7.2 Requirements for the installation site
■
Make sure that the roof has sufficient load-bearing capacity and that the roof
frames correspond to the specifications in the design handbook.
■
Position the units according to the system layout. In doing so, ensure that the
units are aligned to one another, the minimum and maximum distances are
observed and that the correct coil connections are correctly positioned. Units
must not draw in exhaust air from other units as fresh air.
■
All air inlet and air outlet openings must be freely accessible. The supply air jet
must be free to spread out unhindered.
■
The access doors in the roof unit and the access panels in the below-roof unit
must be easily accessible.
■
The Air-Injector must be easily accessible.
■
A clearance of approx. 1 m is required on the side opposite the coil connections
for below-roof unit service and maintenance purposes.
