supply circuits are disconnected.
This HRV unit may contain connections/signal wires from multiple electrical circuits.
ISOLATING THE

ALL CONNECTING CIRCUITS BEFORE ACCESSING THE UNIT.
Examples of other connecting circuits
are: electric showers, lighting circuits, and humidistats. These connecting circuits may be used to

7.1
Filter Replacement
The filters of this HRV unit will usually need to be changed every 6 – 12 months depending on
occupancy/ use, and the type of environment the dwelling is located in (I.e. urban/ rural, and their
associated levels of airborne pollutants).
It is recommended that the filters are checked every 6 months. Replacement filters can be
purchased by contacting the Brookvent Head Office.
To change the filters, simply remove the filter covers from the front of the unit, replace the filters,
and replace the filter covers firmly.
Important:
Blocked filters will shorten the life span of your fan and increase the energy
consumption. Never run the HRV system without filters as this will allow unfiltered material to build
up in the heat recovery core and connected ductwork.
In new build properties it may be prudent to check/ change your filters after the first 3 months of
occupancy depending on the amount of residual ‘building dust’ present within the property
