The R0992500 (Previously 9-1204-01) Quartz Tube for DEL Ozone AOP 25 S and DEL Ozone Spa Solar Eclipse. 

The AOP 25 S and Spa Solar Eclipse each have one UV-C Lamp inside a Quartz Tube, which is inside the UV Reactor.  When the Quartz Tube becomes dirty, the ability to transmit UV rays from the Lamp is diminished.  Every 6 months, clean the UV Lamp's Quartz Tubes.  Download instructions below in our RESOURCE CENTER.

Occasionally, the Quartz Sleeve gets broken and needs to be replaced.  This is not common, so we do not encourage you to stock up on Quartz Sleeves!

AOP and Spa Solar Eclipse Quartz Tube:

• Length is 11 1/4"
• Diameter is 1"
• 7-1862-01 is the part number for the Quartz Sleeve ONLY and it is hard to ship a Quartz Tube without packaging (so we use 9-1204-01 which is ready for shipping!)
  
• 9-1108-01 is a part number found in the first round of Spa Solar Eclipse Manuals and is no longer applicable.  Use 9-1204-01
• R0992500 (Previously 9-1204-01) is the 7-1862-01 Quartz Sleeve with all the packaging to ensure it won't break during shipping.  This is the part number DEL Ozone uses currently for the DEL Ozone AOP 25 and DEL Ozone Spa Solar Eclipse
  

Every 18 months, replace the UV-C Lamp.  Again, download instructions below in our RESOURCE CENTER.
