Important: Some options may slightly alter installation. To ensure proper installation
review the Manual thoroughly and verify rough-ins before beginning any work. File this
Manual with the owner or maintenance personnel upon completion of installation.
ANSI, UFAS or ADA compliance is subject to the interpretation and requirements of the
local code authority and is the responsibility of the installer for verification.
Industry standard wall backing, for wall hung fixtures, is required. Installer provided wall
anchors and wall anchoring hardware with a minimum Pull-Out Force of 1000 pounds
(lbs) per anchor for appropriate wall construction.
Single Temp Valve Assembly: Recommended working water pressure is 30 PSI (2.07
bars) minimum to 100 PSI (6.89 bars) maximum. Maximum temperature is 130°F
(54.4°C). Maximum outlet temperature recommended is 105°F (40.6°C). Valve
assembly must be drained prior to being subjected to freezing temperatures. A
checkstop is provided with this valve assembly.
T/P Mixing Valve Assembly: Recommended working water pressure is 30 PSI (2.07
bars) minimum to 100 PSI (6.89 bars) maximum. Maximum hot water temperature is
180°F (82°C). Temperature adjustment range is 85°F-115°F (29°C-46°C). Minimum hot
water supply temperature must be 5°F (3°C) above desired set temperature. Valve
assembly must be drained prior to being subjected to freezing temperatures. The valve
assembly has checks integral to the inlets however, angle stops are to be provided by
the installer.
Teflon tape is recommended on threaded connections where applicable to reduce the
possibility of leaks.
Prior to installation, supply lines must be flushed of all foreign material such as pipe
dope, chips, or solder. Debris or foreign material in water supply may damage valve.
Provide 110-120 VAC/60Hz/3A (MAX) electrical receptacle for factory supplied
120VAC/9VDC, 100mA plug-in transformer.
Upon receiving, verify count and inspect packaging for obvious signs of damage or
missing containers. If there are any issues upon receiving make note on bill of lading and
report to carrier and manufacturer promptly. Remove fixture assemblies from packaging
and ensure all parts are present before beginning installation. Do not discard packaging
until all parts have been accounted for. Refer to Acorn terms, conditions of sales and
warranty for more information.
NOTE: Receptacle(s) must be wired to a GFCI protected circuit. Fixture must be earth
grounded per N.E.C. (National Electrical Code).

as pipe dope, pipe chips, solder, sand etc.
before making up supply connections.
NOTE: Installation should be in accordance with
accepted plumbing practices.
5) Turn on fixture and allow water to flow for 2
minutes. Measure water temperature at
outlet. If water is not at desired temperature,
adjust as necessary.
1) Locate suitable place for mounting the Valve
Assembly. Valve Assembly should be
accessible for service and adjustment and
as close to the point-of-use as possible.
Wall Anchors and Anchoring Hardware are
by others.
2) Connect hot and cold water to Supply
Valve using 1/2” NPTE connections.
3) Connect outlet of Tempering Valve to
Spout(s) using 1/4” O.D. Tube connections
provided.
4) Turn on hot and cold water supplies. If any
leaks are observed, hand-tighten
connections as necessary to stop leaks
before proceeding.
Valve Assembly Installation:
HINT: Angle Stops are recommended
and is the responsibility of the installer.
NOTE: Factory set temperature is 105º F
1) Loosen Locknut.
2) Turn on fixture and run water for at least 2
minutes. Allow supply temperature to
stabilize.
4) Tighten Locknut to prevent accidental or
unauthorized temperature adjustment.
5) Re-check outlet temperature.
3) Turn temperature stem counter-clockwise
for hotter or clockwise for colder outlet
temperature.

lMild soap / soft water solution
Corterra should be kept clean at all times. If maintained,
Corterra surfaces will retain their new, clean appearance
indefinitely. Wash with a non-abrasive all purpose cleaner
and water, then rinse. Wipe dry. (Never use cleaners with
strong chemicals such as toilet bowl cleaners, rust
removers, ceramic cook top cleaners, laquer thinners or
oven cleaners). To remove persistent stains use a Scotch
Brite pad and an abrasive cleaner or a solution of
household bleach and water (1 part water to 1 part
bleach).
Surface damage, such as minor chips, scratches, burn
marks and graffiti can be repaired with a fine grit abrasive
cleanser, such as a Scotch-Brite pad or fine grit
sandpaper. For more serious physical damage caused by
vandals, an Acorn Solid Surface Repair Kit is available.
Contact the factory for details. Refer to drawing #9927-
160-002.

For everyday cleaning, use a sponge or cotton cloth soaked
in mild soap and wipe-down surface. In industrial or marine
locations, close attention should be paid to regular care due
to harsher atmosphere.
To remove dirt and debris:
Fixture should be periodically washed with a diluted solution
of a mild non-abrasive detergent (e.g. Dawn ®) in cold or
ambient temperature water using a soft non-abrasive cloth
or chamois.
