6.0 Commissioning
1. For the required air flow rates please refer to the design
specification for the property, follow 2.4, or refer to building
regulations ADF 2006/2010.
2. The unit is supplied with independent control for both normal
and boost airflows. (see fig. 9).
3. Correct commissioning is essential to ensure the ventilation
air flowrates are met. It also ensures the unit is not over
ventilating and causing excessive power consumption.
4. Commissioning should be carried out in accordance with
building regulations document “Domestic ventilation
compliance guide”. A calibrated moving vane anemometer
and hood will be required to carry out commissioning.
5. Adjustment valves should be locked in place to prevent
further adjustment.
6. Once commissioned the home owner / tenant should be
informed that the unit should not be adjusted as it will have
a detrimental effect on the indoor air quality and could result
in condensation and mould growth. The label covering the
control has an adhesive panel which should be removed post
commissioning to prevent tampering.
