The casing internals must be free of any foreign objects which can damage the impeller blades. The appliance maintenance and repair is allowed only after power cut-off and full stop of the rotating parts. Misuse of the appliance or any unauthorized modification are not allowed. The appliance is designed for connection to power mains in compliance with the technical data table. The appliance is rated for permanent operation. Take steps to prevent ingress of smoke, carbon monoxide and other combustion products into the room through open chimney flues or other fire-protection devices. Sufficient air supply must be provided for proper combustion and exhaust of gases through the chimney of fuel burning equipment to prevent back drafting. The maximum permitted pressure difference per living units is 4 Pa. The transported air must not contain any dust or other solid impurities, sticky substances or fibrous materials. The appliance is not rated for operation in a flammable or explosive medium. Fulfil the operation manual requirements to ensure a trouble-free and long service life of the appliance. TRANSPORTATION AND STORAGE RULES Transportation of the appliance is allowed by any vehicle provided the appliance is transported in the original package and is protected against weather and mechanical damages. Use hoist machinery for handling and transportation to prevent possible mechanical damages of the appliance. Fulfil the requirements for transportation of the specified cargo type during cargo-handling operations. Store the appliance in a dry and cool place in the original packing. The storage environment must not be subjected to any aggressive and/ or chemical evaporations, admixtures, foreign objects that may provoke corrosion and damage connection tightness. Store the appliance in an environment with minimized risk of mechanical damages, temperature and humidity fluctuations. Do not expose the appliance to the temperatures below +5 °C and above +40 °C . Connection of the appliance to power mains is allowed after the appliance has been kept indoor for minimum two hours. MANUFACTURER’S WARRANTY The appliance complies with the requirements according to the EU norms and directives, to the relevant EU-Low Voltage Equipment Directives, EU- Directives on Electromagnetic Compatibility. We hereby declare that the appliance complies with the essential protection requirements of Electromagnetic Council Directive 2004/108/ EC, 89/336/EEC and Low Voltage Directive 2006/95/EC, 73/23/EEC and CE-marking Directive 93/68/EEC on the approximation of the laws of the Member States relating to electromagnetic compatibility. This certificate is issued following test carried out on samples of the product referred to above. Assessment of compliance of the product with the requirements relating to electromagnetic compatibility was based on the following standards. The manufacturer hereby warrants normal operation of the appliance over the period of two years from the retail sale date provided observance of the installation and operation regulations. In case of failure due to manufacturing fault during the warranty period the consumer has the right to exchange it. The replacement is offered by the Seller. If case of no confirmation of the sale date, the warranty period shall be calculated from the manufacturing date. The manufacturer shall not be liable for any damage resulting from any misuse of or gross mechanical interference with the appliance. The manufacturer is not responsible for the damages resulted due to the use of third party equipment or to third party equipment. WARNING Do not dispose in domestic waste. The appliance contains in part material that can be recycled and in part substances that should not end up as domestic waste. Dispose of the appliance once it has reached the end of its working life according to the regulations valid in your country. WARNING The appliance is not allowed for use by children and persons with re- duced physical, mental or sensory capacities, without proper practical experience or expertise, unless they are controlled or instructed on the product operation by the person(s) responsible for their safety. Supervise the children and do not let them play with the product. ! KOMFORT_EC_DE v1(1)_EN.indd 3 07.08.2015 12:39:48 4 www.blaubergventilatoren.de KOMFORT EC DE Fig. 1. Unit design and operating logic DESIGN The casing made of double-skinned aluzinc panels, internally filled with mineral wool layer of 20 or 25 mm for heat- and sound-insulation. The casing has fixing brackets with vibration absorbing connectors for easy installation. The spigots for connection to the air ducts are located at the side of the unit and are equipped with rubber seals for airtight connection to the fair ducts. The service panel ensures easy access to the unit internals for service works including cleaning, filter replacement, etc. The unit is equipped with high-efficient external rotor EC motors and centrifugal impellers with forward curved blades. The integrated EC motors have the best power consumption to air capacity ratio and meet the latest demands concerning energy saving and high-efficient ventilation. EC motors are featured with high performance, low noise level and totally controllable speed range. The impellers are dynamically balanced. The KOMFORT EC DE400/700/1100 models are equipped with high- efficient counter-flow polystyrene heat exchangers with a large surface area. The KOMFORT EC DE2000/4000 models are equipped with high-efficient cross-flow aluminium heat exchangers with a large surface area. The air flows are fully separated within the heat exchanger. Odour and contaminants contained in the extract air are not transferred to the supply air flow. Heat recovery is based on utilization of heat energy contained in the extract air stream for heating up of supply air stream. Extract air transfers most of its heat to the intake air flow. Heat recovery reduces heat energy losses in cold seasons. In summer the heat exchanger performs reverse and transfers accumulated cold from cool extract air stream to warm supply extract air stream. This contributes to better performance of the air conditioners in ventilated premises. The electronic frost protection system based on bypass and heater is used to prevent the heat exchanger freezing in cold seasons. The bypass damper is opened and the heater is turned on automatically according to temperature sensor readings. Cold intake air passes by the heat exchanger and is warmed up to set temperature in the heat exchanger. Synchronously extract air that passes by the heat exchanger is used for its defrosting. After the freezing danger is over the bypass damper is closed, the heater is turned off and the unit reverts to the normal operation mode. The drain pan under the heat exchanger block is used for condensate collection and drainage. The unit is equipped with an electric heater for operation during cold seasons at low outside temperature. The integrated electric heater is activated to warm up supply air flow if set indoor air temperature may not be reached by means of heat recovery only. Smooth heat output control ensures automatic supply air temperature maintaining. The unit is equipped with two integrated overheat protection thermostats, one actuated at +60 °C with automatic restart and the other one actuated at +90 °C with manual restart. The KOMFORT EC DE400/700/1100 model includes a built-in G4 (optionally F7) pocket supply filter and a G4 cassette extract filter for efficient air filtration. The KOMFORT EC DE2000/4000 model includes a built-in G4 supply and extract cassette filters for efficient air filtration. The unit incorporates an integrated control system with a wall-mounted control panel and sensor display. The standard delivery set includes a 10 m cable for connection of the unit and the control panel. KOMFORT EC DE400-1.5 ... KOMFORT EC DE1100-3.3 KOMFORT EC DE2000-12 ...
