Followthe procedures outlined below to correctfy set and measure belt tension
1.Lay e slraight edge across the top outer surface of the belt drive from pulley to sheave
2.At the cen_.arof the span. perpendicular !o the bait. apply pressure to the outer surface of the bell with a tension gauge Force the belt to the deflection indicated in the table at right Compare the reading on the tension gauge to the following t.able
t0.9, | I .0 | I 0.o | J |
Ensure the pulley and sheave are properly aligned and fhe motor anchor screws are adequately retightened prior to restarting the
compressor
CAUTION Improper pulley/sheave alignment and belt tension can result in motor overload, excessive vibration, and premature belt andlor bearing failure
To prevent these problems from occurring, ensure
the pulley and sheave are aligned and belt tension is satisfactory after Installing new belts or tensioning existing belts
TANK INSPECTION
The life of an air receiver tank is dependent upon several factors including, but not ltmlted to, operating conditions, ambient environments, and Ihe level of matntaoanCer The exact effect of
these factors on lank life is difficult to predict; therefore,
if the tank has not been inspected within the first 10 years of compressor service, the tank must be taken out of service until it has passed inspection Tanks that fail to meet requirements must be replaced
_, WARNING Failure to replace a rusted air receiver tsnk could result in air receiver tank rupture or explosion, which could cause substantial property damage,
severe personal injury, or death, Never modifyor repair tank. Obtain replacement from service centarr
