Measurement Ranges and Calibration

Compensated temperature range:
0–50 °C
Precision at room temperature (% MR)
+ 0.25
Resolution

If a pressure can not be displayed, the message OFL (Overflow) or UFL
(Underflow) will appear on the gauge screen. If a pressure outside the
measurement range of the vacuum gauge is applied, the last pressure
value is displayed blinking. In both of these cases, recalibrate the
pump or check tubing connections. If problems continue, contact Milli-
pore Technical Service.
Pump the Sample
When the digital vacuum gauge is set to the appropriate values, begin
pumping by turning on the on/off switch on the front of the pump.
When pumping is complete, turn off the unit using the on/off switch.
To reduce vacuum flow without using the digital vacuum gauge, turn
the regulator knob counter-clockwise to the open position.
Maintenance
Under normal operating conditions, and using proper handling proce-
dures, the Millivac Maxi Pump should provide many hours of trouble-
free operation. These durable units are built for quiet continuous duty
operation. Millivac Maxi 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.
CAUTION:
Do not lubricate any of the parts with oil, grease or petro-
leum products. Do not clean with acids, caustics or chlori-
nated solvents. Do not replace the connecting rod or mo-
tor bearings.
Use mild soap or standard laboratory detergent, bleach, or ethyl alco-
hol to clean all surfaces of the Millivac Maxi Pump. After cleaning,
rinse off any residue with a soft cloth or paper towel dampened in
clean water, then wipe dry. You can also use radioactive decontamina-
tion solutions and sprays.
NOTE:
Do not autoclave the Millivac Maxi Pump.
