Warranty
Applicable to units installed and used in the United
Kingdom. Airflow Developments Ltd guarantees the Aventa
in-line for 3 YEARS from date of purchase against faulty
material or workmanship. Warranty only covers the fan,
not the reinstallation of this if required. In the event of any
defective parts being found, Airflow Developments Ltd
reserve the right to repair or at our discretion replace
without charge provided that the unit:
1. Has been installed and used in accordance with the
fitting and wiring instructions supplied with each unit.
2. Has not been connected to an unsuitable electrical
supply.
3. Has not been subjected to misuse, neglect or damage.
4. Has not been modified or repaired by any person not
authorised by Airflow Developments Ltd
5. Has been installed in accordance with latest Building
Regulations and IEEE wiring regulations by a recognised
competent installer.
Airflow Developments Ltd shall not be liable for any loss,
injury or other consequential damage
,
in the event of a
failure of the equipment or arising from, or in connection
with, the equipment excepting only that nothing in this
condition shall be construed as to exclude or restrict
liability for negligence.
This warranty does not in any way affect any statutory or
other consumer rights.
Maintenance
SAFETY FIRST: ALWAYS ISOLATE THE FAN UNIT FROM THE
POWER SUPPLY BEFORE REMOVING THE COVER.
When installed according to these instructions the Aventa
in-line range is completely safe. The materials used do not
constitute a hazard.
Cleaning
The external housing of the fan can be wiped with a damp
cloth. Do not use household cleaners containing abrasives.
Note:
Always isolate the fan when cleaning. Never clean
any parts of the fan assembly by immersing in water or
using a dishwasher.
Warning
This appliance can be used by children aged from 8 years
and above and persons with reduced physical, sensory or
mental capabilities or lack of experience and knowledge if
they have been given supervision or instruction concerning
use of the appliance in a safe way and understand the
hazards involved. Children shall not play with the
appliance. Cleaning and user maintenance shall not be
made by children without supervision.
Recommended Best Practice
The Building Regulations 2010, Statutory Instrument Part
9, paragraph 42, imposes a requirement that testing and
reporting of mechanical ventilation performance is
conducted in accordance with an approved procedure.
Compliance with this requirement by an assessed and
registered ‘Competent Person’ should follow a ‘Best
Practice’ process and adopt air flow measurement,
Method A – The Unconditional Method – using a suitable
UKAS certified measuring instrument. Generically referred
to as a ‘Zero Pressure Air Flow Meter’ or ‘Powered Flow
Meter’.
Further information on this method is detailed in NHBC
Building Regulations Guidance Note G272a 10/13 and
BSRIA ‘A Guide to Measuring air flow rates’ document
BG46/2015
Installation with flexible ducting
Where flexible ducting is used the diameter must be
maintained with the minimum radius of a bend equal to the
diameter of the ducting. It is good ventilation practice that
the ducting is extended to 90% of its possible length in
order to maintain the best possible airflow. Ensure that
flexible duct connections are not over tightened to the fan
outlet spigot. To maximise airflow rigid ducting should be
used where possible. The fan and ducting should be
installed in accordance with the requirements of the
Domestic Ventilation Compliance Guide, part of the
Building Regulations.
Fan adjustment—Timer
The fan with timer function switches on when the voltage
is supplied to the LT or L1 terminal via an external switch.
After the voltage to the LT or L1 terminal is disconnected
the fan continues to run for the set overrun period,
between 1 and 20 minutes. The timer overrun is factory
set to 15 mins, it is adjusted by turning the potentiometer
(
T
) clockwise to increase and anti-clockwise to decrease.
