RED INDICATOR NEON
The red INDICATOR NEON indicates one of three operating conditions, depending on the setting of the
‘VACUUM SYSTEM’ switch, as follows:
With the ‘VACUUM SYSTEM’ switch is set to OFF
When the INDICATOR NEON is lit it indicates that the vacuum system is on standby, i.e. it will NOT
operate automatically when the contents switch in the pellet hopper detects the minimum level of pellets.
If the INDICATOR NEON is not lit, this indicates a problem with the power supply to the boiler and/or the
Vacuum system. Please contact your installer or service engineer for assistance.
With the ‘VACUUM SYSTEM’ switch is set to ON
When the INDICATOR NEON is not lit it indicates that the vacuum system is ready to operate
automatically when the contents switch in the pellet hopper detects the minimum level of pellets.
If the INDICATOR NEON is lit it indicates that there is a fault with the vacuum system. Please contact your
installer or service engineer for assistance.

8.4 Starting the system
Switch the ‘VACUUM SYSTEM’ switch to ON. The vacuum system will operate until the hopper is filled
with pellets up to the level of the trap door of the cyclone. In this condition the trap door will be prevented
from closing by the pellets. This is intentional as further operation of the vacuum system is not required
with this amount of pellets in the hopper.
The SpiraVac system is now operational and will automatically operate to re-fill the pellet hopper when the
pellet level in the pellet hopper falls to the minimum level.
NOTE
Every time the ‘VACUUM SYSTEM’ switch is switched OFF and then back to ON, the SpiraVac system will
operate and fill the pellet hopper up to the level of the counterweighted trap door of the vacuum unit,
irrespective of the pellet level in the hopper at that time.
8.5 ’24 Hour’ operation
The Grant SpiraVac system will always automatically operate and fill the hopper every 24 hours starting
from the time it is first switched on using the VACUUM SYSTEM ON/OFF switch on the control panel. This
is the SpiraVac system ’24 Hour’ operating mode.
The ’24 Hour’ operating mode can be set to automatically fill the pellet store with sufficient pellets, at a
