Sampling Pump; Infrared Source - PP Systems WMA-5 Operation Manual

Sampling Pump

The sampling pump used in the WMA-5 is a vibrating diaphragm type pump. It operates from 12 VAC
that is generated onboard from the WMA-5 12V DC power supply. It is capable of delivering flow rates up
to 500 cc/min flow. History has shown that this style pump is extremely rugged and durable and should
last for many years. If replacement is necessary, please contact PP Systems.

Infrared Source

The infrared source should last for many years and not require replacement. The obvious sign of failure
is that it is not flashing when the system is powered. It is preferable to return the instrument to PP
Systems for full factory recalibration after changing a failed source lamp. However, if that is not possible,
a few checks can be made to insure that the analyzer is working properly after changing a source lamp in
the field. Please contact PP Systems for more information.
