TYPICAL ACTUATOR FITTING / REMOVAL
The removal is the reverse of the above as the actuators are pre-fitted. Removal should
only be carried out in the event of failure and following discussion and approval from an
Evinox engineer.
In the event that the pressure parameters need to be checked during operation, temporary
binder points can be installed for testing purposes by an Evinox engineer to ensure they
are within the max / min tolerance, the following data can be checked:-
For 91L ¾” – ModuSat TP 40-10, 50-10 & 60-10 HEATING &
For 91H ¾” – ModuSat TP 40-10 & 50-10 DHW
*
Please note that the binder points are not supplied with the valve as standard. Temporary binder
points can be installed by an Evinox engineer should any checks be required.
