4. Instalacja
Proper installation is crucial for the safe and efficient operation of your water heater. Refer to local plumbing and electrical codes before beginning installation.
4.1 Wybór miejsca
- Choose a location that is protected from freezing temperatures.
- Ensure the mounting surface is capable of supporting the full weight of the water heater when filled with water (approximately 100 lbs for 12 gallons).
- Allow adequate clearance for maintenance and service.
4.2 Połączenia hydrauliczne
- Connect the cold water inlet (blue) and hot water outlet (red) to your plumbing system using 3/4 inch NPT fittings.
- Install the provided T&P relief valve into the designated opening on the top or side of the water heater. Route the discharge pipe from the T&P valve to an open drain.
- Use sealing tape on all threaded connections to prevent leaks.
4.3 Połączenia elektryczne
- Przed przystąpieniem do wykonywania jakichkolwiek podłączeń elektrycznych należy upewnić się, że zasilanie jest odłączone od wyłącznika automatycznego.
- Connect the water heater to a dedicated 120V~60Hz electrical circuit with appropriate overcurrent protection.
- Follow the wiring diagram provided on the unit or in the full manual.
4.4 Napełnianie podgrzewacza wody
- Before connecting power, open a hot water faucet in your home to allow air to escape.
- Otworzyć zawór dopływu zimnej wody do podgrzewacza wody.
- Once water flows steadily from the hot water faucet, the water heater is full. Close the hot water faucet.

This image illustrates a 3-step installation process: 1. Install the three-prong plug on the right side above the heater. 2. Attach the one-way valve to the water inlet. 3. To reduce leaks during pipe connection, add a rubber sealing gasket to the end of the threads.

This diagram demonstrates two application scenarios: a 'Single Faucet Unit' where the heater supplies hot water directly to one faucet, and a 'Booster Unit' where it functions as a booster for an existing water heater system, ensuring continuous hot water during peak usage.
5. Instrukcja obsługi
Once installed and filled with water, you can begin operating your VEVOR water heater.
5.1 Włączanie
Turn on the electrical power supply to the water heater at the circuit breaker.
5.2 Regulacja temperatury
Use the rotary knob on the front panel to set your desired water temperature. The temperature adjustment range is typically 95°F-167°F (35°C-75°C).
5.3 wskaźnik LED
The LED indicator light will illuminate when the heating element is active and turn off once the set temperature is reached.

This image highlights the convenient operating system, featuring a temperature control knob for setting water temperature between 95°F-167°F and an LED indicator to display the heating status.
6. Konserwacja
Regular maintenance ensures optimal performance and extends the lifespan of your water heater. Always disconnect power before maintenance.
6.1 Opróżnianie zbiornika
Periodically drain the tank to remove sediment buildup. This should be done at least once a year, or more frequently in areas with hard water.
- Wyłącz zasilanie podgrzewacza wody.
- Zamknij zawór dopływu zimnej wody do podgrzewacza wody.
- Podłącz wąż do zaworu spustowego znajdującego się na spodzie zbiornika i skieruj go do odpowiedniego odpływu.
- Otwórz zawór spustowy i odkręć kran z ciepłą wodą w domu, aby umożliwić dopływ powietrza do zbiornika, co ułatwi odpływ wody.
- Once drained, close the drain valve and hot water faucet, then refill the tank as described in the installation section before restoring power.
6.2 T&P Valve Inspection
Test the T&P relief valve annually by lifting the lever. Water should discharge from the drain pipe. If no water discharges, or if the valve does not reseat properly, replace it immediately.
6.3 Kontrola pręta anodowego
The anode rod protects the tank from corrosion. Inspect and replace the anode rod every 3-5 years, or more often if water conditions are aggressive.
