Metering Faucet

S-71, S-72, S-73, S-74 Series

INSTALLATION, OPERATION AND SERVICE INSTRUCTIONS

IMPORTANT:

• Water lines MUST be thoroughly ushed BEFORE and AFTER installing the faucet to prevent foreign matter, i.e. copper chips, sand, stones, etc. from clogging and possibly damaging the sealing surface of the cartridge.

• Integral supply check included (S-73 and S-74 series only).

INSTALLATION:

(Supply stop valves must have a 3/8” O.D. compression outlet.)

1. Apply a bead of sealant to the underside of the faucet

escutcheon.

2. (S-72 and S-74 series): Install U-channel spacers (KN-23),

spacers (KN-26) and nuts (L-36) loosely on mounting bolts. Position deck plate (SPF-28) and mounting gasket (SPF-27) under base through sink with at in center hole towards the back of sink basin. Secure by tightening nuts from underside. Insert faucet supply through deck plate aligning at on faucet body above threaded shank with at in deck plate center hole. Secure faucet to deck plate by placing the washer (K-60), locknut (SPF-38) and hex nut (SPF-26) on the supply shank. Hand tighten only! Adjust position of faucet to achieve optimum spray into basin. Tighten faucet securely to basin or deck plate. (S-71 and S-73 series): Insert faucet with ange (SPF-5) through hole in basin. Secure faucet to basin by placing the washer (K-60), locknut (SPF-38) and hex nut (SPF-26) on the supply shank. Hand tighten only! Adjust position of faucet to achieve optimum spray into basin. Tighten faucet securely to basin.

3. Connect 4-10C mixing valve to bottom of supply shank using

supply nut provided (S-73 and S-74 series only). Make connection to water supplies using the appropriate connectors.

4. Install grid drain (if applicable) by removing ange and tube

from drain body and inserting tail piece into trap. Apply bead of sealant to underside of ange and insert ange and tube through drain opening. Place bottom gasket mounting washer and mounting nut onto ange and tube assembly. Screw drain body on tube until tight.

5. To ush faucet, remove spray outlet, using vandal proof

wrench (LL-60K) provided with faucet. Open cold supply and depress handle holding down for ten seconds (S-71 and S-72 series only). Open hot supply and repeat above procedure (S-73 and S-74 series only). Allow faucet to shut off and replace spray outlet.

Temperature adjustment (S-73 and S-74 series only)

Make sure the faucet has been properly installed and thor-

oughly ushed. Set the mixing valve (4-10C) to the desired maximum temperature by inserting a 1/4” hex socket key into the mating hex socket in center of valve and turning counter clockwise for hotter, clockwise for colder. 110ºF recommended unless otherwise specied.

S-71/S-73

S-72/S-74

Adjustment of cycle time

After faucet has been operated through a number of cycles

and supply water temperature is at designed level, adjustment of this feature can be made as follows.

Loosen set screw (LL-27) in cap (SPF-104), remove cap. To

increase time, remove one or more of the washers (LL-28) on stem. To reduce time, add washers. When desired time cycle is achieved replace cap and tighten set screw.
