WS1 Nitrate Filter Installation & Start-Up Guide | Manualzz
 WS1 Nitrate Filter Installation & Start‐Up Guide Thank you for purchasing a Clean Water System! With proper installation and a little routine maintenance your system will be providing soft water for many years. Your new system comes with a printed Clack Service manual, which along with this start‐up guide will help guide you in the installation and start‐up of your new system. The Clack service manual covers other types of systems as well such as backwashing filters, so there may be information in your manual that does not pertain to your system. You can also find a summary programming card located inside the front cover of the Clack WS1 control valve. Review this card for basic programming steps. Please review this start‐up guide entirely before beginning to install your system and follow the steps outlined for best results. TEST YOUR WATER REGULARLY TO INSURE THAT THE SETTINGS ARE CORRECT AND YOUR SYSTEM IS FILTERING THE NITRATE TO A SAFE LEVEL. YOUR NITRATE LEVELS MAY VARY SEASONALLY IN YOUR WELL WATER. NITRATE IS ODORLESS AND TASTELESS. WATER HIGH IN NITRATE IS ESPECIALLY DANGEROUS FOR INFANTS AND FETUS. 2806‐C Soquel Ave Santa Cruz CA 95062 For assistance call: 1‐831‐462‐8500 Email us: [email protected] More information online: www.cleanwaterstore.com Clack WS1 Nitrate Filter Installation Guide Pre‐Installation 1. Review your packing list and make sure you have received all the parts before beginning 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 accidentially 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. Installation typically takes 3 to 5 hours. However after installation the WS1 Nitrate Filter must be allowed to run through a complete backwash and rinse cycle (also called ‘regeneration’). This takes about 90 minutes. 5. After the system is installed and running, your water may be discolored, or full of sediment or rust, if you have older piping that has been exposed to sediment, iron or manganese for some time. Typically this clears up over a day or two, but can persist for weeks if the pipe is old galvanized iron pipe that is corroded. Best Practices for Piping & Drain Installation 1. The Nitrate Filter is installed after the pressure tank on well water systems. 2. Make sure to connect the inlet pipe to the WS1 Nitrate Filter inlet and the outlet to the outlet You can see the in and out arrows on the bypass valve which is where the pipes are connected. 3. Make sure there is a working gate or ball valve before the Nitrate Filter and also one after as shown in the diagram. If you are installing multiple filter systems (such as iron filter then Nitrate Filter) you do not need a valve in between each system. The pressure gauges are optional and not necessary but a hose bib (which is a faucet that you can attach a garden hose to) is strongly recommended after the Nitrate Filter before the second ball valve. This makes it easy to rinse your new Nitrate Filter on start‐up and gives you a place to test the water before it enters your household plumbing. 4. If you will be using copper piping, do not sweat the copper pipe directly to the plastic bypass valve. Avoid heating up the bypass valve with the torch. Clack WS1 Nitrate Filter Installation Guide 5. You do not need unions to install your Nitrate Filter. If you need to remove it, the Clack WS1 Nitrate Filter has union couplings on the bypass valve that make it easy to put the Nitrate Filter on by‐pass and remove the filter system from the piping. 6. The drain line tubing (not supplied) is connected to a drain from the drain outlet using flexible ½” ID tubing. Note that the drain can run up above the WS1 Nitrate Filter and into a drain, it does not have to drain down, as the filter backwashes under line pressure from your well pump. Most plumbing codes require an air‐gap connection, so that if your sewer or septic tank backs up, it cannot cross connect with the drain tubing. 7. Usually you do not want to water the garden or irrigate your landscaping with softened water. This will require more salt than usual to be used and in some cases the sodium can build‐up in the soil causing some problems to sensitive plants. It is often not difficult to run hard water (not‐softened lines) to the irrigation thereby bypassing the Nitrate Filter. If you do want to irrigate with soft water we recommend you use potassium chloride salt (widely available) instead of regular sodium chloride (Nitrate Filter rock salt). Any type of salt though can be used in the Nitrate Filter. Clack WS1 Tannin Control Clack WS1 Nitrate Filter Installation Guide Installation Instructions 1. Unscrew by hand the entire Clack WS1 control valve from top of tank if it was shipped screwed on. Place distributor tube in tank if not already inside tank. If not already done, make sure blue cap is on top of distributor tube, or wrap the top of distributor tube with electrical or duct tape. The idea is you do not want gravel or media to go down the distributor tube. Fig 3 Filter diagram showing cut‐away of media for a nitrate or softener Adding Media & Installation Instructions 1. Unscrew by hand the Clack WS1 control valve from top of the tanks if it was shipped screwed on. Place distributor tubes in tank if not already inside tanks. If not already done, make sure blue cap is on top of distributor tube, or wrap the top of distributor tube with electrical or duct tape. The idea is you do not want gravel or resin to go down the distributor tube when you are adding media. 2. Add filter gravel supplied first, using the funnel sent with the Nitrate Filter. 3. Next add Nitrate Filter resin media. Tank will be approximately 2/3 to the 3/4 full. 4. Remove cap or tape from top of distributor tube. Be careful not to pull up distributor tube when removing cap or tape. Clack WS1 Nitrate Filter Installation Guide 5. If possible at this point, fill tank completely with water. This will allow the Nitrate Filter resin to settle and eliminate the need of “purging” the air out of the tank later. 6. Add a small amount of vegetable cooking oil to the tank threads and screw on the WS1 control valve carefully. Alternatively you can use silicone grease, but do not use pipe‐joint compound, Teflon tape, or Vaseline or other petroleum greases to lubricate tank threads. 7. See how the piping connects to the bypass valve. There are in and out arrows on the bypass valve for the inlet and outlet pipe. Install inlet and outlet piping, drain tubing and brine line tubing. The brine line tube is included and is shipped inside the brine tank. 8. Note that the over‐flow fitting on the side of the brine tank does not need to be connected, unless the Nitrate Filter is installed in a closet or somewhere where overflowing salt water could cause a problem. Water rarely overflows the brine tank however. 9. Add approximately 5 gallons of water to brine tank, then fill brine tank with salt, about 300 lbs, or 6 50‐lb bags. It is OK to use any kind of water softening salt; however we find that extra coarse salt works better than the pellets. You do not have to add water to the brine tank again after this first time during the start‐up. 10. Close the valve after the Nitrate Filter. Connect a garden hose to the hose bib after the Nitrate Filter and open hose bib. Turn on the water to the Nitrate Filter and allow the water to run out the garden hose until the water is clear. 11. See the Clack WS1 Service Manual for instructions on how to program and set Nitrate Filter, and see the next page for nitrate calculations. Your Nitrate Filter is already programmed for the size tank you have, but you do want to set it regenerate for the proper dosage. You can also set the DAY OVER‐RIDE function, so no matter how many gallons you use, it will regenerate every 3 – 7 days etc which would give you a margin of safety should the nitrate levels change in the raw water. However, as long as you have good nitrate test kit and monitor the nitrate levels in the untreated and treated levels, you can verify that your water is low enough in nitrate to be safe to drink. 12. Start a manual backwash by pressing and holding the REGEN button for 5 seconds. 13. Verify that it has sucked up the brine: After Nitrate Filter has been regenerating for 20 minutes, look inside the brine tank and you should see that is has sucked out the brine. At the end of the regeneration (90 minutes) check to make sure that the Nitrate Filter has added water to the bottom of the brine tank to make brine for the next regeneration cycle. Clack WS1 Nitrate Filter Installation Guide How to Calculate How Often to Set System to Regenerate: Example: nitrate as nitrogen is 10.0 ppm or 44.4 ppm as nitrate; Change nitrate to nitrate as nitrate by multiplying times 4.4 Test for sulfate and note sulfate level. Example calculation: Nitrate level (as NO3): 44 ppm x .81 = 36 ppm as CaC04 Sulfate: 34 ppm x 1.04 = 36 ppm as CaC04 Total sum of N03 and Sulfates as CaC04: 72 ppm 72 ppm divided by 17.1 = 4.2 grains (round to 5 grains for conservative calculation) Capacity of resin = 16,000 grains per cu ft Total cubic foot of resin in system: 1.5 cubic foot which = 24,000 grains 24,000 grains divided by 5 grains = 4800 Add in a safety factor to prevent the resin from becoming exhausted each time before regeneration. The safety factor would be the maximum amount of water used in one day. Typically use 80 gallons per person per day. So a four person home would be 320 gallons to use as a buffer or safety factor. So the nitrate filter in this example would be to set it to regenerate approximately every 4480 gallons, or to be safe, set for 4000 gallons. Adjust the hardness setting on the WS1 control until when you are finished programming it reads approximately 4000 gallons. For instance if you set the hardness for 10 and when you are finished, it reads 3500, try setting the hardness for 5 grains. Depending on the size nitrate tank you have, you will need to enter different hardness settings to achieve your desired gallon settings. TEST YOUR WATER REGULARLY TO INSURE THAT THE SETTINGS ARE CORRECT AND YOUR SYSTEM IS FILTERING THE NITRATE TO A SAFE LEVEL. YOUR NITRATE LEVELS MAY VARY SEASONALLY IN YOUR WELL WATER. NITRATE IS ODORLESS AND TASTELESS. WATER HIGH IN NITRATE IS ESPECIALLY DANGEROUS FOR INFANTS AND FETUS. Clack WS1 Nitrate Filter Installation Guide Maintaining Your WS1 Nitrate Filter System WS1 Nitrate Filters require little maintenance other than making sure it does not run out of salt and that it is properly using the salt and that it is drawing in the brine during the brine cycle. If the nitrate filter cannot or does not draw in brine, it will not remove the nitrate. The primary task is to add salt to the brine tank a couple of times a year. You can fill the salt tank to the top if wish and then wait until the brine tank is near empty before adding salt again. Or you can add salt whenever you notice that the salt is low enough to add more bags. If you fail to add to salt the water and your filtered water is again high in nitrate you will notice that there is water in the bottom of the brine tank. This is normal, and you can add salt and press the manual regeneration REGEN button for several seconds to regenerate the Nitrate Filter manually and have nitrate filtered water again. Your Nitrate Filter can use any kind of salt, including extra coarse softening salt, or pellets. It also works with potassium chloride, sometimes sold as K‐Life or Potassium Salt.
