INSTALLATION AND OPERATING MANUAL
This manual is written to cover L-Series Model vacuum pumps. The model number is stamped into the
nameplate.
The number will appear as follows: LXXX-GX.
Please identify the model number and serial number when ordering parts.
1.0 INSTALLATION
1.1 Unpacking

Inspect the box and pump carefully for any signs of damage incurred in transit. Since all pumps are ordinarily
shipped F.O.B. from our factory or regional warehouse, such damage is normally the responsibility of the
carrier and should be reported to them.
The vacuum pump is bolted to the skid with studs that are connected through the rubber feet of the
pump. Remove the nuts from the underside of the crate and remove the pump. Unscrew the studs
from the rubber feet.
The inlet and exhaust of the pump are covered with plastic caps to prevent dirt and other foreign
substances from entering the pump. Leave these caps in place until you are ready to pipe the pump
to your equipment.
1.2 Location
Install the pump in a horizontal position on a level surface so that the pump is evenly supported on its
rubber feet. Leave 12-18” of access around the pump to allow proper cooling. Also, adequate
ventilation must be provided for the fans, radiator, and motor.
Allow access to the oil sight glass in order to inspect the oil level, and the exhaust port for easy access
to change the exhaust filters.
Do not tip the pump over if filled with oil.
1.3 Power Requirements
A schematic diagram for the electrical motor terminal connections is located in the junction box of the
motor or on the motor nameplate.
The motor must be connected according to the electrical codes through a fused switch in order to protect the
motor against electrical or mechanical overload conditions. The overload of the motor starter must be set at
a level equal to the full load motor current listed on the motor nameplate.
If the pump is supplied with a motor starter, it is preset at the factory according to customer specifications.
It is advisable to check that these settings are in line with the voltage at your location. If the voltage is
different, please contact Airtech for motor and starter information.
Correct direction of rotation is marked by an arrow on the motor fan housing and is counterclockwise when
looking at the motor from the motor’s fan side.
After electrical connections have been made, but prior to filling with oil, the rotation of the motor should be
checked. If backward, reverse any two leads of the three at the power connection.
1.4 Vacuum Connections
Use a pipe size that is at least the size of the pump inlet connections. Smaller lines result in a reduced
pump capacity.
Pumps operating in parallel on a common main line should have a manual or automatic operated shut-off valve
or positive action check valve, installed in the suction line adjacent to the pump suction flange. The built-in anti-
suck back valve should not be used as a shut-off valve for the vacuum system.
Remove the plastic protective cap from the inlet port prior to connection of the pump to the system.
Should process gas contain dust or other foreign particles, a suitable in line (inlet) filter should be connected to
the inlet port. Consult Airtech Inc. for recommendations.
The vacuum piping should be designed to ensure that no liquids such as condensate or liquid carried over from
the process can reach the pump. If this possibility exists, a knock-out liquid separator should be installed.
Consult Airtech Inc. for recommendations.
If an exhaust manifold is connected, install a drip leg and drain near the pump exhaust to prevent exhaust
condensation from entering the exhaust box. The following thread sizes are standard on the Airtech pumps:

1.5 Oil Filling
The pump is shipped without oil. After level installation and correct rotation has been established, fill the pump
with recommended motor oil through the oil fill port. Oil level should be at the 3/4 position on the oil sight
glass.
Non-detergent oil should be used. Airtech recommends either ATO-1000 for normal duty operation or ATO2000
for severe duty operation. ATO oil is a high quality vacuum oil that will provide longer running time between oil
changes, better lubrication at high operating temperatures and prolongs the life of the exhaust filter elements.
Oil detergent additives can cause exhaust filters to become clogged and shorten their service life.
The following table gives the approximate quantities of oil required for each model.

Do not add fill oil with pump running or through the inlet or exhaust ports! Do not overfill.
2.0 OPERATION
2.1 Start-up
Check rotation of the motor as described in paragraph 1.3 …Power Requirements.
Fill the pump with oil as described in paragraph 1.5 …Oil Filling
Start the pump with the inlet closed. Run the pump for a few minutes and then shut down. Check the oil level
again and make sure the oil level is between the ¾ mark and full on the upper oil sight glass.
Add oil if necessary. Pump oil should only be added when the pump is off and circulating oil has sufficient time
to return to the oil sump.
2.2 Stopping the Pump

To stop the pump, turn off the power. A built in anti-suck back valve will prevent oil from the oil reservoir being
sucked back into the cylinder after the pump is shutdown.
Do not utilize the anti-suck back valve as a check valve. Consult Airtech Inc. for proper check valves.
2.3 Gas Ballast
L-Series pumps are equipped with a gas ballast. The gas ballast valve is located between the inlet port and the
exhaust box. Its main function is to prevent water vapor from condensing in the pump that causes
emulsification of the oil resulting in possible pump failure.
In applications involving a moderate quantity of water vapor, it is recommended to run the pump for 10 minutes
at normal operating temperature, prior to going on process. The pump should also be operated off process for
10 minutes prior to shut down. A slight air bleed (purge) is recommended during these 10-minute cycles to
prevent the vapor from condensing in the pump.
3.0 MAINTENANCE
L-Series vacuum pumps require very little maintenance. To ensure optimum performance, the following
maintenance steps should be followed:
3.1 Pump Oil
3.1.1 Oil Level
Under normal circumstances it should not be necessary to add oil between oil changes. A significant drop in oil
level means there is either an oil leak, a defective exhaust filter or O-ring, or a leaking anti-suck back valve. If
the pump is smoking excessively, the exhaust filter may be installed improperly.
It is normal for the oil to be foamy or lightly colored in an operating pump. This may be normal aeration of the
oil. If the oil appears milky or dark colored, it is contaminated or burned and must be changed.
Check the oil level only when the pump is shut off. Replenish oil if it drops below the ¼ mark of the top sight
glass. Oil must be added through the oil fill port only.
Caution: Do not add oil while the pump is running, since hot oil can escape from the oil fill port.
3.1.2 Oil Type and Quantity
See section 1.5 -Oil Filling -for details on oil type and quantity
3.1.3 Oil Change
When using ATO-1000 oil, it is recommended to change the oil every 500-750 operating hours.
When using ATO-2000 oil, it is recommended to change the oil ever 750-1000 operating hours.
Oil change frequency is dependent upon the application and ambient temperature. It is recommended that the
customer monitor the condition of the oil during this period.
3.1.4 Oil Spin-On Filter
Replace automotive-type spin on filter at every oil change.

3.2 Inline (Inlet) Filter
Check inline (inlet) filter on a weekly basis. The filter cartridge should be cleaned or replaced when dirty.
Consult Airtech Inc. for replacement element information.
Caution: Depending on the mounting position of the filter, be careful not to allow accumulated foreign material to
fall in the pump suction inlet when removing the filter cartridge. Horizontal filter installation is recommended to
prevent this.
3.3 Exhaust Filter
Replace these filters every 9 to 18 months of operation or as necessary. The service life of these filters varies
depending upon the application and frequency of oil change. It is necessary to change these filters only when
they become clogged. Indications of clogged filters are smoke or oil mist coming from the exhaust of the pump,
higher than normal motor current, and the exhaust pressure gauge reading of 3 psig or greater.
Do not clean or re-use these filters. Filters must be disposed of in a proper way as they might contain toxic
substances carried over from the process. Replace O-rings on filter when changing.
3.4 Maintenance Chart
See the motor manufacturer’s manual for the periodic motor maintenance.
Daily: visually check oil level and color.
Weekly: inspect inline (inlet) filter.
Every 2-6 months: drain and discard oil from pump while hot. Refill with fresh oil. Every
9-18 months: replace exhaust filter elements and O-ring.
The operating life of the pump is greatly enhanced based on the oil quality and condition of the filters.
Periodic maintenance will ensure a reliable operating vacuum pump.
3.5 Overhaul Kit and Accessories

An overhaul kit contains a set of gaskets, O-rings, vanes, bearing, bearing sleeves, shaft seals and taper
pins. Please consult Airtech Inc. parts department for information.
