New belts should be initially tensioned to 1.3 times the maximum running
tension settings outlined above. Belt tension needs to be adjusted five
minutes after these belts are fitted and the compressor is run, then again ten
minutes later. This will ensure that the belts have completed their initial
“stretch”. After this first fifteen minutes of operation, the belts should be
correctly tensioned to the table above.
