Power supply wire connection
1. Insert the power supply wires from lower right of the electrical control box and connect them to the power
terminal blocks and the grounding line to the grounding screw, and then fix each of the five wires with each
cord clamp and binding band.
2. When finished wiring the power supply wires, get each of five wires through the cutout on the sealing material
(black) under the cord clamp to pull it outside the electrical control box. Tear upper and lower of the cutout on
the sealing material with your hands before getting the wires through the cutout.
3. Get the binding band through two holes in the right part of the valve fixing plate and fix the power supply wires
with it.

Connection of power supply wires and communication wires
Remove knockouts on the piping / wiring panel on the front of the unit and the panel on the bottom to get the
power and communication wires through the holes.
1. Connect the power supply conduit to the field wiring panel.
2. Route the power supply wiring through the raceway and connect to the power supply terminal block and
ground screw.
3. Use ring terminals on field power wires if required by NEC and local codes.
