5. Инсталација и подешавање

Follow these steps for proper installation of your water pump:

  1. Монтажа: 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.
  2. Strainer Installation: Firmly tighten the transparent strainer onto the pump's inlet port. This prevents debris from entering the pump.
  3. 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.
  4. Водоводне везе: Connect your water lines to the barbed hose adaptors. Ensure all connections are secure and leak-free.
  5. Електричне инсталације: 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.
  6. Прајминг: 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.
Three-step guide for easy installation: 1. Firmly tighten the strainer. 2. Install barbed hose adapter to the threaded MNPT on the pump. 3. Install hose to barbed hose adaptors.
Step-by-step guide for installing the pump's accessories.

6. Операција

The DC HOUSE 42 Series RV Water Pump operates automatically based on water demand:

  • Аутоматско укључивање/искључивање: 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).
  • Подешавање притиска: 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.
  • Функција заобилажења: 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. Одржавање

Regular maintenance ensures optimal performance and extends the life of your pump:

  • Чишћење цедиљке: Periodically inspect and clean the transparent strainer to remove any accumulated debris. A clogged strainer can reduce pump performance.
  • Зимљење: 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.
  • Везе: Regularly check all hose and electrical connections for leaks or corrosion. Tighten as necessary.
  • Складиштење: If storing the pump for an extended period, ensure it is clean, dry, and protected from extreme temperatures.
