Step 6 – Put in new fan box
Place new fan box up on the primary filter making sure that the fan is up and that
it is properly seated on to the primary filter.
Place the secondary filter on top of the fan box and make sure that it is properly
seated onto the edges of the fan box.
Now make your connections:
 The left fan power supply wire
 Air sampling tube
 The right fan power supply wire to the next fan (if applicable)
Make sure the micro switch settings of the new fan are the same as that of the old fan.
 Check the micro switches on the front of the replacement fan.
Based on their position from left to right:
Fan #1 should be
On, Off, Off, Off = Down, Up, Up, Up
Fan #2 should be On, Off, Off, On = Down, Up, Up, Down
Fan #3 should be On, Off, On, Off = Down, Up, Down, Up
Fan #4 should be On, Off, On, On = Down, Up, Down, Down
Fan #5 should be On, On, Off, Off = Down, Down, Up, Up
If you need to adjust the
micro switch, you may use a very small slotted screw driver
or even a pencil. Make your adjustments by putting light pressure on the micro
switch to either move it up (off) or down (on) .
Step 7 – Follow the Reconfiguration Process
Now follow the Reconfiguration Process at step #3. If after you have completed the
