CAUTION:
Broken Quartz is SHARP. It is recommended that protective goggles and gloves
are worn when handling broken quartz sleeves.
1. Disconnect power to water purifier.
2. Shut off water supply to the water purifier via the inlet and outlet shut off valves. Drain the chamber by
removing the drain plug. Once the chamber is drained, remove any old sealing tape from the threads of the
drain plug, rewrap with 1/2" wide Teflon
®
thread sealing tape, reinstall and tighten the drain plug.
3. Follow the steps in “ Lamp Installation or Replacement ” to remove lamp.
4. To prevent damage to the electrical components, it is necessary to separate the ballast housing from the
purifier chamber.
• On MightyPure
™ Models MP13A, MP16A, and MP22A, the ballast housing is mounted to the purifier
chamber using four (4) No. 8 x 3/8" long screws. Using a Phillips cross point screwdriver, carefully
remove the four (4) screws, from along the sides of the ballast housing, and set aside. Separate the
housing from the chamber.
• On MightyPure
™ Models MP36C, and MP49C , the ballast housing is mounted to the purifier
chamber using four (4) 1/4"-20 x 3/8" long hex head bolts. Using a 7/16" wrench or an adjustable wrench,
carefully remove the four (4) bolts with the lock and flat washers, from along the top of the ballast housing,
and set aside. Separate the housing from the chamber.
• Keep ballast housing and mounting hardware in a clean, dry area.
5. Unscrew static gland nuts from each end of the chamber. Remove Teflon
®
washer and o-ring from both ends
of quartz sleeve. Teflon
®
washer will some times remain within the static gland nut. If so, remove Teflon
washer from static gland nut before proceeding.
6. Carefully remove as much of the broken quartz sleeve as possible, from each end of the chamber.
7. To remove fragments of quartz sleeve, hold the purifier vertically and shake. The quartz fragments will
break and drop out of the purifier through the gland fitting. Flush water through chamber being careful to
remove all quartz fragments from the interior of the chamber.
8. Carefully discard all pieces of the broken quartz sleeve.
9. Align the end of the replacement quartz sleeve with the gland fitting of the chamber.
10. Carefully slide the quartz sleeve into the chamber, guiding it through the gland fitting. NOTE: Use care to
keep the quartz sleeve parallel to the chamber. Angling the quartz sleeve in any direction could result in the
breakage of the quartz sleeve.
11. As the quartz sleeve nears the far end of the chamber, support the quartz sleeve by inserting your finger
through the far end gland fitting and into the quartz sleeve. This will minimize the possibility of breaking the
quartz sleeve as it passes through the gland fitting.
12. Center the quartz sleeve in the chamber, making sure the quartz sleeve protrudes an equal distance past each
threaded gland fitting, of the chamber.
13. Re-install o-rings, Teflon
®
washers, and static gland nuts. Be sure o-rings are placed on quartz sleeve before
Teflon
®
washer. Tighten static gland nuts firmly by hand only, DO NOT USE HAND TOOLS. Tightening
with hand tools is likely to cause quartz sleeve to break.
14. Re-assemble ballast housing to purifier chamber, using hardware removed in Step 4.
NOTE: When re-assembling ballast housing to purifier chamber, electrical power cord should exit ballast
housing from the end mounted opposite the drain plug.
15. When all connections are complete, allow water to enter the water purifier at a low flow rate until the purifier
is pressurized. With the purifier pressurized, it should be checked for leaks.
16. See “ Lamp Installation or Replacement ” section to properly re-install the lamp into the
water purifier.

Germicidal ultraviolet lamps, like standard fluorescent lamps contain small amounts of mercury. Mercury added
lamps should not be placed in the trash. Dispose of properly.
For further information regarding the disposal and recycling of lamps containing mercury, along with Federal and State
requirements visit http://www.lamprecycle.org. Product Data Sheets for germicidal ultraviolet lamps can be found in the
“PDF Library for Ster-L-Ray
TM germicidal Ultraviolet Lamps” section of http://www.ultraviolet.com.
