WARNING
– Verify that the air exhaust at the top of the collector is not
blocked. Verify that materials are not stored over the exhaust opening.
Stand clear of fan exhaust during rotation.
2. Start fan motor and visually verify that the blower wheel is turning in the
direction indicated by the rotation arrow on the blower housing. Incorrect
rotation direction will cause up to a 60% decrease in rated air volume while
requiring more than its rated horsepower. If the blower rotation is incorrect,
rotation must be corrected by switching any two leads (3 phase only).
