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.

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.
