1. Introduktion
The Kohree 12V DC 7.0 GPM Smart RV Water Pump is designed to provide a consistent and efficient water supply for recreational vehicles (RVs), marine vessels, and other off-grid applications. This manual provides essential information for the safe installation, operation, and maintenance of your smart water pump. Please read this manual thoroughly before installation and operation.
2. Säkerhetsinformation
Observe the following safety precautions to prevent injury and damage to the pump or property:
- Always disconnect power to the pump before performing any installation, maintenance, or troubleshooting.
- Se till att pumpen är installerad i ett torrt, välventilerat utrymme, skyddat från direkt solljus och extrema temperaturer.
- Do not pump flammable liquids, gasoline, or other hazardous materials. This pump is designed for water only.
- Protect the pump and plumbing system from freezing temperatures to prevent damage.
- Se till att alla elektriska anslutningar är säkra och ordentligt isolerade för att förhindra kortslutning.
- Use appropriate fuse protection for the 12V DC power supply.
3. Produktfunktioner
- Smart Variable Speed Constant Pressure: Maintains stable system pressure by adjusting motor speed based on water demand, eliminating traditional pump cycling.
- Bluetooth-appkontroll: Adjust 3 constant pressure levels (1, 2, 3) and monitor pump status directly from your iOS or Android smartphone.
- Real-time Monitoring & Fault Alerts: Continuously monitors water pressure and temperature. Detects pipeline leaks, pressure sensor failures, low water temperature, and dry running conditions. Provides instant alerts to your phone.
- Omfattande skydd: Features built-in protection against dry running, thermal overload, overcurrent, high/low temperature, and high altitude operation.
- Tyst drift: Operates below 45 dB, enhanced by anti-vibration rubber feet and a shockproof iron plate. No accumulator tank is required due to the variable speed motor.
- Extended Pump Lifespan: Reduced pump cycling minimizes wear and tear on internal components, leading to longer service life.
- Breda tillämpningar: Suitable for various uses including RVs, boats, showering, dishwashing, car washing, and gardening.

5. Installation och installation
Följ dessa steg för korrekt installation:
- Montering: Select a dry, well-ventilated location for the pump. Securely mount the pump using its anti-vibration rubber feet to minimize noise and vibration. Ensure there is adequate space for plumbing connections and future maintenance.
- VVS-anslutningar:
- Identify the inlet and outlet ports on the pump. The inlet is typically marked with an arrow indicating flow direction towards the pump.
- Install the provided 50 mesh inlet strainer on the suction (inlet) side of the pump to prevent debris from entering.
- Apply Teflon tape to the threads of the 1/2 inch NPT barbed fittings before connecting them to the pump ports.
- Connect your water supply lines to the barbed fittings using the stainless steel clamps för att säkerställa en vattentät tätning.
- Ensure all plumbing connections are tight but do not overtighten.
- Elektrisk anslutning:
- Connect the pump to a 12V DC power source. The red wire is positive (+), and the black wire is negative (-).
- Ensure correct polarity to prevent damage to the pump.
- Install an appropriate fuse (not included, refer to pump specifications for recommended amperage) in the positive power line close to the power source.
- Secure all electrical connections and protect them from moisture.
- Förbereda pumpen:
- Ensure the water supply tank has water.
- Open a faucet in your system (e.g., kitchen sink) to allow air to escape.
- Turn on the pump. The pump will begin to draw water and expel air.
- Once a steady stream of water flows from the faucet, close the faucet. The pump should then build pressure and stop running.

6. Bruksanvisning
The Kohree Smart RV Water Pump offers intelligent, variable-speed operation.
- Ström på/av: Use the main power switch for your water system or the ON/OFF function within the Bluetooth app to control the pump.
- Automatisk drift: Once powered on and primed, the pump will automatically start when a faucet is opened and stop when all faucets are closed and system pressure is reached. Its variable speed technology ensures a consistent flow without rapid cycling.
- Pressure Adjustment (via App): Use the Bluetooth app to select one of the three constant pressure modes (1, 2, or 3) to optimize water flow and pressure according to your preference and system requirements.

7. Bluetooth-appkontroll
The Kohree Smart RV Water Pump can be controlled and monitored via a dedicated smartphone application.
- Appnedladdning: Refer to the specific instructions in the printed user manual for QR codes or links to download the official Kohree app for iOS and Android devices.
- Parning: Once the app is installed, ensure your pump is powered on and Bluetooth is enabled on your smartphone. Follow the in-app instructions to search for and pair with your Kohree Smart Water Pump.
- Övervakning: The app provides real-time data display, including:
- Voltage
- Amp Dra
- Vattentemperatur
- Vattentryck
- Current Constant Pressure Mode
- Inställningar: Adjust the constant pressure mode (1, 2, or 3) to suit your needs directly from the app interface.
- Fault Alerts: The app will display instant notifications for detected faults such as pipeline leakage, pressure sensor failure, low water temperature, or dry running, allowing for prompt action.

8. Underhåll
Regelbundet underhåll säkerställer optimal prestanda och förlänger pumpens livslängd.
- Inspektera anslutningar: Kontrollera regelbundet alla rör- och elkablar för läckor, korrosion eller lösa kopplingar. Dra åt vid behov.
- Rengör inloppssilen: The 50 mesh inlet strainer should be inspected and cleaned regularly to prevent blockages from debris, which can reduce flow and pressure.
- Vinterisering: If the pump will be exposed to freezing temperatures, it is crucial to drain the pump and the entire plumbing system completely. Running RV antifreeze through the system is also recommended.
- Allmän städning: Keep the exterior of the pump clean and free from dirt or dust. Do not use harsh chemicals for cleaning.
