This connection provides the 230V 50 Hz electrical supply required to operate the Grant SpiraVAC
system, and switched live (to start the vacuum system when the contents switch in the hopper detects a
minimum pellet level).
To connect the hopper to the Vacuum unit:
•
Remove the wiring centre cover from the rear of the hopper.
•
Unclip the 6-way plug from diaphragm switch bracket.
•
Pass the 6-way plug lead through the grommet just below the wiring centre cover.
•
Set the selector switch on the diaphragm switch bracket to the ‘BULK STORE’ position. See
Figure 5-1.
•
Replace the wiring centre cover and fasten in place using the screws previously removed.
•
Connect the 6-way plug to the corresponding 6-way connector on the pre-wired flying lead fitted
to the Vacuum unit. Ensure that the plug and socket are fully pushed together until the small
catch clicks into place.
5.4 Connection of Vacuum Unit to Auger Unit
The 3-way plug and lead provides the 230V electrical supply from the vacuum unit to the remote auger
unit.
A corresponding 3-way connector is supplied fitted to the plug for connection of the cable to the remote
auger unit
The auger unit is supplied with a factory fitted isolator, which is pre-wired to the auger motor.
The connection
between the 3-way plug connection (at the vacuum unit) and the electrical isolator (on the
auger unit) must be made using a suitable size and type of cable, dependant on the cable length and the
route taken to the auger unit.
Where this is external to the building this cable must be of a suitable specification, e.g. UV stabilised PVC
sheath, SWA cable, etc. depending on the application.
Refer to Figure 5-5 for details of the plug and socket connection between the vacuum unit and the auger
unit.
