that the motor is in compliance with the latest
edition of IEC 60204-1 and all electrical
connections are performed per IEC 60204-1,
this includes overcurrent protection.
Wire the motor and other electrical devices, such
as solenoid valves and temperature switch, to the
proper voltage and amperage as indicated on the
nameplate of the component being wired. Turn
the blower by hand after wiring is completed to
determine that there are no obstructions and that
the blower turns freely. Then, momentarily start the
blower to check the direction of rotation.
