SAFETY EQUIPMENT REQUIRED TO PERFORM TASK
1. WARNING: Disconnect power to water purifi er.
2. Shut off water supply to water purifi er via inlet and outlet shut off valves. Drain chamber by removing drain plug. Once
the chamber is completely drained, remove any old sealing tape from the threads of the drain plug, rewrap with 1/2” wide
Tefl on® thread sealing tape, reinstall and tighten the drain plug.
3. Follow the steps in “Lamp Installation or Replacement” to remove lamp.
CAUTION: Lamp and quartz sleeve are easily damaged. Exercise care when handling.
4. Unscrew static gland nuts from each end of the chamber. Avoid striking quartz sleeve with static gland nut.
5. Remove Tefl on® washer and o-ring from both ends of quartz sleeve. Tefl on® washer will sometimes remain within the static
gland nut. If so, remove Tefl on® washer from static gland nut before proceeding.
6. Carefully remove quartz sleeve from chamber. NOTE: It is advisable to support the quartz sleeve on the opposite end
with your fi nger so that it does not drop to the bottom of the chamber as it slides into the chamber.
7. Once the quartz sleeve is removed, clean with alcohol or a mild, non-abrasive detergent. Stubborn stains usually can be
removed with a dilute hydrochloric acid. NOTE: Follow all manufacturer’s instructions and precautions when handling
chemicals.
8. Reassemble in reverse order. Make sure the quartz sleeve protrudes an equal distance past each threaded nipple. Be sure
o-rings are placed on quartz sleeve before Tefl on® washer.
9. Tighten static gland nuts fi rmly by hand only, DO NOT USE HAND TOOLS. Tightening with hand tools is likely to cause
quartz sleeve to break.
10. Slowly restore water supply to water purifi er and check for leaks.
11. If no leaks occur, reinstall lamp, following the steps in “Lamp Installation or Replacement” section.
WARNING: Germicidal ultraviolet rays are harmful to eyes and skin. Do not restore power to water purifi er until
lamps and both EASY-OFF
