WARNING

DANGER

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 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.

DIAGRAM A

Moisture Trap

Liquid or moisture vapor will damage the pump. Install a
moisture trap if liquids could be drawn into the pump. For
the correct type and size, contact your local Distributor or
the factory.

Plumbing

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

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.

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.

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.

OPERATION

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. Be sure the three phase motor turns in the proper
direction of rotation after installation. Turning in the
wrong direction will drastically reduce vane life.

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.

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.

MAINTENANCE

3

It is your responsibility to:

• Regularly inspect and make necessary repairs to
product in order to maintain proper operation.

• Make sure that pressure and vacuum is released

from product before starting maintenance.

Check intake and exhaust filters after first 500 hours of
operation. Clean filters and determine how frequently
filters should be checked during future operation. This

one procedure will help to assure the productʼs
performance and service life.

Check that all external accessories such as relief valves
and gauges are attached to cover and are not damaged
before re-operating product.

SHUTDOWN PROCEDURES

It is your responsibility to follow proper shutdown
procedures to prevent product damage.

Failure to do so may result in premature pump failure.
The Gast Manufacturing lubricated Vacuum Pumps and
Compressors are constructed of ferrous metals or
aluminum which are subject to rust and corrosion when
pumping condensable vapors such as water. Follow the
steps below to assure correct storage and shutdown
between operating periods

1. Disconnect plumbing.

2. Operate product for at least 5 minutes without
plumbing.

3. Cover inlet port (vacuum side) and run pump for 1-3

minutes. Shut the pump down under vacuum.

4. This unit requires lubrication. Refill oil reservoir to
proper level before storage.

5. Be sure to plug open ports so dirt and other
contaminants do not enter the unit. It is now ready
for shutdown.

Clean filters when necessary by removing and washing
in a solvent or soap and water. After cleaning, dry with
compressed air to make sure all moisture is removed
before replacing filters.

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. If your pump is not getting the vacuum or
pressure level expected, flushing is required. Vanes will
stick when dirty and may cause pump to be noisy or
inefficient.

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

1. Disconnect electrical power supply.

2. Release all pressure and vacuum from pump.

3. Remove all accessories at the inlet and exhaust
ports.

4. Remove filter.

5. Start product. Place towel over exhaust port to
