Tops .003”
End : .002”

Product Use Criteria:

• Pump only clean, dry air.

• Operate at 32ºF - 104ºF (0ºC - 40ºC).

• Protect unit from dirt & moisture.

• Do not pump flammable or explosive gases or
use in an atmosphere that contains such gases.

• Protect all surrounding items from exhaust air. This
exhaust air can become very hot.

• Corrosive gases and particulate material will
damage unit. Water vapor, oil-based contaminants
or other liquids must be filtered out.

• Consult your Gast Distributor before using at high

altitudes.

• Vane Life: 5,000-15,000 hours depending
upon application

• Model numbers ending in “X” have automatic thermal

protectors which protect the motor by shutting the motor

off if it overheats. The motor will automatically restart
once the motor has cooled.

• Oil-Less rotary-vanes require NO lubrication.

• Sealed bearings are grease packed.

• Use of petroleum or hydrocarbon products will

reduce carbon-vane service life.

Your safety and the safety of others

is extremely important.

Correct installation is your responsibility. Make sure

you have the proper installation conditions and that

nstallation clearances do not block air flow.

i

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:

DANGER

You will
follow instructions.

be killed or seriously injured if you don’t

WARNING

You can
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.

INSTALL ATION

be killed or seriously injured if you don’t

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

nd using shock mounts will reduce noise and vibration.

a

Plumbing

Remove plugs from the IN and OUT ports. Connect

ith pipe and fittings that are the same size or larger

w
than the product’s threaded ports.

Accessories

The product’s intake and exhaust filters will provide
adequate filtration in most applications. Consult your
Gast representative for additional filter
recommendations. Install relief valves and gauges at
inlet or outlet, or both, to monitor performance. Check
valves are 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.

Electrical Shock Hazard

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.

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 attached to the product provides
required electrical information. Check that power
source is correct to properly operate the dual-voltage
motor.

OPERATI ON

Injury Hazard

Product surfaces become very hot during
operation,
allow product surfaces to cool before handling.

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

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

2

It is your responsibility to operate this product at
recommended pressures or vacuum duties and
room ambient temperatures.

Model numbers ending in “X” have automatic
thermal protectors which protect the motor by
shutting the motor off if it overheats. The motor will
automatically restart once the motor has cooled.

Start Up

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. 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.

MAINTENANCE

General Maintenance

1. Remove end cap and filters. Inspect filters for

rips,tears, cuts, brittleness and excessive foreign
material.

2. Clean filters if in good condition with
ompressed air. Re-inspect for wear conditions.

c
Set filters aside.

3. Check filter/muffler (#11) for compacted debris. If

debris is present, replace filter/muffler.

. Check condition of O-ring. It should be soft and

4

flexible. Replace if it is not.

5. Remove and inspect muffler box. Clean box. Set

box aside. (Not all models have a muffler box.)

. Check gasket for cracks or tears. Install new

6

gasket
if any cracks or tears appear. Replace gasket.

7. Replace muffler box.

8. Reinstall filters or install new filters if required.

Reinstall end cap.

Flushing

Flushing this product to remove excessive dirt, foreign
particles, moisture or oil that occurs in the operating
environment will help to maintain proper vane
performance. There are 2 options for this operation.
If Option 1 does not remedy your problem, go on to
Option 2.

Electrical Shock Hazard

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

If product is hard wired into system, disconnect
electrical power at the circuit breaker or fuse
box
before performing maintenance on this product.

Failure to follow these instructions can result in
death, fire or electrical shock.

Injury Hazard

Product surfaces become very hot during
operation,
allow product surfaces to cool before handling.

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

Flush this product in a well ventilated area.

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

Use only Gast recommended flushing solvent or
other non-petroleum based flushing solvent. Do
Not use kerosene or ANY other combustible
solvents to flush product.

Option 1

You will need 2 pipe nipples at least 4 inches long with
1/4” NPT for 0323 and 0523 products, or 3/8” NPT on
one end for 0823 and 1023 products. No nipples are
needed if the unit does not have a muffler box.

1. Remove filter and muffler cap (#9).

2. Remove 5 bolts. Use a small hammer to tap on

muffler box to remove it. Attach pipe nipples
where muffler caps were removed.

3. Start product and add flushing solvent to the inlet

port. If using liquid solvent, pour several
tablespoons directly into the inlet port. If using Gast
recommended spray solvent, spray for 5-10
seconds into inlet port. Place towel over exhaust

to clean up solvent.

4. Plug inlet port for 20-30 seconds. Listen for

changes in the sound of the pump. If pump sounds
smooth, go to next step. If pump does not sound
ike it is running smoothly, installing a Service Kit
will be required (See Service).

5. Release vacuum.

6. Repeat steps 3-5 three or four times.
