INSTALLATION

c

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

WARNING

DANGER

Your safety and the safety of others

i

s 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.

Correct installation is your responsibility. Make sure you

have the proper installation conditions and that
installation clearances do not block air flow. Proper
guards should be installed to prevent contact with
moveable parts of this pump. Do Not lift the unit by the
fan shroud.

Blocking air flow over the product in any way can cause
the product to overheat.

Mounting

Position the mounting the product to a stable, rigid
operating surface and using shock mounts will reduce
noise and vibration.

Plumbing

To prevent air flow restriction, use pipe and fittings that are
the same size or larger than the threaded ports of the pump.
T

he ports are marked "IN" and "OUT". If the distance is
great, use lines with a larger diameter than the connections.
Give lines a uniform slope, place drain cock at low point,
and avoid extra elbows. For ease of servicing, use a union
or hose with clamps near the pump (a hose helps eliminate
noise and vibration). If a vacuum/pressure supply tank is
used, slope the line towards tank, provide a drain at the
bottom, and place a check valve between the tank and
pump so the pump will not run backwards when turned off.

Accessories

Intake and exhaust filters are external to the pump and will
provide adequate filtration for most applications. Check
filters periodically and replace when necessary. Consult a
Gast Representative for additional filter recommendations.
Install relief valves and gauges at the inlet or outlet, or both,
to monitor performance. Check valves may be required to
prevent backstreaming 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 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 help 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.

MAINTENANCE

c

Disconnect electrical power supply cord before
performing maintenance on this product.

If product is hard wired into system, disconnect
electrical po

wer at the circuit breaker or fuse box

before performing maintenance on this product.

F

ailure to follow these instructions can result in

death, fire or electrical shock.

Electrical Shock Hazard

WARNING

Start Up

If pump is extemely cold, let it warm up to room
temperature before starting. If motor fails to start or
slows down significantly under load, shut off and
disconnect from power supply. Check that the voltage
is correct for motor and that motor is turning in the
proper direction. Turning in the wrong direction will
drastically reduce vane life. Vane life will be drastically
reduced if motor is not operating properly. Vanes can
break or be damaged if motor/pump runs in the wrong
direction.

OPERATION

WARNING

I

njury Hazard

Air stream from product may contain solid or liquid
material that can result in eye or skin damage.

W

ear hearing protection. Sound level from product

m

ay exceed 85 db(A).

Failure to follow these instructions can result in eye
injury or other serious injury.

Pump only clean dry air.
Do not pump flammable or explosive gases or use

i

n an atmosphere that contains such gases.

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.

C

heck that coupling guard and shroud are in place

before operating.

P

roduct surfaces may become hot during operating,

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.

Do not spray flammable or combustible liquid.

Check with a qualified electrician or serviceman if the
g

rounding 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.

It is your responsibility to operate this product at
recommended pressures or vacuum duties and room
ambient temperatures. Do Not start against a vacuum
or pressure load.

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.
T

he plug must be plugged into an outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.

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)
