NOTE: The female end of the connector hoses is
designed to thread onto 3/4" pipe thread. Perform
appropriate plumbing to provide connections from
the water supply to the inlet hose/port and from the
outlet port/hose.

pointing towards the softener controls. The softener
inlet port will receive the hose which is connected
from the outlet of the carbon block filter.

NOTE: The outlet port is identified with an arrow
pointing away from the softener controls. The outlet
port will receive the 60" hose that will connect to the
