7. Servicing
IMPORTANT Before commencing any service work on the Grant SpiraVac system, ensure that the
electrical supply from the pellet hopper is isolated, as follows:
•
Set the ‘VACUUM SYSTEM’ switch on the SpiraVac control panel to OFF.
•
Disconnect the 6-way connector between the pellet hopper and the vacuum unit.
This will enable the boiler to be left operating whilst the SpiraVac system is serviced.
On completion of the service work, re-connect the electrical supply from the pellet hopper using the
reverse of the above procedure.
