Probe Connections; Ph Probe; Orp Probe - Davey DPLGEU Mode D'emploi

• Carefully slide the probe locking nut, then the washer, then the o-ring, onto the probe blank
(refer Figure 4.15);
• When sliding the blanking plug into the housing, ensure that the blank is located ½ way into the probe
housing (refer Figure 4.15);
• Hand tighten the probe locking nut onto the probe housing, that will in turn tighten the washer onto the
o-ring (and create a seal). Repeat the process for all remaining probe blanks.
• The o-ring should not be lubricated when being fitted please ensure it is completely dry.

On the end of the pH probe lead is a locking BNC plug. The BNC plug for the pH probe needs to fit into
the back of the Davey Lifeguard controller, into the third BNC socket (refer Figure 4.16). The connector is
deliberately designed such that it fits only one way.

into the back of the Lifeguard controller, into the second BNC socket (refer Figure 4.17). The connector is
