3. Remove the wire nuts from the wires and sepARAte. The panel-side wires
(always on) will connect to “Line In,” and the heater load wires will connect to
“Output”
4. Loosen and remove the cable clamp from the junction box cover. Remove the
cover plate from the wires and set aside.
5. Unscrew the cover of the Apricity ARA and set the cover aside.
6. Check the length of the existing ground, it will need to pass through both
conduit ports on the ARA and return to the heater’s bonding screw or post in
the same way as it does without the ARA in place. Provide additional length with
a junction inside the ARA if necessary.
Mounting the Controller
7. Instructions are provided for mounting the ARA to either the water heater or to
the wall. We recommend mounting to the water heater where space permits:
Heater Mount:
• Remove one washer and one nut from the conduit fitting leaving the
closest to the ARA. Ensure the that the nut closest to the ARA is secure.
• Mount the cover plate from the water heater onto the conduit fitting at
the bottom of the ARA, with the ARA facing into the room. Replace
washer and nut, tighten.
• Thread the load wires from the hot water heater through the cover
plate and the connected hole of the ARA. Place the ARA and cover plate
back onto the hot water heater and fasten the cover plate in place using
the original screws.
o If the cover plate cannot be refastened to the heater with the
ARA in place, then install the supplied conduit fitting on the
cover plate with the ARA detached, fasten the conduit plate to
the hot water heater, and then install the ARA on the plate,
with the load wires threaded through the assembly as above.
Wall Mount (Alternative):
