- Connect to RV/Appliance: Connect the outlet side of the softener (marked "OUT" or typically the side with the female garden hose fitting) to your RV's main water inlet, boat's water system, or pressure washer.

Operation
Once installed, the water softener operates automatically as water flows through it. The resin inside the tank performs ion exchange, removing hardness minerals.
Applications:
- RV and Trailer Use: Provides soft water for all onboard needs, including showering, washing dishes, and drinking, preventing scale buildup in pipes and appliances.
- Boats and Marinas: Ideal for marine applications to prevent hard water spots and protect plumbing systems.
- Mobile Car Washing/Pressure Washing: Eliminates water spots and enhances soap lathering for a streak-free finish on vehicles.
- Spas and Hot Tubs: Helps maintain water quality and reduces mineral deposits in spa equipment.

Maintenance and Regeneration
The water softener requires periodic regeneration to replenish its resin beads and restore its softening capacity. The frequency depends on water hardness and usage, typically every 40-60 days or after 2,000 gallons of use.
Standard Regeneration Process:
- Disconnect Hoses: Disconnect the water softener from both the water source and your RV/appliance.
- Drain Unit: Lay the unit on its side to drain any remaining water.
- Add Salt: Remove the top cap and add approximately 4 lbs of common table salt (non-iodized is preferred) into the tank.
- Soak: Allow the salt to sit for 40-60 minutes, shaking the unit gently every 10 minutes to help dissolve the salt.
- Rinse: Reconnect the hoses and run water at a slow speed for 10-15 minutes to flush out the salt solution. Increase water speed for 1-2 minutes until the unit is fully flushed and the water runs clear.
For faster regeneration, consider the optional Regeneration Kit (sold separately), which can complete the process in less than 30 minutes using 2 pounds of salt.

Troubleshooting
If you experience issues with your PRO+AQUA Portable Water Softener, consider the following common troubleshooting steps:
- Water Not Softening:
- Check if the unit needs regeneration. The resin's capacity may be exhausted.
- Ensure proper connection and water flow direction (IN to OUT).
- Verify that sufficient salt was used during the last regeneration and that it fully dissolved.
- Low Water Pressure:
- Check for kinks in hoses or blockages in fittings.
- Ensure the water source pressure is adequate.
- If using a pre-filter, check if it is clogged and needs cleaning or replacement.
- Leaks at Connections:
- Tighten all hose connections.
- Check for damaged O-rings or washers and replace if necessary.
- Apply plumber's tape (Teflon tape) to threaded connections for a better seal.
- Unusual Taste/Odor After Regeneration:
- Ensure the unit was thoroughly flushed after adding salt. Residual salt can affect taste. Continue flushing until water is clear and taste is normal.
