Symptom Possible Causes Solutions
• Run water until it return to ambient temperature.
• Install temperature management valve

away from UV (ie. pump or fridge).
• UV system should not be installed on a circuit which is incorporated into a light switch.
DISPLAY FAULT MODES
• Lamp life expired - countdown is at “0” days
• Press reset button for a deferred alarm, replace UV lamp
