Lamp Change Procedure

Replacing the UV lamp and cleaning the quartz sleeve

Note: Do not touch the lamp or the quartz sleeve with your fingers. Handle by ends only or wear soft gloves.

1. Turn off all water supplies to the unit and unplug the system from the electrical outlet.
2. Carefully extract the lamp connector from the sleeve glandnut assembly to expose just the top of the lamp. While holding the lamp base firmly, remove the lamp power connector. Caution: lamp base can be very hot – be careful not to drop lamp into quartz sleeve as it easily broken.
3. Carefully slide the UV lamp out of the quartz sleeve and discard according to local regulations.
4. Remove the quartz sleeve by loosening the glandnut(s) and carefully extracting it from unit. Caution: The quartz sleeve is fragile and is easily chipped or broken – use care when removing or installing.
5. Clean the quartz sleeve with a vinegar solution or a readily available scale removal product (Limeaway, CLR etc.). Quartz sleeves should be replaced at least every 3 years or sooner, if severe fouling has occurred.
6. Re-install the quartz sleeve – replace “O” ring.
7. Install new lamp by reversing procedure described in step 2 above.
8. Slowly open water supply valve and purge air from system – verify that there are no leaks before reconnecting to AC power.

Resetting the Lamp Change Timer

The lamp change reminder timer is reset by disconnecting the UV power source from the AC supply, waiting for fifteen seconds and reconnecting to the AC supply while depressing the timer button. The UV power source will emit a solid three second beep indicating that the reset was successful.

It is not possible to reset the lamp change timer unless the timer is in the grace period or lamp change alarm mode. If you need to reset the lamp change timer prior to the full one year time period expiring due to premature lamp failure, there are special instructions included with all replacement lamps describing the necessary procedure.

Time remaining: Pressing the button when the lamp change reminder timer is not in the grace period or lamp change alarm mode will display the lamp life remaining in weeks on the two digit display.

Note: The UV power source is designed to shut down if the AC input voltage is outside of operating limits. When a lamp failure alarm is active you should unplug the unit from the AC power source, wait for fifteen seconds and then reconnect to the AC power source. If the failure was due to out of limit AC power the unit will re-ignite the lamp and operate normally.

UV Power Source ERROR Codes

E1 – Low UV Intensity
E3 – Sensor Error
E4 – Solenoid Override Active
E5 – Change Lamp
E7 – Sensor Self Test Failure

UV Power Source Operational Display Codes

oh – Overheat Mode
ND – No Data

Low UV Intensity: If the output of the UV detection system falls below 50%, a low UV alarm will be initiated and error code E1 will be displayed. If a solenoid valve is installed it will be deactivated to stop the flow of water.

Sensor Error: If the UV sensor is not connected to the UV power source, or if the sensor is malfunctioning, error code E3 will be displayed. Verify that the sensor plug is fully inserted into the UV power source before replacing the UV sensor.

Solenoid Override: The UV power source has a solenoid override feature to enable emergency water flow when the system has entered a low UV alarm state. Pressing the button during error code E1 will initiate the override, which is active for 6 minutes, but can be reset indefinitely. Error code E4 will display while the solenoid override is active. The solenoid override feature will not function if the lamp has failed. Caution: the water treated by the unit will not be properly disinfected when the solenoid override is in operation.

Change Lamp: The annual lamp change timer will flash and the buzzer will sound after approximately one year. Pushing the button will silence the buzzer for a 7 day period, but the LED will continue to flash. After 28 days the buzzer cannot be silenced, and error code E5 will display. Note: The UV lamp is not shut down in this alarm mode and the solenoid valve drive is not disabled.

Sensor Self Test Failure: The system includes a sensor self test mode which is automatically executed if the diagnostic display is activated. If the sensor fails the self test, the E7 error code is displayed and the sensor will need to be replaced.

Overheat Mode: This code is not an error code, simply a display code that tells you the system is currently in the overheat mode, meaning the chamber temperature has exceeded 45C (113F). The system is still operating while this code is displayed.

No Data: This code is not an error code. When the system is first turned on ND will display until the sensor begins transmitting information to the power source. This code should clear after a few minutes of operation.
