Step 5: Remove the lamp connector from the chamber (gland nut) by pushing the connector in and
turning it ¼ turn counter-­‐clockwise (gently pull on the lamp cable to ensure the connector is seated
properly).
Step 6: Pull lamp out of chamber still attached to connector.
Step 7: Remove the gland nut from each end of the chamber exposing the ends of the quartz sleeve.
Step 8: While holding on to both ends of the sleeve carefully remove the O-­‐ring from the end opposite
from the lamp connection and then pull the quartz sleeve out of the chamber (ensure that no water
enters the inside of the quartz sleeve); remove second O-­‐ring
Step 9: Using a soft, lint-­‐free cloth or towel wipe the sleeve down using a good commercial scale cleaner
to remove any scaling or iron deposits that may be on the outside of the quartz sleeve. Be careful not to
get any moisture or liquids on the inside of the sleeve.
Step 10: Wipe the sleeve with separate dry cloth.
Step 11: Once the sleeve is cleaned slide it back into the chamber following the steps outlined.
Step 12: Replace both O-­‐rings.
Cleaning the UV Sensor (if applicable):
Depending on the water quality, the UV sensor may require periodic cleaning. At a minimum, the UV
sensor should be cleaning on an annual basis. The following steps outline a basic cleaning procedure.
Step 1: If the system has an inlet shut-­‐off valve, shut this valve off to prevent water flow through the
system. If there is no inlet shut-­‐off valve, turn off main water inlet valve (and turn of water pump if you
have one).
Step 2: Disconnect power cord of UV system from electrical outlet.
Step 3: Release water pressure by opening a downstream faucet and close the outlet shut-­‐off valve if the
installation incudes one (if there is no outlet shut-­‐off valve, be prepared for water leakage from the
system as the head pressure in the system will cause water to flow back through the outlet plumbing and
through the chamber).
Step 4: Place something under the chamber to catch any water that may come out of the chamber
during the removal of the UV sensor.
Step 5: Unscrew (counterclockwise) sensor nut from the chamber and pull the sensor slowly out of the
sensor port.
Step 6: Holding the sensor in your hand wipe the flat portion (sensor face) of the sensor with isopropyl
alcohol using a clean lint-­‐free cloth.
Step 7: Replace sensor as per instructions of this manual.
