INSTALLATION PROCEDURE
NOTES:
1. WARNING: Make certain power is disconnected before servicing to reduce
risk of electrical shock.
2. This unit is intended for indoor use only.
3. For all plastic push-in type fitting connections, push tubing into fitting until it
bottoms out to ensure a watertight connection. To remove, depress collet and
pull tubing out.
4. O-rings on filter cartridge must be lubricated prior to insertion into filter head
to ensure a proper fit and seal.
5. There is an opening in the back of the unit to accommodate a waste bend. If a
plumbed waste is desired, a waste retrofit kit is available.
Refer to Installation Drawings for details. Use NSF-61 approved pipe joint sealant on all
threaded water connections.
STEP 1: Remove the rear cover/mounting bracket by unscrewing the four mounting screws
on the top and sides (requires a T30 Torx driver). The rear cover/mounting
bracket should now be free of the rest of the unit.
STEP 2: Open small box located inside main carton and remove drain basin assembly.
Install drain basin assembly into front of unit as indicated on Installation Drawing;
push in until snap latches are fully engaged.

INSTALLATION PROCEDURE
STEP 3: Unit is supplied with an external power cord. If desired, the power cord may be
removed and the unit may be wired through the back; see Installation Drawing for
rear electrical access location.
Install supply line in one of the locations shown in Installation Drawing (if bottom
inlet port is used, remove plug from port and install supplied grommet – for use
with 3/8” tubing).
Connect water inlet with screwdriver stop (not supplied).
Verify proper supply and electrical locations.
STEP 4: Secure rear cover/mounting bracket to wall; a number of mounting holes are
provided to fasten bracket direct to wall (fasteners not supplied; see Installation
Drawing for hole pattern).
Note that the unit weighs approximately 30 pounds. As such, attach rear
cover/mounting bracket using six 1/8” x 3” zinc-plated steel toggle bolts (in
conjunction with six appropriately-sized zinc-plated steel 1/8” fender washers).
Use level to verify horizontal and vertical frame mounting.
STEP 5: Apply a thin coat of NSF-61 o-ring lubricant (supplied) to the o-rings on the top of
the filter cartridge (avoid excessive application), firmly insert filter cartridge into
filter head, and twist (clockwise when viewed from bottom – see markings on filter
and filter head for alignment) until it stops (head and cartridge must be properly
aligned for cartridge to seat – note arrows on cartridge).
Attach filter monitor battery connector to filter monitor battery pack.
STEP 6: Use supplied magnetic key to unlock magnetic latch in plastic upper body panel –
place key on front of body panel opposite magnetic latch (see Installation
Drawing) and pull panel open (key will stay on panel by itself if it is in the right
location).
Slots are provided in the upper body panel for leverage; insert a screwdriver or
something similar to lever the panel open. Note: This can scratch the sheet metal
if done improperly.
At times, the tight fit between the magnetic latch and the sheet metal panel may
cause the magnetic latch to catch slightly on the edge of the sheet metal panel,
preventing it from retracting. If this happens, the door will not open. Press briefly
on the body panel in front of the latch to disengage the latch from the sheet metal
back panel.
Note the red lockout switch on the magnetic latch; this switch must be rotated
down toward the hinged plastic body panel in order for the latch to actuate.
STEP 7: Place unit onto rear cover/mounting bracket. Secure unit to mounting frame using
screws removed in step 1.
Complete inlet plumbing run between the screwdriver stop and the solenoid valve.
STEP 8: Open screwdriver stop wide open while checking for leaks at all connections.
STEP 9: Remove magnetic key and check to ensure that the red lockout switch is oriented
so the latch can lock. Close body panel. Store magnetic key in a secure location.
Be certain body panel is firmly in place. Provide AC power to unit.

INSTALLATION PROCEDURE
STEP 10: Activate unit by placing a bottle or cup in front of the sensor. If sensor does not
detect the object at the appropriate range, see Sensor Troubleshooting Guide.
The pressure regulator may need to be adjusted to better complement the input
pressure at the installation site. To do so, loosen jam nut on adjustment knob and
rotate knob as needed (move knob in to increase flow; out to decrease flow). Re-
tighten jam nut when the desired flow is obtained.
STEP 11: Water should be run through the system for approximately five minutes after the
unit is installed and anytime the filter cartridge is replaced in order to remove any
carbon particles and air bubbles from the system.
MAINTENANCE
NOTES:
1. WARNING: Make certain power is disconnected before servicing to reduce the
risk of electrical shock.
2. CAUTION: Do not use an abrasive cloth, brush, polishing compound, or
abrasive cleaner to clean any part of the unit.
3. Do not touch the circuit board for any reason.
4. The interlock switch below the fuse holder cuts the power to the unit whenever
the unit is opened from the front.
5. There is a red lockout switch provided on the magnetic latch that may be used
to hold the latch open. If desired, depress the latch and flip the red switch;
this should retain the latch in the “open” position.
STEP 1: Periodically clean the y-strainer located in the solenoid valve body.
STEP 2: The contaminant removal achieved by the unit’s filtration can also permit the growth
of bacteria. For this reason, the unit purges itself every 24 hours that of non-use.
However, bacteria may build up in the drain; therefore, it is recommended to
regularly clean the drain basin with a disinfectant such as Clorox® Disinfecting
Cleaner.
To access drain basin for cleaning, open the upper body panel and remove the two
screws holding the drain grate in place (requires T-20 Torx driver).
STEP 3: Periodically assure that the sensor window is clean on the outside.
STEP 4: The filter has a 2500 gallon capacity, but should be changed after approximately 2000
gallons, or sooner if flow output begins to decrease. Periodically open the upper
body panel, hold interlock switch down, and activate the unit (note that this will cause
water to dispense). The green LED of the filter monitor indicates that total gallon
setpoint has not yet been exceeded. If the yellow LED activates instead, this
indicates that 2000 gallons has been exceeded and the filter should be replaced.
Twist the filter cartridge clockwise a quarter turn (when viewed from the top) and pull
the cartridge down (it is not necessary to shut off the water supply; however,
lessening inlet pressure can make filter changes easier. Do not leave filter head
pressurized without a cartridge if a new cartridge is not going to be installed
immediately).
Apply a thin coat of NSF-61-certified o-ring lubricant (supplied) to the o-rings on the
top of the filter cartridge (avoid excessive application); cartridge may be damaged
otherwise. Firmly insert new cartridge and twist counter-clockwise (filter head and
cartridge must be aligned properly for cartridge to seat into head – note arrows on
cartridge). Reset the filter monitor by temporarily removing a battery (LEDs should
flash to indicate that monitor has been reset).
Water must be run through the new filter for approximately five minutes to remove
any carbon particles and air bubbles.

01/10 Model 2000SM Page 5 of 9
STEP 5: Filter monitor batteries should be replaced at least once a year. Note that when the
batteries are drained or are disconnected in any way, the flow counter resets to zero;
therefore, battery changes should occur at the same time as filter changes.
STEP 6: If blown, the power inlet fuse must be replaced. Only a Bussmann MDL-1/4 0.25-
amp time-delay fuse (or equivalent) should be used. This fuse is mounted on the
stainless steel back panel and is located behind the plastic body panel on the left-
hand side (see Installation Drawing). Press and twist fuse holder cap to release and
access fuse; reverse to reinstall.

TROUBLESHOOTING
PROBLEM REPAIR CHECKLIST
1. Insufficient water flow. a. Check that inlet screwdriver stop valve (not
supplied) is in the wide-open position.
b. Check that pressure regulator is sufficiently
open (clockwise to open).
c. Change filter cartridge.
d. Clean solenoid valve inline strainer.
e. Verify minimum 30 psi supply pressure.
2. Filter monitor does not indicate flow
(green LED) when water is dispensing.
a. Check that LEDs are plugged into monitor.
b. Replace batteries.
c. Replace filter monitor.
3. Continuous water flow. a. Solenoid valve sticking. Clear obstruction or
replace valve.
b. Check sensor window for obstruction; if it is
obstructed, it may have automatically shut
off after 30 seconds and will not reactivate
until the obstruction is removed.
c. Contact Haws Technical Support.
4. Unit does not activate. a. Check sensor window for obstruction; if it is
obstructed, it may have automatically shut
off after 30 seconds and will not reactivate
until the obstruction is removed.
b. Check to see if fuse has blown. Replace if
necessary; see step 6 under maintenance
section.
c. Check for power to unit.
d. Check that inlet screwdriver stop valve is in
the wide-open position.
e. See “Sensor Maintenance” Section.
5. Nozzle-mounted LEDs do not activate. a. See Sensor Troubleshooting Guide.
6. Water excessively splatters in drain. a. Turn down regulator (counterclockwise) to
lessen pressure.
b. Check to assure that mesh laminar flow
screens are still visible in end of nozzle. If
not, replace nozzle.
c. Examine nozzle for mineral deposits, etc.
(nozzle may be unbolted from inside).
7. Sensor trips randomly/sporadically. a. Unit is designed to self-purge every 24
hours that it is not used. This may be the
case here.
b. Contact Haws Technical Support.

SENSOR TROUBLESHOOTING GUIDE
NOTE: Sensor requires no calibration. If unit is powered, unit should activate when an
object is placed beneath the nozzle and in front of the sensor. Note that when the
sensor is triggered, the LED lights in the nozzle activate immediately, whereas the
solenoid valve opens after a slight delay.
Certain bottles or containers may not be readily detected by the sensor, either because
of their material or their shape. If this is the case, it may be useful to hold a different
region of the container in front of the sensor, or simply make sure that one’s hand is in
front of the sensor.
STEP 1: A click or hum indicates when the solenoid valve is activated. If valve clicks or hums,
but no water dispenses, make sure pressure regulator and screwdriver stop are
sufficiently open. If valve clicks or hums, but there is still little or no flow, check
solenoid valve, valve y-strainer, and plumbing lines for obstruction. If no obstructions
are located, replace valve.
If valve does not click or hum when hand is placed in front of sensor, go on to next
step. DO NOT ATTEMPT TO DISASSEMBLE SENSOR; DAMAGE MAY RESULT.
STEP 2: With power on and door closed, look closely at LEDs in nozzle assembly to confirm
that the LEDs are flashing at reduced brightness. This indicates that the unit is
receiving power.
STEP 3: If LEDs are not flashing, check the fuse and replace if necessary.
STEP 4: If fuse is good and LEDs are not flashing, use a voltmeter to check for 120 VAC at
the “Open” terminal of the interlock switch with the door opened. This verifies power
into the unit. Disconnect power and verify continuity between the two terminals of
the interlock switch while switch is depressed. If there is no continuity, the interlock
switch is not closing the power circuit and must be replaced.
STEP 5: If the above steps do not produce results, check for 120 VAC across the wiring
terminals on the solenoid valve while the sensor is triggered. Replace valve/regulator
assembly if a 120 VAC reading is obtained and water does not dispense.
STEP 6: If the above tests do not yield any conclusive results, contact Haws Technical
Support. Be certain not to attempt to troubleshoot or touch the main circuit board.
