(or accessory set) is not acceptable.
C. Any structural changes or device
modifications on one’s own are not permitted.
D.
Protect the appliance’s housing from mechanical damage.
E. Before installing
– it is important it examine the load carrying capability of the structural
elements of the building where the roof fan shall be installed. Unsure mounting could re-
sult in uncontrolled device detachment, its damage and hazard to people in the vicinity.
F. Do not use the fan for conveying the air containing viscous impurities
that could deposit on the device surface, especially on the impeller.
G. Neither use it for forwarding the air with aggressive pollutants which
will destructively effect the device structure.

Noise measurement has been conducted:
–
at maximum volume flow,
–
at the TK silencer attached at the fan inlet (silencer length 370 mm for WP-3-E/Ex
and 1000 mmm for the other fans from the series,
1. Maximum temperature of the conveyed air is +
60ºC,
whereas maximum temperature within the work zone +4
0ºC.
2.
Maximum dustiness of the conveyed air should not exceed 0,3 g/m
