Gast 55R Series - Manual (Page 2)

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.
WARNING
DANGER
INSTALLATION
Ꮨ
Disconnect electrical power at the circuit breaker
or fuse box before installing this product.
Install this product where it will not come into
contact with water or other liquids.
Install this product where it will be weather
protected.
Electrically ground this product.
Failure to follow these instructions can result in
death, fire or electrical shock.
WARNING
Electrical Shock Hazard
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
Mounting the product to a stable, rigid operating surface
and using shock mounts will reduce noise and vibration.
Mounting the control module (DC unit only)
Controller can be damaged by static electricity, handle
appropriately.
Mount the speed control module in a protected location
near the pump. Do not block the flow of cooling air over
the module in any way. Plug the 3-wire and 5-wire
connectors on the pump into corresponding connectors
on the speed control module (see DC wiring diagram).
Accessories
Intake filters are required for dirty environments. 1/8” port
required (Gast Part No. B300Q). Check filters
periodically and replace when necessary. Consult your
Gast Distributor/Representative for additional filter
recommendations.
Plumbing
Remove plugs from the IN and OUT ports. Connect
with pipe and fittings that are the same size or larger
than the product’s threaded ports. Be sure to connect
the intake and exhaust plumbing to the correct inlet and
outlet ports. Ports will not support 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.
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 must be grounded.
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 must be able 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.
