4.0 Commissioning
4.1.1 Overview
4.1.2 When the wiring connections have been checked, and it is safe to do so, switch on the mains
supply and check that the system is operating correctly. The appliance should switch between
low and boost speeds using the manual boost switch (see 1.1.2).
4.1.3 Airflow rates will need to be set at each room’s air valve in accordance with the 2010
Domestic Ventilation Compliance Guide to balance the system. Airflow measurements should
be performed using a calibrated airflow measuring device and the results recorded in litres
per second (l/s) onto the Inspection Checklist and Airflow Measurement Test Sheet contained
within the 2010 Domestic Ventilation Compliance Guide. The most common method uses a
vane anemometer, or similar, placed in a hood which completely covers the air valve to
measure the extract or supply airflow rate. The instrument should be calibrated annually by
returning the instrument to a UKAS accredited calibration centre and be capable of achieving
an accuracy of ±5%.
4.1.4 Each room airflow rate will need to be recorded on the Inspection Checklist and Airflow
Measurement Test Sheet. A completed copy must accompany these instructions and be
handed over to the dwelling owner upon completion of the installation.
4.2 System balancing
•
Fully open all of the air valves
•
Switch the system to boost
•
Close all internal and external doors and windows
•
Measure the total air volume of the extract valves (wet rooms)
•
Remove the rubber tamper-deterrent cap and using a small screwdriver, adjust the
‘boost’ control on the wiring centre to achieve the total design extract rate
•
Adjust individual room air valves to achieve the individual room design extract rates
•
Switch the system to low
•
Measure the total air volume of the supply valves (habitable rooms)
•
Remove the rubber tamper-deterrent cap and using a small screwdriver, adjust the
‘low’ control on the wiring centre to achieve the total design supply rate
•
Adjust individual room air valves to achieve the individual room design supply rates
•
Using the lock nuts fitted to the air valves, lock in position
•
Refit the rubber tamper-deterrent caps to the lid of the wiring centre
