Please Read Manual First
Before you operate your Aquatek Iron Filter, read this manual to become familiar with the
device and its capabilities.
Installation or maintenance done on this system by an untrained service person can
cause major damage to equipment or property damage. Not adhering to the recom-
mended service/maintenance can cause damage to equipment or property damage. It
is important to maintain your sulfur and iron filter. To properly maintain your system have
a water technician change the filter media when necessary. (Check with your dealer.) If
your filter media is not working properly, or is not replaced frequently enough, it has po-
tential to grow bacteria that can end up in your water system. A water technician can tell
you how often the filter media needs replacing.
This manual is intended to be a practical reference guide. It contains information about
operating this water filtering system—including installation and start-up instruction for the
installer and programming, regenerations, settings and troubleshooting for the home-
owner. The Sulfur and Iron Water Filter is designed for long-term use. To determine when
to change the filter media, contact your dealer. Every system encounters different water
conditions therefore every filtration system will have different timetables for replacing the
filter media. Make sure you have a water technician change your filter media and periodi-
cally test for effectiveness.
Introduction
1Zeolite
Background
Zeolite filter media offers advantages over conventional sand, sand & anthracite or multimedia for gravity flow or pres-
sure vessel beds. Historically, natural zeolite mineral deposits were discovered in the 1950’s and zeolite has been quary,
mined, crushed, air-dying and sieve sized to produce commercial products for >30 yrs. Natural zeolite (Clinoptilolite) is
crystalline, aluminum oxide/silicn oxide classified as a crystalline, molecular sieve, mineral consisting of hydrated Ca2
(Na2 or K2) Al8 Si28O72•24 H2O. Most zeolite deposits are low quality and can’t be used as molecular sieve beds or wa-
ter filtration media. Zeolite has been used for water softening and to remove NH-4 ion using slow flow rates (1-2 gpm/ft2
) and Na-ion regeneration cycles. Since 1985 numerous technical and engineering studies have demonstrated the utility
of zeolite mineral as an effective water filter media.
Zeolite Filter Media
Zeolite Filter Granules are a high quality, granular, filter media that achieves superior filtration & solids loading com-
pared to conventional filter media. The zeolite media is from a unique, mineral deposit in the western USA having high
porosity, hardness, high surface area (~28m2 /gm) and surface, micromineral, projections that make it an ideal water
filtration media (fig 2 & 3).. The 14 x 40 mesh
filter media has a dry bulk wt.55 lb/ft3 & is attrition resistant. The zeolite mineral is classified under 21CFR Part 182.2729 &
40 CFR Part 180. as GRAS (Generally Recognized As Safe) and is NSF Standard 61 Listed.

About Your Filter
How Does my Sulfur and Iron Filter Work?
This filter uses a special blend of calcium, magnesium oxide
and sand that is highly effective for removal of hydrogen sul-
fide and iron. The filter uses an air chamber within the tank to
capture and oxidize the elements and then filter them through
the media bed. An automatic backwashing system will clean
the media of the sulfur and iron leaving the system clean, and
the water you drink odor free.
A Control Valve
B Mineral Tank All Aquatek Iron Filters are comprised of two primary
components: (A) Control Valve, (B) Mineral Tank.
A. Control Valve: Your control valve automatically
performs the 3 primary operations which are com-
monly referred to as cycles. These operations/cycles
are:
1. Pre-Treatment Oxidation: Air is injected into the
mineral tank which causes contaminants in the
water to precipitate and settle out. Precipitated
contaminants are much larger and clump to-
gether so they can be removed through filtration.
2. Service / Filtration: The oxidized water is now
flushed through the media bed comprised of Ze-
oLite1(see pg 4) and gravel underbedding which
mechanically strains the contaminants like iron,
manganese, & hydrogen sulfide.
3. Backwash: Once the media bed has reached its
predetermined limit of filtration it cleans and re-
plenishes itself through backwashing. Backwash-
ing is a forceful flush that removes the filtered
contaminants and then flushes then down the
drain.
B. The Mineral Tank: The mineral tank contains the
filtration media and is where the the treatment of
the water takes place during the 3 stages mentioned
above.

Installation Guide
Pre-Installation Checklist
1. A standard electrical outlet (120V/160Hz) must be located within 12’ of installation site.
2. A functioning floor drain, washer sand pipe or suitable location for waste water discharge must be located with-
in 20’ of installation site.
a. All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain line should
be a minimum of 1/2”. Backwash flow rates in excess of 7 gpm or length in excess of 20’ require 3/4” drain line.
3. It is recommended a working pressure reducing valve be installed on the inlet water line that supplies the water
filter
4. Note: The warranty is void if the system is exposed to water pressure in excess of 100 psi and/or water tem-
peratures in excess of 95° F
5. Important: Protect your Fitler and the entire drainline from freezing temperatures. The temperature at the loca-
tion of the system should never be below 40° F
WARNING! DANGER: If your unit should freeze, do not attempt
to disassemble it. Call us first 877-414-PURE
Installation
1. Floor Space: Make sure the floor space that has been selected to install the water filter is clean and
on a level surface. In some cases, your media may be shipped seperatelty. Place media Tank in rela-
tive position of end install, and see “Media Fill/Replacement” on page 8.
2. Leveling the System: Mineral tanks are fitted with an adjustable leveling base, if tank is not vertical/
straight lift tank 1-3 inches off the floor and gently release tank back on to the floor (repeat until stright
up and down).
3. Connection Kit: The standard connection kit supplied with the water softener will be a 1” plastic el-
bow connection kit. (See Figure 1) Other connection kits are available.
4. Plumbing Preparations: Unscrew the two plastic nuts (#1) and pull on the two brass connectors
(#4) to remove them from the bypass assembly. Next remove the white plastic rings (#2) and the
O-rings. (#3) (See Figure 2)
• Solder at least 6” of pipe to the brass connectors before reassembly. (See Figure 2)
• After soldering is complete, cool the pipe and connectors. Slide the plastic nuts (#1) over the brass connectors (#4). Place
the white plastic split rings (#2) into the grooves closest to the end of the brass connectors (#4). Reassembly the connection
kit onto the bypass assembly.
Warning: When assembling the installation-fitting package (inlet and outlet), connect the fitting to the plumbing system first
and then attach the nut, split ring and O-ring. Heat from soldering or sol- vent cements may damage the nut, split ring or o-
ring. Solder joints should be cool and solvent cements should be set before installing the nut, split ring and O-ring. Avoid getting
primer and solvent cement on any part of the O- rings, split rings, bypass valve or control valve.
5. Plumbing: When connecting the water filter to the existing plumbing, make sure the inlet water is
connected to the inlet of the filter. Arrows on the valve body indicate direction of flow. Make sure the
bypass valves are in the correct position See Figure 3. An internal check valve is supplied with the sys-
tem and has already been installed in the inlet of the control valve to ensure that the air charge in the
top of the tank does not escape backwards out the inlet.
Note: All plumbing should be done in accordance with local plumbing codes.
Warning: The control valve, fittings and/or bypass are designed to accommodate minor plumbing mis-aligments
but are not designed to support the weight of a system or the plumbing.

6. Locate Polytube Insert: Now that the water softener is connected to the existing plumbing, the drain
line may be connected. First, locate and remove the polytube insert (#2) from the gray cable on the
left side of the control valve. (See Figure 4)
7. Connecting the Drain Line: Slide plastic nut (#3) over the permanent drain tubing and place the
polytube insert (#2) into the end of the drain tubing. Insert the drain tubing into the drain elbow fitting
(#4) and tighten plastic nut (#3) hand-tight plus 1/2 turn with pliers. Caution: Do Not Over-tighten.
(See Figure 4)
8. Drain Line Specs: If the distance from the water filter to the drain is greater than 20’ the drain line
size must be increased to 3/4”. The threads on the drain elbow fitting are 3/4” male NPT and can be
used in lieu of the 1/2” plastic nut and insert. If the drain line must run overhead, the maximum height
of the drain line should not exceed 8’ above the top of the water softener.
9. Air Gap: The drain line must have an approved air gap to prevent the possibility of a cross connec-
tion to the sewer. (See Figure 5)
10. IMPORTANT: Special precautions must be made when connecting the drainline. During backwash,
high volumes of air and water escape rapidly, causing a flexible drain line to whip and thrash. Rigid
drain piping is highly recommended.

These instructions are to help guide you through the steps for initial installation or replacement of
the media in your filter or softener. Please check to ensure that all the parts have been included
by reviewing the labels that are attached to the filter (e.g. xxx bed - container 1 of 3, 2
of 3, 3 of 3). Container may contain more than one media. lf you have any questions regarding
the installation or replacement of your media bed, please contact your local dealer for assistance.
Fig. 1 - The riser
(distributor) remains
inside the tank seated
in the depression at
the bottom. The riser
should be capped to
prevent resin beads
from getting inside.
Fig. 2 - Fill support
bed first (if supplied)
Fig. 3 - The media will
not always spill down
inside the tank and
may need to be swept
inside
1. Loading the Media Pak
Place the distributor tube into the media tank and
plug the end of the distributor tube with a tape to
prevent media from entering it. Make sure that
distributor tube is inside the tank and seated in a
depression at the bottom of the tank. (If replacing the
media. inspect the distributor for any damage to the
slots in the cone or plugging - clean if necessary.)
Plug tube with a tape
Remove after media
is loaded.
Plug the media tube with tape to prevent the media
from getting inside the tube. Place the media into
the tank in the order indicated on the next page for
the type of unit that matches yours. The large funnel
(supplied) makes filling the tank easier and heater.
(Or an empty 1 gallon or 4 liter container with the
bottom cutout makes a good funnel.) Fill support bed
(if supplied) first. During the filling process, ensure
the distributor tube stays on the bottom of the tank,
reasonably centered. Remove the
tape from the distributor once media
is loaded. Whenever possible, fill the
tank outdoors to avoid problems with
dust. lf filling indoors, a dust mask
should be worn.
2. Placing the Unit in Service
Once the tank is filled, remove the cover from the
distributor and clean off the top of the tank. Place
the control valve onto the tank, ensuring the
distributor fits into the valve properly. Tighten the
valve onto the tank using moderate force. Applying
some household liquid soap to the main seal
O-ring will ease assembly. Attach the plumbing to
the inlet and outlet of the valve as necessary
Follow the installation and operating instructions
for system start-up found in your Owners Manual
or slowly fill the tank in the backwash position and
allow it to flush the air and fine particles down the
drain until the drain water appears clear (about 20
minutes). Once the drain runs clear, plug in the
electrical cord, open the inlet valve fully and allow
the valve to finish its cycle. Check for any leaks
and reset the time of day on your controller.
3. Depressurizing the Unit*
The first step is to loosen the bed and depressurize
the unit. Place the unit into the backwash position
and keep it there by unplugging the unit from the
power supply. Allow it to backwash for several
minutes to loosen the bed. To depressurize, simply
shut off the water supply to the unit either at the
main or use the bypass to the unit.
4. Removal of Old Media*
Next remove the control valve and empty the tank.
You may have to disconnect plumbing from the
inlet and out let of the valve. depending on the type
of valve your filter or softener has. insert a piece of
1/2" flexible hose into the distributor and siphon the
water into the drain. Remove the distributor tube
from the tank. Flush out all the contents into a
large pail or garbage can by elevating the tank as
required (dictated by container used to hold old
media). Lay the tank on its side and insert a
garden hose into the tank. Make sure the tank is
completely empty before proceeding.

Bypassing Filter
Bypassing the filter will reroute the unfiltered water to the fixtures in the house. In effect, your water is no lon-
ger filtered. Bypassing the filter is only necessary to isolate the filter in case of contamination, repairs and to
stop leaks.
Step 1:
Locate the bypass valve on your filter. It will have two red handles in the shape of arrows.
The handle on the left will be facing AWAY from the unit. The red handle on the right will
be facing TOWARD the unit. This indicates that the unit is in the SERVICE MODE.
Step 2:
To set the unit in the BYPASS MODE, turn both red handles so that they are facing each
other. This prevents unfiltered water from entering the unit and reroutes it directly to the
fixtures in the house.
Bypassing the filter will allow unfiltered water into your home. Bypassing is
for emergencies or service only!
