Piping / Tank Installa on
1. Place tank feet on 1/4 in. thick rubber pads.
Thicker padding will increase vibra on and
the possibility of cracking the tank or other
unit damage.
Do not place unit on dirt
fl
oor
or uneven surface.
2. Fasten anchor bolts snugly but do not over ht-
en so normal vibra on will not damage unit.
Compressor unit is top heavy and
must be bolted to solid,
fl
at
surface to avoid falling and premature pump wear.
Splash lubrica on will not operate properly if unit
is not level.
3. Use a
fl
exible connector between compressor
(Pipe size shown in. inches)

vibra on, unit damage and pump wear.
4. Install appropriate ASME code safety valves
and make sure piping system is equipped with
adequate condensate drains. See

gure 2.
Refer to
fi
gure 3 for recommended closed loop
installa on.

Never install a shut-o
ff
valve such as
a glove or gate valve, between the
pump discharge and the air tank
unless a safety valve is installed in
the line between valve and pump.
5. Make sure any tube, pipe or hose connected
to the unit can withstand opera ng tem-
peratures and retain pressure.
Never use plas c (PVC) pipe for
compressed air. Serious injury or
death could result.
6. Never use reducers in discharge piping. Keep
all piping and
fi
ngs the same size in the
piping system.

7. For permanent installa ons of compressed
air systems, determine total length of sys-
tem and select correct pipe size. Make sure
underground lines are buried below frost line
and avoid areas where condensa on could
build up and freeze.
8. Test en re piping system
before
underground
lines are buried. Be sure to
fi
nd and repair
all leaks before using compressor.
Never exceed recommended pressure
or speed while opera ng compressor.
Electronic Auto Drain
(if equipped)
One auto drain can be used for mul ple compres-
sor units. Install necessary piping with appropriate
fi
ngs.
