MaintenanceGEA CAIRfricostarInitial check:Regular checks:Tensioning/renewing V-beltCarry out the initial check after approximately 50 operating hours..The subsequent checks depend on the operational load.– In event of normal operation (roughly 8 hrs a day), perform checks on a quarter ormore frequent basis.– Define shorter intervals between checks with greater number of operating hours.BeltprofilesDiameterof small pulley (mm)Force F(N/belt)SPZ 70 – 85 13 – 1986 – 155 15 – 23116 – 150 19 – 27151 – 200 25 – 24201 – 250 29 – 38SPA 112 – 150 25 – 34151 – 200 29 – 38201 – 250 35 – 44251 – 300 40 – 50SPB 180 – 224 40 – 52225 – 300 46 – 60301 – 400 55 – 76401 – 500 67 – 90Deflection x [mm]Tab. 9-3: High-performance narrow V-belt in accordance with DIN 7753504030201000 500 1000 1500 2000 2500 3000Distance between axes A [mm]DAMAGE TO UNIT AND NOTEAlways reduce the distance between the axes to the point where the V-belt can beplaced in the grooves without using force. The application of force during installationusing tyre levers, screwdrivers or similar tools is not permitted.If the V-belt pulleys have multiple grooves, all V-belts must be replaced. It is notallowed to combine V-belts made by different manufacturers in one set.V-belts do not require a great deal of care or maintenance. Belt wax and belt sprayare to be avoided.• Check the tension of the V-belt and check for wear and tear; tension or replace ifrequired.For V-belt tensioning via the pivoting motor base or replacement proceed as follows:• Slacken the lock nuts of the adjusting bolts.• Replace V-belt if necessary.• Check/adjust pulley alignment (see Fig. 9-1).• Tension V-belt (adjust using measuring device, see Fig. 9-1).• Tighten lock nuts.The deflection of the belt is approximately 5-20 mm when a load of P = 20-30 N isapplied, depending on the distance between the axes (see Fig. 9-1).56 PR-2006-0019-GB • Subject to modifications • Status 05/2009

Align both holes and screw in screws withouttightening.• Slide the pulley and sleeve along the shaft until it is as closeas possible to the motor or fan (to keep leverage small) andalign.
