INSTALLATION INSTRUCTIONS (CONTINUED)
Piping
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.
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 11 for wiring diagrams)
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 motors. Refer to
motor name plates 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.
Never use plastic (PVC) pipe for compressed air. Serious injury or death could
result.
