Precautions:
- For all installations: Anticipate the need for additional parts and pieces including but not limited to pex tubing, clamps, and mounting screws to install the unit properly.
- DO NOT install this conditioner where the line pressure may exceed 100 psi. The operating pressure range is between 20psi – 100psi. In areas with high pressure, a pressure relief valve and a water hammer arrestor may be necessary.
- Install on cold water lines only (40° – 90°F).
- Installation must comply with existing state and local plumbing codes.
- Some local codes may require a licensed plumber or certified installer.
- It is recommended to install the system indoors and out of direct sunlight. Prolonged exposure to light can weaken plastic components. If installed outdoors or in a sunny area, protect from direct sunlight and freezing temperatures.
- Unit must be installed where the main water line enters your home, before connecting to the water heater. DO NOT install after a water heater or on the hot water line.
- DO NOT install the tank on its side. It must be installed upright.
- Allow adequate clearance: minimum 46" height for Standard tank, 57" for Tall tank, and 44" floor space.
- Conditioner tank must be flushed before running water from the system into the house.
- Use only NSF certified plumber's tape on threaded fittings. DO NOT use pipe dope or PVC primer/glue.
- Properly tighten all fittings to ensure a leak-free assembly.
- If installing on metallic plumbing, two grounding clamps and #4 copper wire are essential for safety.
- It is strongly recommended to install a check valve at the end of your system configuration and before the water heater to protect against back flow.
① Select Location
Lay out system in appropriate configuration. Improper sequencing of equipment will affect performance and could possibly damage your system.
- Pick an appropriate installation location where the main water line enters your home, and before it connects to the water heater. Install after any outdoor hose bibs or irrigation lines to avoid using conditioned water where not needed. DO NOT install after the water heater or on the hot water line.
- Choose the location for a shut-off valve to isolate your system. If installing a check valve, install it after your system but before the water heater.
② Prepare Salt-Free Water Conditioner
- Ensure the Salt-Free Water Conditioner tank sits level. Reference the troubleshooting section if it appears off-center or unlevel.
- Pre-assemble all parts and dry-fit the entire system to ensure proper spacing and confirm necessary components. Reference the system configuration image on page 3.
- Connect all smooth fitting connections using NSF certified primer and glue. Apply primer and glue, then press and hold the connection tight for 10-15 seconds.
- Carefully remove shipping caps from inlet and outlet ports without damaging valve threads.
- Wrap threaded nipple ends 3 times with NSF certified plumber's tape. Insert nipples and attached unions to the filtration tank's threaded inlet and outlet. Hand tighten, then tighten with a pipe wrench (2-2.5 rotations) to seal connections.
DO NOT OVER-TIGHTEN. If space does not allow for a pipe wrench, clamp to the glued union to make final rotations.
③ Copper Pipes Only (proceed to Step 4 for all other pipes)
When installing on metallic plumbing, securely install two (2) grounding clamps and a #4 copper wire (not included) across the location where the system will be installed. Tightly clamp at both ends, as shown in the illustration.
Diagram illustrating grounding clamp installation for metallic plumbing. Two grounding clamps are shown attached to copper pipes, connected by a copper wire.
Prior to installation on metallic plumbing, securely install two grounding clamps and a #4 copper wire per installation instructions. Failure to follow these instructions can result in death or electric shock.
④ Install Shut-off Valve and Ensure Spacing
You may need additional components to connect your system to the main water line. Ensure you have all components needed before proceeding.
- Turn off the main water source. Drain water from lines to relieve pressure by turning on a faucet at the lowest elevation inside your home.
Installation could take 1–4 hours to complete. You will be without water throughout the home during this time.
- Using a pipe cutter, cut into the main water supply line and catch any remaining water in a 5-gallon bucket. The system includes a 1" PVC shut-off valve with threaded or smooth connections, and reducer bushings for a 3/4" main water line.
- Loosely fit the shut-off valve to calculate proper spacing of components.
- Measure distance for Pre- and Post-Filter, and optional add-ons and mark pipe accordingly.
⑤ Cut Pipes
DO NOT cut more pipe than necessary. You can cut more pipe later if needed.
Ensure proper spacing to fit Pre and Post-Filters, and any optional add-ons.
Diagram showing the water conditioner system layout with incoming and outgoing water supply lines. It illustrates the placement of filters and tanks.
Cut pipe along the marked sections from step 4 and clean ends of pipe. Ensure there are no burrs, sharp edges, or deep scratches.
Diagram showing correct and incorrect pipe cuts. The 'CORRECT' example shows a clean, straight cut, while the 'INCORRECT' example shows a jagged, uneven cut.
Cut tubing as straight as possible with a utility knife, or an appropriate pipe cutter for copper, PVC, or PEX tubing.
⑥ Assemble Drain Valve
All threads are NPT tapered pipe threads.
- Using PVC primer and glue, assemble the piping as shown in Figure 1, applying primer and glue. Ensure enough glue cure time before running water through the system.
- Wrap the 1/2" male drain end 2-3 times with plumber's tape (Figure 2).
- Hand tighten the drain valve into the 1/2" female threaded tee. Then, tighten 1-2 more turns with a wrench (Figure 3).
DO NOT OVER TIGHTEN. There should be a gap between the drain valve threads and tee. Tightening the 1/2" brass drain valve more than 2 turns with a wrench can cause the tee to crack.
Diagrams illustrating the assembly of the drain valve. Figure 1 shows PVC piping with primer and glue. Figure 2 shows plumber's tape applied to a male drain end. Figure 3 shows a correctly tightened drain valve into a tee, with a visual indicator of a gap between threads, and a warning against over-tightening.
⑦ Configure System
- Fit Salt-Free Water Conditioner tank and additional optional add-ons into the system.
- Attach the shut-off valve to your incoming water line.
- Connect the threaded nipple from the shut-off valve outlet to the 20" Pre-Filter housing inlet with NSF certified plumber's tape.
- Attach the filter wall bracket to the Pre-Filter housing with included screws. Screw the support bracket to the wall.
Additional materials may be needed to ensure Pre-Filter and Post-Filter brackets are supported and properly secured to the wall.
- Ensure all parts are flowing through the "IN" port in the correct direction of water flow.
- Connect the threaded nipple from the Pre-Filter outlet to the union attached to the Salt-Free Water Conditioner tank inlet.
- Using the drain valve assembly from step 6, connect it to the union attached to the Rhino® tank outlet as well as the Post-Filter inlet with included nipples.
- Attach the Post-Filter bracket and housing to the wall, similar to the Pre-Filter, and ensure all connections are tight.
- If you have additional attachments, reference those manuals before final installation.
- Once installation is complete, allow proper time for the glue to dry according to manufacturer instructions.
⑧ Flush Your System
It's imperative that this system is flushed properly prior to system water entering your house.
- Connect a garden hose to the integrated drain valve and ensure the drain valve is in the open position.
- Ensure the garden hose outlet is directed towards a floor drain or outdoor area.
- Slowly turn the water on from the initial shut-off valve and inspect for leaks. If any leaks are detected, refer to the troubleshooting section. If no leaks are detected, proceed with the flushing process.
- Slowly turn the water on and allow discolored water to flow from the drain valve into a suitable drainage area.
Diagram showing the assembled water conditioner system connected to a garden hose at the drain valve, with water flowing out towards a floor drain or outdoor area. This illustrates the flushing process.
After the initial 15-minute flushing, begin a period of "surge flushing" by turning the water supply on for 30 seconds and then off for 30 seconds, repeating the cycle for 15 minutes or until the initial surge of water is completely clear and free from discoloration and cloudiness.
Final installation is complete. You may now close off the drain valve.
Do not drink flushed water.
Troubleshooting Guide
| Issue | Resolution |
|---|---|
| Component is missing or arrived damaged. | Call customer service @ 1 (866) 662-6885 option 1, then option 2, then option 1. Have order number, model number, and pictures of damaged packaging and/or unit ready. |
| Tank leans to one side or is not level | Lift the tank straight up and tap down on the ground until the tank stands vertically. The bottom of the tank is round and the boot allows the tank to stand upright. |
| Water leak at seam of tank divider | Valve o-ring may not be placed properly or the top or bottom tank may have loosened during shipping. Use a rubber strap wrench to tighten tanks. If leak continues, contact customer service with a pre-recorded video of the leak. |
| Water leak from Aquasana fittings or drain valve |
|
| Water leak from pre/post filter housing |
|
| Reduced water pressure after installation | It is recommended that the sediment pre-filter be replaced every 2 months depending on sediment levels. If pressure is slowing, check and replace the sediment filter if necessary. |
| Water appears gray or cloudy | Let air flush from water lines. Cloudy water will dissipate over time (can take a week to a month) and is completely harmless. |
| Taste/odor of water did not improve | Ensure bypass loop is turned off and system shut-off valves are open. |
Maintenance
Cleaning
- The exterior of your filtration system can be cleaned with warm, soapy water. Do not use any abrasive solution.
- Rinse well with clean water.
Never use chemical cleaning products on the system's exterior surface as they may damage the housing.
Filter Replacements
Pre/Post-Filter Replacements
Whole House 20" Pre-Filter Cartridge Replacement: Replace every 2 months. Replace sooner if there is a noticeable decrease in water flow.
Whole House 10" Post-Filter Cartridge Replacement: Replace every 6 months. Replace sooner if there is a noticeable decrease in water flow.
Pre/Post-Housing Replacement: Replace every 5 years. To replace, call Customer Support.
How to change the Pre/Post-Filters:
- Shut the filter system off at the shut-off valve (A). Place a 5 gallon bucket under the system drain valve and open valve. This will relieve water pressure and drain excess water.
You must relieve the pressure in your system before attempting to change any Pre-Filter or Post-Filter.
- Remove the blue filter housing by turning the lower ring to the right, using the wrench supplied with your filter system. Remove the used filter.
- If necessary, clean the inside of the blue filter housing with mild soapy water, rinse and dry.
- Place new filter in the center of the blue filter housing.
- Clean the housing o-ring and relubricate it with silicone grease. Set the o-ring into the proper groove and reattach the housing by screwing it back onto the top piece.
DO NOT USE PETROLEUM JELLY as lubrication on the system or o-rings.
- After reassembly, turn the system back on at the shut-off valve.
- Run water, with the bucket still under the Pre-Filter. Check for leaks.
Salt-Free Water Conditioner Tank Replacement
① Shut Off Water Supply
- Turn off the main water source prior to tank replacement or turn off the shut-off valve.
- Place a 5 gallon bucket under the system drain valve and open valve. This will relieve water pressure and drain excess water.
You must relieve the pressure in your system before attempting to change the Salt-Free Water Conditioner tank.
If you have copper pipes - leave your grounding clamps installed. Do not disconnect at any time while changing the tank. Failure to follow this instruction can result in death or electric shock.
② Remove Tank from System
- Loosen the unions on both sides of the Salt-Free Water Conditioner tank. Slide the entire tank (pipe nipples and halves of unions included) away from the system.
- Unscrew the pipe nipples from the tank.
- Dispose of the old Salt-Free Water Conditioner tank properly.
③ Reconnect Fittings
- Clean the threads on the pipe nipples and re-apply new NSF certified plumber's tape.
