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.
Correct installation is your responsibility.
Make sure
you have the proper installation conditions and that
installation clearances do not block air flow.
Blocking air flow over the product in any way can
cause the product to overheat.
Mounting
This product can be installed in any orientation.
Mounting the product to a stable, rigid operating surface
and using shock mounts will reduce noise and vibration.
INSTALLATION
Motor Control
It is your responsibility to contact a qualified
electrician and 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 attached to the product provides
required electrical information. Check that power
source is correct to properly operate the dual-voltage
motor.
It is your responsibility to operate this product at
recommended pressures or vacuum duties and
room ambient temperatures.
Start Up
If motor fails to start or slows down significantly under
load, shut off and disconnect from power supply. Check
that the voltage is correct for motor and that motor is
turning in the proper direction. Vane life will be
drastically reduced if motor is not operating properly.
Vanes can break or be damaged if motor/pump runs in
the wrong direction.
Accessories
The product’s intake and exhaust filters will provide
adequate filtration in most applications. Consult your
Gast representative for additional filter
recommendations. Install relief valves and gauges at
inlet or outlet, or both, to monitor performance. Check
valves are required to prevent back streaming through
the pump.
