Setup Instructions
Follow these steps for initial setup and connection of your water softener:
- Unpack Components: Remove all items from the packaging and verify against the 'Product Components' list.
- Prepare Connections: Ensure all fittings (3/4" GHT) are clean and free of debris. Apply PTFE thread seal tape to all threaded connections to prevent leaks.
- Connect to Water Source: Connect the inlet side of the water softener to your water source (e.g., campground spigot) using the provided hose and adapters. The inlet is typically marked or indicated by the flow direction.
- Connect to RV/Appliance: Connect the outlet side of the water softener to your RV's fresh water inlet or the appliance you wish to supply with softened water.
- Initial Flush: Before connecting to your RV, slowly turn on the water supply and allow water to flow through the softener for several minutes. This flushes out any manufacturing residue and conditions the resin. Direct the flushed water away from your RV.
- Check for Leaks: After connecting and flushing, inspect all connections for leaks. Tighten any leaking connections with the provided wrench, being careful not to overtighten.

Operating Instructions: Regeneration Process
The water softener uses ion exchange resin beads to remove hardness minerals. Over time, these beads become saturated and require regeneration with common table salt to restore their softening capacity. The system is designed for quick regeneration, typically within 30 minutes.

Regeneration Steps:
- Disconnect Water Supply: Turn off the water supply to the softener and disconnect it from the RV.
- Release Pressure: Briefly open a faucet to release any remaining pressure in the system.
- Prepare Brine Solution: Remove the top cap of the softener. Add approximately 2 pounds of common table salt (non-iodized is preferred) to the softener tank. Slowly add water to dissolve the salt, creating a brine solution.
- Initiate Regeneration: Re-secure the top cap. Connect a hose to the inlet side and direct the outlet hose to a drain or suitable disposal area. Slowly turn on the water supply to allow the brine solution to flow through the resin beads and out the drain. This process typically takes 20-30 minutes.
- Rinse Cycle: After the brine solution has passed through, continue flushing with fresh water for another 10-15 minutes to rinse out any excess salt.
- Test Water: Use water hardness test strips (not included) to verify the water is soft before reconnecting to your RV.
Maintenance
Regular maintenance ensures optimal performance and longevity of your NPGLOBAL water softener.
Pre-Filter Replacement:
The integrated 2-stage pre-filter reduces sand, sediment, chlorine, and other impurities. The filter should be replaced periodically, depending on water quality and usage, or when you notice a decrease in water flow or taste/odor issues.

- Turn Off Water: Disconnect the water softener from the water supply.
- Release Pressure: Open a nearby faucet to release system pressure.
- Remove Filter Housing: Use the provided wrench to unscrew the pre-filter holder from the top of the softener unit.
- Replace Filter: Remove the old filter cartridge and discard it. Insert a new replacement filter cartridge into the housing, ensuring it is seated correctly.
- Reassemble: Screw the pre-filter holder back onto the softener unit, hand-tightening first, then using the wrench for a snug fit. Do not overtighten.
- Flush: Slowly turn on the water supply and flush the system for a few minutes to remove any air and carbon fines from the new filter. Check for leaks.
General Care:
- Store the unit in a cool, dry place when not in use.
- Protect the unit from freezing temperatures, as this can damage the resin and housing.
- Periodically inspect hoses and fittings for wear or damage.
Troubleshooting Common Issues
- Low Water Pressure:
Possible Causes: Clogged pre-filter, kinked hose, partially closed valve, or air in the system.
Solutions: Replace pre-filter, check hoses for kinks, ensure all valves are fully open, and flush the system to remove air. - Water Not Softening:
Possible Causes: Resin needs regeneration, insufficient salt during regeneration, or incorrect regeneration procedure.
Solutions: Perform a regeneration cycle with the correct amount of salt, ensuring the brine solution flows through the resin properly. - Leaks at Connections:
Possible Causes: Loose fittings, damaged O-rings, or insufficient PTFE tape.
Solutions: Tighten connections, replace worn or damaged O-rings, and reapply PTFE tape as needed. - Unpleasant Water Taste/Odor:
Possible Causes: Exhausted pre-filter, or the softener resin needs flushing after regeneration.
Solutions: Replace the pre-filter. Ensure a thorough rinse cycle after regeneration to remove all salt residue.
