QED MicroPurge basics MP10UH Instruction Manual page 9

Introduction/Quick Start
Quick Start: Connect the pump air supply hose to the fitting label-edAIR OUT on the
MP10UH. Connect the black air supply hose to a compressed air or gas source and
connect it to the fitting labeled AIR IN on the MP10UH. Supply up to 300 psi compressed
air or gas to the controllerurn the controller throttle until the gauge reads appropriate
pressure for the depth of the sample pump approximately, 0.42 psi per foot of pump depth.
Follow instructions on the battery panel:
Opening the MP10UH case turns power on.
Note: It may take up to 20 seconds for the unit to power up.
For pump depths greater than 250 ft
MODE
Select manual mode (MN) with key
Turn throttle to set pressure on gauge to 12-16 psi higher than the minimum requirement
of 0.5 psi per foot of pump depth location in the well.
Then set Refill and Discharge times as needed to begin and optimize pumping; use initial
settings of 30 seconds each for both refill and discharge for pump depths to 300 ft; for
pump depths over 300 ft., use 60 seconds each for both refill and discharge.
Press Cycle to START pumping.
When water discharge begins, adjust throttle until a slow, steady flowstream is achieved.
Then adjust refill and discharge times to achieve desired flow rate. To collect samples,
I I
continue purge flow, or use key to directly control sample flow and pause.
For pumps located at depths less than 250 ft.
MODE
Select MicroPurge mode (MP) with key
Turn throttle to set pressure on gauge to 4-8 psi higher than the minimum requirement of
0.5 psi per foot of pump depth location in the well.
Select desired Cycles Per Minute (CPM) with (default value is 4 CPM, lower CPM
for deeper wells, higher CPM possible with shallow wells).
Press keys to set the desired purge flow rate.

To collect samples, continue purge flow, or use key to directly
control sample flow and pause.
