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 replacement 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" (larg-
est) 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 mani-
fold.
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 corresponding 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 connected 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.
