1.0 General description (all models)
1.1 Overview
1.1.1 The Silavent HRX2 appliance is a key part of a whole house ventilation system specifically
designed to improve indoor air quality in dwellings. The system is designed to provide
measured amounts of filtered, fresh air to living areas while constantly removing polluted,
stale air from bathing, cooking and washing areas at the same gentle rate.
Any available heat
in the outgoing stale air is recovered by a built-in heat exchanger and used to pre-warm the
fresh supply air.
1.1.2 A manual boost switch is provided to increase the ventilation rate, e.g. when cooking or
showering thereby maintaining a comfortable indoor environment.
1.1.3 The boost facility can also be triggered from a lighting circuit or by a range of sensors,
including humidity control and movement detection (supplied separately – see section 1.1.8)
1.1.4 The G3/EU3 filters in the appliance ensure that the fresh supply air is clean as it enters the
home. Additionally, the stale extract air is filtered to protect the heat exchanger from
unwanted contamination. These filters have to be cleaned regularly, depending on the levels
of pollution. The filters should be replaced when they start to show visible signs of wear.
1.1.5 This product is listed in SAP Appendix Q, therefore, part of the installation process requires
that an installation checklist is completed and submitted to the Building Control Body (BCB).
