Safer field move

Read the isolator data sheet. Asymmetrically loaded fans require isolators of different stiffness on each corner to maintain level. Verify the deflection rating and orientation of each pad before setting the equipment.

Ask Foreman

Can you verify this before I keep going? I’m looking at: Installing vibration isolators upside down on a fan that has asymmetric loading. What’s the approved correction for this job?

Do not

Do not hide, force, cover, or “make it work” if this affects safety, access, airflow, rated assemblies, supports, equipment, or inspection. Stop and verify the approved correction.
