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.
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.
Industry standard wall backing, for wall hung fixtures, is required. Installer provided wall anchors and wall
anchoring hardware must be appropriate for wall construction, and have a minimum pull-out rating of 1000 lbs.
(453.6 kg).
Teflon tape is recommended on all threaded waste and supply connections to reduce the possibility of leaks.
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.
NOTE: When applicable, receptacle(s) must be wired to a GFCI protected circuit. Fixture must be earth
grounded per N.E.C. (National Electrical Code).

TROUBLE SHOOTING FOR 9 VOLT DC SENSOR OPERATED VALVES
Normal Valve Function: 9 Volt DC sensor operated valve has flow time of 90 seconds maximum.
To reactivate, the user must move out of and return to the sensing area.
CONDITION: WATER DOES NOT FLOW
Indicators Probable Cause Solution
Sensor flashes continuously
every 2 seconds when
hands are within range.
Low battery warning Replace battery
Circuit breaker tripped. Reset circuit breaker
Replace battery
Defective 9V DC transformer
Transformer polarity crossed Replace transformer (sensor may be
damaged and need replacement).
Unit is in “Security Mode” after
90 seconds of constant detection.
Remove sources of detection and
wait 30 seconds before checking.
Range is too short. Increase range.
Range is too long. Decrease range and wait 30 seconds.
Sensor is picking up a highly
reflective surface. Eliminate cause of reflection and wait
30 seconds before checking.
Sensor does not flash
when the user’s hands
are within range.
Defective sensor. Replace sensor.
Stops or water main closed.
Bad sensor to solenoid connection.
Debris or scale in
solenoid assembly.
Remove solenoid, pull out plunger
and spring, and clean with scale
remover solution or pressurized air.
Debris or scale in diaphragm. Remove diaphragm and clean
Sensor flashes once
when user’s hands are
within range.
Remove strainer and clean.
CONDITION: FALSE TRIGGERING;
WATER FLOWS CONTINUOUSLY
Indicators Probable Cause Solution
Remove diaphragm and clean. Sensor flashes when user’s
hands are within range. Diaphragm is defective or torn.
Sensor is dirty or covered. Clean or uncover sensor and
wait 30 seconds.
Decrease range and wait 30 seconds.
Sensor does not flash when
users hands are within range. Range too long or highly
reflective surface, sunlight, bright
lights etc. are triggering sensor. Eliminate cause of reflection or
correct lighting problem.
CONDITION: WATER FLOWS
CONTINUOUSLY BUT STOPS
WHEN HANDS ARE WITHIN RANGE
Indicators Probable Cause Solution
Water runs continuously when
sensor not activated. Sensor
flashes when hands are within
range and water shuts off.
Solenoid polarity crossed. Disconnect solenoid and
reverse polarity.
Battery completely used up.
Replace transformer.
Open stops or water main.
Ensure wires make proper contact.
Debris or scale in strainer.
Replace diaphragm.
Debris or scale in diaphragm

(Standard Satin Finish Only):
Use of synthetic, abrasive, general-purpose pads such as
Scotch Brite is recommended. Apply the stainless steel
cleaner/polish to the synthetic, abrasive pads and
CAREFULLY rub out spot with cleaner/ polish. Be sure to
rub in the direction of the grain! Do not allow steel wool to
come in contact with the stainless steel. Steel particles can
embed into the stainless steel surface and create rust!
FOR HIGH POLISH STAINLESS STEEL
Note: High polish stainless steel surfaces should never
come into contact with any abrasive cleaning brush, cloth or
cleaning agent.
To remove rust stains:
Wipe surfaces with CRES (available from Acorn) or
equivalent cleaner. Use recommended solutions. Apply
using a soft non-abrasive sponge. Rinse surfaces
immediately after application. Always follow cleaner product
directions provided. Afterwards, using a soft, non-abrasive
cloth, wipe surfaces with stainless steel cleaner/polish.
NORMAL CLEANING
Clean weekly or more often, as needed
(especially high polishing surfaces)
WARNING: Some soap contains corrosive additives that
can cause rust on stainless steel surfaces. Acorn
recommends user/ maintenance personnel review MSDS
reports of soap and possible corrosive additives noted.
Stainless steel should be kept clean at all times. If
maintained, stainless steel surfaces will retain their new,
clean, polished appearance indefinitely. To remove water
spots or rust spots, stainless steel cleaner/polish on a cloth
is recommended.
RECOMMENDED CLEANING MATERIALS
- Sponge – natural or artificial
- Nylon or other soft-bristle material brush
- Soft cloth (as used on automobile finishes)
To remove smudges and fingerprints:
Wipe surfaces with a quality Stainless Steel Cleaner/Polish.
Apply using a soft non-abrasive cloth, wipe surfaces with
stainless steel cleaner/polish.
IF SPOTS ARE STUBBORN OR IF YOU WISH TO TREAT A
SCRATCH: synthetic, abrasive, general-purpose pads such
as Scotch Brite are recommended. Apply the stainless steel
cleaner/polish to the synthetic, abrasive pad and
CAREFULLY rub out spot with cleaner/polish. Be sure to
rub in the direction of the grain! Do not allow steel wool to
come in contact with stainless steel. Steel particles can
embed into the stainless steel surface and create rust.
SOAP SYSTEMS
Acorn soap reservoirs and dispensers provide a dependable
operation over long term when proper maintenance is
performed and the correct soap is being used. The most
common problem with soap systems is that the wrong
viscosity (thickness) of soap is being used or high acidic pH
levels are in the ingredients. Soap thickness can be best
explained as no thicker or thinner than normal household
liquid dish soap. The pH level of the soap should be 6.5 to
8.5; more acidic soaps will corrode the metal parts and
degrade rubber or plastic components.
Soap reservoirs and dispensers should be maintained
periodically to clear residue. This should be done in hot
water to clean the internal components. The valve should be
pumped multiple times to thoroughly clean any residue
inside. The reservoir and tubing should also be flushed and
cleaned with hot water. In cases of extreme clogs, the
dispenser should be disassembled and the parts thoroughly
cleaned.
