The Sunflower II
Zinc Anode

All the same features of the Original SunFlower Zinc Anode

If the cooler pan is made of fiberglass or plastic, the patented Sunflower II should be installed. It does not have to be grounded to the cabinet like the Sunflower I.

The Sunflower II comes grounded to a strip of copper and is laid in the pan instead of being grounded to the pan. The copper corrodes the zinc, which make the anti-fungal zinc oxide salts.

In the fall or in the spring, the zinc salts can be vacuumed with a "shop vac" and the anode replaced if it has "dissolved." The pads can be inspected and replaced, if necessary.
