9. The battery pack is connected to the processor boards by a six-pin Molex connector: do
NOT pull too hard or far on the battery pack or it will come unplugged and the unit will
need to be returned to WET Labs.
10. Gently pull the white cord at the loop to remove the battery pack from the pressure
housing.
11. Remove the black plastic protectors from the ends of the long screws securing the
batteries.
12. Loosen and remove the screws (3/16-in slotted driver).
4.2 Replacing End Flange and Batteries
1. Replace the batteries
2. Re-install the screws:
 Align the groove in each of the plates so the six-wire extension bundle will fit in it
along its length.
 Be careful not to cross-thread into the bottom end plate nor to over-tighten the screws.
 If they are too tight, the fiber washers that act as separators between the batteries will
flex.
 Make sure there are equal amounts of screw threads protruding from the bottom end
plate when they are secure. This will ensure the pack is straight and will fit into the
pressure housing with no difficulty.
1. Re-install the black plastic protective covers on the ends of the screws.
2. Remove and check the pressure housing O-ring for nicks or tears. Replace if necessary.
Before re-installing, apply a light coat of vacuum grease on the O-ring.
3. Carefully replace the battery pack in the pressure housing. Place the neoprene insulator on
the battery assembly and lay the white cord on the top.
4. Plug in the two-pin, then the six-pin Molex connectors. Sensor operation can now be
tested if desired.
5. Align the hole in the end flange (NOT the jack screw holes) with the white dowel pin.
While coiling the six wire bundle and making sure none are pinched between the end
flange and the pressure housing, position the flange on the housing. Leave space to re-
insert the gray foam spacer, making sure the cut-out accommodates the vent plug screw.
6. Push the end flange all the way on to the pressure housing, making sure no wires are
pinched. Be sure the vent plug does not pop up. If it does, you’ll need to re-position the
foam spacer.
7. Re-insert the monofilament.
