Installation

Levelling

The unit once positioned shall be levelled. This ensures that the unit has an air tight seal between the InRak and any
adjacent server racks. Unit need to be level to ensure that any condensate collected is disposed of correctly.

Brush Seal

Levelling foot adjustment

Note: The brush seal compresses when the feet are adjusted creating a tight seal to the floor. The seal is supplied loose

for easy fitment.
