Cleaning the Quartz Sleeve
Depending on the water quality, the quartz sleeve may require periodic cleaning. At a
minimum, the quartz sleeve should be cleaned on an annual basis. The following steps outline
a basic cleaning procedure.
1. If a by-pass assembly is installed, shut the inlet valve off to prevent water flow through
the system. Otherwise, turn off main water inlet valve (and/or turn off the water pump).
2. Disconnect power cord of UV system from electrical outlet.
3. Release water pressure by opening a downstream faucet and then close the outlet
shut-off valve (if any). If there is no outlet shut-off valve, expect water to drain from the
system as the head pressure in the system will cause the water to flow back down.
4. Remove the captive ground screw from the ground lug on the UV chamber.
5. Remove the lamp connector from the UV chamber (gland nut) by pushing the lamp
connector in and turning it ¼ turn counter-clockwise. Disconnect the lamp connector from
the lamp.
CAUTION
: the lamp may be hot!
6. Being careful to touch only the ceramic ends, remove the lamp out of the UV chamber.
7. Unscrew the gland nut from the UV chamber exposing the end of the quartz sleeve.
8. Remove the quartz sleeve and o-ring by gently twisting and pulling the quartz sleeve.
9. Using a soft, lint-free cloth or towel wipe the sleeve down using a commercial scale
cleaner (i.e. Puretec SC1000). This removes scaling or iron deposits that may be on the
outside of the quartz sleeve. Be careful not to get any moisture or liquids inside of the
sleeve.
10. Dry the sleeve with a fresh cloth.
11. Replace the o-ring and slide the sleeve back into the reactor following steps 7 and 8
from the installation section of the manual.
