WCFM500K Central Whole House
Water Filtration System Operation
(1) Product Functions and Features
The Central Whole House Water Filtration System is designed for use whenever iron is problematic
in the water supply. When water enters the Central Whole House Water Filtration System, it passes
through a pocket of compressed air that incorporates oxygen. The water then passes through a filter
bed, creating a reaction that separates the iron particles from the water. The Central Whole House
Water Filtration System catches the iron particles, leaving iron-free water for use in all water
applications. The Central Whole House Water Filtration System refreshes itself every three days in
a process that washes the iron out from the filter, down the drain. It refills the compressed air
pocket at a scheduled time (normally 12:00 AM).
• Regeneration Cycle (59 minutes)
Backwash (14 minutes): During this cycle, the water carrying the iron/manganese runs to the
drain. Untreated water is available during regeneration.
Air Recharge (40 minutes): During this cycle, the unit empties water to drain and is recharged
with air. The sound of air being recharged will be heard. Air bubbles should go down to the
drain before proceeding to the next step. Adjust cycle time if necessary.
Rapid Rinse (5 minutes): During this cycle, water enters the tank, compressing the air into a
pocket at the top of the tank.
