3. Installation

Before continuing, ensure you have completely read and understood this manual’s
Safety section, in addition to the safety information in the section(s) below.

3.1. Installation Safety

• Do not take chances with safety. The components can be large, heavy, and hard to handle.

Always use the proper tools, rated lifting equipment, and lifting points for the job.

• Always have two or more people installing the centrifugal fan.

• Make sure you have sufficient lighting for the work area.

• Tighten all fasteners according to their specifications. Do not replace or substitute bolts,

nuts, or other hardware that is of lesser quality than the hardware supplied by the
manufacturer.

3.2. Check Shipment

Inspect the centrifugal fan and accessories on receipt to ensure that all items have arrived and that none are
damaged.

A few basic items to check:

• Ensure no loose items or debris that can be drawn into the fan or dislodged by the fan discharge. Check the

interior of the fan as well.

• Turn the fan impeller/blade by hand to check for binding.

• Check the tightness of all nuts and bolts.

• Verify that the supply voltage is correct.

Report missing or damaged parts immediately to ensure that proper credit is received from Keho or your
distributor/dealer, and to ensure that any missing parts can be shipped quickly to avoid holding up the
installation.

Important

Do not use damaged components.

3.3. Handling the Fan

Lift the fan by the base, mounting supports, or lifting locations. Never lift a fan by the wheel, motor, motor
bracket, housing inlet, outlet, or any fan part not designed for lifting. A spreader should always be used to avoid
damage.

3.4. Storing the Fan Before Installing

Check the fan wheel for free operation and lubricate moving parts prior to storage if the fan is not to be placed
immediately into service. Inspect the stored unit periodically.
