Gast 1534 Series Oilless Vacuum Pumps and Compressors - 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.
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.
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
The product’s internal intake and exhaust filters will
provide adequate filtration in most applications. Check
filters periodically and replace when necessary. The 32
and 34 Series models have internal intake and exhaust
filters. Some models in the 31 and 33 Series have
external intake and exhaust filters. All units should
have an intake and exhaust filter to prevent
contaminants from entering the pump or the pneumatic
system. Please 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.
Electrical Connection
Brush type DC motors will need replacement brushes
after 500 hours to 1500 hours of operation. Contact
your Gast Distributor/Representative for replacement
brushes. Positive leads are red (+) and negative leads
are black (–).
Brushless DC motors with controls are preset from the
factory for single direction, uni-speed operation.
Positive leads are red (+) and negative leads are black
(–).
MFD and voltage ratings required for capacitors vary
with motor. If you are unsure of what capacitor is
required for your motor, contact your Gast
Distributor/Representative.
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.
INSTALLATION
Your safety and the safety of others
