High Output Vacuum/Pressure Pump 5
The Millipore Vacuum/Pressure Pump is shipped ready for use. See the
Specications 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 Specications 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.
