Background
MP 30 Operating Instructions
The MP30 Drawdown Control Meter is designed to help control draw-down during monitoring
well purging, especially when used with MicroPurgebasics pump controllers. The MP30 has
3 primary modes of use:
1. When connected to MicroPurge basics controllers, pump operation is automatically
paused if the selected drawdown limit is reached, then resumed when the well recovers
to this point.
2. The MP30 includes light and sound indicators of reaching the drawdown limit (dry probe
condition); these function independently of the MicroPurgebasics controllers, and may
also be used in this way with controllers other than Micropurge basics models.
3. When switched to water level mode, the MP30 provides conventional water level meter
functions of light and sound indication upon contact of the probe with water.
Drawdown Control Quick Guide
1. Determine static water level in conventional manner, with MP30 power
switched "ON" and Drawdown Control switched to "OFF" (see Figure 1).
2. When well purging is to begin, switch the MP30 Drawdown Control switch
to "ON" and lower the probe to desired drawdown control level.
3. Connect the MP30 to the MicroPurge basics controller with the cable
provided.
4. Begin purging; the MP30 will automatically signal the controller to pause
pumping if the probe is no longer submerged, and will also activate the
buzzer and the "Level Shutoff" light.
5. If the water level in the well recovers and reaches the probe, the basics
controller will resume pump operation and the MP30 "Probe Submerged"
light will activate.

OPERATION
Drawdown Control Quick Guide
6. If the drawdown level exceeds the selected drawdown limit point too
consistently, the flow purge flow rate can be further decreased with
adjustment of the controller, typically through one or more presses of
the flow "down arrow" key. If the flow rate is already at or near a
minimum desired rate, in some cases it may be also possible to lower
the probe to a new, lower drawdown control point to increase the well
recovery rate. Consult regulatory considerations before adjusting
protocols.

MP30 Cable connection
1. Cable connects to identical ports on MP30 and basics controllers, labeled "Control Port".
2. Connect cable to MP30 after reel has been turned to lower probe to desired drawdown
control point, to avoid twisting cable while tape reel turns.

Drawdown Control Point Selection
The Drawdown Control probe can be positioned using one of several different approaches.
First, it can be lowered directly to the point of maximum desirable drawdown. Secondly, it can
be lowered just part of the distance to the maximum drawdown point, for quicker feedback of
the response between purge flow rate and drawdown. For example, if 10 inches of maximum
drawdown is desired, the probe could be initial-ly lowered to just 5" or less below the static
water level. Then, if purgeflow exceeds well recovery, a quicker response indication of this
imbalance will be signaled than in waiting for the whole 10" to be drawn down, and purge flow
can be reduced sooner to achieve equilibrium of purge flow with well recovery.
Drawdown Control Response with MicroPurge basics controllers
Refer to the manual for the Micropurge basics controller for detailed information. In general,
when the Drawdown Control mode is switched "ON" and the probe becomes dry, the controller
display will indicate "LVL" in the upper left-hand corner of the controller display, and the con-
troller will pause pump operation until the probe again becomes submerged.When the probe is
again submerged, the basics controller will eliminate the "LVL" display, count down through the
current pump refill time setting, then resume pump operation with the currently set values.
MP30 Auto Shut Off
The MP30 has an automatic shut off feature. This feature is to conservebattery power should
the unit be left on when not in use. If the probe isno longer submerged and it takes more than
10 minutes for the water level to recover such that the probe is submerged again, the MP30
willshut off.The unit will need to be turned back on again. In some cases the drawdown point in
the well may be lowered to compensate for slowwell recovery. Consult regulatory consider-
ations before adjusting any purge protocols.

Equipment Check
General Information on MP30 Features and Usage
Well Hanger
1. Check equipment and battery by pressing the "ON" button. The unit should sound if the
speaker switch is not switched off. Also, the "LEVEL SHUT OFF" light should be on if the
probe is dry and the "DRAWDOWN CONTROL" switch is in the "ON" position. If the unit
does not respond, make sure the panel securing knobs are tight (see figure 1). If the unit
still does not respond, replace the 9 volt battery, reached by removing the securing knobs
and panel.
2. Test tape and probe by shorting out the center conductor and probe body on the pin on the
back axle of the unit while touching the white band on the probe with a moistened finger, or
lower the probe into a container of water.The buzzer and light should activate, in the "DRAW-
DOWN CONTROL" OFF " mode. If not, adjust the sensitivity and repeat.
3. Do not use distilled or deionized water to test the probe response.

GENERAL INFORMATION
General
Use in the Field- Static Water Level Measurement
Cleaning the Meter
1. Reel the tape down the well carefully, with the "DRAWDOWN CONTROL" switched
"OFF", avoiding the edge of the casing. Hang the unit on the casing with the provided
triangular wire bracket where possible and run the tape over the frame leg to avoid cuts
and nicks.
2. When the unit sounds, carefully measure the depth to water from your reference point by
slowly lowering and raising the probe to the air/water interface. Raise the probe, shake off
the water and repeat the measurement. In wells with cascading water, reduce the sensitivity
by turning down the sensitivity knob (counter-clockwise) to minimize false readings.
1. Always clean the meter after field use to maintain performance and minimize contamination
carryover.
2. Unwind the tape and wash with mild detergent, then rinse well and rewind. The following
cleaning agents are acceptable: 10% Alconox, Joy or Lestoil; methyl, isopropyl and isobutyl
alcohols; hexane and heptane. Rinse thoroughly with water afterwards.
3. Wash reel if necessary. The central electronic panel can be removed and the reel washed
down. Unthread the securing knobs, disconnect the two wire connectors and remove the
control panel. The reel can be cleaned with Alconox,Windex, Fantastic, Joy, alcohols,
hexane, heptane and mineral spirits. Rinse well with water and let dry before putting the
panel back in.Do not use abrasives or harsh solvents to clean the reel.
1. Avoid sharp edged casing.
2. Avoid entanglement with other equipment in wells or boreholes.
3. Do not use to plumb borehole depths.
4. Do not use as guide to backfilling with sand, etc.- probe may get locked in sand.
5. Rewind tape onto reel after each use.
Warranty is conditional on these guidelines being adhered to.

TROUBLESHOOTING
Troubleshooting
No sound when unit is turned on.
1. Check Battery and circuit board by following Step 1 of Equipment Check, above. Replace
battery if low and make sure wire connections of panel are tight.
2. Repeat Step 2 of Equipment Check, above. Check probe conductor to make sure it is clean
and not encrusted with mineral deposits. Check tape/probe connection and tape for any
breaks.
Continuous sound when unit is turned on or removed from water.
1. Make sure MP30 has "Drawdown Control" switched to "OFF" position.
2. Make sure probe conductor tip is clean.
3. Check for excess moisture on the back of the electronic panel and wire connector area.
4. Check probe/tape connection and tape for any breaks or leaks where water might get in.
