Installation (Continued)
pipinG
Never use plastic (PVC) pipe for compressed air.
Serious injury or death could result.
Any tube, pipe or hose connected to the unit must be able to
withstand the temperature generated and retain the pressure� All
pressurized components of the air system must have a pressure
rating of 200 psi or higher� Incorrect selection and installation
of any tube, pipe or hose could result in bursting and injury.
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 control 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 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�
WirinG (see page 8 for wiring diagrams)
All wiring and electrical connections must be
performed by a qualified electrician familiar
with induction motor controls. 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 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�

NOTE
: If using 208 volts single phase, make sure the motor
name plate states it is rated for 208 volts single phase� 230 volt

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.
