Motors are multi-tapped and factory-wired for high speed.
Belt drive blower systems MUST be adjusted to the
specific static and CFM requirements for the appli-
cation. The Belt drive blowers are NOT set at the
factory for any specific static or CFM. Adjustments of
the blower speed and belt tension are REQUIRED.
Tighten blower pulley and motor sheave set screws
after these adjustments. Re-checking set screws
after 10-12 hrs. run time is recommended.
