L. Speed Settings
The Lo-Carbon PureAir Home
has two speed settings, ‘
Trickle
’ and ‘
Energy Recovery
’.
‘
Trickle
’ speed is automatically selected when the ambient loft temperature is
below 18
°
C
.
‘
Energy Recovery
’ is automatically selected when the ambient loft temperature is
between 18
°
C and 27
°
C
.
If the ambient loft temperature exceeds 27
°
C, the Lo-Carbon PureAir Home automatically switches to standby (no
airflow).
The speed settings on the Lo-Carbon PureAir Home are fully adjustable between 10L/s and 60L/s via the manual
speed setting option. Alternatively there are 5 Pre-set speeds, the speed settings relate to the number of bedrooms
with, for example, setting b03 being for a three bedroom dwelling. For the approximate flow rates at each setting see
Fig.10. The PureAir Home must be set to provide adequate ventilation according to Part F of the building regulations.
The table shows a set up representative of a good low resistance install. When F7 filters and/or a long duct
run are used it may be necessary to use the manual speed selection to meet the required flow rate.
It is the responsibility of the installer to ensure that appropriate speeds are selected.
M. SERVICING AND MAINTENANCE.
WARNING: THE POSITIVE VENTILATIION UNIT AND ANCILLARY CONTROL EQUIPMENT
MUST BE ISOLATED FROM THE POWER SUPPLY DURING THE INSTALLATION / OR
MAINTENANCE.
The fan motor uses sealed ball bearings, and does not require further lubrication.
Apart from filter change the Lo-Carbon PureAir Home contains no user serviceable parts.
Under normal conditions; i.e. away from main roads and industrial areas it is recommended that the filter is checked
annually and cleaned or replaced as necessary. Otherwise change as required.
The filter may be gently cleaned with a vacuum cleaner or washed in a soapy water solution and allowed to air dry
before re-fitting. Do not dry the filter in a tumble dryer.
When re-fitting make sure that the filter is fitted correctly. This will ensure that all the fresh air entering the
dwelling has passed through the filter first.
