Setup and Installation
Installation should only be performed by a qualified professional. Ensure all local plumbing and electrical codes are met.
Pre-Installation Checks:
- Verify that the electrical supply matches the appliance's requirements (3000W).
- Ensure adequate water pressure (up to 6.5 bars).
- Select a suitable wall-mounting location, away from direct water splashes.
Installation Steps:
- Mounting: Securely mount the water heater to a sturdy wall using appropriate fasteners.
- Water Connections: Connect the cold water inlet and hot water outlet pipes. Ensure all connections are watertight. Connection pipes are typically purchased separately.
- Electrical Connection: Connect the appliance to a dedicated, grounded electrical circuit.

Operating Instructions
Follow these steps for safe and effective operation:
- Power On: Ensure the water heater is filled with water (as per installation step 4). Switch on the main power supply to the appliance.
- Heating Indicator: The heating indicator light will illuminate, signifying that the water is being heated.
- Hot Water Ready: Once the water reaches the set temperature (up to 75°C), the heating indicator light will turn off. The water is now ready for use.
- Using Hot Water: Open the hot water tap. The instant water heater will continuously heat water as it flows through.
- Power Off: After use, switch off the power supply to the water heater.
Note: For optimal performance, avoid using the instant water heater for filling large volumes like bathtubs, as it is designed for quick, smaller quantities of hot water.
Maintenance and Care
Regular maintenance ensures longevity and efficient performance of your water heater.
- Cleaning: Disconnect power before cleaning. Wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Descaling: In areas with hard water, scale formation can occur. Periodic descaling by a qualified technician may be necessary to maintain heating efficiency.
