How do I register for the warranty with my new Pentair product?

Effective October 1, 2013, Pentair Aquatic Systems’ Limited Warranty on its core products of pumps, filters, heaters/heat pumps, automation, lights, sanitizers, water features, and maintenance products will decrease to 60 days UNLESS PROFESSIONALLY INSTALLED by a QUALIFIED INSTALLER on residential installations.
Bundled equipment purchases from 3 or more different product groups (inground pump, filter, heater, heat pump, control system, automatic cleaner, lighting, or salt chlorinator) purchased on the same invoice and professionally installed at the same time, will receive extended coverage of 3-years under our limited warranty terms. You’ll note that pool cleaners, maintenance equipment, and aboveground systems are categories where the warranty period is not predicated by professional installation because of the ease of self-installation by the pool owner.
Pool owners will be required to submit an original sales receipt along with a qualified installer’s invoice indicating the installation date as proof of professional installation in order to register their products and obtain the extended warranty terms.
Below are the warranty periods by product line if professionally installed only. If not professionally installed the warranty is 60 days from date of purchase.
I waited several months to write a review on this filter to make sure I gave it time to form a fair opinion. For the most part, it's really a great product and an even better design. I love that I was able to plumb directly into the filter and not use a valve - that saved me over $100! The filter is very easy to clean and the replacement cartridges are very affordable, when the time comes to purchase them. The only reason I gave the Quad DE filter 4 stars instead of 5 is because the price is a little on the high side.
