following guards must be installed, according to installation type:


Type D installation: no fixed guards installed on intake and exit.

the duct connections made, as follows:

Type A installation: no guards (no ducts are connected);

Type B installation: fixed guard fitted on exit duct;

Type C installation: fixed guard fitted on intake duct;

Type D installation: fixed guards fitted both on intake and exit ducts.

Always verify all safety aspects of the installation type chosen.
CAUTION:
Unless otherwise specified by contract, the fan and guards are suitable for installation as a
single unit, and must not be subjected to effects of fluid dynamics caused by other machines
installed in the same fluid movement system.
