How to use

Install the ARISTON Aures Slim Multi SM EU 7 close to the intended faucet following local electrical and plumbing regulations. Connect the unit to the cold water supply line and to a suitable electrical circuit rated for the heater’s power requirements. Adjust the faucet flow to match the heater’s low-flow operating range to achieve the desired outlet temperature. The heater operates on-demand: hot water is produced when the tap is opened and stops when the tap is closed.

Usage recommendations

For reliable operation, ensure electrical wiring and protection devices meet the heater’s power specification and that the installation location allows safe drainage and access for maintenance. Use the heater for single-point applications or low-flow fixtures; avoid attempting to supply multiple high-flow outlets simultaneously. If water hardness is high, consider installing appropriate water treatment to reduce scale buildup and maintain performance.
