TROUBLESHOOTING
PROBLEM REPAIR CHECKLIST
1. Continuous flow from freeze bleed valve. 1. If bleed water temperature is above 45ºF (7ºC),
service bleed valve. For specific instruction regard-
ing removal, maintenance and re-installment of this
model, contact Haws Technical Support at 1-800-
640-5612. If below 45ºF (7ºC), verify electric power
to unit, then check thermostat. See item 3 below.
Once opened, cold supply water, (45ºF (7ºC), will
keep freeze bleed valve open. To shut bleed valve,
it must be warmed above 45ºF (7ºC).
2. Continuous flow from scald bleed valve.
(Optional valve).
2. If bleed water temperature is below 90ºF (32ºC),
service bleed valve. For specific instruction regard-
ing removal, maintenance and re-installment of this
model, contact Haws Technical Support at 1-800-
640-5612. Above 100ºF (38ºC) may be due to
direct sunlight or excess ambient temperature.
3. Shower and eye/face wash water tem-
perature below 40ºF or above 100ºF.
3. Shut off electric power. All electric connections
are made inside external junction box. Thermo-
stat is mounted below junction box. Check
thermostat leads to terminal block for good con-
nections. Check thermostat setting: open ther-
mostat side cover and check that temperature
dial is set at 80ºF. Self-regulating heat trace ca-
ble will not overheat shower until air tempera-
ture rises above 85ºF (30ºC).
4. Removal of thermostat. 4. a. Disconnect the black, red, and green wires at
the thermostat (see page 8 of 8 for schematic).
b. Disconnect the black, red, and green wires at
the junction box.
c. Loosen set screw on kee-klamp and disassem-
ble the union between the junction box and
thermostat (see page 7 of 8 for clarification).
d. Remove thermostat from the shower assembly
(remember to de-pressurize the shower prior to
removal of thermostat and drain excess water
by activating eyewash). Hold coupling into which
thermostat is threaded firmly during removal in
order to keep it securely attached to shower as-
sembly; otherwise a leak may occur under the
jacket.
5. Insufficient flow at shower and eye/face
wash.
5. Verify minimum 30 PSI (2 ATM), 28 gallon (106
liters per minute) available supply. Check for
blockage in lines.
6. Insufficient flow at eye/face washes only. 6. Probable clogging of flow control due to inade-
quate line flushing. Turn water supply off. Un-
screw eye/face wash head and adapter to gain
access and clean flow control.
7. Insufficient water flow at the shower-
head, however, eye/face wash is suffi-
cient.
7. Probable clogging of flow control inside shower-
head. Unscrew showerhead off of elbow and
clean rubber flow control.
