PYROSTAR – SMOKE FAN F400-120 In compliance with the current norms, the machine should be installed only by a technical person qualified for this type of work. During installation, ensure that: - The machine is moved as given in chapter II.1. - The required personal protection devices are worn so as to avoid injuries caused by electrical and mechanical hazards (injuries by touching panels, sharp edges, etc.) - Electrical connections are made after the power supply has been shut off, in compliance with the...
PYROSTAR – SMOKE FAN F400-120 II.2. Space required for maintenance Generally speaking, it is desirable to provide access space of at least the width of the unit on the access side for maintenance. More specifically for the Pyrostar range, an extra 200 mm free space is needed on the opposite side to service side. II.3.

III.4 2 speeds motors (separate windings) 2 speeds – 1 voltage (separate windings) 400 V – 4/6 poles motors Low speed High speed Once wiring is done, check if the impeller is turning in the right direction.
PYROSTAR – SMOKE FAN F400-120 IV. IV BELT DRIVE IV.1. IV.1 Belt correct alignment At commissioning, check pulleys’ alignment (both motor and impeller pulleys !) along with belt tension. IV.2. IV.2 Belt tension Please refer to the following table for belt’s tension. I = pulleys axle spacing F = belt deflection P = force applied at I/2 (P = 40 N).
PYROSTAR – SMOKE FAN F400-120 IV.3. IV.3 Variable pulley settings The variable pulley allows to set airflow. 1 = fixed flange The variable flange can move on the threaded sleeve. To move the 2 = threaded sleeve flange, first unscrew the flange locking screw, then turn the flange. 3 = variable flange Screwing the flange will expend pulley’s diameter, ie higher airflow.
