This document is the operating and installation instructions for the Electronic instant water heater MDX 3..7. The product provides economically warm water.
The CLAGE MDX3..7 is an electronic instant water heater designed for single‑sink use. It heats water on demand and is pre‑set to an outlet temperature of about 38 °C for safe hand washing. The unit automatically shuts off when flow stops or water temperature limits are reached.
The manual details safe installation in a frost‑free room, required connections, adjustment of water flow and temperature, and troubleshooting. Only qualified technicians should perform installation and maintenance, and the appliance must be grounded and protected from frost. This manual is written in German.
