1. Safety
Install and Operate Fan Properly
Electrical controls and wiring shall be installed by a qualified
electrician and must meet the standards set by the National
Electric Code, Canadian Electrical Code and all local and state
codes. Fan shall be installed and maintained by a qualified
person familiar with the use and function of ventilation fans.
Disconnect and lock out all power sources before installing
wires/cables or servicing equipment.
Do not operate fan unless the motor is properly grounded.
Grounding can be achieved by wiring with a grounded conduit
or a separate ground wire attached to the motor’s ground lug.
Do not operate the fan by bypassing any safety device on
the unit.
Do not kink power cables and do not allow cables to come into
contact with oil, grease, hot surfaces or chemicals.
Motor overload protection shall be provided with each single
phase fan. A circuit breaker or slow blow motor type fuse shall
be used. A safety cut-off switch shall be located adjacent to
each fan.
Fans used to ventilate livestock buildings and other rooms
where continuous air movement is essential should be
connected to individual electrical circuits with a minimum of
two (2) circuits per room.
Installation of supplementary natural ventilation, back-up
thermostat and an alarm system on at least one cooling stage
is recommended. See diagram on motor nameplate and
information provided with fan control (if used) for connection
requirements.
