ACCURATE unit Raised floor Elastic gasket Elastic gasket OPERATING SPACE Access is from the front only for all models. This feature ensures easy access to all the main components in the unit for installation and periodical maintenance. Thanks to this feature, the units can be installed next to one another, or alternatively fitted in racks. - Page 15 OPTIONAL BASE MOULDING (A*O UNITS) The "OVER" units are designed for the connections to pass through the base of the unit; nonetheless, if there is no raised floor (units with intake from the rear or front), to simplify the connection of the pipes and cables, a base moulding must be used.
