Introduction
The Millipore high output vacuum/pressure pump is a continuously-running constant air-ow type unit for use with laboratory equipment. This vacuum/
pressure pump combines the quietness and durability of a diaphragm pump with the performance of a piston-type pump. It compresses air by means of
a motor-driven piston. This pump is intended for ltration of liquids or for other continuous or intermittent uses, with all types of lter holders, multi-well
devices, manifolds, and other laboratory equipment.
CAUTION: Always use the supplied hydrophobic vent lter or a vacuum-ask water trap in conjunction with the pump, as indicated in Figures 1 and 2.
Never pump or draw liquids through the pump, as this will damage the pump.
The pump has these features:
The motor and pump are permanently lubricated.■
A thermal overload switch with automatic reset protects the motor.■
Low operating noise is further minimized by rubber feet.■
A Millex■®-FA50 hydrophobic vent lter and 27 in. (69 cm) of 1/4 in. (6 mm) I.D. vacuum tubing are supplied with the pump.

Rules for Safe Operation
The motor is thermally protected and will automatically restart unexpectedly when the overload device resets.
Do NOT pump ammable or explosive gases or vapors or operate this pump in an atmosphere containing ammable
or explosive gases or vapors.
Use of this pump in a manner not specically stated in this user guide may result in severe bodily injury.
Read and understand the information in this owner’s manual before operating the vacuum/pressure pump.
■ The vacuum/pressure pump should be operated in a dry, clean, and well ventilated area.
■ When the unit is not in use, wrap the power cord around the vacuum/pressure pump and store in a dry place. Do not abuse the cord.
■ Replace the Millex-FA50 vent lter (SLFA 050 10) if necessary.
■ Inspect hose, plug, and cord for signs of damage before use. Do not use if a deciency is found. Never operate a damaged unit. Contact Millipore for
replacement parts; see Technical Assistance section for details.
■ This vacuum/pressure pump needs no lubrication. Applying oil to any part may result in polluted air delivery to the air-handling equipment and will
damage the pump.
■ To operate at maximum efciency, the pump system must be thoroughly clean. Refer to the Maintenance section for details on properly cleaning the
pump.
■ Compressed air blast must never be aimed at anyone because it can cause serious injury. Keep children away.
■ All vacuum/pressure pumps generate heat, even under normal operating conditions. To avoid serious burns, never touch the head parts or tubing during
and immediately after operation.
■ When ltering acids, bases, or organic vapors or gases, use the Millipore Chemical Duty Vacuum/Pressure Pump (WP61 115 60, WP61 220 50,
WP61 100 60).

Usage Guidelines
■ Always use the Millex-FA50 vent lter and 1/4 inch silicone tubing
included with the pump when applying vacuum. This will prevent
liquids or vapors from entering the pump. A properly attached
Millex-FA50 vent lter is illustrated in Figure 1.
■ For maximum protection of the pump, use the Millex-FA50 vent lter
AND a vacuum trap to protect the pump from vapors and gases. The
vacuum trap consists of a 1 liter ltering ask (Millipore cat. no.
XX10 047 05), No. 8 stopper (XX10 047 08) and silicone tubing.
Additional tubing is available as Millipore cat. no. XX71 000 04. This
assembly is illustrated in Figure 2.
■ Never pump or draw liquids through the pump. This will damage the
pump. The lter ask and vacuum trap should be emptied after each
use.

High Output Vacuum/Pressure Pump 5
The Millipore Vacuum/Pressure Pump is shipped ready for use. See the
Specications section for required operating conditions.
CAUTION: The pump is rated for indoor use only.
CAUTION: Be sure available power matches unit requirements. A
grounded three-conductor AC electrical source is required.
Units are available for 115 VAC 60 Hz, 100 VAC 50/60
Hz, or 230 VAC 50 Hz. See the Specications section for
details of electrical supply options available.
1. Unpack the unit and retain all packing material until you verify proper
product operation.
2. The unit rests on four vibration isolator pads. Place the unit on a suit-
able surface, such as a bench, desk, or table. Be sure not to block
the ventilation holes located on the motor housing.
3. Select appropriately-sized tubing, according to your application. Use
approximately 1/4 in. I.D. tubing to withstand the anticipated pressure
or vacuum.
CAUTION: During vacuum ltration, use the supplied Millex-FA50
hydrophobic vent lter, to prevent excessive amounts
of liquids or mist from entering the pump (gure 1). For
maximum protection, use a vacuum-ask water trap
(gure 2).
4. Prepare the necessary equipment or lter holder and connect the
tubing to the equipment. Do not connect the tubing to the pump.
5. Plug the power cord into an appropriate electrical source.
CAUTION: Do not turn the pump on with equipment or lter holder
already attached.
If the pump is inadvertently turned on with the tubing fully connected
and it does not run, turn off the pump and disconnect the tubing.
Restart the pump and then reconnect the tubing. If the pump’s
thermal overload switch automatically shuts off the motor, disconnect
the tubing and allow the pump to cool for at least 10 minutes before
restarting. Reconnect the tubing only after the pump is operating.
6. Turn on the pump, using the toggle switch located at the rear of the
pump.
7. Connect the tubing from the lter holder or other equipment to the
pump and begin your procedure.
8. If using the pump for vacuum: Adjust the vacuum by closing the
pressure regulator and opening the vacuum regulator fully (counter-
clockwise). Slowly tighten down (clockwise) the vacuum regulator
until you obtain the desired vacuum reading on the vacuum gauge.
If using the pump for pressure: Adjust the pressure by turning the
vacuum regulator down fully and opening the pressure fully (counter-
clockwise). Slowly tighten down (clockwise) the pressure regulator
until you obtain the desired pressure reading on the pressure gauge.
9. Turn off the pump when you are nished. Disconnect the tubing rst
from the pump and then from the lter holder or other equipment.

Maintenance
Under normal operating conditions, and using proper handling
procedures, the high-output vacuum/pressure pump should provide
many hours of trouble-free operation.
Millipore dry vacuum/pressure pumps are 100% oil-free. The pump
employs a non-lube piston and cylinder. No maintenance is
necessary for the bearings. All bearings are sealed and permanently
lubricated. Lubrication should not be attempted. The units are built for
continuous duty operation with quietness and durability.
CAUTION: Do not lubricate any of the parts with oil, grease, or
petroleum products. Do not clean with acids, caustics, or
chlorinated solvents. Do not replace the connecting rod or
motor bearings.
Troubleshooting
Vacuum Problems
Leakage, contamination, and unusual out-gassing are the general
causes of problems associated with poor vacuum. To operate at
maximum efciency, a system must be thoroughly clean. If the system is
completely clean and free from leaks, and unwarranted vacuum
problems still exist, the pump should be checked. A simple criterion for
the condition of the pump is the determination of its maximum vacuum
capability. This can be accomplished by blocking the intake and reading
the vacuum level on the gauge.
Pressure Problems
Leakage and contamination are the general causes of problems
associated with poor pressure. To operate at maximum efciency, a
system must be thoroughly clean. If the system is completely clean
and free from leaks, and unwarranted pressure problems still exist, the
pump/compressor should be checked by a service technician.
