Cleaning the Quartz Tube

When to Clean the Quartz Tube

The UV lamp is housed in a Quartz tube.

If the quartz tube becomes dirty, its ability to transmit rays from the UV lamp will be diminished and decrease system performance.

The quartz tube should be removed from the DEL AOP S at least once a year for inspection and cleaning.

Use Precaution

Wear proper eye and skin protection when cleaning glass components.

Removing the UV Lamp

  1. Make sure the DEL AOP S is drained of pool water and has cooled before cleaning.
  2. Disconnect the power connector between the UV lamp and wire harness.
  3. Gently pull on the UV lamp wires until the top of the UV lamp is out of the UV lamp retainer.
  4. Grasp the white ceramic end of the UV lamp and pull until it is fully removed.
  5. Avoid touching the UL lamp glass with your bare hands.
  6. Handle the UV lamp carefully and set aside.

Disassemble the UV Lamp Retainer

  1. Remove the two screws and washers from the top of the UV lamp retainer & pull the UV lamp retainer out of the quartz tube adapter. Any remaining water will drain from the AOP when the UV lamp retainer is removed.
  2. Grasp the inside of the quartz tube and pull it out of the housing. Make sure the sealing o-ring does not get lost during quartz tube removal.
  3. Inspect the quartz tube for cracks and replace if cracks are found.
  4. Inspect the sealing o-ring for nicks or hardness and replace if necessary.

How to Clean Quartz Tube

  1. Clean the quartz tube exterior with a mild solution of muriatic acid and water in a ratio of four parts water to one part acid (4:1). Follow the directions for safe use and handling of muriatic acid on the acid bottle label. Never add water to acid. Always add acid to water. DO NOT USE ABRASIVE CLEANERS.
  2. After cleaning the quartz tube, wash it off with water and wipe dry with a soft towel.
  3. Make sure the inside of the quartz tube is dry before installing the UV lamp.

Reinstall the Quartz Tube and UV Lamp Retainer

  1. Place the sealing o-ring on the quartz tube 3/4 inch from the open end.
  2. Insert the quartz tube partially into the quartz tube adapter.
  3. Place the UV lamp retainer over the open end of the quartz tube and slowly push in until it is touching the quartz tube adapter.
  4. Reinstall the two screws and washers and tighten until the UV lamp retainer is seated completely against the quartz tube adapter.
  5. Turn on the pool pump and check the joint around the UV lamp retainer for leaks.
  6. Once you have confirmed that there are no leaks, turn off the pool pump.

Reinstall the UV Lamp

  1. Make sure to only handle the new UV lamp by the ceramic ends.
  2. Clean the UV lamp with a lint free cloth and rubbing alcohol before installation if needed.
  3. Carefully push the UV lamp into the UV lamp retainer until the top of the UV lamp is past the tabs on the UV lamp retainer.
  4. Reconnect the UV lamp power connector to the wire harness.
