CAUTION:
Ensure that the V-belt is aligned correctly. If it is not,
check for loose bolts.
The V-belt should not be too tight or too loose.
A belt which is too tight may break bearing or cause
gas to leak from the shaft seal. A belt which is too
loose slips, thereby causing the belt cut.
After completing the compressor installation and
testing the system operation, check and adjust the ten-
sion of both V-belts again.
