4.1. Comprobaciones previas a la instalación
- Confirm water pressure is within the recommended range (check specifications).
- Ensure sufficient space under the sink for the unit and future filter changes.
- Cierre el suministro principal de agua antes de comenzar la instalación.
4.2. Pasos de instalación (generales)
- Instalar el grifo: Drill a hole (if necessary) in the sink or countertop and mount the dedicated drinking water faucet.
- Conectar al suministro de agua fría: Install the water supply adapter to the cold water line under the sink.
- Instalación del soporte de drenaje: Attach the drain saddle valve to the drain pipe to allow wastewater discharge.
- Monte la unidad de filtro: Place the main filter unit in the desired under-sink location.
- Conecte la tubería: Connect the appropriate tubing from the water supply adapter to the filter inlet, from the filter outlet to the faucet, and from the filter's drain port to the drain saddle.
- Limpiar el sistema: Slowly turn on the water supply. Allow the system to flush for at least 10-15 minutes to remove air and carbon fines. Check for leaks.
5. Instrucciones de funcionamiento
The Aquaphor RO-70S system operates automatically once installed. It uses a multi-stage filtration process to provide clean drinking water.
5.1. Filtration Process
- Prefiltración: The CarbFiber Block technology in the pre-filters removes organic impurities, heavy metals, and chlorine, filtering particles down to 5 microns. This stage protects the RO membrane.
- Membrana de ósmosis inversa: The RO-50S membrane acts as a barrier against toxic substances, heavy metals, pesticides, bacteria, and viruses, ensuring high-purity water.
- Post-filtration: A final filter polishes the water, improving taste and odor.
