Ensure that the o-ring is seated properly on

Insert the sensor and turn clockwise. Tighten
carefully with a wrench. The sensor must be
screwed in tightly to ensure a watertight seal.
4) Replace the LOK-CAP. Leave in its open
position. Return the unit to the pool.
Any water inside the sensor housing will seriously impact
the system performance, accuracy and reliability.
