IN ORDER TO PERFORM THIS TASK, BE SURE TO WEAR THE FOLLOWING SAFETY
EQUIPMENT: SAFETY GLASSES OR A FACE SHIELD, AS WELL AS GLOVES.
1.
Disconnect power to water purifier.
2. Shut off water supply to water purifier via inlet and outlet shut off valves. Remove drain plug and drain the chamber. Once
the chamber is completely 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.
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 Teflon
®
washer and O-Ring from both ends of quartz sleeve. Teflon
®
washer will sometimes remain within the static
gland nut. If so, remove Teflon
®
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 finger 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 Teflon
®
washer.
9. 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.
10.
Slowly
restore water supply to water purifier and check for leaks.
11. If no leaks occur, reinstall lamp, following the steps in
“Lamp Installation or Replacement”
section on
page 11
