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 (Item A) from
the fiberglass tank. Once this has been done, remove the distributor tube (Item B). Then you can
remove the filter media and the gravel from the tank. The quickest way to do this is by simply
tipping the tank upside down into a large drum or pail. 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 (Item B) 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 medium
gravel (Item D) 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.
Finally pour the larger bag(s) of media into the tank
For multi-media units only. These units have to be loaded in the following order:
1. Medium gravel (1/4 x 1/8)
2. Media
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 onto 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.
Maintenance Instructions
Maintenance of your new water filter requires very little time or effort but it is essential. Regular maintenance will ensure many years
of efficient and trouble free operation.
Care of All Water Filters
To retain the attractive appearance of your new water filter, clean occasionally with a mild soap solution. Do not use abrasive cleaners,
ammonia or solvents. Never subject your filter to freezing or to water temperatures above 120°F.
Replacing Media Bed
next-Sand Filter - under normal operating conditions, the media should never need to be replaced. If you experience pressure loss and
cannot correct it with a manual regeneration, your media bed may need replacing - contact your dealer
