Replacing the Conduit Bushing
Disconnect, lock out, and tag power at the panel before starting to
service the pump.
When servicing unit use non-sparking tools and use caution when removing or installing
equipment to avoid generating a spark.
enerating a spark.
Kits Required:
• Conduit Bushing (P/N 410486-001),
• Hardware/Seal Kit (P/N 410154-001)
Procedure:
1.
Remove the contractor’s box cover over the compression bushing (see Figure 15 on page 18). Remove and
discard the o-ring from the cover. Set aside the cover.
2.
Locate the conduit bushing at the base of the contractor’s box (see Figure 16 on page 19). Make a note of
which incoming wire connects to which pump wire then disconnect the incoming power wires from the pump
wires and set aside the wire nuts. Disconnect the blue ground wire and drain wire(s) from the green ground
wire (attached to the manifold) and set aside the wire nut.
If an I.S. Barrier is installed, make a note of which of the three inner tubing wires connect to the I.S. Barrier
then disconnect these 3 wires from I.S. Barrier wires. Also disconnect the I.S. Barrier cable’s drain wire in the
tubing from the green ground wire.
3.
Loosen the two screws in the conduit bushing just enough so the bushing can be lifted from its socket in the
bottom of the manifold’s contractor box. Continue lifting the bushing up, until it is free of the power/drain
wires.
4.
Orient the replacement bushing so the screws are facing up, and push each of the incoming power wires
through an empty outer hole in the bushing and push the tubing through the larger center hole in the bushing
as shown in Figure 18 on page 20 or Figure 19 on page 21 as required.
5.
Slide the bushing down over the power wires (outer holes) and tubing (center hole) until it seats in its socket
in the base of the manifold’s contractor box and then tighten the two screws in the top plate of the bushing
assembly to compress the bushing and seal the wiring entry.
6.
Reconnect the incoming wires to the pump wires as recorded in Step 2 above. Reconnect the blue power
wire and drain wire(s) to the green gound wire (attached to the manifold). Reconnect the incoming wires to
the I.S. Barrier wires as recorded in Step 2 above. Also reconnect the incoming drain wire in the cable to I.S.
Barrier to the green ground wire.
7.
Get a 2.090’’ ID x 0.118’’ wide o-ring from the hardware/seal kit. Lubricate the o-ring with petroleum jelly and
slide it over the cover’s threads up to the flange. Reinstall the cover. Do not use thread sealant. Torque the
cover to 35 ft-lbs (50 N•m).
