Maintenance
This pump comes equipped with an exhaust lter located on the inside tray of this unit. It is recommended to replace this lter every 3 months or if a loss of performance of the pump is observed. Your
lters may last longer or need to be changed more frequently depending on the amount of use the
pump gets and the environments it is exposed to. Replacement lters may be ordered from Zefon or
a Zefon distributor under product #03879.
Proper care and maintenance of your pump is essential for a long useful life. Rough and abusive use
and/or accidental impacts may damage the unit. Zefon recommends periodically wiping down the unit
with a clean dry cloth to keep it free of dirt and debris along with regular inspections of the AC power
supply and cords to ensure it is not damaged and posing an elecrical hazard.

Setting Up the Pump for Sampling
1. Remove the sampling stand from the inside tray and screw into the top of the lid.
Adjust to the desired height.
2. Connect the tubing to the pump at the Quick Disconnect port on the pump. Attached the other
end to the top of the sampling stand.
3. Turn the pump power switch on.
4. Use the Up/Down Arrows to set the desired sampling time.
5. Press the START/STOP button to start the pump. (do not attach any lter media during this step)
6. Adjust the ow using the knob on the ow meter to the desired ow.
7. Once the ow rate is set, Press the START/STOP button to stop the pump.
8. Press and hold the START/STOP button for 3 or more seconds to reset the timer to the original
sampling time.
Taking a Sample
1. Turn the pump power switch to the ON position if it is not already on.
2. Use the Up/Down Arrows to set the desired sampling time.
3. Press the START/STOP button to begin sampling.
4. When the sample is nished, the pump will beep and the timer will reset itself to the time that
was originally set.
Charging the pump
1. When the pump battery level has dropped to a level where the pump cannot operate with
sufcient voltage to maintain ow at a sufcient ow level, the Low Battery light will illuminate.
2. To charge the battery, use the supplied AC power adapter. The POWER light on the charger
will illuminate RED and a solid GREEN light indicates the current charge capacity.
3. If the pump battery has become fully discharged, the charger will default into trickle charge
mode for the rst couple of hours until the battery has stabilized with a minimum charge level
that will safely allow fast charging.
4. Once the battery is fully charged and operating in trickle charge mode (100% light will be
solid), it is safe to leave the pump connected long term to keep in top condition or to unplug
and begin to use. The pump may optionally be used while connected to the charger to run on
AC power.

Flow Rate Accuracy
Flow meters like the one installed on this pump are considered ‘secondary’
standards for measuring ow. It is recommended that the accuracy of this owme-
ter is periodically veried against a primary ow standard such as a bubble meter
or dry calibrator.
