Isolation switch
In accordance with the provisions of the EU Machinery Directive* a chimney fan
must always have an isolation switch fitted. The isolation switch must comply with national wiring
standards.
The isolation switch must be ordered separately, as it is not part of the standard
exodraft
chimney
fan delivery.
*Please refer to Machine Directive (2006/42/EF/-EEC/-EWG/-CEE) – Appendix 1 item 1.6.3 “Separation of the sources of
energy.
1.4
Commissioning of the chimney fan
The chimney draught must be checked when
commissioning the fan. The pressure differential switch
(PDS) might need adjusting during commissioning. The
PDS must be set so that the fail-safe system will cut out
when the volume of flue gases falls below a set level.
During such a test, all windows and doors must be
closed and any ventilation fans switched on. Please refer
to the relevant
exodraft
Gas Fan Controller Installation
Instructions for guidance.
As illustrated, remove the top cover and adjust the (PDS)
to the required value.
