Somewhere between storing your winter gear and setting up for spring, the paper manual for your De'Longhi DR‑155 disappears. And now you're staring at a machine that can dehumidify, heat, or do both — but you're not entirely sure which button does what. The De'Longhi DR‑155 is a combined appliance: a dehumidifier and a space heater in one unit. But without the original documentation, unlocking its full potential feels like solving a puzzle.
Chances are you ended up here because you searched for download pdf manual or free user guide and landed on page after page of broken links and shady file hosts. That's exactly why a proper manual repository exists. It cuts through the noise and gives you the original, unaltered PDF — no subscriptions, no pop‑ups, no credit card required.
This guide walks you through the essentials of the De'Longhi DR‑155 based on the official manual. You'll learn how to operate each mode, what all those buttons actually do, and how to fix the most common problems without calling a technician. Keep the PDF handy, bookmark this page, and let's turn that appliance confusion into confident operation.
What You're Actually Looking At: A Combined Dehumidifier
The DR‑155 is not just a dehumidifier. It's a combined dehumidifier that integrates three distinct functions in one portable chassis: dehumidifying only, heating only, or both simultaneously (called "Combi Dryer" mode). The heating element delivers 1,600 W at maximum power or 800 W in economy mode. When you run dehumidifying and heating together at full tilt, the total draw climbs to 1,990 W — not pocket change, but acceptable for a portable unit.
Understanding this versatility is the first step to getting the machine to behave the way you want. If you only need to dry out a damp basement, you run it in dehumidify mode. If a room is cold and humid, you run both functions together. And if you just want warmth on a chilly evening, you switch it to heating mode. The manual lays this out clearly, and once you know the logic, it becomes second nature.
The appliance also features two fan speeds: MAX for maximum airflow and faster dehumidifying/heating, and ECON (economy) for quieter operation and lower energy consumption. The relevant pilot light on the control panel illuminates to show which speed is active.
