Cleaning/Replacing 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
Close the ball valve on the storage tank.
2
Turn the re-pressurization pump off.
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.
Defender systems also have a drain plug installed on the bottom of the UV reactor. After releasing the water pressure at a faucet, remove this plug to ensure the system is fully drained.
CAUTION: If using the Defender system with a water reservoir tank, be sure to close the supply valve leading away from the tank to prevent gravity fed water from shooting through the UV during the replacement process.
4
Remove the captive ground screw from the ground lug on the UV reactor
5
Remove the lamp connector from the reactor (gland nut) by pushing the connector in and turning it 1/4 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 reactor
NOTE: Using gloves while handling the lamp will prevent damage.
7
Unscrew the gland nut from the reactor exposing the end of the quartz sleeve
8
Remove the quartz sleeve and O-ring by gently twisting and pulling the quartz sleeve
CAUTION: The sleeve can break if it is in a bind. There is a spring in the quartz sleeve. BE SURE not to lose the spring.
9
Using a soft, lint-free cloth or towel, wipe the sleeve down using a commercial scale cleaner (i.e. CLR or Lime-A-Way)
Alcohol wipes will work as well. 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 separate cloth
11
Install the clean tube into the UV Reactor. Install the O-Ring and gland nut
CAUTION: Be sure to put the quartz sleeve in the chamber straight. The sleeve can break if it is put in a bind.
12
Turn the re-pressurization pump on and open the tank valve.
Allow the system to pressurize and check for leaks. Repair leaks as necessary.
13
Re-install the spring then the lamp in the sleeve.
Be sure not to touch the lamp. It is best to wear gloves when handling the lamp.
14
Install the connector on the lamp and re-install the ground wire.
NOTE: The connector will only fit on the lamp one way. Make sure you have the plug installed properly.
