Pressure Relief Valve
L
pressure relief valve is an
automatic pop valve. Each valve
I
is properly adjusted for the
S
maximum pressure permitted by
H
tank specifications and working
pressure of the unit on which it is
installed. If it should pop, it will
be necessary to drain all the air
out of the tank in order to reseat
properly. Do not readjust.
Tank Drain Valve
valve is located at bottom of
tank. Open drain valve daily to
drain condensation. Do not open
drain valve if tank pressure
exceeds 25 PSIG. The automatic
tank drain equipped compressor
requires draining manually once a
week.
Pressure Switch
pressure switch is automatic and
will start compressor at the low
pressure and stop when the
maximum pressure is reached. It
is adjusted to start and stop
compressor at the proper
pressure for the unit on which it
is installed. Do not readjust.
Belts:
Drive belts must be kept
tight enough to prevent slipping.
If belts slip or squeak, see V-belt
maintenance in preceding section.
are too tight, overload will be
put on motor and motor

Compressor Valves
If compressor fails to pump air or
seems slow in filling up tank,
disconnect unit from power source
and remove valve plates and clean
thoroughly, using compressed air.
After cleaning exceptional care
must be taken that all parts are
replaced in exactly the same
: The
position and all joints must be tight
or the compressor will not function
properly. When all valves are
reinstalled and connections tight,
close receiver outlet valve for final
test. Valve plate gaskets should be
replaced each time valve sets are
removed from pump.
Hydraulic Unloader
compressor is equipped with an
unloading device operated by oil
: Drain
pressure. When the compressor is
turned off, the unloader will open
resulting in a short burst of air
from the unloader (released
through the intake filter). When
the compressor is restarted, as
soon as the oil pressure reaches
normal operation range (between
15 and 30 PSIG) the unloader valve
closes and the compressor begins
: The
to pump air. This unloader system
provides loadless starting for
longer motor life and has the
added feature of preventing the
compression of air should the oil
pump fail. In the event of loss of
oil pressure, the compressor
would run in an "unloaded" state
only, until correction of the oil
pressure is made.
If belts
Check Valve
:
closes when the compressor stops
operating, preventing air from
flowing out of the tank through the
pressure release valve. After the
compressor stops operating, if air
continues to escape through the release
valve, it is an indication that the check
valve is leaking. This can be corrected
by removing check valve and cleaning
disc and seat. If check valve is worn
badly, replace check valve.
removing check valve be sure
all air pressure in unit is
released and power is
disconnected. Failure to do so
: This
may result in injury or
equipment damage.
The Interstage Pressure Relief
Valve is provided to protect against
interstage over pressure and is factory
set for maximum pressure of 75 PSIG.
Do Not Reset
If the pressure relief valve pops, it
indicates trouble. Shut down the unit
immediately and determine and correct
the malfunction. Serious damage can
result if not corrected and can lead to
complete destruction of the unit.
Tampering with the interstage pressure
relief valve, or plugging the opening
destroys the protection provided and
voids all warranty.
Lubrication Of Compressor
crankcase to proper level as indicated by
oil sight gauge. Keep crankcase filled as
required by usage. It is recommended
that only Speedaire recip
lubricant be used. This is a 30-weight,
non-detergent industrial oil with rust
and oxidation inhibitors specially
formulated for reciprocating
compressors. Do not mix oil types,
weights or brands.
