WARNING
Electrical Shock Hazard
WARNING
DANGER
Your safety and the safety of others
is extremely important.
We have provided many important safety messages
in this manual and on your product. Always read
and obey all safety messages.
This is the safety alert symbol. This symbol
alerts you to hazards that can kill or hurt you and
others. The safety alert symbol and the words
“DANGER” and “WARNING” will precede all safety
messages. These words mean:
You will be killed or seriously injured if you don’t
follow instructions.
You can be killed or seriously injured if you don’t
follow instructions.
All safety messages will identify the hazard, tell you
how to reduce the chance of injury, and tell you
what can happen if the safety instructions are not
followed.

Plumbing
To prevent air flow restriction, use pipe and fittings that are
the same size or larger than the threaded ports of the pump.
The ports are marked "IN" and "OUT". If the distance is
great, use lines with a larger diameter than the connections.
Give lines a uniform slope, place drain cock at low point,
and avoid extra elbows. For ease of servicing, use a union
or hose with clamps near the pump (a hose helps eliminate
noise and vibration). If a vacuum/pressure supply tank is
used, slope the line towards tank, provide a drain at the
bottom, and place a check valve between the tank and
pump so the pump will not run backwards when turned off.
Accessories
Intake and exhaust filters are external to the pump and will
provide adequate filtration for most applications. Check
filters periodically and replace when necessary. Consult a
Gast Representative for additional filter recommendations.
Install relief valves and gauges at the inlet or outlet, or both,
to monitor performance. Check valves may be required to
prevent backstreaming through the pump.
Motor Control
It is your responsibility to contact a qualified
electrician to assure that the electrical installation is
adequate and in conformance with all national and local
codes and ordinances.
Determine the correct overload setting required to
protect the motor (see motor starter manufacturer’s
recommendations). Select fuses, motor protective
switches or thermal protective switches to provide
protection. Fuses act as short circuit protection for the
motor, not as protection against overload. Incoming line
fuses help to withstand the motor’s starting current.
Motor starters with thermal magnetic overload or circuit
breakers protect motor from overload or reduced
voltage conditions.
The wiring diagram supplied with the product provides
required electrical information. Check that power
source is correct to properly operate the dual-voltage
motors.
WARNING
Injury Hazard
Only pump air, never allow this pump to be used
with any other gasses, fluids, particles, solids,
COMBUSTIBLE SUBSTANCES or any substance
mixed with air.
CAUTION Do not lift unit by fan shrouds. Unit
should be lifted by means of eye bolt.
CAUTION Do not block cooling air flow over
pump in any way.
WARNING Some models are equipped with
glass jars. Proper measures should
be taken to guard against glass
fragmenting or braking if an
alternative material is not used. If
hazard is ignored severe personal
injury or death can occur.
Mounting Pump
Pump base should be anchored to either a metal surface
such as a shelf, floor or another piece of machinery. To
save time and avoid inconvenience, position pump to
provide easy access to all lubricators, filters and mufflers.
