WARNING!
ULTRAVIOLET LAMP REPLACEMENT
THE ULTRAVIOLET LAMP INSIDE THE REACTOR CHAMBER WILL
OPERATE EFFECTIVELY ROUND THE CLOCK, FOR APPROXIMATELY ONE
YEAR OR 8000 HOURS. THE LAMP WILL LIGHT LONGER THAN THAT,
HOWEVER, THE UV LIGHT PENETRATION MAY FALL BELOW THE
PRESCRIBED SAFETY LEVEL. THEREFORE, ANNUAL LAMP
REPLACEMENT IS NECESSARY REGARDLESS OF APPARENT LAMP
CONDITION.
Replacing the UV Lamp and Cleaning the Quartz Sleeve:
1. Unplug the system from the electrical outlet and turn off the water supply to
the unit.
2. Carefully extract the lamp connector from the electrical end cap assembly to
just expose the top of the UV lamp. While holding the lamp base firmly,
disconnect the lamp 4-pin connector. Lamp base can be very hot - be careful
not to drop the lamp into the quartz as both are easily broken.
3. Carefully slide the lamp out of the quartz sleeve and discard.
4. Loosen and remove both end caps. Roll back the o-rings at both ends and
remove. Carefully extract the quarts sleeve it from the reactor housing.
The
quartz sleeve is very fragile and is easily chipped or broken - use
extreme caution when installing or removing it from the reactor vessel.
NOTE:
Do not touch the lamp or quartz sleeve with your fingers. Handle by the
ends only or wear soft non-abrasive gloves.
5. Clean the quartz sleeve with vinegar or a readily available scale-removing
product. (Lime Away, CLR)
6. Examine the quartz sleeve o-rings. If they look worn or cracked, replace. Re-
install the quartz sleeve.
7. Install new lamp by reversing the procedure described in item #2 above.
8. Slowly open shutoff valves and purge the air from the system.
9. Ensure there are no leaks at the end caps before connecting the power to the
system.
