Installation Guide
The ACTIVA Inferno geyser is designed for wall-mounted installation. For safety and optimal performance, professional installation is recommended.
Pre-Installation Checks:
- Ensure the installation location is suitable for a wall-mounted appliance and can support its weight when full.
- Verify that the electrical supply matches the geyser's requirements (230 Volts, 3000 Watts).
- Confirm availability of proper water inlet and outlet connections.
Installation Steps:
- Mounting: Securely mount the geyser to a sturdy wall using appropriate fasteners. Ensure it is level.
- Water Connections: Connect the cold water inlet (blue marking) and hot water outlet (red marking) pipes. Use thread seal tape for leak-proof connections.
- Pressure Release Valve: Install the pressure release valve as per local plumbing codes.
- Electrical Connection: Connect the geyser to a dedicated, properly grounded electrical outlet. Ensure the power is off during this step.
- Fill the Tank: Before switching on, open a hot water tap in your home and allow water to flow through the geyser until a steady stream comes out, indicating the tank is full. Close the tap.

Care and Maintenance
Regular maintenance ensures the longevity and efficient performance of your ACTIVA Inferno geyser. Always disconnect the power supply before performing any maintenance.
- External Cleaning: Wipe the outer body with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Descaling: Depending on water hardness in your area, mineral deposits (scale) can build up inside the tank and on the heating element. It is recommended to have the geyser descaled by a qualified technician annually or bi-annually.
- Pressure Release Valve Check: Periodically check the pressure release valve to ensure it is not blocked and functions correctly. Consult a technician if you notice any issues.
- Leak Inspection: Regularly inspect all water connections for any signs of leaks. Tighten connections if necessary.
