Choosing an Install Location
1. Choose a location that allows for an acceptable drain route that can handle the water flow and has an air gap. Also make sure the location is easily accessible for salt loading and servicing.
2. Use the graphic below to determine the appropriate position based on a city or well water source:
Plumbing the Unit
1. Unpack and position the unit so the water will come IN and OUT through the labeled ports on the valve head. Turn off the main water supply and shut off the electric or fuel supplying the water heater. Open high and low faucets to drain the house pipes.
2. Remove the top cover and wire connections from PWA. Set to side to keep from getting damaged.
3. Load media into the unit if applicable. Visit our Media Loading article for directions. Remember some units recommend Soaking the Media before pressurizing - this can reduce the risk of media loss.
4. Install a single bypass or 3-valve bypass system. A single bypass can be flipped upside down if the home plumbing comes from below.
5. Lubricate o-rings and connect tank filter to bypass assembly. Attach black retainer clips and check they are fully engaged by giving the bypass assembly a small tug away from the valve.
6. If home has copper plumbing or other metal, be sure to include a grounding wire:
7. Install the drain hose (not included). The recommended size is 5/8" or 3/4" to handle the drain flow. At the drain location, be sure to add an air gap (1 1/2") and secure the drain hose to prevent whipping during regeneration:
Pressurize and Purge
*To avoid water or air pressure damage, follow these steps in order*
1. Bypass the unit and open two or more cold-water faucets downstream of the unit.
2. Slowly open the main water supply and run water until you receive a steady flow from both faucets.
3. Check for leaks at the valve and bypass assemblies.
4. With the faucets still open, SLOWLY open the bypass, pausing several times to allow the filter to pressurize slowly.
5. After about three minutes, open a hot water faucet and leave open until the stream runs smooth (no air).
6. Check again for leaks. Turn on the gas or electric heater (if applicable) and light the pilot if needed.
Programming
Visit our Programming instructions for assistance setting up the electronics.
Cycle Check
A cycle check reduces air and discoloration in the water, and allows us to check that the drain can handle flow.
1. Remove the top cover and observe the cam and switch operation during valve rotation.
2. Use the 'Recharge Now' button to imitate a regeneration (40 minute duration).
3. After the regen, open a cold faucet downstream of the filter and allow 50 gallons of water to pass through (20 minutes).
Installation Wrap-up
1. Clean up the installation area.
2. Apply the company sticker and test the water.
3. Show the customer how to use the bypass assembly. Mention there may be air in the lines initially, but it will work itself out.

1. Choose a location that allows for an acceptable drain route, into a drain that can handle the water flow and has an air gap. Also make sure the location is easily accessible for salt loading and servicing.
2. Use the graphic below to determine the appropriate position based on the water direction through the home plumbing:

Pressurize and Purge
*To avoid water or air pressure damage, follow these steps in order*
1. Bypass the unit and open one cold and one hot water faucet downstream of the unit.
2. Slowly open the main water supply and run water until you receive a steady flow. Close both faucets.
3. Check your plumbing work for leaks, and turn on gas or electric water heater, lighting pilot if necessary.
