Installation Considerations

Rigging and Handling

Unit Shipping

1.Position rigging sling under wood shipping skid.

2.Use spreader bars to avoid unit damage.

3.When using a forklift, exercise caution to prevent unit damage.

4.Use the standard fork length to lift one end and drag or pull unit while skidding the opposite end.

5.The unit center of gravity will fall within center of gravity block at various locations depending on unit options.

6.Use hooks to lift fan section only. Do not hook into open channels to lift unit.

7.See unit nameplate for unit weight.

8.Do not stack units.

! CAUTION

Do not use hooks to lift unit or hook into open channels to lift unit. This could cause unit

damage.	Figure I-PC-7. Assembled modular unit proper rigging.
