2. Cleaning and Inspection of Fans and Fan Space Polluted fans decrease efficiency AN Before performing any inspection work check whether the unit is switched off from the electric power supply Inspect and clean the fan impellers to remove possible dirt deposits Check the impeller to make sure that it is not out of balance Clean or brush off the fan motor It can also be cleaned by carefully wiping it with a damp cloth that has been dipped in a solution of water and dishwashing detergent Clean the fan space if needed 2 2 Plate Heat Exchanger in VERSO P PCF Air Handling Units When operating the air handling unit equipped with the plate heat exchanger unit control automation should have function of protection from frost Condensate can accumulate in a plate heat exchanger therefore it is essential to install siphons on the con densate drainpipes Depending on the unit construction plate heat exchanger section may have 1 or 2 siphones It is important to maintain cleanliness of the plate heat exchanger to change filters installed in the air handling unit on time if the heat exchan ger gets dirty to perform heat exchanger periodical cleaning The temper ature effectiveness of a dirty heat exchanger can diminish considerably E UAB AMALVA reserves the right to make changes without prior notice komfovent eee A 1 Plate heat exchanger 2 Support frame NN
