Speedaire Operating Instructions
Cast Iron Series
Introduction
Refer to Figure 1a and Figure 1b to
locate the following items.
Pressure Switch - Auto/Off Switch.
On some models there is no manual
switch. The switch is permanently in
the auto mode. In the AUTO position,
the compressor shuts off automatically
when tank pressure reaches the
maximum preset pressure. In the OFF
position, the compressor will not
operate. This switch should be in the
OFF position when connecting or
disconnecting the power cord from the
electrical outlet or when changing air
tools.
When the pressure switch turns the
motor off you will hear air leaking out
of the pressure switch unloader valve
for a short time. This releases the air
pressure from the discharge tube and
allows the compressor to restart easier.
Regulator - The regulator controls the
amount of air pressure in the air hose.
The air hose is attached at the outlet of
the regulator.

Tank Drain valve - This valve is located
on the bottom of the tank. Use this
valve to drain moisture from the tank
daily to reduce the risk of corrosion.
Reduce tank pressure below 10 psi,
then drain moisture from tank daily to
avoid tank corrosion. Drain moisture
from tank(s) by opening the drain valve
located underneath the tank.
Tank Pressure Gauge - Indicates
amount of air pressure stored in tank.
Hose Pressure Gauge - Indicates
amount of air pressure in hose used to
operate tools. This pressure is increased
or decreased by the regulator.
