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 regarding
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 regarding
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
temperature below 40ºF or above 100ºF.
3. Shut off electric power. All electric connections are
made inside external junction box. Thermostat is
mounted in top port of junction box. Disconnect
thermostat leads from terminal block and wire nut in
junction box. Check thermostat continuity: open
circuit above 65ºF (18ºC), closed below 45ºF (7ºC).
Thermostat is not adjustable and should be replaced
if either of the continuity checks are incorrect. If unit
is subject to freezing temperatures, temporarily
disconnect thermostat and reconnect wiring to
bypass thermostat and protect shower from freezing
until replacement thermostat can be installed. Self-
regulating heat trace cable will not overheat shower
until air temperature rises above 85ºF (30ºC).
4. Insufficient flow at shower and eye/face
wash.
4. Verify minimum 30 PSI (2 ATM), 28 gallon (106 liters
per minute) available supply. Check for blockage in
lines.
5. Insufficient flow at eye/face wash only. 5. Probable clogging of flow control due to inadequate
line flushing. Turn water supply off. Unscrew
eye/face wash heads and adapter to gain access
and clean flow control.
6. Insufficient water flow at the showerhead,
however, eye/face wash is sufficient.
6. Probable clogging of flow control inside showerhead.
Unscrew showerhead off of elbow and clean rubber
flow control.
7. Shower and eye/face wash valve stem leak. 7. Remove shower arm or eye/face wash push flag.
Peel black trim strip from shower and separate
housing halves. Peel back or remove insulation to
gain access to valve. Remove “U” bracket from valve
stem and tighten valve stem hex packing nut to stop
leak. Reassemble bracket, insulation, shower
housing and valve arm.
8. Shower and eye/face wash valve leaks.
(Does not shut off completely).
8. Disconnect power to unit. Disassemble as in item 6.
Check valve arm stop tang for damage. Repair or
replace valve assembly. Heat cable is looped around
valve and should be pulled away from valve. Remove
valve. Reverse above steps to reassemble.
