INSTRUCTIONS FOR REFILLING THE WHOLE HOUSE WATER FILTER WH-200B

Prepare the area near the filter for working.  You will detach the filter from the system, lay it on its side to dump the old media.  You will rinse the inside of the tank and the Riser Tube Assembly.  You will refill the tank using approximately ten pounds of clean quarter-inch gravel and the new copper-zinc filtration media.  You will need a tarp onto which to dump the used filter media and/or a container for its desposal.

    The WH-200B consists of two main parts:
                The backwash head (which sits on top)
                The filter housing (the large tank)

     The backwash head is where the water enters and leaves the filter.  On the back of the filter you will see the brass by-pass valve which has three pipe connections.  One is the water inlet - arrow points toward the filter.  The second is the water outlet - arrow points away from the filter.  This is the connection that supplies your house.  The third connection is the drainline.
     You will see a red, vinyl-covered handle on the bypass valve.  It can be in one of two positions;  "Service," which sends the water through the filter media to your house during normal operation, and "Backwash."
     When you are ready to change the filter media, turn the by-pass handle to the "Backwash" position. No water will enter the filter.
     On either side of the brass bypass valve where the brass connects to the plastic part of the backwashing head there are silver brackets with screws in the middle.  Loosen the screws so the brackets slide away from the body.
     If the drainline connection is made to a simple hose, simply unscrew the hose and proceed.  If the drainline is connected to hard pipe (either plastic or copper) the pipe will have to be cut unless another means of detaching the pipe has been provided.  Once the pipe is cut, or the hose removed, you may pull the backwash head (and filter tank) away from the bypass valve.
     With the unit standing by itself in a clear area, unscrew the backwash head from the filter housing body by turning the backwash head counter-clockwise - like unscrewing the lid of a jar.  Lift the backwash head off and set it aside, out of the way.
    Looking inside the filter housing you will see a tube in the middle of the opening.  This is the Riser Tube.  It extends to the bottom of the filter tank.  At the bottom end of the Riser Tube is the Distributor Basket, a conical shaped tube with slots that guide the water.  You will reuse this tube with the new material, so take care not to damage it in the next steps.
     Carefully lay the filter tank on its side and begin dumping the used filter media out.  Remove the Riser Tube as soon as you can, but don't force it.
     Once the Riser Tube has been removed, finish dumping as much of the used filtration media as you can, the rinse the inside of the filter tank and the Riser Tube assembly thoroughly.  It's best to use a water hose for rinsing.
     After the tank is clean, stand it back up and reinsert the Riser Tube.
     Pour in enough of the quarter-inch gravel to cover the top of the distributor basket.
     Pour in the new copper-zinc filtration media.
     Reattach the backwashing head, making sure the Riser Tube fits into the center hole of the backwashing head.  Screw it down tight and secure.
     Move the assemble unit back into position and reattach the backwashing head to the bypass valve.
     Reattach the drainline.
     Make sure all fittings are secure.
     Put the unit in the backwash mode by turning the dial on the face of the backwash head to the "Backwash" position (clockwise).  Use the handle on the bypass valve to change the pointer to the "Service" position.
     You will hear water running into the tank and then out the drainline.  This is normal.
     After running the water for two or three minutes, turn the dial on the backwashing head clockwise to the "Service" position (nine o'clock).
    Your unit is now back in normal operation.  Congratulations!
