What to look for if:
• Outlet temperature is too hot with low flow:
1. The thermal actuator of the valve is not working properly.
Test and replace according to the appropriate technical
instructions, IS-P-MM430, IS-P-LM490-LM490-10 or IS-P-
SH1430 enclosed.
• Outlet temperature is too hot with a high flow:
1. The thermal actuator of the valve is not working properly.
Test and replace accordingly, IS-P-MM430 or IS-P-SH1430.
• Outlet temperature too low on low and high flow:
1. The hot water temperature is too low. You must have a sup-
ply temperature of at least 5º F (3º C) higher than the set
temperature. Readjust the hot water supply.
2. The checkstops on the hot side of the valve are not fully
open or may be stuck due to liming. Open and clean check-
stops.
3. The temperature has not been set properly on the small
and/or large valve. Refer to set up procedure and reset the
valves.
• Outlet flow drops off:
1. The checkstops are not fully open or stuck. Open and clean
checkstops.
2. The system pressure varies by more than 50% of the inlet
supply pressure.
• Outlet temperature cycles between hot and cold:
1. The system pressure varies by more than 50% of the inlet
supply pressure.
Troubleshooting
n
Thermostatic water mixing valves are control devices which
must be cleaned and maintained on a regular basis.
1. Before servicing checkstops or piping, turn off the water
upstream. At least every twelve (12) months, open up the
checkstops and check for the free movement of the poppet.
2. Before servicing the valve, turn off the water supply upstream
or close the checkstops. To close the checkstops, turn the
adjusting screw clockwise.
3. When opening checkstops after servicing, turn adjusting
screw counterclockwise to fully open position then turn
adjusting screw 1/2 turn clockwise for final setting.
4. Every three (3) months, check the maximum temperature
adjustments.
5. Every twelve (12) months, remove the valve bonnets and
check the internal components for freedom of movement.
CAUTION:
Any changes in supply condition could effect the out-
let water temperature. Check and adjust the valves
accordingly to prevent injury to the users.
