INSTALLATION INSTRUCTIONS (CONTINUED)
Installing A Shut-Off Valve
A shut-off valve should be installed on the discharge port of the tank to control the air flow out of the tank. The
valve should be located between the tank and the piping system.

Wiring
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.
Make sure voltage is correct with the motor wiring.
NOTE: If using 208 volts single phase, make sure the motor name plate states it is rated
for 208 volts single phase. 230 volt single phase motors do not work on 208 volts unless
they have the 208 volt rating.

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.

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
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 installation and make sure all joints are
free from leaks BEFORE underground lines are covered. Before putting
the compressor into service, find and repair all leaks in the piping, fittings
and connections.
All wiring and electrical connections must be performed by a qualified electrician
familiar with induction motor controls. Installations must be in accordance with
Overheating, short circuiting and fire damage will result from inadequate wiring.
