Manual Cleaning of the Quartz Sleeve
To remove and clean the quartz sleeve, follow the steps shown below:
CAUTION: The UV lamp is sensitive to handling and should be allowed to fully cool before being moved. Wait at least 30 minutes after disconnecting power to
begin the removal process.
1. Disconnect Power
Unplug the device from its Power Outlet.
2. Stop the Circulation Pump
You must shut off the circulation pump so that no water is flowing into the vessel. When you are absolutely sure that there remains no pressure inside the
HydroRite vessel, you can proceed to the next step.
3. Drain the HydroRite System
You must drain the unit before any internal maintenance is performed. To drain, unscrew the threaded plug from the base of the vessel. NOTE: If the Acid Wash
system is plumbed, remove the hose to the shut-off valve from the base of the vessel. You can then open the valve to release the pool water.
4. Remove the Electrical Enclosure Cover
NEVER REMOVE THE VESSEL CAP WITHOUT FIRST UNPLUGGING THE CONTROLLER FROM ITS POWER SOURCE – DO NOT OPERATE THE UNIT WITH THE CAP
REMOVED - The vessel cap is removed by unscrewing the four mounting screws that hold the cap to the HydroRite vessel.
5. Remove the UV Lamp
To remove the lamp, grasp the lamp connector (at end of ballast cable) and rotate counter-clockwise (about 1/8 turn) to unlock the lamp from the vessel. Once
unlocked, slowly pull the lamp straight up and away from the quartz sleeve until it clears the vessel. DO NOT TOUCH THE UV LAMP WITH YOUR BARE HANDS!
Oils from your hands can attach to the lamp surface and create hot spots during operation and shorten lamp life. Use a soft clean cotton cloth (or cotton gloves)
to handle the lamp. Carefully place the lamp in a safe location.
NOTE: If you should touch the lamp with your bare hands, it can be cleaned with a soft cotton cloth and rubbing alcohol
6. Unscrew the Vessel Lock Nut
Grasp the two large "handles" on the vessel lock nut and fully unscrew (counterclockwise) the light engine.
7. Pull the Light Engine out of the Vessel
Using the handles on the vessel lock nut, lift the light engine straight up and out of the vessel.
8. Remove the Stainless Steel Baffle
There is a stainless steel baffle that surrounds the quartz sleeve which must be removed. To
remove the baffle, pinch the end in three places while pulling it away from the light engine (see
adjacent diagram). Pinching the baffle at those points will flex the surface enough to "unhook" itself
from the light engine.
