ROUTINE MAINTENANCEBEFORE UNDERTAKING ANY SORT OF MAINTENANCE OR CLEANING, DISCONNECT THE ELECTRICALPOWER SUPPLY TO THE UNIT, AND ENSURE THAT OTHER PEOPLE CANNOT RE-CONNECT IT .All equipment is subjected to wear out.The maintenance makes :1. keeps the unit efficiency2. the components last longer3. keeps their efficiency and limits breakdownsTherefore, it is fundamental to perform periodical checks:a few controls can be performed by the user(AUTONOMOUS MAINTENANCE) and they are mainlycleaning activities; otherwise, controls have to beperformed by specialized technicians (INSPECTIONS).The machine should have a log book used to keep trackof the performed controls. This will make fixing upbreakdowns easier.Take note of the date, type of control (autonomousmaintenance, inspection or fixing up), description of thecontrol, actions taken and so on.SERVICESParts subject to interventionSTRUCTURECheck the condition of the parts making up the structure.Paint so as to eliminate or reduce oxidation at the points in the unit where this problem may occur. Check that the panelling isfastened correctly. Poor fastening may give rise to malfunctions and abnormal noise and vibration.WATER EXCHANGERIt is very important for the exchanger to be able to provide the maximum thermal exchange. Therefore, it is essential for theinner surfaces to be clean of dirt and incrustations.Periodically check the difference between the temperature of the supply water and the condensation temperature. If thedifference is greater than 8°C–10°C it is advisable to clean the exchanger.M03Y40D9-01 09/04/10 page 37
