OMEGAENGINEERING,sothatthe levelswitchmaybemovedtodifferentlocationsonthetankbyslidingit

intootherbrackets.

Attachthebrackettothetank:

1. DeterminewhetherthetankisPPorPE.Theslide‐infittingshippedwiththesensorisdeterminedby

the part number. If necessary, obtain an additional

bracket.

2. Determinethemountinglocationforthelevelswitch.The

point of actuation (where the sensor will send a “wet”

signal)ismostoftenatthecenterofthesensor;however

theactual Point ofActuation (POA) maydiffer depending

on the application liquid and tank wall characteristics.

After positioning the fitting to check clearances, etc.,

remove the paper protective strips from the adhesive of

thebracket.

3. Pressthebracketintoplace.Theadhesiveprovidesaseal

between the sensor and the tank wall, and will hold it in

place during testing and installation.If desired, the sensor may be installed temporarily without

welding the fitting to the wall.If several different locations must  be tried before permanent

installation,usedouble‐sidedfoamsticktapedesignedforPPorPE.

4. AfterthesensorhasbeentestedtoverifythePOA,weld,glassorstrapthebrackettothetankusing

standardindustrialplastictechniques.

Special note for small round tanks:The bracket may be attached to small, round tanks, as

long as the

majorityofthe bracketisfirmlyattachedtothewall.Howe ver,extremeinstallationsmayaffecttheswitches

performance.

Mountthesensorinthebracket:

1. Slidethesensorintothebracket.

2. Aftertrimming the sensorwire to length if needed by theinstallation, threadthe sensor wire intoa

plasticflexibleconduitwitha1/2"malefitting.Screwtheconduitintothesensor,beingcarefulnotto

cross the threads.Donot over tighten the conduitin the sensor as thismay break the fitting.Such

damage is not covered by the warranty.Take care while pulling

the wire through conduit that no

excessive tension is placed on the sensor end of the wire, so that the wire is not broken from the

sensorhousing.

3. Connectthe sensor wire to the controller following the instructions in its manual. See the following
