• Damage to the sensor cable will result in electric shock, fire, physical injury, and / or death.
• Before installing the cable, verify that the power is OFF. If not, it will result in electric shock, physi-
cal injury, and / or death.
1. Choose a route for the cable (use the 39 foot [12 m] cable included with the sensor well) from
the sensor well to the Hydro Kit PCB so that the cable is protected from damage, foot traffic, and
extreme weather and temperature conditions.
2. Loosely secure the sensor well cable about every three (3) feet with cable ties. To avoid damag-
ing the sensor well cable,
do not pull the ties too tight.

3. Route the sensor well cable through the Hydro Kit frame and into the control panel area. If the
cable will pass through an access hole with sharp edges, install field-supplied protective grom-
mets to avoid damaging the cable.
4. Find the red CN-TH4 connector on the Hydro Kit PCB. Inspect the leads and pins of the sen-
sor well cable plug, looking for bent pins and loose connections between the wire leads and the
metal pins. If not damaged, insert the sensor cable plug into CN-TH4.
