The annual lamp change timer will run for approximately one full year. At the end of the one-year period, the lamp change timer will flash and the buzzer will sound. The flashing LED indicates that the timer function is in the 28-day grace period. Pushing the timer button during this grace period will silence the buzzer for seven days, but the LED will continue to flash. The buzzer reset can be pushed up to 4 times during this 28 day period. Under no circumstances, this grace period does not exceed 28 days. On the 29th day, the UV power source will indicate a lamp change alarm by illuminating the red timer LED continuously and sound the buzzer.

NOTE: The UV lamp is not shut down in this alarm mode and the solenoid valve drive is not disabled.

Resetting the Lamp Change Timer

The lamp change reminder timer is reset by disconnecting the UV power source from the AC supply, wait for fifteen seconds and reconnect 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.

Replacing the UV lamp and cleaning the quartz sleeve

NOTE: Do not touch the lamp or the quarts sleeve with your fingers. Handle by ENDS ONLY or wear soft gloves.

• Turn off all water supplies to the unit and unplug the system from the electrical outlet.
• Carefully extract the lamp connector from the sleeve gland nut 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 breaks.
• Carefully slide the UV lamp out of the quartz sleeve and discard according to local regulations.
• Remove the quarts sleeve by loosening the gland nut and carefully extracting it from the unit. CAUTION: The quartz sleeve is fragile and is easily chipped or broken – use care when removing or installing.
• Clean the quartz sleeve with a vinegar solution or a readily available scale removal product (Limeaway, CLR etc).
• Re-install the quartz sleeve – replace “O” ring if it appears damaged.
• Install new lamp by reversing procedure described in step 2 above.
• Slowly open the water supply valve and purge air from system – verify that there are no leaks before reconnecting to AC power.
