pump, is located on the front of the electronics enclosure. The refrigerator has its own individual
power cord. By using the AC/DC converter the user does not have to be concerned with replacement
of batteries, charging of batteries, or any other factors which affect 12 VDC systems. The system has
been thoroughly tested using 115 VAC and will provide o utstanding service, reliability, and longevity.
To power the unit up follow these simple steps:
1. Check to make sure that the pump cover is
securely fastened to the pump housing and that
the unit is ready to be powered up.
2. Locate the power plug coming out of the
electronics enclosure.
3. Plug the AC/DC converter into the appropriate
receptacle.
4. Turn the power switch, located on the right side
of the electronics enclosure, to "ON". Verify, by
looking at the display, t hat power is being
applied to the system. If the display does not light up, confirm that the appropriate
connections have been made. I f the unit does still not power up, call the Manning Service
Department. T hey will be able to provide assistance in getting t he unit o perational.
WARNING: Hard-wiring should only be done by a certified electrician.
Sample Intake Line
Attach the intake hose to the connector at the end of the pump tubing.
Intake Hose Placement
Place the intake hose strainer directly in the channel flow, not in an eddy or at the edge of the flow.
In channels with debris, provide deflection to prevent clogging of strainer holes. The weight supplied
with the intake hose is usually sufficient to prevent the intake from being pulled to the surface of a
fast channel.
The correct vertical position of the strainer depends on the type of sample being taken. Placing the
strainer at the bottom o f t he flow results in a heavier concentration o f solids in the sample, while
placing the strainer at or near the top of the flow results in heavier concentration of oils, fats, and
other floating or suspended contaminants.
The intake hose should be positioned so the hose can drain between sample cycles and no low spots
exist which would trap water. The correct and incorrect hose placements are shown below.
