INSTALLATION PROCEDURE
The Poly-A System was developed to work with a properly operating filtration sys-
tem to provide unsurpassed water clarity. The Poly-A System consists of a feeder,
fittings and tubing along with a flow meter to regulate the flow of Poly-A Tablets
into the pool. Poly-A is a proprietary blend of water clarifiers compressed into a
convenient four ounce tablet.
Never use any other type of chemical in the VPF-20. The use of other chemicals
may lead to explosion, fire or the creation of hazardous gases, possibly leading to
personal or bodily injury. The applicability of any limited warranty either expressed
or implied is limited to the use of Vantage Poly-A Tablets in the VPF-20 feeder.
The VPF-20 is designed for use in any size pool and using a sand, diatomaceous earth or cartridge
filter media.
This feeder should be installed in a secured maintenance room or other suitable location to prevent
general public access to the feeder and associated chemicals.
Select a feeder location that has easy access for maintenance and refilling. This feeder must be
installed in an area protected from direct sunlight and rain. Tubing lengths should be kept as short
as possible. Choose an installation location that minimizes the tubing length of the feeder output.
This feeder should be installed on a flat, level surface capable of supporting its weight when full.
Exercise caution when opening or servicing the Poly-A feeder. Always shut off the pump and isola-
tion valves before opening feeder. Do not open feeder when the pump is running and the isolation
valves are open. Open air relief valve on top of tank prior to removing the lid.

RECOMMENDED INSTALLATION METHODS
Filter System information
Sand Filters
High Rate sand filters are the most common filter type used in the recreational water treatment
industry. The two important aspects of high rate filtration that must be taken into consideration when
using Poly-A Tablets are sand size and flow rate. The effective particle size of the filter sand should
range from 0.40 to 0.55 mm and the uniformity coefficient should not exceed 1.75. The flow rate
should not exceed 15 gpm per square foot. If necessary the flow rate should be reduced to 15 gpm
per square foot. If reducing the flow rate is necessary, be certain to maintain a rate regulated by
local or state regulations.
Diatomaceous Earth
There are two types of D.E filters, pressure and vacuum. Each type relies on the hydraulic place-
ment of diatomaceous earth media onto porous support septums. D.E media is composed of small
fossilized remains that act as filtering microscreens to remove insoluble particles from pool water.
Flow rates should not exceed 1.5 gpm per square foot.
Cartridge Filters
Cartridge filters are arranged in a pressure vacuum housing assembly. The cartridge is usually con-
structed of a synthetic fabric. Since cartridge filters cannot be backwashed, internal cartridges must
be physically removed and cleaned. After repeated cleaning, the cartridge may exhibit shorter run
cycles. Flow rates should not exceed 0.375 gpm per square foot.
PRESSURE-SUCTION
The pressure-suction installation is the most common used with the Vantage Poly-A feeder. The
feeder supply line (3/8" o.d. tubing) uses filtered water to supply the feeder water. The feeder outlet
line (3/8" o.d. tubing) connects the feeder effluent to the main pool suction line prior to the main cir-
culation pump.

PRESSURE-GRAVITY
A pressure gravity installation can also be used with the Vantage Poly-A Feeder. The feeder inlet
line (3/8 o.d. tubing) is connected to the filter discharge line prior to any other chemical feed line.
The feeder effluent line (3/8" o.d. tubing) is placed through a 3/4" PVC schedule 40 pipe attached to
the wall of the pump "wet well" with the end of the tube near the pump intake.
The pressure-gravity method can also ne used with vacuum sand and diatomaceous earth filter. The
feeder outlet line (3/8" o.d. tubing) is placed over the side of the vacuum filtration system. The outlet
line can be placed either above or below the water line of the vacuum filter. The outlet line must be
secured so as not to become dislodged during filter operation.

STARTUP AND ADJUSTMENT OF VPF-20
Poly-A Dosage Rates
Initial use of Poly-A Tablets may cause filter pressures to rise within a few hours of application.
Pressure differentials and flow rates will indicate the need for backwashing. It is not uncommon that
a backwash is required within hours of an initial application of Poly-A, particularly if the pool water is
cloudy. Poly-A increases the filters efficiency and more dirt and smaller particles are trapped on the
filter for removal. Shorter then normal filter cycles are typical when Poly-A is first used. As these
particles are removed through backwash or filter cleaning the filter cycles will return to normal.
Sand Filters
For sand filters, a dosage rate of 1 ounce of Poly-A per square foot of filter area ( 1 Poly-A Tablet per
4 square feet of filter area) should be used. After each backwash, follow the instructions for refilling
the feeder. Once the pool water is clear, and depending upon bather load, the application of Poly-A
following every other backwash application may be sufficient to maintain water clarity. During active
use, sand filters should be backwashed at least once a week, even if influent and effluent gauges do
not indicate a need for backwashing.
D.E. Filters
For both vacuum and pressure D.E. filters, a dosage rate of 0.08 ounces of Poly-A per square foot of
filter area (1 Poly-a Tablet per 50 square feet of filter area) should be used. After each backwash fol-
low the instructions for refilling the feeder. Once the pool water is clear, and depending upon bather
load, the application of Poly-A following every other backwash application may be sufficient to main-
tain water clarity.
Cartridge Filters
For cartridge filters a dosage rate of 0.05 ounces of Poly-A per square foot of filter area (1 Poly-A
Tablet per 80 square feet of filter area) should be used. After each backwash follow the instructions
for refilling the feeder. Once the pool water is clear, and depending upon bather load, the application
of Poly-A following every other backwash application may be sufficient to maintain water clarity.
FILLING THE FEEDER
1. Close the 1/2” isolation valves on both the inlet and outlet sides of the feeder.
2. Open the air relief vent valve on top of the feeder and the drain on the bottom of the feeder. Allow
the feeder to empty.
3. Close the drain valve.
4. Remove the feeder lid.
5. Fill the feeder with the appropriate number of Poly-A Tablets for your filter type and size from the
table below. If the the filtration system calls for more product then the feeder can hold, the prod-
uct should be dispensed, and the feeder refilled until the proper quantity of product is delivered.
6. Close the air relief valve and replace the feeder lid.
7. Test the pool water to determine the pH. The pool water must be above 7.4 pH. The ideal pH
range for product performance is 7.5 to 8.0. Adjust the pH of the pool water as necessary.
8. Open the 1/2” influent isolation valve followed by the effluent valve. Using the 1/2” effluent valve
and the flow meter, adjust the flow rate through the feeder to between 0.05 and 0.1 gpm.
9. The Poly-A feeder needs no further adjustments until it needs needs to be refilled for the next
application of tablets.
CLEANING AND MAINTENANCE
TABLET HOPPER
1. Close the inlet and outlet ball valves.
2. Open the air relief valve and drain to allow the feeder to empty before removing the lid.
3. Rinse, brush, and clean out the basin with water to remove any residue.
4. Place Poly-A Tablets in the feeder.
5. Follow the instructions for filling the feeder.
