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
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.
Accessories
The product’s internal intake and exhaust filters will
provide adequate filtration in most applications. Check
filters periodically and replace when necessary. 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.
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 to 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.
Electrical Connection
OPERATION
Model with a power supply cord:
This product must be grounded. For either 120-volt or
220/240-volt circuits connect power supply cord
grounding plug to a matching grounded outlet. Do not
use an adapter. (See DIAGRAM A)
In the event of an electrical short circuit, grounding
reduces the risk of electric shock by providing an
escape wire for the electric current. This product may
be equipped with a power supply cord having a
grounding wire with an appropriate grounding plug.
The plug must be plugged into an outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
Check with a qualified electrician or serviceman if the
grounding instructions are not completely understood,
or if you are not sure whether the product is properly
grounded. Do not modify the plug provided. If it will
not fit the outlet, have the proper outlet installed by a
qualified electrician.
Model that is permanently wired:
This product must be connected to a grounded,
metallic, permanent wiring system, or an equipment
grounding terminal or lead on the product.
Power supply wiring must conform to all required safety
codes and be installed by a qualified person. Check
that supply voltage agrees with that listed on product
nameplate.
Extension cords:
Use only a 3-wire extension cord that has a 3-blade
grounding plug. Connect extension cord plug to a
matching 3-slot receptacle. Do not use an adapter.
Make sure your extension cord is in good condition.
Check that the gage wire of the extension cord is the
correct size wire to carry the current this product will
draw.
Injury Hazard
Install proper safety guards as needed. Pumps with
glass jars need safety guards to protect against
breaking glass.
Use only recommended air handling parts
acceptable for pressure not less than 70 psi.
Keep fingers and objects away from openings and
rotating parts.
When provided, motor terminal covers must be in
place for safe operation.
Check that coupling guard and shroud are in place
before operating.
Product surfaces may become hot during operation,
allow product surfaces to cool before handling.
Do NOT direct air stream at body. Air stream from
product may contain solid or liquid material that can
result in eye or skin damage, wear proper eye
protection.
