Symmons S-71 Series User manual

S-71, S-72, S-73, S-74 Series
INSTALLATION, OPERATION AND SERVICE INSTRUCTIONS
IMPORTANT:
• Water lines MUST be thoroughly flushed 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).
Note: Recommended minimum operating water supply
pressure is 40 psi.
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-shaped anchor bar (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 flat in center hole towards
the back of sink basin. Secure by tightening nuts from
underside. Insert faucet supply through deck plate aligning
flat on faucet body above threaded shank with flat 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 flange (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 flange and tube
from drain body and inserting tail piece into trap. Apply
bead of sealant to underside of flange and insert flange and
tube through drain opening. Place bottom gasket mounting
washer and mounting nut onto flange and tube assembly.
Screw drain body on tube until tight.
5. To flush 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 flushed. 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 specified.
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.
Cycle Time: Faucet is factory set to shortest cycle time with
6 timing washers (LL-28).
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.
Note: When setting MAXIMUM cycle time, you MUST
maintain at least 3 timing washers (LL-28) so as not to exceed
(per ASME A112.18.1) .25 gal/cycle at 60 psi.

SERVICE INSTRUCTIONS
TROUBLE SHOOTING CHART
Problem Cause Solution (Follow service instructions)
Faucet runs too long or too short Timing
Remove handle - then add washers (LL-28)
to stem to shorten time or remove washers
to lengthen time.
Faucet drips
Seat washer worn or foreign matter (chips,
dirt, solder, etc.) is between washer and
seat surface.
Disassemble cartridge and remove piston
(LT-4AA). Unscrew LL-4A and clean seat
washer (LL-37A). Checks S.S. pin (LL-24) for
burr then reassemble.
Faucet runs constantly Seat washer not closing on seat surface or
seat washer and/or seat surface worn.
Remove piston (LT-4AA) and spring (LL-32-JIB).
Check for burr on pin (LL-24) and check
spring. Both LT-4AA and LL-32-JIB may have
to be replaced. Excessive wear may require
cartridge replacement LL-1A.
