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
for thermal protection (See Figure 4).

WARNING

WARNING
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)
On some 30 gallon models a wall cable
is provided and should be installed.
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
the weight of the compressor.
Never install a
shut-off valve
between the compressor pump and the
tank. Personal injury and/or equipment
damage may occur.

Introduction
(Con’t)
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.
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.
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)
The compressor feet
MUST
be bolted
to a flat, even, concrete floor or
separate concrete foundation.
Vibration isolators
must be
used
between the tank leg and the floor
(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.
