Product Name: CSpring Mk3® Automatic CPAP Water Chamber Refill System

Product Type: Automatic CPAP/BiPAP humidifier water chamber replenishing system

Main Function: Automatically monitors and refills compatible CPAP/BiPAP water chambers when the water level gets low.

How It Works: The Mk3 uses external water-level sensors placed on the outside of the CPAP water chamber. When the water drops below the low-level sensor, the system activates the internal pump and sends water from the CSpring reservoir into the CPAP chamber.

Software Logic: The Mk3 is controlled by updated software logic designed to manage refill timing and reduce overfilling. During normal refill operation, the pump runs for up to 9 seconds per refill cycle. The system uses the sensor signal to determine when to refill and when to stop.

Sensor System: Includes external low-water and high-water sensor controls. The sensors do not touch the water and are installed on the outside of the compatible CPAP water chamber using replaceable sensor clips.

Sensor Clips: Replaceable adhesive clips hold the sensors in the correct position on the water chamber. Clips are consumable parts and should be replaced as needed to maintain proper sensor performance.

Water Pump: Internal water pump rated up to 350 L/h.

Reservoir: Large-capacity external water tank designed to reduce the need for nightly manual refilling.

Tank Material: Durable plastic reservoir made with a silver-infused additive to help keep the tank cleaner during normal use.

Water Line: Includes standard water tubing to connect the Mk3 reservoir to the compatible CPAP water chamber lid or adapter.

Power Adapter: Includes multi-voltage power adapter compatible with 110–120V and 220–240V power input.

Setup: Connects to the compatible CSpring chamber, complete chamber, or top-lid adapter depending on the selected model.

Cleaning & Maintenance: Reservoir and tubing should be cleaned regularly. Sensor clips should be replaced as needed, especially if refill performance changes.

Included Parts: CSpring Mk3® reservoir unit, water tubing, sensor cable, sensor clips, power adapter, and the selected compatible water chamber or top-lid adapter option depending on the model ordered.

Best For: CPAP/BiPAP users who use humidification, high humidity settings, experience dry chamber issues, or want to reduce nightly water refilling.

Important Note: Proper clip and sensor placement is required for correct operation. The Mk3 should always be installed according to the included instructions.

The CSpring Mk3® Automatic CPAP Water Chamber Replenishing System is designed to help maintain water levels in compatible CPAP humidifier chambers. Proper operation depends on correct installation, routine maintenance, periodic inspection, and use in accordance with all provided instructions.

Users are responsible for ensuring that sensors, clips, tubing, water chambers, and related components are installed and maintained correctly. Improper installation, incorrect sensor placement, failure to replace consumable components, damaged equipment, incompatible equipment, or failure to follow instructions may result in water leakage, overfilling, equipment damage, or other unintended conditions.

Before regular use, users should verify proper operation and periodically inspect the system to ensure all components remain securely installed and functioning as intended.

By purchasing or using this product, you acknowledge that the use of water near electrical and medical equipment carries inherent risks and that proper setup, maintenance, and monitoring are required.

To the fullest extent permitted by applicable law, CSpring LLC shall not be liable for indirect, incidental, consequential, special, or punitive damages arising from misuse of the product, improper installation, failure to follow instructions, unauthorized modifications, use with incompatible equipment, or failure to properly maintain the system.

By using this product, you agree to assume responsibility for its proper installation, operation, maintenance, and inspection, and you agree to hold harmless and indemnify CSpring LLC from claims, damages, losses, costs, or expenses arising from misuse, negligence, improper installation, unauthorized modification, or use contrary to provided instructions.

Tank Material: Durable plastic reservoir made with a silver-infused additive. Silver additives are commonly used in plastics to help inhibit the growth of certain bacteria on the material surface. This feature is intended to help support cleaner tank material during normal use, but it does not replace regular cleaning and is not intended to sterilize, disinfect, or guarantee antimicrobial performance of the complete Mk3 system.

Silver ion anti-microbial technology harnesses the natural antibacterial properties of silver to combat the growth of bacteria and other harmful microorganisms. This technology works by releasing silver ions, which are effective in destroying the cell walls of bacteria upon contact, thereby inhibiting their ability to multiply and spread.

Key Features of Silver Ion Anti-microbial Technology:

• Broad-Spectrum Antimicrobial: Silver ions provide a wide-ranging action against bacteria, viruses, and fungi, reducing the risk of infections and contamination.
• Long-Lasting Protection: The release of silver ions continues over an extended period, offering durable antimicrobial effects that help maintain hygiene and cleanliness.
• Non-Toxic and Safe: Unlike some chemical disinfectants, silver ion technology is generally considered safe for human contact and the environment when used appropriately.
• Versatility: This technology can be integrated into various materials including plastics, textiles, coatings, and medical devices, enhancing their antimicrobial properties without altering their physical characteristics.
• Prevent Biofilm Formation: By disrupting the growth and proliferation of bacteria, silver ions help prevent the formation of biofilms, which are protective layers that bacteria build to shield themselves from external threats.

Applications of Silver Ion Anti-microbial Technology:

• Healthcare: Used in medical devices, hospital equipment, and textiles to reduce the spread of healthcare-associated infections (HAIs).
• Consumer Products: Integrated into products like kitchen utensils, refrigerators, and air conditioners to ensure surfaces remain hygienic.
• Textiles and Apparel: Applied to clothing, especially sportswear and socks, to control odor and prevent bacterial growth.
• Water Treatment: Used in water filtration systems to eliminate bacteria and other pathogens, ensuring safe drinking water.

Silver ion anti-microbial technology provides an effective, long-lasting, and versatile solution for enhancing the antimicrobial properties of products and surfaces, contributing significantly to public health and hygiene.

Does the Mk3 modify the function of my CPAP machine?
No. The Mk3 works alongside your CPAP humidifier chamber and does not modify the CPAP device.

How long does the water tank last?
The external reservoir can supply water for multiple nights depending on humidity settings and usage.

Is installation difficult?
No. Installation typically takes only a few minutes.
