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
NF -
the media bed in a neutralizing filter is slowly dissolved and has to be replaced. The frequency of replacement varies,
depending on water quality – consult your dealer to determine the expected life of your media bed.
ACF -
under normal operating conditions the effective life of the filter media is approximately one to three years depending on
the water quality, after which, taste and odor problems may return. When this happens contact your dealer for a replacement
media bed.
MMF -
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.
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 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
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. The top of this tube
should be plugged with a rag or cork to prevent media from entering. Pour the bag of coarse
gravel (Item E) into the tank, then pour the bag of fine 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. Coarse gravel (1/2 x 1/4)
4. Fine garnet (30 x 40)
2. Fine gravel (1/8 x 1/16)
5. Fine filter sand (.45 x .55)
3. Coarse garnet (8 x 12)
6. Anthrafilt
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 outlets 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 (Item F). 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.
