7.0 Maintenance
Warning:
Dangerous Voltage. Before completing any form of
maintenance, ensure to isolate the unit from the mains and ensure all
supply circuits are disconnected.
This HRV unit may contain connections/signal wires from multiple electrical circuits.
ISOLATING THE CONTROL BOX WILL NOT ISOLATE ALL CIRCUITS WITHIN THE UNIT-
PLEASE ENSURE ISOLATION OF 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 trigger the auto-boost the system.
It is important to follow all guidelines relating to the maintenance of this HRV system to
ensure the unit continues to perform to the levels required.
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 online at
brookvent.co.uk
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
