3.3 To Adjust the Pressure Balance
(applicable to air handling units with rotary heat
exchanger)
3.3.1 General
The pressure in the extract airflow path should be slightly
lower than that in the supply airflow path to ensure cor-
rect air leakage direction and that the purging sector in
the heat exchanger will work correctly. This ensures that
extract air will not be carried over to the supply air.
The pressure balance in the unit should be adjusted when
the ventilation system has been fully installed, all the air
devices have been adjusted and the supply air and extract
air flows are as they should be while the air handling unit
is operating normally.

Two flow adjustment plates are supplied with the GOLD RX Top.
The version of the air handling unit, i.e. right-hand or left-hand,
is the factor that determines which of the flow adjustment
plates you should install in the unit. Install the correct flow
adjustment plate at its intended location inside the air handling
unit. Scrap the other plate. See the illustration above.
Remove the fixing screws and place the flow adjustment plate in
the grooves intended for retaining it. Tighten the fixing screws.
See the illustration above.
The pressure balance can be adjusted by blanking off holes in
the flow adjustment plate with the plugs supplied with the unit.
