Setup and Installation
The VENUS Magma Plus 15GV water heater comes with an installation kit, flexible hose, and wall fixing card. Professional installation is highly recommended to ensure proper functioning and safety.
Included Components:
- 1 Storage water heater unit
- Flexible hose (for water connections)
- User manual (this document)
- Installation Kit (mounting brackets, screws, etc.)
- Wall fixing card (for precise mounting)
Installation Steps (Overview):
- Site Selection: Choose a suitable wall location, ensuring it is strong enough to support the filled water heater and is close to water inlet/outlet points and a power source.
- Mounting: Use the provided wall fixing card to mark drilling points. Securely mount the water heater to the wall using the installation kit.
- Water Connections: Connect the cold water inlet and hot water outlet pipes using the flexible hoses. Ensure all connections are tight to prevent leaks. Install a pressure relief valve if required by local codes.
- Electrical Connection: Connect the water heater to a dedicated, properly grounded electrical outlet. Ensure the voltage matches the appliance's requirements (230 Volts).
- Filling the Tank: Before switching on, open a hot water tap in your home to allow air to escape and the tank to fill completely with water. Close the tap once water flows steadily.
- Initial Check: Inspect all connections for leaks and ensure the appliance is securely mounted.

Operating Instructions
Once the water heater is correctly installed and filled with water, you can begin operation.
- Power On: Switch on the main power supply to the water heater. The indicator light (if present) will illuminate.
- Set Temperature: Use the temperature control knob, located at the bottom of the unit, to set your desired water temperature. The Capillary Thermostat allows for precise adjustment.
- Heating Cycle: The water heater will begin heating the water. The heating time will vary depending on the initial water temperature and the desired setting. For a full tank, it may take approximately 30-55 minutes to reach maximum temperature (around 75°C).
- Automatic Cut-off: The thermostat will automatically cut off power to the heating elements once the set temperature is reached, saving energy. It will reactivate when the water temperature drops.
- Power Off: When hot water is no longer needed for an extended period, it is recommended to switch off the power supply to the water heater.

Maintenance
Regular maintenance ensures the longevity and efficient performance of your water heater.
- Cleaning: Periodically wipe the outer body with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Scale Guard Technology: The integrated Scale Guard Technology helps reduce mineral deposits. However, in areas with extremely hard water, periodic descaling by a qualified technician may still be beneficial.
- Pressure Relief Valve: Check the pressure relief valve annually to ensure it is not blocked and is functioning correctly. Refer to the installation guide for specific instructions on testing this valve.
- Anode Rod Inspection: The sacrificial anode rod protects the tank from corrosion. It should be inspected and replaced periodically (typically every 1-3 years, depending on water quality) by a service professional.
- Professional Servicing: It is recommended to have your water heater inspected by a qualified service technician at least once every two years.
