Gast 20R 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 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.
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.
WA RNING
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.
Accessories
Install gauges in the lines to monitor performance. A
relief valve can be installed at the inlet or outlet, or both.
Consult a Gast representative for performance limitations.
If operated in a dirt-contaminated atmosphere, a suitable
filter should be used to ensure long service. For
recommendations, contact a Gast representative.
Plumbing
Connect with pipe and fittings that are the same size or
larger than the productʼs ports. Be sure to connect the
intake and exhaust plumbing to the correct inlet and
outlet ports. Ports will not support plumbing.
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 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 motors.
NOTE: Standard AC models have either a single-shot
or resettable thermal overload. If a motor with a single-
shot thermal overload is tripped, it cannot be restarted.
A motor with a resettable thermal overload can restart
once the motor cools down. The following could
possibly cause an overload: a power spike, operating at
incorrect voltage, the motor unable to run, or the unit
over-heating.
WARNING
Beware of any exposed movable parts. Proper guards
should be in place to prevent severe personal injury or
death.
