Media loading or replacement procedure

Media loading or replacement for water softeners or filters is sometimes required for units in the field. Replacement of media is relatively simple, if the following procedure is followed:

Replacement of Media Simplex Unit
Open bypass valve and close inlet/outlet isolation valves. Duplex Unit - Close inlet/outlet isolation valve of unit to be rebedded. Manually turn timer dial to backwash position (Manual Regeneration) to relieve vessel pressure. Unplug electrical connection of unit. Disconnect inlet, outlet, drain, and brine lines. Unscrew valve head from tank. Remove distribution tube from tank and visually inspect for any damage or wear and replace if necessary. Empty media into a vessel with resin trap/strainer, to retain the resin/gravel and allowing water to drain. Dispose of used media. Relocate softener tank in original location.

Loading of Media
Install distribution tube in mineral tank. Place a cap or tape over the open end of distributor to prevent any media from entering. Fill tank approximately one-third with water to act as a buffer. Slowly pour the required amount of media in each vessel: Gravel to be loaded first. Resin to be loaded second. Clean top of tank and tank threads of any resin or gravel. remove cap or tape from distribution tube and clean. Visually check and clean valve and distribution “O” Ring of any foreign matter and lubricate with silicone or soap.

NOTE: Do not use Vaseline or grease. Locate control valve on tank making certain riser tube is centered. Tighten valve to tank. Reposition and level tank if necessary to assure proper alignment. Connect inlet, outlet, drain, and brine connections
