Potassium Permanganate
Potassium permanganate refills in 10 lb. (4.5 kg) packages can be obtained from your dealer. Exercise care when handling potassium
permanganate. Wear rubber gloves and avoid contact with skin or clothing. Avoid inhaling. Clean any spillage immediately. Stains can
be cleaned with a mild solution of sodium hydrosulfite (Pro-Rust Out).
INSTALLATION & REPLACEMENT OF FILTER MEDIA PAK
Check to ensure all media parts are received.
The first step in replacing the media bed is to shut off the water supply to the filter. Then place the unit into the backwash position to
release any pressure in the lines. At this point, you must disconnect the plumbing from the inlet and outlet. Then unscrew the control
valve from the fiberglass tank. Once this has been done, remove the distributor tube. Then you can remove the filter media and two
types of gravel from the tank. The quickest way to do this is by simply tipping the tank upside down into a large drum or pails. The tank
must be rinsed out completely and have no media or gravel left in it at all.
Loading the Media-Pak
Place the distributor tube back down the center of the tank. NOTE: The top of this tube
should be plugged with a rag or cork to prevent media from entering. Pour the bag of
coarse gravel into the tank, then pour the bag of fine gravel into the tank.
It is important that the distributor tube is not moved or pulled out as it would not
be possible to put it down to the bottom of the tank once gravel or media are in the
tank.
Once this is done, the rag or cork should be removed from the distributor tube. Clean off
the top of the tank. Finally, place the control valve on the tank and on to the distributor
tube. Tighten the control valve onto the tank. Connect or reconnect the inlet and outlet
and drain. The control valve should be in the backwash position. Slowly open the inlet
valve water supply and slowly fill the filter tank until water appears at the open drain line.
Return the control to the service position and shut the inlet off for approximately one hour
to allow the media to soak in the water.
After one hour, turn inlet water on slowly and place the control into the backwash position
and plug the unit’s electrical cord into a constant power source. Let the unit continue
through its regeneration cycle automatically.
The regeneration is necessary so all media fines are backwashed down the drain to
ensure clean filtered water. After this media has been replaced, it may be necessary to
reset the present time of day on the control valve timer as it will have been unplugged for
some time.
Refilling the Potassium Feeder
The feeder container must be refilled on a regular basis. If it is not, the media bed can become stripped and therefore will require
replacement. Make sure the filter is not in a regeneration cycle when refilling the container.
It is recommended that the injector be removed, checked and cleaned each time the container is refilled.
Refilling of the container is to be done by the local dealer or the homeowner.
Fill the container with dry granular potassium permanganate and install a new filter pad periodically.
USE CAUTION WHEN REFILLING TO AVOID SPLASHING OF THE CHEMICAL.
