Gast DOA-P504-BN - Manual (Page 2)

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. The metal capacitor shell must
be grounded.
Determine the correct overload setting required to
protect the motor (see motor starter manufacturerʼs
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 must be able to withstand the motorʼs 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.
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 donʼt follow
instructions.
You can be killed or seriously injured if you donʼt 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.
Accessories

DANGER
Plumbing
Remove plugs from the IN and OUT ports. Connect
with pipe and fittings that are the same size or larger
than the productʼs threaded ports. Be sure to connect
the intake and exhaust plumbing to the correct inlet and
outlet ports. Ports will not support the weight of the
plumbing.
Install relief valves and gauges at inlet or outlet, or both,
to monitor performance. Check valves may be required
to prevent back streaming through the pump.
