TB3190 - 875 CASSETTE MOTOR AND COWL CHANGE

TB3190 - 875 CASSETTE MOTOR AND COWL CHANGE

12.01.2017

875 cassette motor and cowl change

This change affects all CC875 and CWC 875 models from serial number 0960650.

In order to improve the consistency of airflow, the relationship between the fan and cowl has been altered:-
The cowl profile is enhanced, and the colour changed from cream to grey.
The motor windings have been respecified to maintain design airflows.
Capacitors are now  5mfd across the range (CWC 875 previously had 4mfd capacitors).

No changes will be perceived by the installer, but the old motor should not be mixed with the new cowl, and vice versa, otherwise incorrect airflows may result.  
To avoid any mismatch, new spare motors will always be sent with a compatible grey cowl and a 5mfd capacitor.

The position with spares is:-
