3E. WINTERIZING
If the pool will be shutting down for the winter months and the DEL AOP will remain exposed to freezing temperatures, the
unit must be drained to prevent freeze damage. Follow the steps below to drain.
1. If mounted below the water level, bypass valves must all be CLOSED to prevent excess water from draining through the
unit.
2. Open the enclosure door.
3. Locate the 1” NPT drain plug (Refer to Figure 9) and remove to drain the remaining water.
4. Water will drain through holes in the bottom of the unit. Alternatively a connection can be made at the 1” NPT drain to
run water away from the unit.
5. Allow all the water to drain before threading the plug back into the plumbing. Be sure to clean any excess water that
may have collected in the bottom of the unit.
