7. ELECTRICAL. wiring and hook-up should be done by a qualified
electrician. Follow wiring diagram on motor. Make sure that the
voltage at the motor corresponds to the motor name plate. The motor
manufacturer will guarantee the motor only if the voltage is within 10%
of the rating. Use appropriate safety device such as a magnetic starter
with overload heaters.
IMPORTANT: Check for correct blower rotation, clockwise, as indicated
by arrow on blower housing by starting and stopping motor and viewing
either blower wheel (if duct is not already connected to discharge), motor
cooling fan (located at rear end of TEFC motors) or motor shaft and pulley
(belt driven units). Incorrect rotation will substantially decrease blower
efficiency. If rotation is incorrect: on 3 phase motors switch any 2 leads:
on single phase follow motor nameplate wiring diagram.
IMPORTANT: DO NOT run the motor for extended periods of time until
the ductwork is in place and connected. If you do, you will overload the
motor. DO NOT run the collector with either drum cover off, doors or
hopper slide gate open. This will also overload the motor.
8. DUCTWORK- If ductwork is not properly designed and sized, the
suction of the dust collector will be greatly reduced as well as
increased chance of fire or explosion. The designer of the ductwork
must be experienced with dust collection systems. The ductwork
should have shortest possible runs, long sweep elbows which have a
radius that is 1-1/2 times the diameter of the elbow and at least 45°
branches from the main duct. Use duct sealant and rivets to connect
the pipes. Do not use plastic pipe because static electricity can cause
a fire or explosion.
