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.
NOTE: Receptacle(s) must be wired to a GFCI protected circuit. Fixture must be earth
grounded per N.E.C. (National Electrical Code).
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.
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.
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.
Teflon tape is recommended on all threaded waste and supply connections to reduce the
possibility of leaks.
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.
Provide 110-120VAC/60Hz/3A (MAX) electrical receptacle for factory supplied
120VAC/9VDC, 100mA plug-in transformer if required.
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.
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 85-115°F (29-46°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

Instructions for Operation and Care of Best-Care WH3740
Programming Instructions (Flow Time Adjustment)
Programmable Piezo Pushbutton
THE TIME SETTINGS PROGRAM USES 3 DIFFERENT TIMING MODES:
— 5 second timing mode: Each push of the button adds 5 seconds to the total timing cycle.
— 1 second timing mode: Each push of the button adds 1 second to the total timing cycle.
— 20 second timing mode: Each push of the button adds 20 seconds to the total timing cycle.
To program the piezo pushbutton, you will need to be able to see the back of the piezo pushbutton.
Prevision must be made to access the back of the piezo pushbutton. There is an LED on the back of the piezo
pushbutton under a layer of transparent epoxy, used as a programming indicator light (see page 3).
In order to start the programming the piezo pushbutton, the button must be powered down. Disconnect the red power
cable and wait 20 seconds, then reconnect the red power cable.
As soon as the cable is reconnected the LED will start flashing, it will flash 4 times, then stays on for 3 seconds.
During the 3 second period, push the piezo button once, the LED will go out, now you are in the 1 sec timing mode
and each time the button is pushed the LED will flash, adding 1 sec to the total timing cycle.
To move on to the 5 sec timing mode, pause and wait for the LED to flash 2 times, now you are in the 5 sec timing
mode. Each time the button is pushed the LED will flash, adding 5 sec to the total timing cycle.
To move on to the 20 sec timing mode, pause and wait for the LED to flash 3 times, now you are in the 20 sec timing
mode and each time the button is pushed the LED will flash, adding 20 sec to the total timing cycle. After programing
is complete, pause and wait for the LED to flash 4 times and then 5 times, which completes the programming.
GENERAL NOTES:
— When a timing mode is not required then do not push the button and wait for the next timing mode.
*See work sheet on page 2 which will simplify the programming procedure.
— Each timing mode (1 sec, 5 sec or 20 sec timing mode) can be sequenced up to 100 times, that is
the number of times, the button can be pushed, to increase the total timing cycle in each timing mode.
NOTE: This programming procedure moves along rapidly, there is
only about 2 or 3 seconds between programming operations.
The Button is factory set an 8 sec. timing cycle, if an 8 sec. cycle is adequate, then no programming adjustment
is required. Pushing the button during the timing cycle will stop the cycle (Cycle Interrupt).
NOTE: Read the entire document before
trying to program the piezo pushbutton.*
