Installation

2.4.1Handling With Skid

Always keep the Liebert Challenger ITR upright, indoors and protected from damage.

Do not use the extended rear door frame to lift the unit.

If possible, transport the unit using a fork lift; otherwise, use a crane with belts or cables, avoid- ing pressing on the top edges of the packaging.

If using a fork lift, make sure that the forks, if adjustable, are spread to the widest allowable dis- tance to still fit under the skid.

NOTICE

Do not attempt to lift the Liebert Challenger ITR with the extended rear door frame. Attempting to do so will damage the unit. Lift the unit only from its main base.

NOTICE

While on the skid, the Liebert Challenger ITR is too tall to fit through a standard height doorway (83 inches or 2108 mm tall). Any attempt to move the unit, while on the skid, through a standard doorway will damage the unit.

2.4.2Removal of Skid

1.Remove the plywood skirting that keeps the skid and unit in place.

2.Raise the Liebert Challenger ITR off the skid. Liebert recommends using a fork lift (see Figure 1) or similar machine to ensure that the unit is lifted properly.

NOTE

Lift the Liebert Challenger ITR only from its main base. Do not use the extended rear door frame to lift the unit.

3.Once the unit is raised, the skid can be removed.
