Installation
Do not operate
unit if damaged during shipping,
handling or use. Operating unit
if damaged may result in injury.
1. Permanently installed
compressors must be located
in a clean, well ventilated dry
room so compressor receives
adequate supply of fresh,
clean, cool and dry air.
It is recommended that a
compressor, used for
painting, be located in a
separate room from that area
wherein body sanding and
painting is done. Abrasive
articles or paint, found to have
clogged the air intake filters
and intake valves, shall
automatically void warranty.
2. Compressors should never
be located so close to a wall or
other obstruction that flow of
air through the fan bladed
flywheel, which cools the
compressor, is impeded.
Permanently mounted units
should have flywheel at least
12" from wall.
For Service and Warranty, Call: 1-888-303-1344
3. Place stationary compressors
on firm level ground or flooring.
Permanent installations require
bolting to floor, and bolt holes
in tank or base feet are provided.
Before bolting or lagging
down, shim compressor level.
Avoid putting a stress on a
tank foot by pulling it tightly
down to floor. This will only
result in abnormal vibration,
and possible cracking of
Air Receiver. As an alternative,
install unit on optional
vibro-isolator pads. Tanks
bolted directly to a concrete
floor without padding will
not be warranted against
cracking.
Do not install
isolating valves between
compressor outlet and air
receiver. This will cause
excessive pressure if valve is
closed and cause injury and
equipment damage.
Always use an
air pressure regulating device
at the point of use. Failure to
do so can result in injury or
equipment damage.

Electrical Power Supply
It is essential that the power
supply and the supply wiring are
adequately sized and that the voltage
correspond to the unit specifications.
Branch circuit protection must be
provided at installation as specified in
the National Electrical Code.
All wiring should be performed by
a licensed electrician or electrical
contractor. Wiring must meet
applicable codes for area of installation.
The table below gives recommended
wire sizes based on the 1999 NEC.
All models have a factory mounted and
wired magnetic starter. The starter
provides motor overload protection.
See Figure 1-1 for wiring diagram.
Electrical connections exist between
the pressure switch and the starter.
