Place gasket (1) into groove on bottom of base ring (2). Place base ring onto sink over mounting hole, then install trim ring (3) over base ring. Tabs (4) on trim ring and base ring should be aligned together at the front and rear of the installation hole. Insert faucet lines and shank through mounting hole, then install hub (5) onto trim ring. Ensure that tabs on trim and base rings are correctly located in slots on bottom of hub. Install the mounting bracket (6) and nut (7) onto mounting shank (8) using wrench (9).

Model 16971-DST, 9181-DST, 9981-DST & 19922-DST

Place gasket (1) into groove on bottom of faucet (2). Insert faucet tubes and mounting shank (3) through mounting hole. Install mounting bracket (4) and nut (5) onto the mounting shank using wrench (6).

Optional Escutcheon Installation

Not included with all models – To order see replacement parts page for your model. For installations using the 10″ escutcheon, be certain and use the 10″ escutcheon (1) and under cover plate (2). Assemble under cover
plate and escutcheon in place of single hole trim ring. Place the shanks (3) of the escutcheon/under cover plate assembly into the mounting holes ofthe sink. Slide the tubes and shank of the hub (4) through the escutcheon and mounting holes, then install hub onto escutcheon. Ensure that tabs on escutcheon and plate are properly located in slots in bottom of hub. Mount as shown above using the nuts (5), bracket (6) and nut with wrench (7).

Water Line Connections

Ensure all fittings and end connections are free of debris.
Faucet fittings (1) are 3/8″ compression, with ends colored red for hot and blue for cold. Loop tubing (5) if it is too long.
Note: Recommended tubing minimum bend diameter is 8″. Secure metal nut (2) on faucet tube to supply valve connection (4) and hand tighten, then tighten one additional turn with wrench. DO NOT
OVERTIGHTEN. Repeat for other tube. WARNING: Do not use pipe dope or other sealants on water
A.line connections.
B. Custom Fit Connections
If you determine the PEX supply tubing for this faucet is too long and must be shorter to create an acceptable installation, be sure to read the instructions and plan ahead. When cutting the supply tubing the installer accepts the responsibility to do so in a way that allows a leak-free joint to be created. Delta is not responsible for tubing that is cut too short or cut in a way that will not allow for a leak-free joint.
For custom fit installations, you must use RP50952 sleeves (3) supplied with model and nuts included on supply lines. Tube cut must be straight. See plastic sleeve installation instructions found in RP50952 and
included in this document for more information. Secure metal nut (2) on faucet tube to supply valve connection (4) and hand tighten, then tighten an additional 2 turns with wrench. DO NOT OVERTIGHTEN.
Repeat for other tube.

Potential Problems and Remedies

Tubing is not cut perpendicular to the axis of the tube: carefully make an additional cut, being careful not to cut the tube too short.
Tubing is cut too short: buy a coupling union and a replacement supply line that mate together from a store. The coupling union end intended to connect to the faucet must mate to the standard 3/8″ connection
nuts and plastic sleeves supplied with the faucet.
The plastic sleeve or connection nut is lost: purchase a replacement nut and/or plastic sleeve that are designed to seal with PEX tubing. NOTICE: DO NOT use a metal sleeve, RP51243 gasket (supplied with faucet) or ferrule in the place of the plastic sleeve supplied, it may not create a leak-free joint.
WARNING: Do not use pipe dope or other sealants on water line connections.

Custom Fit Connections – Plastic Sleeve Installation Instructions

Identify desired length of tube (1). Leave 1″ – 2″ of extra length to allow for easier installation and cut tube. Ensure cut is straight and burr free.
Slide nut (2) and plastic sleeve (3) onto cut tube. Ensure sleeve is oriented as shown.
Insert tube into outlet fitting (4). Tube should touch bottom of hole inside fitting.
Slide plastic sleeve down tube until it engages top of fitting. NOTICE: Failure to use plastic sleeve in the correct orientation will result in disconnection and possible water damage.
Slide nut over plastic sleeve. With wrench, tighten nut 2 turns past finger tight.

Incorrect Installation

Do not install sleeve upside down.

Do not use RP51243 gasket (1) supplied with PEX tubing or brass ferrule (2) supplied with valve stops.
Ensure tube is fully inserted into stop before sliding sleeve down to engage top of fitting.

Flush Supply Lines
A. Place a bucket below outlet tube (1) and move the valve handle (2) to the open mixed position.
Note: To turn on faucet, pull the lever away from the faucet. Enjuague las líneas de suministro
B. Then, while holding the outlet tube (1) over the bucket, slowly open and close the supply stops
(3). This will prevent debris from being lodged in the hose and sprayer.
C. Move faucet handle (2) to the off position, and carefully remove container of water.

Hose Installation

A Insert hose end (1) through hose weight assembly (2).
B Push hose end (1) onto faucet outlet (3). Attach clip (4) over hose and outlet as shown. Pull down moderately to ensure connection has been made.

Turn on water supplies (1) and faucet valve handle (2). Check all connections at arrows for leaks. Refer back to the appropriate installation instructions and retighten if necessary. If assembled correctly, check for damage to seals and order appropriate replacements. Sprayer will lock into position when brought into proximity of the spout magnet. The sprayer can be removed by either pulling directly out from the spout or by twisting 90° in either direction which will cause the magnets to repel and the head to decouple from the spout (recommended).

Check the operation of the 2 function sprayer by pushing the trigger (A) from aerator to spray. For models with a 3 function sprayer, check the operation by pushing the buttons to achieve the 3 different modes.
Button 1 – Standard Flow Aerator
Button 2 – 1.5 gpm at 60 psi Maximum Aerator
Button 3 – Spray Mode
Note – 3 Function Sprayer returns to position 2 if left in position 1 when the water is turned off.

Setting The Handle Limit Stop (Optional)

This faucet includes an integrated handle limit stop that has two positions. Position
1, to the left, allows full handle motion (the full range between “all cold” to “all hot”).
The faucet is set in position 1 in the factory. Position 2, to the right, allows half of the normal handle motion (“all cold” to “mixed hot/cold”).
The handle limit stop can be adjusted by the homeowner once the faucet is installed. Setting the handle limit stop in position 2 may help to prevent scalding
because it limits the amount of hot water in the mix; however, this handle limit stop will not always prevent scalding because it does not compensate for incoming pressure or sudden water temperature changes.
To change positions of the handle limit stop: remove the handle; move the valve stem to the all cold position so the water is on; change the position of the handle limit stop; turn off the water; reinstall the handle.

Maintenance

If faucet exhibits very low flow
A. Remove and clean aerator (1) (Note: some models require wrench (2) to remove aerator.), or
B. Unscrew hose from spray head and clean debris from screen (the screen is located just inside the spray (3).
Note: Not all models have screens.
IMPORTANT: Reinstall screen to the spray head. (Failure to reinstall the screen could damage internal parts.)
If faucet leaks from under handle: Remove handle (4) and cap (5). Using a wrench, ensure bonnet nut (6) is tight.
If leak persists–SHUT OFF WATER SUPPLIES. Replace valve cartridge (7). When reinstalling parts, make sure bonnet nut (6) is tightened securely with a wrench.
If faucet leaks from spout outlet–SHUT OFF WATER SUPPLIES. Replace valve cartridge (7). When reinstalling parts, make sure bonnet nut (6) is tightened securely with a wrench.

WARNING: Failure to securely tighten bonnet nut with a wrench could result in water damage.
Note: A small amount of water may run out the spout or drip for a very short period after the faucet is shut off.
This is a natural occurrence caused by the long flexible hose.
Note: Do not attempt to disassemble cartridge (7). There are no repairable parts inside.

Cleaning and Care

Although its finish is extremely durable, it can be damaged by harsh abrasives or polish. To clean, simply wipe gently with a damp cloth and blot dry with a soft towel.

Backflow Protection System

Your Delta Faucet pull-out spout incorporates a backflow protection system that has been tested to be in compliance with ASME A112.18.3 and
ASME A112.18.1 / CSA B125.1. It incorporates two certified check valves in series, which operate independently and are integral, non-serviceable parts of the wand assembly.
