Installation
DISCONNECT ALL POWER SOURCES WHEN INSTALLING OR SERVICING THIS PRODUCT. FAILURE TO
TURN OFF ALL POWER SOURCES COULD RESULT IN SERIOUS INJURY OR DEATH.
Installing Float Switch Cable
STEP 1: REMOVE SCREWS
Remove the two screws from the front of the cable weight by
unscrewing until they release from the screw holes (1A) and pull
directly away (1B).
STEP 2: TETHER LENGTH
Determine the desired activation level, place oat switch cable
in the cable slot on the bottom half of the cable weight while the
top half is removed, and tether oat switch to the appropriate
length. Refer to the instructions that came with the oat switch
for recommended tether length guides to determine activation
or pumping range.
Note*: When installing the cable weight, make sure the narrow
end is facing up to ensure proper operation of the oat switch
and prevent debris from collecting on the cable weight.
Control Switches (Narrow Angle)
Minimum recommended tether length is 6 inches
Pump Switches (Wide Angle)
Minimum recommended tether length is 6 inches

Installing Float Switch Cable (continued)
STEP 3: SECURE FLOAT SWITCH CABLE
To secure oat switch cable to the cable weight, place the top half of the cable weight over the oat switch cable and align the
screw holes to the bottom half of the cable weight (3A). Tighten the two screws so both halves of the cable weight are snug
against the cable (3B). Perform a pull test, if the oat switch cable slips, tighten the screws until securely fastened to prevent
slipping of the cable, this will maintain an accurate activation level (control switches) or pumping range (pump switches).
