the values in Table 1. The blades have tapped holes to accept the
bolts.
Once the blades are installed, the fan should be checked for
interference with nearby objects by rotating it slowly by hand. The
fan should then be run at the lowest speed possible (generally around
10 Hertz) for a few minutes. The fan should be rotating in a counter-
clockwise direction when viewed from below. If the fan is rotating in
the wrong direction, refer to the control manual for instructions on
how to reverse. First, lock out the electrical connection. Reverse two
motor leads to change the direction of the fan. The fan speed should
then be increased to 60 HZ at 5 Hz intervals, running a minute or two
at each speed. At each interval, the fan should be checked for
interference and excessive vibration or rocking. If the fan rocks
significantly at any speed, additional bracing may be required. Call
the factory for assistance.
While in operation, there are a few issues to consider:
1. Avoid blocking air flow to areas where people will benefit from
it. This may involve moving obstructions or changing the
orientation of obstructions to take maximum advantage of the
airflow provided.
2. Try to avoid installing the fan below lights, if possible. The
blades passing below the lights may cause a flickering which
some people find annoying.
3. In winter, maximum benefits are usually obtained by running
the fan at about half speed. In summer it is usually
advantageous to run the fan at the highest speed which will not
inconvenience occupants by blowing around papers, etc...
