight.
Allow the pads to absorb vibrations. A
flexible coupling should be installed
between the tank and service piping.

This compressor is

extremely top
heavy. The unit must be bolted to the
floor with isolation pads or secured
with the wall cable (if provided)
before operating to prevent
equipment damage, injury or death.

WALL CABLE INSTALLATION

(Provided on some 30 gallon models)

Included with the safety cable are two
lag screws and washers.

1. Place an isolation pad beneath each

foot of the compressor to minimize
vibration.

2. Position the cable through the

baseplate as shown in Figure 3.

3. Place the screws through the

washers then through looped ends
of cable.

4. Secure the screws to a stud within a

framed wall. Use anchors if the wall
is concrete.

Do not secure the

compressor with
toggle bolts into drywall. Drywall
sheeting or plaster will not support

hot during use. To avoid the risk of
severe burns, never touch the
discharge tube.

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.

Belt Guard - Covers the belt, motor
pulley and flywheel.

Tank Drain Valve - This valve is
located on the bottom of the tank. Use
this valve to drain moisture from the
tank daily to reduce the risk of
corrosion.

Reduce tank pressure below 10 psi,
then drain moisture from tank daily to
avoid tank corrosion. Drain moisture
from tank(s) by opening the drain
valve located underneath the tank.

Disconnect, tag and lock
out power source, then
release all pressure from
the system before
attempting to install, service, relocate
or perform any maintenance.

LOCATION

This compressor is
not intended for

outdoor installation.

It is extremely important to install the
compressor in a clean, well ventilated
area where the surrounding air
temperature will not be more than 100°F.

Provide a minimum clearance of 18
inches between the compressor
flywheel or fan to the wall and ensure
clear access to the drain cock to
facilitate condensate drainage.

Do not locate the compressor air inlet
near steam, paint spray, sandblast areas
or any other source of contamination.

MOUNTING

Never use the

wood shipping

skids for mounting the compressor.

FLOOR MOUNTING

(All Units)

On some 30 gallon models a wall cable
is provided and should be installed. If
the unit is not secured with the wall
cable, the compressor feet MUST be
bolted to a flat, even, concrete floor or
separate concrete foundation.

LUBRICATION

THIS UNIT IS

SHIPPED WITHOUT
OIL! Follow lubrication instructions
before operating compressor.

Ensure oil drain extension and cap has
been installed (if included) then remove
the dipstick breather (See Fig. 6) and fill
pump oil according to the chart.

See specification label on air tank for
pump model number and refer to the
chart for the proper oil capacity. Use
SAE 30 industrial grade air compressor
oil or full synthetic motor oil like Mobil
1 10W30. Do not use regular

automotive oil such as 10W-30.

Additives in motor oil can cause valve
deposits and reduce pump life. For
maximum pump life, drain and replace
oil after the first hour of run time.
Proper oil fill level is illustrated in
Figure 6.

START-UP

Do not attach air

tools to open end
of the hose until start-up is completed
and the unit checks OK.

MOISTURE IN COMPRESSED AIR

Moisture in compressed air will form
into droplets as it comes from an air
compressor pump. When humidity is
high or when a compressor is in
continuous use for an extended period
of time, this moisture will collect in the
tank. When using a paint spray or
sandblast gun, this water will be carried
from the tank through the hose, and out
of the gun as droplets mixed with the
spray material.

IMPORTANT: This condensation will
cause water spots in a paint job,
especially when spraying other than
water based paints. If sandblasting, it
will cause the sand to cake and clog the
gun, rendering it ineffective.

A filter in the air line, located as near to
the gun as possible, will help eliminate
this moisture.

1. Pull ring on safety valve and allow
the ring to snap back to normal
position (See Figure 8). This valve
automatically releases air if the tank
pressure exceeds the preset
maximum.

Do not attempt to

tamper with this
valve. This valve should be checked
occasionally. If air leaks after the ring
has been released, or the valve is stuck
and cannot be actuated by the ring, the
safety valve must be replaced.

A large amount of

fast moving air will
be released if this valve is actuated
with pressure in the tank.

2. With motor OFF and unplugged,

clean debris from motor, flywheel,
tank, air lines and pump cooling fins.

DRIVE BELT

Belts will stretch in normal use. Properly
adjusted, a 5-pound force applied to
the belt between the motor pulley and
the pump will deflect the belt about
1/2”(See Figure 9).
