This document describes the Krausen NEW LINE A-D LCD Water Purifier, an advanced water treatment system designed for indoor use, providing pure water for direct consumption.
Function Description
The Krausen NEW LINE A-D LCD Water Purifier utilizes advanced international Reverse Osmosis (RO) technology to produce clean, healthy drinking water. The purification process involves a five-stage filtration system:
- First Stage (10-inch 5-micron PP filter): This filter effectively removes rust, sand, and other larger particles and solid impurities from the water.
- Second Stage (10-inch carbon block CTO filter): This stage adsorbs chlorine, humus, disinfection by-products, odors, colors, and other materials.
- Third Stage (10-inch 1-micron PP filter): This filter further removes small particles, suspended solids, and colloids.
- Fourth Stage (Two RO membranes filters): The RO membranes are crucial for removing bacteria, viruses, heavy metals, pesticide residues, and other harmful substances. For systems with multiple membranes, the first membrane typically has the largest capacity (e.g., 200 gallons), followed by smaller capacities (e.g., 180 gallons).
- Fifth Stage (Coconut activated post carbon filter): This final stage regulates water taste and keeps the water fresh.
The system is designed without a storage tank, allowing users to obtain pure water directly as it is produced, which prevents contamination issues like odors and bacteria associated with long-term water storage.
Accessory Functions:
- High Pressure Pump: Boosts pressure to ensure stable operation of the RO membrane.
- Flow Restrictor: Controls the flow of waste water.
- Low Voltage Switch: Prevents pump idling by automatically shutting off power if inlet water pressure drops below 0.03 MPa or if the water supply stops.
- High-Voltage Switch: Prevents the pump from continuously running. It automatically cuts off power when the goose neck faucet is closed and the pressure reaches the set level.
- Inlet Water Solenoid Valve: Connects or cuts off incoming water, operating within a pressure range of less than ≤0.6MPa.
- Non Return Valve (One-way valve): Controls water flow direction.
- Flush Solenoid Valve (Optional for LCD models): Helps clean the membrane surface, prevents bacterial growth, and extends membrane life. It operates automatically.
- LED / LCD Controller (Optional computer controller): Operates all functions, including automatic membrane cleaning.
- Leakage Sensor: Provides leakage protection.
LCD Controller Features (KRAUSEN NEW LINE LCD):
The LCD controller provides real-time system status indicators:
- FLUSH: Indicates membrane flushing is in progress (automatic cleaning every 7-8 hours or after long work periods, lasting 0.5-1.5 minutes).
- FULL: Indicates the drinking goose neck faucet is closed.
- PURIFY: Indicates the machine is purifying water.
- SOURCE: Indicates sufficient inlet water pressure.
- REPAIR: Indicates a system malfunction requiring repair.
- LEAK: Indicates a water leak detected by the sensor.
- Filter service life: Displays the remaining life of the filters.
- INLET water TDS: Shows the original water TDS value (range 0-999).
- PURE water TDS: Shows the purified water TDS value (range 0-199).
- "Strong washing" button: Manual flush initiation for membrane cleaning.
Control Functionality:
- Flush Function: Initiates membrane flushing for 90 seconds upon power-on, or 90 seconds when activated in purify state, or 30 seconds when exiting source state, or 30 seconds after 2 hours of cumulative purification.
- Source Function: Enters source state if the low-pressure switch is open for more than 60 seconds. Flushes membrane for 30 seconds if the low-pressure switch is closed.
- Full Function: Flushes membrane for 5 seconds if the high-pressure switch is open and the machine has purified water for more than 10 minutes. If less than 10 minutes, the flush solenoid powers on for 10 seconds.
- Purify Function: Enters purify state if the high-pressure switch is closed.
- Repair Function: Enters repair state if the machine purifies water for more than 6 continuous hours and the tank is not full.
- Leakage Function: Enters leakage state if the leakage sensor detects water leakage for more than 5 seconds.
Important Technical Specifications
The Krausen NEW LINE A-D LCD water purifiers come in various models (A, A++, B, C, D) with different electrical and performance parameters.
General Specifications:
- Voltage: AC 220V, 50Hz.
- Power Rating: Ranges from 43W (Line A) to 115W (Line D).
- Inlet Water Pressure: Recommended 0.1MPa to 0.35MPa.
- Working Pump Pressure (on membrane): Optimal 5.0–7.0 bar.
- Inlet Temperature: 5-38 °C.
- Maximum Inlet Water TDS Value: ≤1000 ppm.
- Drinking Water Production Volume: Ranges from 1000 ml/min (Line A) to 4100 ml/min (Line D).
- Waste Water Production Volume: Ranges from 600 ml/min (Line A) to 1100 ml/min (Line C).
- Electric Shock Protection Type: Type II for all models.
- Hardness Level (max mg-ekv/lit): 8 for all models.
- MAX Pure Water Flow per day (Lit): Ranges from 40 (Line A) to 120-140 (Line D).
Note: Product improvements may lead to parameter changes, but the product name plate may remain the same. Drinking water/waste water volumes can vary based on membrane quantity, type, water/room temperature, pump pressure, and membrane capacity. High hardness levels can reduce membrane life; prefiltration filters (Krausen water softeners or Aqua Mix Ion systems) and antiscalant liquid are recommended for high TDS.
Usage Features
- Direct Consumption: Produces pure water suitable for direct consumption.
- Tankless Design: Eliminates the need for a storage tank, preventing contamination and ensuring fresh water on demand.
- High Production Capacity: Offers significantly higher production capacity compared to standard 50G systems (up to 8 times).
- Easy Installation/Uninstallation: Features quick-fitting connectors for input and output water sides.
- Initial Operation: During the first hour of operation, the produced water should be discarded due to protective solutions in membranes and activated carbon powder from the post-carbon filter.
- TDS Stabilization: The pure water TDS value may be high initially and will gradually decrease to a stable level after some operation.
- Normal Operation: Ensure the inlet water ball valve is open and the pure water faucet is turned on. When not in use, turn off the water faucet; the high-pressure switch will automatically cut off the water supply.
- Safety Precautions: Always ensure the water purifier's integrity for safe use. Avoid using the purifier if the sewer is blocked, under high water pressure (above 0.35MPa), or in temperatures below 5°C or above 38°C. Do not expose to direct sunlight or corrosive materials. Do not place heavy objects on top or near fire sources.
Maintenance Features
Filter Replacement Time (Estimates based on average tap water use and a three-person family using 10L/day):
- First (10-inch 5-micron PP filter): 2-6 Months
- Second (10-inch carbon block CTO filter): 3-6 Months
- Third (10-inch 1-micron PP filter): 3-6 Months
- Fourth (RO Membranes): 2-3 years
- Fifth (Coconut activated post carbon filter): 1 Year
Note: Actual filter lifespan can vary significantly based on water quality, utilization rate, and other factors. Replacement should be based on actual usage and performed by after-sales staff.
Filter Replacement Method:
- PP Filters (1st and 3rd stage): Close the inlet water ball valve, unscrew the filter cartridges with a wrench, remove old filters, insert new ones (5-micron in 1st stage, 1-micron in 3rd stage), and tighten.
- Carbon Block CTO Filter (2nd stage): Close the inlet water ball valve, unscrew the filter cartridge, remove the old filter, insert the new filter (rubber pad does not need to be removed), and tighten.
- RO Membranes: Refer to "RO Membrane Installation" instructions (Page 8). Ensure correct direction and proper seating of the O-ring. Do not force membranes into the shell.
Notes on Maintenance:
- RO Membrane Production Volume: Depends on the system model and configuration.
