3.2.1 Rotating the terminal box
To change the position of the terminal box,
follow these steps:
1. Remove the four (5 mm) allen-head screws
holding the pump head onto the pump
housing.
2. Carefully lift/slide the pump head out and
away from the pump housing. Next rotate
the pump head and locate the terminal box
in the desired position. The terminal box
can be rotated in steps of 90 °. Review
fig. 1 and fig. 2 for possible/permissible
positions. DO NOT locate the terminal box
beneath the pump.
3. Make sure the O-ring is properly seated in
the pump housing.
4. Replace the pump head onto the pump
housing.
5. Diagonally tighten the 5mm allen-head
screws evenly.
Torque to: 7 ft lbs. / 9.5 Nm.
6. Check to ensure the rotor turns freely. Do
this by removing the vent plug in the
middle of the pump nameplate. Insert a
medium-size, flat-blade screwdriver into
the slot at the exposed end of the shaft.
Gently turn the shaft. If it does not turn
easily, repeat steps 1 through 5 above.
If the rotor spins freely, proceed to step 7.
Do not put the vent plug back into the
pump until the end of step 9.
7. The position of the nameplate can be
changed by easing the outer edge of the
plate at the cutout with a screwdriver.
Turn the nameplate to the required position
and push into place.
8. Follow electrical instructions in section 3.3.
9. Refill the system, open the isolation valves
and vent the system. Also allow air to vent
out of the pump; once water flows out the
vent hole, replace the vent plug removed in
step 6. See additional instructions in
section 4.1.
10. Fig. 2 shows acceptable terminal box
positions along with recommended drip
loops (dashed lines) in the electrical wiring
harness based on entry point.

Use caution as the rotor
assembly can fall out of the
pump head or pump housing if
the pump head is pulled too far
away from the pump housing.
