3. Loosen but do not remove the probe wire screw ( 9 ), then remove the orange probe
wire from the post.
4. Hold the probe arm securely and open the two spring clips ( 6 ) by grasping each at the
side closest to the black wire ( 5 ), then gently raising each to an open, locked position.
CAUTION
There is some spring resistance when attempting to open the clips. Do not
allow the probe arm to swing side to side when opening the clips.

Install the new DPP probe
1. Carefully insert the new probe into the probe guide ( 7 ), then slide the knurled nut of
the joint connector (
2
) into the back end of the probe and carefully tighten until snug.
2. Press the joint end of the probe into the joint holder ( 3 ).
CAUTION
Do not cross thread or force the joint connector in too far, to avoid damaging
the threads or introducing leaks or air bubbles.
3. Carefully close each spring clip (
6
) over the probe.
CAUTION
Do not allow the clips to snap on the probe shaft. This may cause damage to
the probe.
4. Reconnect the black wire ( 5 ) under the wire lock screw ( 4 ) and tighten the screw.
CAUTION
Do not flex the wire more than necessary. Over-flexing may damage the wire.
CAUTION
If the screw does not fully tighten, or the standoff spins, tighten the screw on
the probe arm base until the standoff no longer spins; otherwise the liquid-
level-sensing capability may be adversely affected.
5. Slip the orange wire onto the probe wire screw (
9
), then tighten the screw.
6. Carefully flex the tubing (
1
) and slip the flared end into the joint connector (
