Installation (Continued)
TANK MOUNTING
The tank should be bolted into a flat,
even, concrete floor or on a separate
concrete foundation. Vibration isolators
should be used between the tank leg
and the floor. Model 4C974 isolator pads
are recommended. When using isolator
pads, do not draw bolts tight. Allow
the pads to absorb vibrations. When iso-
lators are used, a flexible hose or cou-
pling should be installed between the
tank and service piping.
Failure to properly
install the tank can lead
to cracks at the welded
joints and possible
bursting.

pressed air. Serious injury or death
could result.
Any tube, pipe or hose connected to the
unit must be able to withstand the tem-
perature generated and retain the pres-
sure. All pressurized components of the
air system must have a pressure rating
higher than or equal to the 200 psi for
two-stage compressors or 150 psi for sin-
gle stage compressors ASME safety valve
setting. Incorrect selection and installa-
tion of any tube, pipe or hose could
result in bursting and injury. Connect pip-
ing system to tank using the same size fit-
ting 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

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 under
ground lines below the frost line and
avoid pockets where condensation can
gather and freeze.
