SECTION 1 General Information 1A. Description The DEL Ozone ABG 25 (Part numbers EC-AG1U and EC-AG2U) described in this manual is designed to provide the benefits of ozonated water in an environmentally safe and effective manner. The high quality, specially engineered components ensure efficient ozone output and reliable performance.
SECTION 2 Installation Figure 1: Wall Mount 2A. Location The Ozone Generator units are designed for wall mounting. See Figure 1. Mount in a clean, protected area, either indoors or outdoors (preferably out of direct sunlight). Locate out of reach of sprinklers or drainage spouts.
SECTION 2 Installation 2C. Electrical 2C-1. Main Power Connect the Ozone Generator to the pool timing clock so that the Ozone Generator operates simultaneously with the pool pump.
