Introduction / Quick Start
Introduction: The MP50 Micro Purge Basics Controller/Compressor is used to operate QED
Well Wizard™ bladder sampling pumps to purge and sample ground water. The MP50 has
specific design features to make MicroPurge ™ sampling easier. These features include:
MicroPurge Mode Operation Simple Increase / Decrease keys allow you to easily set
the flow rate you need for each well.
ID Time Set Mode Operation Quickly recalls pre-determined settings for each well by
specifying a 3-digit ID.
Level Delay Interface The controller plugs into the optional MP30 MicroPurge Draw-
down / Water Level Meter to provide direct feedback of well drawdown and to pause
pump operation until the level recovers.
The optional MP30 MicroPurge Drawdown / Water Level Meter plugs into the MP50 to pro-
vide water level feedback. The MP30 uses a standard conductivity probe to detect the
ground water surface and a marked tape allowing the user to measure the depth. When the
meter is set in MicroPurge mode, the probe is lowered a specific distance below the static
water level and fixed in this position. During well sampling if the water level drops below
the user-set probe position, the MP50 is paused which prevents further drawdown by the
pump. Once the level recovers the MP50 begins pump operation again, starting in the pump
refill cycle. Use of the MP50 with the MP30 is detailed later in this manual.
Insert Batteries: Remove the battery cover on the top of the MP50. Insert 3, AA alkaline bat-
teries into the battery holder and carefully replace the holder in the carrier. Replace the
battery cover and tighten the 4 screws. Batteries should last for about 6-8 weeks of typical
full-time field use. If the MP50 will be stored longer than about 3 months, the alkaline batteries
should be removed to prevent leakage.
