4. If mounting in wet environments, liquid-tight cables or
conduit fittings are required (not supplied) to ensure that the
enclosure maintains a water-tight, Type 4 rating. Install the
liquid-tight cables or conduit fitting into the conduit nuts in
front of the power supplied and motor connectors (fig. 5, 6).
WARNING: Liquid tight cables or conduit and fittings
must be used to maintain a Type 4 rating (fig. 5, 6). If
you use liquid tight cable (fig. 5), tighten the nuts to
a torque of 106 in-lbs (13 Nm). If you use conduit
fittings (fig. 6) tighten the nuts to a torque of
106 in-lbs (13 Nm). The nuts must compress the
O-ring to the body of the device.

Install the nuts with the arrow pointing towards the device as
shown in the figures.
The components labeled with X in Fig. 5 and 6 are not used for
the relative application.
5. Route supply wires through the conduit fitting into the wiring
chamber.
6. Connect the supply ground wires to the ground lug in the
wiring compartment.
NOTICE: The safety earth ground connection is marked at its
terminal using the (fig. 7, 8, 9).

7. Connect the supply wires to the screw terminal marked L
and N (fig. 7, 8, 9). Use only copper wires rated for at least
140°F (60°C). Lead wire terminals should be tightened to a
torque of 4 in-lbs (0.5 Nm).
8. Connect the motor wires to the screw terminal marked U
and V (fig. 7, 8, 9). Use only copper wires rated for at least
140°F (60°C). Lead wire terminals should be tightened to a
torque of 4 in-lbs (0.5 Nm).
9. Replace the cover and tighten the six screws. For proper
sealing, the screws should be tightened to a torque of 13
in-lbs (1.5 Nm).
6. STARTING
WARNING: Failure to follow this instruction may result in
heating of water, personal injury, pump damage, and/or
property damage. The device can be installed directly
on the pump or between the pump and the first tap
with the flow direction arrow facing upwards. Taps must
not be installed between the pump and the device (fig. 1).
WARNING: If the pressure generated by the pump
exceeds 174 psi (12 bar), apply a reducer between the
pump and the device.
Make all the electrical connections, check that the pump is
correctly primed, open a tap, and energize.
