This 12V diaphragm pressure pump is designed for reliable water transfer in various applications, including RVs, yachts, trailers, and off-grid cabins. It features a 3.5 gallons per minute (GPM) flow rate and a 55 PSI shut-off pressure, ensuring consistent water supply.
Please read this manual thoroughly before installation and use to ensure proper function and longevity of the pump.
2. Sikkerhedsoplysninger
Always observe basic safety precautions to reduce the risk of personal injury and damage to the pump or property.
- Elektrisk sikkerhed: Sørg for, at strømkilden passer til pumpens volumentage (12V DC). Disconnect power before performing any service or maintenance. Use appropriate fuses (e.g., 10A) in the power line.
- Væskekompatibilitet: This pump is designed for portable water, drinking water, salt water, and weakly acidic/other non-corrosive liquids.
- Temperaturområde: Do not transport corrosive or flammable liquids. Maintain liquid temperature between 0-60°C (32-140°F).
- Installation: Installer pumpen i et tørt, godt ventileret område. Beskyt mod frost.
- Beskyttelse mod tørløb: The pump is designed to run dry without damage, but continuous dry running is not recommended.

4. Produktfunktioner
The DC HOUSE 42 Series RV Water Pump is engineered with several features for optimal performance and user convenience:
- Høj ydeevne: Delivers a flow rate of up to 3.5 GPM with a shut-off pressure of 55 PSI, providing strong and consistent water flow.
- Stille drift: Equipped with an anti-vibration rubber base to significantly reduce noise during operation, ensuring a quieter environment.
- Automatisk trykafbryder: Features an on-demand pressure switch that automatically starts and stops the pump when a faucet is opened or closed, mimicking home water usage. The adjustment range for the shut-off pressure is 35-70 PSI.
- Bypass switch: Helps reduce pump cycling and strain on the pressure switch, contributing to a longer service life and smoother water flow at low rates.
- Holdbar konstruktion: Incorporates a 100% pure copper motor for enhanced durability and efficiency.
- Sikkerhedsmekanismer: Includes thermal protection to prevent overheating and is designed to run dry without sustaining damage.
- Alsidig anvendelse: Suitable for various mobile and off-grid water systems, including RVs, travel trailers, fifth-wheel trailers, motorhomes, yachts, and off-grid cabins.
5. Installation og opsætning
Følg disse trin for korrekt installation af din vandpumpe:
- Montering: Securely mount the pump in a stable location, preferably below the water tank level for easier priming. The pump can be installed in any direction/orientation.
- Strainer Installation: Firmly tighten the transparent strainer onto the pump's inlet port. This prevents debris from entering the pump.
- Hose Adaptors: Install the 1/2" barbed hose adaptors to the threaded MNPT on the pump's inlet and outlet ports. Use Teflon tape on threads to ensure a watertight seal.
- VVS tilslutninger: Connect your water lines to the barbed hose adaptors. Ensure all connections are secure and leak-free.
- Elektriske ledninger: Connect the pump to a 12V DC power source. Ensure correct polarity (red wire to positive, black wire to negative). Install a 10A fuse in the positive power line.
- Grunding: The pump is self-priming up to 9.8 feet (vertical lift). Open a faucet in your system to allow air to escape and the pump to prime.
6. Betjening
The DC HOUSE 42 Series RV Water Pump operates automatically based on water demand:
- Automatisk tænd/sluk: When a faucet is opened, the pressure in the water system drops, and the pump automatically turns on to supply water. When the faucet is closed, the pressure builds up, and the pump automatically shuts off at its set pressure (factory set at 55 PSI).
- Trykjustering: The shut-off pressure can be adjusted within a range of 35-70 PSI using the pressure switch L-rotator. Turning the screw clockwise increases pressure, and counter-clockwise decreases it. The factory set pressure usually meets most water needs without adjustment.
- Bypass-funktion: The integrated bypass switch allows for smooth water use at low flow rates by recirculating excess water back to the pump inlet, reducing rapid cycling of the pump.
7. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer optimal ydeevne og forlænger pumpens levetid:
- Rengøring af si: Periodically inspect and clean the transparent strainer to remove any accumulated debris. A clogged strainer can reduce pump performance.
- Vinterisering: In freezing conditions, drain all water from the pump and plumbing system to prevent damage from ice expansion. Follow your RV or boat manufacturer's winterization procedures.
- Forbindelser: Regularly check all hose and electrical connections for leaks or corrosion. Tighten as necessary.
- Opbevaring: If storing the pump for an extended period, ensure it is clean, dry, and protected from extreme temperatures.
