The coil harness "A" has a gray DEUTSCH connector on one end, and coil connectors to pumplets 1 and 2
on the other end. There are three wire colors (red, black, and white) for each coil connector. The coil
harness "A" is tied up to the main anchor (located between pumplets 2 and 3) and has 2 preassembled
anchoring ties.

DDP coil harness "A" removal

1. On the pump-to-controller harness end, disconnect the gray DEUTSCH connector of the coil harness
"A" (J001).
2. Disconnect all MCON connectors (A1, B1, C1, A2, B2, C2) from the valve coils (K600) of pumplets 1 and
2.
3. Using a 3 mm hex key, remove the M5x12 screws (J008) of the two anchoring ties (one is located
between pumplets 4 and 1 while the other one is between pumplets 1 and 2).
4. If the unit is a multi-outlet pump with an M1 pressure sensor, use a cable tie cutter to cut the cable tie
(J007) positioned under the M2 port.
5. If the unit is a multi-outlet pump with an M2 pressure sensor, use a cable tie cutter to cut the cable tie
located approximately 50 mm from the main anchor. This cable tie wraps around the coil harness "A"
bundle, the M2 pressure sensor branch and the M1 pressure sensor branch (if present).
Both cable tie positions can be seen in the figure Multi-outlet pump (sensors and harness AE).
6. Using cable tie cutters, cut the cable tie of the main anchor.
7. Safely remove the loose coil harness "A" from the pump harness and discard the screws.
