1. Introduction
The Frizzlife PX500-A is a tankless reverse osmosis (RO) water filtration system designed to provide clean, great-tasting water directly from your tap. This system utilizes advanced filtration technology, including an alkaline remineralization stage, to remove a wide range of contaminants while adding beneficial minerals back into the water. Its compact, tankless design saves significant under-sink space and reduces the risk of secondary contamination.

2. Key Features
- Superior Filtration Performance: Utilizes a 0.0001 micron RO membrane (ASR313-500g) to eliminate over 1000 types of contaminants (99.99%), including fluoride, chlorine, chloramine, TDS, lime, lead, and other heavy metals.
- Tankless Design: High capacity of 500 gallons per day (GPD) eliminates the need for a traditional storage tank, saving up to 70% under-counter space and preventing secondary contamination.
- Easy Installation: Pre-loaded filters and an integrated design allow for self-installation with minimal effort. All necessary components are included.
- Filter Life Monitor & Quick Change: Integrated monitor indicates when filter replacement is needed. Filters can be replaced in approximately 2 seconds with a simple twist mechanism.
- Remineralization & Alkalization: The post-alkaline filter (ASR313-A) adds essential minerals and increases water pH to over 7.5 for improved taste and health benefits.
- High Efficiency: Achieves a pure to drain ratio of 1.5:1, significantly reducing water waste compared to conventional RO systems.

4. Setup & Installation
The Frizzlife PX500-A system is designed for easy DIY installation. Follow these steps carefully. It is recommended to watch the official installation video for visual guidance.
4.1 Pre-Installation Checklist
- Ensure you have adequate space under your sink for the unit (Dimensions: 35.56 x 12.7 x 45.72 cm).
- Confirm all package contents are present.
- Gather necessary tools: adjustable wrench, drill (if drilling a new faucet hole), screwdriver, utility knife.
- Turn off the cold water supply to your sink.
4.2 Installation Steps
- Install the RO Faucet: If you don't have an existing hole, drill a 1-inch hole in your countertop or sink. Secure the new faucet using the provided hardware.
- Connect the Feed Water Adapter: Locate your cold water supply line under the sink. Install the feed water adapter (T-valve) to divert water to the RO system. Ensure a tight seal using plumber's tape.
- Install the Drain Saddle: Choose a suitable location on the drain pipe (above the P-trap). Drill a 1/4-inch hole and secure the drain saddle.
- Connect Tubing:
- Connect the red tubing from the feed water adapter to the "IN" port on the PX500-A unit.
- Connect the white tubing (1/4") from the "RO" port on the unit to the RO faucet.
- Connect the black tubing from the "DRAIN" port on the unit to the drain saddle.
- Place the PX500-A Unit: Position the unit upright under the sink.
- Connect Power: Plug the power adapter into a standard electrical outlet.
- Flush the System: Turn on the cold water supply. Open the RO faucet and let the water run for 15-30 minutes to flush the system and remove any carbon fines. Close the faucet.

5. Operation
5.1 Dispensing Water
To dispense purified water, simply open the dedicated RO faucet. The system will automatically activate and begin producing water. The flow rate is approximately 0.4 GPM (gallons per minute) at 60 psi.
5.2 Indicator Lights
The control panel on the front of the unit features indicator lights to provide system status and filter life information:
- Blue Light: Indicates normal operation and good filter status.
- Red Light: Indicates that a filter needs replacement. The system may also emit an audible beep.

6. Maintenance
6.1 Filter Replacement Schedule
Regular filter replacement is crucial for maintaining optimal system performance and water quality. The system's filter life monitor will alert you when a filter change is necessary.
| Filter Stage | Filter Model | Replacement Frequency |
|---|---|---|
| 1st Stage (PPC) | ASR311 | Every 6 months |
| 2nd Stage (RO Membrane) | ASR313-500g | Every 2 years |
| 3rd Stage (Post-Alkaline) | ASR313-A | Every 1 year |
6.2 How to Replace Filters
Filter replacement is a quick and simple process:
- Turn off the water supply to the RO system at the feed water adapter.
- Unplug the power adapter from the electrical outlet.
- Locate the filter cartridge to be replaced.
- Twist the old filter cartridge counter-clockwise to unlock and remove it.
- Insert the new filter cartridge, aligning the arrows, and twist clockwise to lock it into place.
- Turn on the water supply and plug in the power adapter.
- Flush the new filter by running water from the RO faucet for a few minutes as per the filter's specific instructions.
