NOTE: If a Whole House Arsenic / Heavy Metals Filter is recommended and installed, arsenic and / or heavy metals analysis of the
treated water MUST be performed every six (6) months. For a lead / lag style system (two filters plumbed in series) the
treated water sample should be taken between the two filters. CSI must be provided with a copy of the analysis results with
system serial number and project name / address. Failure to comply with this requirement will exonerate CSI of all liability
and void the system warranty. For a list of recommended water laboratories in your area, please contact your state
government of residence.
WARNING: When a treated water analysis has detected a breakthrough of arsenic and / or heavy metals, the arsenic /
heavy metals media will need to be replaced immediately. Contact your installing contractor for service.
For media disposal considerations, please consult “Disposal of Titanium Oxide Media” on page 5
of these instructions.

Media Disposal Considerations
Disposal of Titanium Oxide Media
CSI Arsentic / Heavy Metals Filter Media is a titanium oxide based media that removes arsenic by adsorption to the media ma-
trix. After many bed volumes (BV) of treated water the exhausted media is removed and replaced.
Following exhaustion, the question regarding the proper disposal of spent filter media is often asked. Many applications have
determined the spent media safe for landfill disposal as a nonhazardous material. Arsenic (or”heavy metal”) laden media has
been evaluated using both the EPA TCLP and California WET methods and has been found to be nonhazardous and safe for
landfill disposal.
Because of the concern regarding disposal of spent arsenic removal media, a study was conducted by The Center for Environ-
mental Systems at Stevens Institute of Technology in Hoboken, New Jersey in conjunction with the New Jersey Department of
Environmental Protection. This study, by Jing, Liu, Patel, and Meng and published in Environmental Science and Technology,
evaluated arsenic leaching from commercially available adsorptive media. Their study found that arsenic from exhausted TiO2
based media did not exceed the TCLP concentrations that would characterize the spent media as a hazardous material. They
also found that titanium oxide media out performed iron based GFH under the more stringent requirements of the California
WET method. An additional study by Meng et. al. showed that under reducing conditions typically found in landfills, titanium
based media released significantly less arsenic than iron based media.
Typically upon exhaustion a composite sample of the media is collected and evaluated for criteria required by the regulating
authority.Since each application differs, titanium oxide media should be evaluated following all federal, state,and local regula-
tions regarding necessary approvals for landfill disposal. However, various studies have found our media to be safe for
municipal landfill disposal without any special handling considerations.

Installation Requirements
• A level floor position ahead of piping into water heater.
• Unit must be installed at least 10’ ahead of the inlet to a water heater to prevent damage due to
back-up of hot water.
• DO NOT install the unit in an area of direct sunlight or where freezing temperatures may occur!
(See Installation Diagrams for proper placement and plumbing connections.)
Installation

SIGNATURE 2 SERIES SIGNATURE 2 SERIES
Note:
• If household plumbing is galvanized and you intend to make the installation with copper (or vice versa), obtain di-electric
unions to prevent dissimilar metal corrosion.
• All plumbing lines not requiring “soft” water should be connected “upstream” of the softener, if installed. (See Typical
Installation Diagrams.)
Caution:
• If sweat soldering copper pipe (remember to always use lead free solder and flux), cover yoke and bypass valve with
wet rags to prevent heat damage to connections and control valve. If using PVC or plastic pipe, primers and solvent
cements specifically recommended for use with potable water are required.
Installation Procedure
- Water Supply Connection and Bypass Valve -
To allow for filter servicing, swimming pool filling or lawn sprinkling, a manual Bypass Valve has been installed at the
factory. The Bypass allows raw water to be manually routed around the filter.
1. Position filter at desired location for installation. If an iron / manganese/ sulfur filter and water softener is to be
installed, the iron / sulfur filter should be positioned first then the arsenic filter and then the softener. (See Installation
Diagrams.)
2. The filter material is shipped separately from the mineral tank. The tank must be loaded with material after tank has
been placed at the desired location.
A. Remove the control valve by unscrewing from the tank.
B. Use cap provided to place over top of distributor tube to prevent material from entering tube while filling.
C. Place media funnel (part # U-1006) in hole on top of tank.
D. Pour several gallons of water in the tank. (Fill tank about 1/3 full.)
E. Pour in the required filter media. No gravel is required. The required quantity of media is listed in the
filter specifications.
F. After filling the tank with media, use a garden hose or several buckets to fill the tank with water.
This will permit the media to become soaked while preparing the installation and will prevent the
control valve from being plugged with floating media on initial backwash.
G. Remove funnel and clean filter media from tank threads.
H. Remove cap from distributor tube.
I. Replace control valve on mineral tank. Do not use Teflon tape or paste on valve threads, as the valve to
tank o-ring seals this joint.
Caution: Be extremely careful to position distributor tube into control valve distributor tube pilot hole.
3. Turn OFF main water supply and OPEN nearest faucet to relieve pressure.
4. Cut main line and install appropriate elbows and extensions. Inlet and outlet connections on the control valve are 3/4"
FNPT. (1" FNPT for WFA30)
Caution: Raised arrows located on the sides of control valve body and bypass valve indicate proper direction of water
flow. Install inlet and outlet piping in direction of arrows.

- Drain Line Connection -
1. Pull out clip and remove drain line assembly located on the left side of control valve. Remove drain line hose barb and
wrap threads with Teflon tape. Reinstall drain line hose barb. Caution: Hand tighten only! Replace drain line
assembly and reinstall clip.
2. Install 1/2” I.D. drain line tubing (not included) from hose barb to an open drain. A 4” gap between end of the drain line
and the open drain is required to prevent waste water backflow. Keep the drain line as short as possible. An overhead
drain line can be used if necessary, but should discharge below the control valve. A syphon trap (taped loop) at the
outlet of the drain line is advisable to keep the drain line full and assure correct flow during backwash. Elbows or other
fittings must be kept at a bare minimum.
Note: Where the drain line is elevated above the control valve or exceeds 20 feet in length, 3/4” I.D. drain line tubing
should be used.
- Electrical Connection -
1. Connect the power supply to the control valve and plug into a 115 volt / 60 Hz receptacle.
Note: Do not plug into an outlet controlled by a wall switch or pull chain that could inadvertently be turned off.
- Pressurizing The System -
2. Slowly rotate handle of the bypass valve to the SERVICE position.
3. Open the nearest faucet to evacuate air from plumbing lines.
4. Check for leaks! If water is observed leaking from bypass, o-rings on valve body may not be seated properly.
5. After air is evacuated from plumbing lines, turn off faucet.
- Initial Control Valve Operation -
1. Advance control valve to BACKWASH (cycle 1) position and allow water to run to drain until water runs clear.
Warning: Close handle on bypass prior to selecting the backwash position. After backwash position has been
established, slightly open valve on bypass to evacuate air from the media tank. Fully open bypass valve
when all air is depleted. This procedure will prevent media form being uplifted into control valve.
2. Advance control valve to RAPID RINSE (cycle 3) position and allow water to run to drain for 3 to 4 minutes.
3. Advance control valve to SERVICE (cycle 0) position.

Normal Operation
1. Home Display
a. Alternates between the display of Time of Day and Number of Days until the Next Backwash.
- Days Remaining until the Next Backwash will count down from the entered value until it reaches 1 day
remaining.
- A Backwash Cycle will then be initiated at the next designated regeneration time.
2. Battery Back-Up (Uses a standard 9-volt alkaline battery, not included.)
Features of Battery Back-Up:
• During power failures, the battery will maintain the time of day as long as the battery has power. The
display is turned off to conserve battery power during this time. To confirm that the battery is working,
press either button and the display will turn on for five (5) seconds.
• If power failure occurs while system is backwashing, the Signature 2 will motor to a shut off position to
prevent constant flow to drain. Depending upon system pressure and other factors, it is possible to
observe a reduced flow to drain during this step. After Power is restored, the Signature 2 will return and
finish the cycle where it left off prior to the power interruption.
• When used without battery back-up, during a power failure, the unit stops at its current point in the
backwashing position and then restarts at that point when the power is restored. The time will be offset
by the increment of time the unit was without power, so it is necessary to reset the time of day on the
unit. No other system will be affected.
