2. Setup and First Use

The Stokk T1 is designed for immediate use with no complex installation required. Simply plug it into a power source. Before first use, it is crucial to perform an initial flushing cycle to ensure optimal performance and remove any manufacturing residues.

2.1 Initial Flushing

1. Fill the raw water tank with tap water.
2. Place the carafe under the dispenser.
3. Initiate a full pot dispense cycle.
4. Discard the water from the carafe.
5. Repeat this process at least 4-6 times to thoroughly flush the system and new filters.

2.2 Mineralization Filter Preparation

If using the included mineralization carafe, ensure the remineralization filter is properly prepared:

• Soak the remineralization filter in water for a sufficient period (refer to the physical manual for exact soaking time, typically several hours) before first use. This helps to activate the minerals and ensure proper water flow.
• Failure to soak may result in slow water flow or issues with mineralization.

3. Operating Instructions

The Stokk T1 features a user-friendly control panel for easy operation. The display provides real-time information and allows for various dispensing options.

3.1 Control Panel Overview

• TDS Display: Shows the Total Dissolved Solids (PPM) of the purified water in real-time.
• Filter Lifespan Indicators: Lights indicate the status of PPC, C, and RO filters. White means normal, red means replacement is needed.
• UV Light Indicator: Flashing indicates working, solid light indicates complete working.
• Purification Indicator: Light on means filtering water, light off means complete filtering.

3.2 Dispensing Water

The Stokk T1 offers multiple volume options for dispensing water:

• Volume Options: Select desired volume (8/12/16/24/30/40 oz) and press the dispense button.
• Faucet Mode: Dispenses water continuously until stopped.
• Half/Full Pot: Automatically fills the carafe to half or full capacity.

4. Filtration Technology

The Stokk T1 employs a sophisticated 6-stage Reverse Osmosis (RO) filtration system, enhanced with UV light, to deliver superior water quality.

4.1 6-Stage Filtration Process

• Stage 1 (Sediment PP): Removes larger particles like rust, sand, and sediment.
• Stage 2 (Pre-activated Carbon): Absorbs chlorine, odors, and organic compounds.
• Stage 3 (0.0001μm RO Membrane): The core of the system, effectively removes 99.99% of TDS, PFAS, heavy metals (lead, arsenic), fluoride, and other dissolved solids.
• Stage 4 (Coconut-Shell Activated Carbon): Further enhances taste and removes residual chlorine.
• Stage 5 (UV Light): Provides an additional layer of purification by eliminating bacteria, viruses, and other microorganisms.
• Stage 6 (Remineralization & Alkaline Filter): Located in the carafe, this stage adds beneficial minerals and boosts the pH of the water for an enhanced taste and health benefits.

• Alkaline Boost: The remineralization filter raises the pH value of the RO water, contributing to antioxidant properties and electrolyte balance.
• Mineral Supplementation: Adds beneficial minerals back into the water for improved taste and health.
• Coconut Shell Activated Carbon: A post-filter further absorbs odors and residual chlorine, enhancing the purity and making the water exceptionally fresher and more crystal-clear.

6. Water Conservation

The Stokk T1 is designed with efficiency in mind, offering significant water savings compared to traditional RO systems.

• High Pure-to-Drain Ratio: With over a 3:1 pure to drain ratio, this system conserves water up to 12 times more effectively than conventional systems.
• Fast Dispense: A rapid 456 GPD (Gallons Per Day) rate allows you to fill a cup in approximately 15 seconds, reducing wait times.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Stokk T1 water filter. The system provides real-time reminders for filter replacement.

7.1 Filter Replacement

The control panel features a real-time filter lifespan detection system that reminds you when to replace filters. Filter replacement is designed to be hassle-free.

7.2 Cleaning

• Regularly clean the external surfaces of the unit with a soft, damp cloth.
• The drip tray should be emptied and cleaned periodically.
• For internal cleaning, follow the system's self-cleaning function as indicated on the control panel.

8. Troubleshooting

This section addresses common issues you might encounter with your Stokk T1.

8.1 Common Issues and Solutions

• E1 Error: If an E1 error appears, unplug the unit, drain the water, and reset it. This often indicates a temporary system anomaly.
• Slow Water Flow from Mineralization Filter: Ensure the mineralization filter was properly soaked before first use. If flow becomes slow over time, re-soaking the filter may resolve the issue.
• Water Leaks: If water leaks from the bottom, immediately unplug the unit and contact customer support.
