December 2017:  DEL renamed their Solar Eclipse to DEL AOP 50 (and the smaller version DEL AOP 25)  If you have a Solar Eclipse, this lamp will work for you!

Maintaining your DEL Ozone AOP 50/Solar Eclipse is important for your pool water, and for the lifespan of the system.  Every 18 months (1.5 years) replace the AOP 50/Solar Eclipse's UV Germicidal Lamps.

Additionally, when the Quartz Tubes which house the UV Lamps becomes dirty, the ability to transmit UV rays from the Lamp are diminished.  Every 6 months, clean both UV Lamps' Quartz Tubes.  Download instructions below in our RESOURCE CENTER.

There are several part numbers out there, so to clarify which one your manual shows vs. which one you actually need:

1. 9-1197-01 UV Lamp is no longer available.  This was the first lamp used, and was replaced with the 9-1266-01 lamp below
   
2. 9-1265-01 UV Lamp is no longer available.  This was the second lamp used, and was used in SEC-100-26 model.  DEL recently consolidated all the parts needed for all models and now sells ONE SKU to fit all (see 9-1266-01 below!)
   
3. 9-1266-01 is the current model and is used for ALL AOP 50 and SOLAR ECLIPSE MODELS (including SEC-100-26 and SEC-110-26)
   

ENVIRONMENTAL NOTICE:  Hg-Lamp CONTAINS MERCURY.  Manage in accordance with disposal laws.  See www.lamprecycle.org.  Due to stricter laws not allowing UV bulbs to ship via US Postal Service, they will be shipped using UPS.
