8.0 Commissioning
8.2 Balancing the system
Note: It is important that a suitable
anemometer is used to balance the
system therefore giving the required
ventilation rates to each room.
1. Set the appliance running on normal speed.
2. Make a preliminary adjustment of all the duct
inlet and outlet louvres.
Note: The supply air terminal is directional
and incorporates a deflector plate. Ensure
that the deflector plate is correctly
positioned so that the active part of the
terminal is discharging to the room.
3. Check the flow rate and adjust if necessary
the extract valve furthest from the appliance.
4. Check the flow rates and adjust if necessary
the remaining extract valves.
5. Repeat the flow checks and adjust until the
extract system is balanced.
6. Check the flow rate and adjust if necessary
the inlet valve furthest from the appliance.
7. Check the flow rate and adjust if necessary
the remaining inlet valves.
8. Repeat the checks and adjust until the system
is correctly balanced.
Note: If the flow rates have been achieved
with all the louvres nearly closed, it may
be possible to reduce the fan speed and
re-adjust the louvre settings.
8.3 Instruct the user
Instruct the user in the operation of the
appliance. Hand over these instructions, giving
advice on the necessity for regular servicing of
the filters and heat exchanger.
Note: It is important that any door or
cupboard front covering the MVHR unit is
easily removable by the user as access for
regular cleaning of the air filter and heat
exchanger is required.
