General Notes and Abbreviations Note According to the German energy-saving act EnEV, starting from 1.2.2002, boilers with outputs in excess of 25 kW must be equipped with either switchgear-equipped heating pumps for automatic performance control or electronically controlled pumps. Pump replacement Please refer to the current Wilo heating pumps replacement guide for more detailed information. Wear and tear <strong>Pumps</strong> or parts of pumps are subject to wear in accordance with state-of-the-art technology (DIN 31051 / DIN-EN 13306). This wear may vary depending on operating parameters (temperature, pressure, water condition) and the installation / usage situation and may result in the malfunction or failure at different times of the above-mentioned products / components including their electrical / electronic circuitry. Wearing parts are all components subject to rotary or dynamic strain, including electronic components under tension, in particular: - seals / gaskets (including rotating mechanical seals), seal ring Wilo Catalogue A2 - <strong>Glanded</strong> pumps - bearings and shafts - stuffing boxes - capacitors - relays / contactors / switches - electronic circuits, semiconductor components, etc. -impellers - wearing rings / wearing plates We do not accept liability for faults or defects arising from natural wear and tear.
