Setup and Installation

This section outlines the steps for replacing the filters in your Nimbus WaterMaker 5 Reverse Osmosis system. It is recommended to replace filters annually for optimal performance.

Required Tools:

• Bucket or towel for minor water spills.
• Gloves (optional).

Filter Replacement Procedure:

1. Turn off Water Supply: Locate the cold water supply line to your RO system and turn off the shut-off valve.
2. Depressurize System: Open the RO faucet to relieve pressure from the system. Allow water to drain until it stops flowing.
3. Remove Old Filters:
   • Identify the 4-Stage Desalinator filter (Part #104592) and the Stage 5 GAC Post Filter (Part #101803).
   • For the 4-Stage Desalinator, gently twist and pull to disconnect it from its fittings. Some models may require pressing a collet to release the tubing.

   • For the Stage 5 GAC Post Filter, note the flow direction indicated on the filter. Disconnect the tubing from both ends by pressing the collets and pulling the tubing out.

4. Install New Filters:
   • Insert the new 4-Stage Desalinator filter into the system, ensuring a secure fit.
   • Connect the tubing to the new Stage 5 GAC Post Filter, observing the flow direction arrows on the filter. Push the tubing firmly into the quick-connect fittings until seated.

5. Restore Water Supply: Slowly turn on the cold water supply valve to the RO system.
6. Flush System: Open the RO faucet and allow the system to flush for at least 10-15 minutes. This flushes out any carbon fines and air from the new filters. The water may appear cloudy initially; this is normal.
7. Check for Leaks: Carefully inspect all connections for any signs of leaks. Tighten connections if necessary.
8. Close Faucet: Once the water runs clear and all air is purged, close the RO faucet. The system will begin to fill the storage tank.

Operating Instructions

The Nimbus WaterMaker 5 system operates automatically once installed. When the RO faucet is opened, purified water flows from the storage tank. When the faucet is closed, the system will automatically produce more purified water to refill the tank.

• Initial Fill: After installation, allow 2-3 hours for the storage tank to completely fill. The first tank of water should be drained completely to ensure proper flushing of the new filters.
• Water Taste: The system is designed to provide clean, great-tasting water. If you notice any unusual taste or odor, refer to the Troubleshooting section.
• Flow Rate: The system delivers 30% higher flow from the faucet compared to older models. Flow rate may decrease as filters approach the end of their lifespan.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your Nimbus WaterMaker 5 system.

• Filter Replacement: The replacement filter kit (Part #104208) should be replaced annually. This includes the 4-Stage Desalinator (Part #104592) and the Stage 5 GAC Post Filter (Part #101803). Annual replacement ensures consistent water quality and system efficiency.
• System Cleaning: Periodically wipe down the exterior of the system and tubing with a clean, damp cloth. Do not use harsh chemicals.
• Leak Checks: Routinely check all connections for any signs of leaks, especially after filter replacement.
