Commissioning - Vent-Axia HR100R Installation And Servicing Instructions

5.0 Commissioning

5.1 Commissioning the System
Before starting to commission the system check
the following:
a) All ducting is in place and secured.
b) The wiring is secure and correctly connected.
c) The trap is in position, charged and will
enable efficient removal of condensate.
d) The unit is mounted appropriately in a
position not susceptible to movement or
damage.
The scope of the commissioning procedure
comprises:
1. Balancing the two airflows to achieve
maximum heat exchanger efficiency.
2. Adjusting the two airflows to obtain the overall
airflow rates and the individual terminal air flow
rates as specified on the air change schedule.
3. An airflow meter must be used to set the
correct airflows.
NOTE: The supply air terminal device is
directional and incorporates a deflector plate.
Ensure that the deflector plate is correctly
positioned so that the active part of the
terminal device is discharging to the room.
4. Set the control switch (NBSW or PCSW) to
normal speed or set the humidistat (HS6) at
maximum and check that air is flowing in the
correct direction at each terminal point.
5. Standard ceiling terminals type EV100 and
SV100 are adjusted by turning the central screw
and are locked in the "set" position by the
locknut.
