Operating Instructions
Installation
(Continued)
Connect piping system to tank using the
same size fitting as the discharge port.
INSTALLING A SHUT-OFF VALVE
A shut-off valve should be installed on
the discharge port of the tank to con-
trol the air flow out of the tank. The
valve should be located between the
tank and the piping system.
Never install a
shut-off valve
between the compressor pump and the
tank. Personal injury and/or equipment
damage may occur. Never use reducers
in discharge piping.
When creating a permanently installed
system to distribute compressed air,
find the total length of the system and
select pipe size from the chart. Bury
underground lines below the frost line
and avoid pockets where condensation
can gather and freeze.
Apply air pressure to the piping installa-
tion and make sure all joints are free
from leaks BEFORE underground lines
are covered. Before putting the compres-
sor into service, find and repair all leaks
in the piping, fittings and connections.

WIRING
All wiring and
electrical connec-
tions must be performed by a qualified
electrician. Installations must be in
accordance with local and national
codes.
Overheating, short
circuiting and fire
damage will result from inadequate
wiring.
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 electri-
cal characteristics (voltage, cycles
and phase) as the motor.

3. The line wire is the proper size and
that no other equipment is operat-
ed 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 ordi-
nances. If so, the larger size wire should
be used to prevent excessive line volt-
age drop. The additional wire cost is
very small compared with the cost of
repairing or replacing a motor electri-
cally "starved" by the use of supply
wires which are too small.

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.
MOTOR HOOKUP AND STARTER
INSTALLATION
Branch circuit protection must be provid-
ed as specified in National Electrical
Code, Chapter 2, "Wiring Design and
Protection." Article 210, using the applic-
able article "For Motors and Motor
Controllers," (Article 430, Table 430-1 52).

Motor protection must be used when
built-in motor thermal overload protec-
tion is not provided. Some single phase
and three phase units require a mag-
netic starter as illustrated in Figures 2
and 3.
