Check that there is enough space between the false ceiling and the
ceiling of the room to house the unit. Its height must be less than
the measured distance. Consult the corresponding chapter of the
Technical Catalogue for information on the unit measurements.
Before starting installation, plan the direction of the pipes and wiring required. Also bear in mind that there must be enough
space around the unit for installation and maintenance.
Install a service hatch near the pipe connection area and electrical junction box for installation and maintenance work.
