Water Presence Sensor

Product Model: AQUA

Thank you for choosing the "AQUA" Water Presence Sensor! This product is designed to help you promptly detect potential water damage risks, protecting your home, office, or valuable equipment from damage caused by leaks or overflows. Please read this manual carefully before use.

I. Product Overview

The "AQUA" Water Presence Sensor is an intelligent and sensitive water monitoring device. When it detects the presence of liquid water in its sensing area, the device sends an alert notification via wireless signal to a connected relay hub or mobile APP, allowing you to be informed of the situation immediately.

II. Product Features

• Highly sensitive detection: Precise sensors quickly detect minimal contact with liquid water.
• Instant multi-alarm:
  • a. Local visual alarm: Built-in prominent LED indicator flashes.
  • b. Wireless remote alarm: Supports protocols like BLE, Wi-Fi, and other proprietary RF to push alert information to the dedicated APP.
• Wireless design, flexible placement: No wiring required; battery-powered. Can be placed in key areas prone to leaks (e.g., under kitchen sinks, beside washing machines, under water heaters, in basements, near water pipes).
• Low power consumption, long battery life: Low-power design. Uses a standard CR2477 battery for extended operation (typically 3-5 years, depending on alarm frequency and signal strength). Actively alerts when battery is low.
• Compact and slim: Small size, easy to place in narrow spaces.
• Easy installation: Simply place flat to secure; no tools needed.

III. Product Components List

• "AQUA" Water Presence Sensor main unit x 1
• CR2477 Coin Cell Battery x 1
• User Manual x 1
• (Optional) 3M Adhesive Pad x 1
• (Optional) Quick Start Guide x 1

IV. Installation & Placement

• Select Location: Identify high-risk points for potential leaks in your home or premises (e.g., under or behind washing machines, below dishwashers, inside water heater drain pans, under kitchen/bathroom sink cabinets, near A/C condensate drain lines, low points on basement floors, below pipe joints). Ensure the metal sensing electrodes on the bottom of the detector can contact potentially accumulating water flow or droplets.
• Installation Method:
  • a. Place Flat: Place the detector directly flat on a level surface in the area to be monitored, with the sensing surface facing down.
  • b. Adhere: Clean and dry the target surface. Peel off the adhesive backing and firmly attach the detector to the chosen location. Ensure the adhesive surface is flat and secure.
  • c. Important Note: When placing, ensure the metal sensing area on the bottom of the detector has no covering, and is not blocked or elevated by debris, otherwise effective leak detection will be impaired.

V. Maintenance & Care

• Regular Testing: It is recommended to test the device function monthly (touch electrodes with a damp cotton swab).
• Clean Sensing Electrodes: Regularly clean the bottom metal electrodes with a dry soft cloth to ensure they are free of dust and grime, maintaining sensitivity.
• Battery Replacement:
  • a. Replace the battery when the device indicates low battery (specific LED flash pattern/APP notification) or fails to respond during testing.
  • b. Open the battery compartment cover.
  • c. Remove the old battery, noting the polarity (+/-).
  • d. Insert a new CR2477 coin cell battery (ensure positive "+" side faces up).
  • e. Close the battery compartment cover. The device LED will flash.
  • f. Dispose of used batteries properly.
• Device Cleaning: Wipe the housing with a slightly damp soft cloth. Do not immerse or allow water to penetrate the device interior. Avoid using corrosive cleaners.

VII. Important Safety Information & Precautions

• For indoor use only. Avoid direct sunlight, high temperatures, high humidity (e.g., constant steam in bathrooms), and proximity to strong electromagnetic interference sources.
• This device is for detecting liquid water (leaks/overflows). It cannot detect water vapor, humidity, or prevent flooding.
• Alarms are for notification only and cannot stop leaks from occurring. Users are responsible for promptly addressing water leak issues.
• Do not disassemble, modify, drop forcefully, or crush the device.
• Use only the battery type specified in this manual and observe the correct polarity. Incorrect battery installation may damage the device.
• The sensing electrode area must not be coated with any paint, glue, stickers, or other insulating/conductive substances.
• Keeping the sensing electrodes clean and dry is crucial for proper operation.
• If the device will not be used for an extended period, remove the battery.
• Keep the device and battery out of reach of children and pets.
• This device is a supplementary safety tool and is not a substitute for regular inspection and maintenance of plumbing and equipment.
