Determine the most practical under-the-sink location for placement of the Sierra manifold unit and the companion reservoir
tank. Ensure that the specific location allows adequate access to the manifold unit for cartridge re placement and to the
tank for tank- valve operation.
1. Place the manifold and tank in the selected locations. If desired, the #6 self tapping screws may be used to secure the
manifold unit in position by means of the top rear and bottom lip mounting holes.
2. Take the unused portion of the 3/8" white tubing and insert one end firmly into the 3/8" (largest) connector on the top of
the manifold unit.
3. Extend the 3/8" white tubing from the manifold unit to the tank valve. Leave enough slack in the tubing to allow the unit
to be removed from the installed location for servicing. Cut off the excess and insert the 3/8" tube into the quick-connect
tank valve fitting until it is fully engaged.
4. Extend the 1/4" yellow tubing from the faucet unit to the manifold. Leave enough slack in the tubing to allow the unit to
be removed from the installed location for servicing. Cut off the excess and firmly insert the tubing into the corresponding
yellow drain connection located on the manifold.
5. Extend the 3/8" blue tubing from the faucet unit to the manifold. Leave enough slack in the tubing to allow the unit to be
removed from the installed location for servicing. Cut off the excess and firmly insert the tubing into the corresponding blue
product water connection located on the manifold.
6. Extend the green tubing from the feed connector valve to the manifold. Leave enough slack in the tubing to allow the unit
to be removed from the installed location for servicing. Cut off the excess and firmly insert the tubing into the correspond-
ing green feed connection located on the manifold.
7. Obtain the Shutoff Warning label and affix it to the manifold unit so that it is directly visible. The Sierra system is now con-
nected and ready for initial test and preparation.
TUBING HINTS: Use a sharp knife or tubing cutter to cut the tubing squarely, being sure to remove all burrs. Then insert the
tubing firmly until it stops. To remove the tubing, push against the collet while pulling on the tubing.
