Removing transportation fastener of fan
1. FC upflow unit
The motor base of the fan is designed with a semi-free self-tension structure to minimize the fan operation noise and
prolong the belt life. During the transportation, to protect the semi-free structure from failing or collapsing due to
resonation, the upflow unit is especially fastened with bolts (left and right symmetrical, one at each side), as shown in
Figure 2-35. You should cut the binding string on the belt and remove the four fixing bolts before the power-on
operation; otherwise, the fan could be damaged and even cause personal injury. It is necessary to hold the motor
firmly while you remove the fixing bolts.
Cut the binding string on the belt.
Note
When you open the front door of unit, you will see a warning label concerning bolt removal on the sealing panel of the fan.
Remove the bolts by following the preceding instructions.
