FILTER INSTRUCTIONS
These instructions cover fully automatic filters. Read
thoroughly before proceeding with the installation. Check to
be sure water is available in sufficient volume and pressure
to adequately backwash the equipment at the specified rate.
When higher service flow rates are required or water for
backwash is limited, two units should be installed in parallel.
Such an installation doubles the service flow rate without
increasing the backwash requirement. Naturally, they should
be set to backwash at different times - at least two hours
apart.
Filter Operation - During “Service” the water flows down
through the mineral bed and out to service lines. Collected
turbidity and sediment must be regularly removed from a
filter by reversing the flow of water through the filter and
running to drain. Called “backwashing”, and lasting 15
minutes, this process expands the mineral bed, freeing the
turbidity - which is then washed out to drain.
Normally, the units should be set to backwash twice every
12 days. Where conditions are extreme a more frequent
backwash schedule will be required to assure the
maintenance of a clean filter bed.
A 46 minute setting period follows the backwashing where
no flow to drain will be observed. Then a down flow rinse to
drain follows to purge untreated water from bottom of filter
bed and to settle the bed before returning to service.
During backwashing and rinsing, untreated water is
by-passed to the service lines so that uninterrupted water
service is maintained.
1. UNPACKING
Check packing list located on outside of tank carton against
cartons received. The large carton contains the filter tank,
main control valve and underbed gravel. Filter mineral is
available and is packaged separately.
2. LOCATION
For complete customer satisfaction, all water in the home
should be filtered with the exception of the outside faucets.
Select a location near the water service inlet and near a
floor drain. Be certain that all sides of the filter are easily
accessible for service and maintenance. On a private water
system, locate filter as shown in Diagram A. An uninterrupted
115 volt circuit must be nearby for automatic units.
3. MINERAL
The tank must be loaded with mineral after the tank has
been placed at the desired location. Remove the valve by
unscrewing from the mineral tank. Leave distributor tube in
the tank while filling. Cover top of distributor tube to prevent
mineral from entering tube while filling. Place funnel in hole.
Pour several gallons of water in the tank then pour in the
filter mineral.
The required quantity of each type of filter mineral is shown
under specifications, Figure 1. When filled, the tank should
be approximately two thirds full. As a check, measure
distance from top of filling port to the mineral bed surface.
This distance should be approximately 18 inches.
Fill tank with water by using a garden hose or several
buckets of fresh water. This will permit the filtering material
to become soaked while preparing the installation and will
prevent the control valve from being plugged with floating
mineral on initial backwash. Remove funnel and the plastic
plug from the distributor tube. Replace the valve, while
being careful to position the distributor tube into the
distributor pilot tube in the adapter.
