If it is necessary to take air from a remote source, such as in a vacuum application, a vacuum kit will be
necessary. The piping should be at least the same diameter of the blower inlet. For distances greater than
20 feet (6 m) the pipe diameter should be enlarged to reduce inlet restriction. Excessive restriction will
reduce the efficiency of the blower and elevate its discharge temperature. The piping used should also be
corrosion resistant, and free of scale and dirt. The inlet should be covered to keep out precipitation, insects,
and small animals. Vacuum kits are available.
4.6 MOTOR AND ELECTRICAL CONNECTIONS
All electrical wiring should be performed by a qualified and licensed electrician in compliance with NEC and
IEC standards and local codes as applicable. Be sure to investigate the local requirements before installing
your Qube. For the Drive Motor, refer to the data plate on the drive motor for wiring details. The power
supply should be adequate and free of parasitic loads that will cause an undervoltage condition during the
operation of the blower. Otherwise, nuisance electrical shutdowns will result.
WARNING
The motor and connections shall be protected to assure that product and
environmental condensation does not come in contact with the electrical
connections.
NOTE
It is the responsibility of the installer to assure that the motor is in compliance
with the latest edition of IEC 60204-1 and all electrical connections
performed per IEC 60204-1, this includes over current protection.
