CLEAN WATER STORE 7500-REV2.5 Air Charger Sulfur Air Filter Installation Guide

CLEAN WATER STORE 7500-REV2.5 Air Charger Sulfur Air Filter

Introduction

Thank you for purchasing a Clean Water System! With proper installation and a little routine maintenance your system will be providing chlorine free water for many years.
Please review this start‐up guide entirely before beginning to install your system, and follow the steps outlined for best results.
Minimum pressure of 30 PSI recommended.
Maximum pressure recommended 80 PSI.
For indoor installation only.
Protect from sunlight, rain, and freezing.
CARBON MEDIA CONTAINS DUST.
USE MASK TO AVOID BREATHING DUST.
OK to wet down media with spray bottle
This filter system utilizes aeration and filtration for the removal of sulfur odors. This process will leave some air in the water. The air may give the water a milky appearance and is simply excess air in the water. While a certain amount of effervescence will always be present, it may be most noticeable during the first 30 days after installation of the system.

What to Do if Your Tank is Not Level Out of the Box
Your black filter tank base is not glued to the bottom of your tank. Occasionally tank bases will become crooked during shipment. If you find that that your tank does not sit level on the floor, you can easily adjust it by holding the empty tank and knocking it on a concrete or solid floor once or twice to level it.

Pre-Installation

1. Review your packing list and make sure you have received all the parts before installation.
2. If you are going to be turning off the water to the house and you have an electric water heater, shut off the power to the water heater before beginning installation in case water heater is accidentally drained.
3. Pick a suitable location for your filter system on a dry level spot where it won’t be exposed to freezing temperatures. A minimum of 20 PSI is required. Maximum pressure is 90 PSI.
4. Get all of your plumbing parts together before beginning installation, and make sure you have received all of your packages before beginning or scheduling an installation. Installation typically takes 3 to 5 hours. However, after installation the Sediment Filter must be allowed to run through a complete backwash and rinse cycle.
5. After the system is installed and running, your water may be discolored, or full of sediment or rust, particularly if this is older or corroded piping. This typically clears up over a day or two.

Best Practices for Piping & Drain Installation

1. Make sure to connect the Inlet from your water source and outlet, following arrows on control valve. Connect the External Flow Control fitting onto the Drain line.
2. Make sure there is a ball or gate valve before and also after the filter system.
3. A hose bib (which is a faucet to which you can attach a garden hose) is strongly recommended after the Sulfur Air Filter and before the second ball valve. This makes it easy to rinse your new Sulfur Air Filter on start-up and gives you a place to test the water.
4. If you will be using copper piping, do not sweat the copper pipe directly on to the 7500- REV2.5 control valve.
5. To connect drain line to drain, use an air-gap connection, so that if your sewer or septic tank backs up, it cannot cross connect with the drain tubing.
6. The pipe connectors are 1’ male pipe thread but you can add a reducer to reduce to ¾” pipe with common pipe fittings if needed.

How the Bypass Valve Works

Turn knob so the valve is bypassed when installing.
When you go to start up system turn the bypass SLOWLY to let water in and put in service.

Installation of Your System in Copper or Metal Piping Systems

If your new filter system is to be installed in a metal (conductive) plumbing system, i.e., copper, or galvanized steel pipe, the plastic components of the system will interrupt the electrical continuity of the plumbing system.
As a result, any stray currents from improperly grounded appliances downstream or potential galvanic activity in the plumbing system can no longer ground through the contiguous metal plumbing.
Some homes may have been built in accordance with building codes, which encouraged the grounding of electrical appliances through the plumbing system.
Consequently, the installation of a bypass consisting of the same material as the existing plumbing, or a grounded “jumper wire” bridging the equipment and reestablishing the contiguous conductive nature of the plumbing system must be installed prior to your systems use.
This is simple and easy step to take if you are installing your water treatment system into copper piping.
A simple ground jumper wire with a pipe clamp can be purchased at any Home Center, or hardware store etc. for a few dollars.

How Your Sulfur Air Filter Works

The 7500-REV2.5 control valve maintains a compressed “air pocket” in the top of the tank while the system is in service.
As the water passes through the air pocket, the sulfur is oxidized and dissolved oxygen is added to the water.
The Air Charger Sulfur Filter’s catalytic activated carbon media bed then removes the sulfur and odors from the water.

Diagram of Typical Installation

Tank Assembly and Installation Instructions

1. Wrap the top of distributor tube with electrical or duct tape so that no gravel or Carbon media will go down the distributor tube when adding the media.

2. Add the filter gravel that came with your order first.

3. Next add Carbon media. The tank should be about 2/3rds full of media, do not fill more than 2/3rds, even if there is some media left over.

4. Finally add the KDF cubes. These sit on top of the catalytic carbon filter media.

5. Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube when removing cap or tape.

6. Fill tank completely with water. This will allow the Carbon Backwash Filter media to settle and reduce the need of purging the air out of the tank later. Allow Carbon to soak for at least 2 hours but 24 hours or more is OK. Carbon contains trapped air, and this will help remove trapped air.

7. Add a small amount of silicone grease to the inner O-ring, where the distribution tube goes.

8. Next, install the top screen by inserting upwards and rotating to lock in place. (This is a funnel-shaped plastic screen that locks into the bottom side of control valve.
   
   
   
   

9. Lubricate the main tank O-ring with silicone grease and screw on the 7500-REV2.5 control valve carefully. Do not use pipe-joint compound, vegetable oil, Teflon tape, or Vaseline or other greases to lubricate tank threads.

10. Connect Air Inlet Check Valve to control valve.

11. Connect bypass assembly with 1” pipe connectors to control valve.

12. Insert meter cable into meter cable port on bypass

13. Install inlet and outlet piping and hook up drain line tubing to drain.

14. If you are in earthquake zone, strap your backwash filter tank to wall with metal strapping.

15. Proceed to programming your 7500-REV2.5 control valve timer and backwash frequency.

16. IMPORTANT : you must program the time and then start a backwash and rinse. The filter system must be backwashed and rinsed several times before using. See following pages for instructions.
    
    

Programming Your Valve

How to Start a Manual Backwash: Press the Back / Regen button
Pressing “Back Regen” at any time results in an immediate manual regeneration.
Pressing and holding for 3 seconds, when system is locked, results in a delayed regeneration at the preselected time.
Extended Power Outage Indicator
If power outage exceeds 3 days, the time-of-day indicator “_” will flash 12:12. The current time of day needs to be re-set. All other set parameters remain stored in memory. The valve will resume to operate from the point of the power outage.
Lockout Function
Keypad will lock after 5 minutes without use. To access the parameter changes, press and hold “Up” and “Down” buttons simultaneously for 3 seconds to unlock.

Start the First Backwash

1. After programming, the system must be run through 2 or 3 backwash/rinse regeneration cycles to clean the new filter media.
2. Start with both bypass valves in the Bypass Position.
3. Press the BACK/REGEN button once to enter the backwashing cycle.
4. When the backwash icon is displayed, slowly open the bypass to a quarter position to make the water flow into the tank. Allow to fill slowly.
5. After all the air is out of the pipeline, open bypass valve completely and complete backwash.
6. If possible, verify that the backwash flow corresponds with the size of your system below. You can easily run the drain hose to a bucket and using a watch verify the flow rate in gallons per minute. An adequate backwash is critical to properly clean the Carbon media. Make sure you have a minimum of these flow rates. For example, if the backwash water fills a 5-gallon bucket in 1 minute, you have 5 gallons per minute (GPM).
   1.0 CF| 5 GPM
   ---|---
   1.5 CF| 5 GPM
   2.0 CF| 8 GPM
7. After the backwash, the system will automatically go into the fast rinse stage. The control valve will return to service status (indicated by the up flowing meter on the left) after the backwash and rinse are complete.
8. 8 Repeat the Regeneration (backwash and rapid rinse cycle) step 2 to 3 more times until you see clear water through the drain line or your hose bib.

Troubleshooting the 7500-REV2.5 Sulfur AIR Backwash Filter

One problem that may occur is if you do not have enough backwash flow rate to properly clean the Carbon Backwash Filter.
You can verify the backwash flow rate by running the drain line into a bucket and timing it when the 7500-REV2.5 is in Cycle 1 or backwash.
What to Do If Odor Returns
If your systems worked at first but then the odor came back, check the following:
Check odor at the hose bib directly after the filter system, which is before your household piping. If no odor is present right out of the hose bib, or if you are having odor at only one fixture in the home but not others, you should sanitize the household piping with chlorine bleach.
To Chlorinate Piping
Put Sulfur Air system on bypass.
Add 1 or 2 cups of bleach to the prefilter or add 1 or 2 cups bleach however you can. Run the water in the home until you smell bleach. Turn off water and let chlorine sit in pipes for 3 – 4 hours.
Put Sulfur Air system back in service and run water in the home.
Check to make sure the air draw is working: put into a manual regeneration and once its in the brine draw cycle, check to make sure the air inlet is sucking in air. If it is not drawing clean the brine injector throat and nozzle
