Symmons S-72 Series Manual

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 pro-
cedure (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.
Adjustment of cycle time
After faucet has been operated through a number of cycles
and supply water temperature is at designed level, adjust-
ment 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.
