GMM is not applied:Service intervals according to Service and Maintenance Schedules (SMS)tables in combination with operating conditionsWarning!GMM is not used: The running hours mentioned in the SMS tablesshould only be used as a reference for maintenance intervals.The number of running hours mentioned in the SMS tables have to beadjusted accordingly depending on the operating conditions of thecompressor (speed, evaporating temperature, condensingtemperature, refrigerant, start frequency, capacity control steps, etc..This means that the service intervals could be significantly different.The running hours mentioned in the tables are based on a single stagecompressor running at -10oC/+35oC, NH3 at nominal speed. In thiscase the SMS factor = 1, in all other cases the maintenance intervalshave to be adjusted accordingly.3.5 LegendWarning!These operations cover routine maintenance and are meant as a guideonly. Lack of maintenance, frequency of stop/starting, extremeoperating conditions etc could lead to accelerated wear.General;The service and maintenance schedules use the codes as explained in the tablebelow;8 Time dependent on pollution.9 Consult your oil supplier.MAINTENANCESMS FACTOR0089288gbr_1130.10.2017 41
