4.2.3 INSTALLATION OF FREE COOLING PLENUM ABOVE THE UNIT
Depending on the type of plenum, they are attached in two dierent ways:
Unit with sheet metal structure: With bolts inserted in the relative holes.
Unit with aluminium prole structure: With brackets.
With bracket-mounted models, the brackets need to be attached to the unit’s aluminium uprights with self-drilling screws.
The brackets should be attached, in a central position, to each side of the unit.
Securing the brackets
Do the following to install Free Cooling plenums:
1) Place a seal on the plenum proles (rubber or equivalent material with minimum 5 mm thickness) and position the plenum
on the unit, taking care to line the proles up.
2) Attach the unit to the plenum with duly-sized self-drilling screws or bolts (models without clamping brackets).
