SINGLE MOTOR—SINGLE FAN. MHF705 ONLY.
See Figure 3 for MH Fluid Cooler models MHF7103 thru MHF7107 with a
single motor per fan. Loosen specified hardware located at the top and bottom
of the motor support assembly before adjusting the jacking screws. Do not
remove the hardware—it is required to support the motor. Tighten
the hardware after adjustment. Ideal tension is the lowest tension at which the
belt will not slip under peak load conditions. Check tension frequently during
the first 24-48 hours of run-in operation. Over tensioning shortens belt and
bearing life. Keep belts free from foreign material which may cause slipping.
