KOMFOrt ultra d 105(-A) www.blaubergventilatoren.de All operations described in this manual must be performed by qualified personnel only, properly trained and qualified to install, make electrical connections and maintain ventilation units. Do not attempt to install the product, connect it to the mains, or perform maintenance yourself. This is unsafe and impossible without special knowledge. Disconnect the power supply prior to any operations with the unit.
KOMFOrt ultra d 105(-A) www.blaubergventilatoren.de PURPOSE The unit is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafes, conference halls, and other utility and public spaces as well as to recover the heat energy contained in the air extracted from the premises to warm up the filtered stream of intake air. The unit is not intended for organizing ventilation in swimming pools, saunas, greenhouses, summer gardens, and other spaces with high humidity.
KOMFOrt ultra d 105(-A) www.blaubergventilatoren.de TECHNICAL DATA The unit is designed for indoor application with the ambient temperature ranging from +1 °C up to +40 °C and relative humidity up to 60 % without condensation. In cold, damp rooms, there is a possibility of freezing or condensation inside and outside the casing.
KOMFOrt ultra d 105(-A) www.blaubergventilatoren.de DESIGN AND OPERATING PRINCIPLE The unit has the following operating logic: extract air from the room flows into the unit, where it is filtered by the extract filters, then air flows through the heat exchanger and is exhausted outside by the exhaust fan. Air from outside flows into the unit, where it is cleaned by the supply filters. Then the air flows through the heat exchanger and is directed to the room with the supply fan.
KOMFOrt ultra d 105(-A) www.blaubergventilatoren.de MOUNTING AND SET-UP BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN OBJECTS (E.G. FOIL, PAPER). WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR. The unit may be suspended on threaded rods or may be rigidly fixed to a horizontal surface by anchor bolts. Fasteners for fan mounting should be ordered separately.
KOMFOrt ultra d 105(-A) www.blaubergventilatoren.de CONDENSATE DRAINAGE The KOMFORT Ultra D 105 units are equipped with an enthalpy heat exchanger and do not require condensate drainage. The KOMFORT Ultra D 105-A units are equipped with a drain pan for condensate collection and removal. Temperature differences between supply and extract air flows in heat recovery units lead to condensate formation. Condensate is collected in the drain pan and is removed outside by the drain pipes.
KOMFOrt ultra d 105(-A) www.blaubergventilatoren.de CONNECTION TO POWER MAINS POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN. THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL. • • • • The unit is designed for connection to power mains with the parameters specified in the “Technical data” section.
KOMFOrt ultra d 105(-A) www.blaubergventilatoren.de TECHNICAL MAINTENANCE DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS! MAKE SURE THE UNIT IS DISCONNECTED FROM POWER MAINS BEFORE REMOVING THE PROTECTION! Maintenance operations of the unit are required 3-4 times per year. They include general cleaning of the unit and the following operations: 1. Filter maintenance (3-4 times per year). Dirty filters increase air resistance in the system and reduce supply air volume.
KOMFOrt ultra d 105(-A) www.blaubergventilatoren.de 2. Heat exchanger maintenance (once a year). Some dust may accumulate on the heat exchanger block even in case of regular maintenance of the filters. To maintain the high heat recovery efficiency, regular cleaning is required. Maintenance of the heat exchanger in KOMFORT Ultra D 105-A units: Press out on the latches. Remove the service panel. 1 2 Maintenance of the heat exchanger in KOMFORT Ultra D 105 units: Press out on the latches.

Even in case of regular maintenance of the filters, some dust may accumulate inside the fans and reduce the fan performance and supply air flow. Clean the fans with a soft brush or cloth. Do not use water, aggressive solvents, or sharp objects as they may damage the impeller. 4. Technical maintenance of condensate drainage system (four times a year).
KOMFOrt ultra d 105(-A) www.blaubergventilatoren.de TROUBLESHOOTING PROBLEM The fan(s) do(es) not get started. Cold supply air. Low air flow. Noise, vibration. Water leakage (only for the KOMFORT Ultra D 105-A models). POSSIBLE REASONS TROUBLESHOOTING Make sure the power supply line is connected correctly, otherwise troubleshoot a connection error. Extract filter clogging. Clean or replace the extract filter. Check the heat exchanger for icing. Switch the unit off The heat exchanger is frosted.
