D. SENSOR INSERTION/IMMERSION MOUNTING
TheSensor’smountingorientationmustprovideacontinuous
andadequatecirculationowtopreventthetrappingofair
bubbleswithintheSensor’selectrodearea(CS51shownin
gureII.D.1).Failuretodosowillresultinconditionsthatwill
prevent the Sensor from functioning properly.
1. INSERTION MODE (in-line installation)
Use approved sealant, i.e. Teon tape as required.
 1. VerifythattheSensor’sFittingassemblyisproperly
  assembledasshowningureII.D.1.
 2. InserttheSensorFittingassemblyintothe“T”tting
  withelectrodealignedasshowningureII.D.1.and
tightly secure.
2. IMMERSION OR DIP SENSOR ASSEMBLY
Use approved sealant, i.e. Teon tape as required.
 1. VerifythattheSensor’sFittingassemblyisproperly
  assembledasshowningureII.D.2.
 2. InsertandpulltheSensor’scablethroughthe 
extension tube and then tightly attach extension tube to
  SensorassemblyasshowningureII.D.2.
E. ELECTRICAL INSTALLATION
The electrical installation procedures provided in this manual are
common to all Conductivity & Resistivity Monitor/controllers. See
gureII.B.1.fortheholedimensionsoftheenclosure’scable
accessholes.Unlessotherwiseinstructed,refertogureII.E.1.
for the 750 Series IIMonitor’sterminalblockconnectorwiring
designations.
NOTE:Afterremovinganenclosure’saccessholecutout,itis
suggestedthattheusermountawatertightrestraintxtureprior
to installing a cable.
A device to disconnect the Model 750II from the power
supply is required. It is recommended that this switch or
circuit breaker be labeled as the disconnection device for
the Model 750II.
1. MAIN INPUT POWER INSTALLATION
WARNING: All AC line powered Monitor/controllers are
factory set for 115 VAC. Before starting, ensure the input
power “115/230” selection is correct for your requirements.
Failure to do so is beyond the responsibility of the Myron L
®
Company. See section II.E.2. below and gure II.E.1.
NOTE: Some models may have either a 24 VAC or a 24 VDC
input power requirement - check labels carefully.
For OEM models skip to step #7.
 1. VerifythatthemainACpowersourceisturned“OFF”
or disconnected.
2. Using a standard slot screwdriver remove the four (4)
screws on the front panel.
3. Carefully wiggle the front panel to loosen and pull
gently toward you. Do not pull more than about
8 inches/20CM or you could damage the wiring
harness.
