Culligan Smart Controller HE DF 12 Installation, Operation, And Service Instructions With Parts Lists page 20

Straight-Through Adapter
Each filter is shipped with a Culligan® straight-through adapter to connect the filter to the plumbing system.
CAUTION!
Straight-Through Adapter Installation
Refer to Figure 15 and the instructions below to connect the
meter, straight-through adapter, and interconnecting pipe.
1. All HE 1.5 units are equipped with a meter. The
meter is installed on the outlet side of the control
valve. The meter body fits in the same space as the
coupling between the control valve and the straight
through adapter. Make sure the arrow on the flow
meter is pointing in the direction of the flow.
2. The straight-through adapter connects directly to
the control valve with the meter and coupling and
two assembly pins. Lubricate all O-rings on the cou-
plings/meter with silicone lubricant. See Figure 15.
NOTE The Low Flow Meter has a white dot on the
connection for the wire harness.
NOTE If the ground from the electrical panel or breaker box to the water meter or underground copper pipe
is tied to the copper water lines and these lines are cut during installation of the straight-through
adapter, an approved grounding strap must be used between the two lines that have been cut in order
to maintain continuity. The length of the grounding strap will depend upon the number of units being
installed. In all cases where metal pipe was originally used and is later interrupted by the straight-
through adapter to maintain proper metallic pipe bonding, an approved ground clamp c/w not less
than #6 copper conductor must be used for continuity. Check your local electrical code for the correct
clamp and cable size.
CAUTION! Close the inlet supply line and relieve the system pressure before cutting into the
plumbing! Flooding could result if not done!
CAUTION! When making sweat connections, use care to keep heat away from the plastic nuts
used to connect the plumbing to the bypass. Damage to these components may result
otherwise.
