3) Suspend the lifter from appropriate hoisting equipment: 3.1) Select a crane and/or hoist rated for the Maximum Load Capacity plus the Lifter Weight. Note: Any lifter use must comply with all statutory or regulatory standards for hoisting equipment in your region. Rev 34.2/11-22 MRPT89AC: #35060... - Page 10 3.4) Use the hoisting equipment to remove the lifter from the shipping container. Avoid damaging the vacuum pads.

2..A “single piece” of material includes curtainwall assemblies, unitized glazing systems and similar construction units. 3..Vacuum pads made from a heat-resistant rubber compound can enable you to lift loads with higher surface temperatures. Contact WPG or an authorized dealer for more information. -

1..Although lifter use may be possible at higher elevation, lifting capacity is reduced whenever the lifter is unable to attain vacuum in the green range on the vacuum gauge. Contact WPG for more information. 2..Special provisions may allow the lifter to operate outside the specified temperature range. Contact WPG for more information. Rev 34.2/11-22... -

2) Use the hoisting equipment to lower the vacuum lifter gently onto a stable support. Then detach the hoisting hook from the lift point. Caution: Do not set the lifter on surfaces that could soil or damage vacuum pads. Rev 34.2/11-22 MRPT89AC: #35060... -
Page 25: Storing The Lifter
Transporting the Lifter Secure the lifter in the original shipping container with the original shipping materials or equivalent. 1..Storing the lifter without placing a support under the lift bar can result in damage to the tilt actuator. Rev 34.2/11-22 MRPT89AC: #35060... -
