4 Requirements for Installation4.1 Mechanical Mounting4.1.1 Safety Requirements of Mechanical InstallationWARNINGHEAVY LOAD!Unbalanced loads can fall and loads can tip over. Failure to take proper lifting precautions increases risk of death,serious injury, or equipment damage.• Never walk under suspended loads.• Wear personal protective equipment.• Observe the weight of the unit and ensure that proper lifting equipment is used.• The center of gravity can be in an unexpected area. If that is not observed, the unit can fall over or tiltunexpectedly during lifting and transport. Check the center of gravity, before lifting the load.• When installing the filter, use the lifting eyes on both sides to lift the filter.Lift the filters using the dedicated lifting eyes. For enclosure X3-V3 to X8-V3 extra lifting eyes are placed in the centerline.CAUTIONFor filters with external fan, place hooks in the lifting eyes to lift the unit. Do not attempt to use lifting bars or othermethods with equipment going through the lifting eyes, since this could harm the fan.CAUTIONDo not lift the unit with the IP 21/NEMA 1 kit top cover mounted. This could damage the top cover or compromise thesafety during lifting.Illustration 4.1 and Illustration 4.2 show the recommended lifting methods for the different AHF types.Requirements for Installati...
