OPTIONAL INSTALLATION
CONNECTING THE PB4RO-75 TO
REFRIGERATOR ICEMAKER/WATER
DISPENSER
CAUTION
If you are connecting the PB4RO to your
refrigerator/icemaker with initial system
installation, wait to turn on the icemaker until
the Post- Filter Cartridge (on the right side of the
filter housing) has been flushed according to
Step 11.
CAUTION

copper tubing or brass fittings.
NOTE: For optimum performance, it is recommended
that the distance between the PB4RO and the
refrigerator icemaker/water dispenser be no greater
than 10 feet (3 m). At distances greater than 10 feet,
the water pressure from the system may not be
adequate to deliver water to the refrigerator.
