Introduction - Vent-Axia HR100W Installation And Servicing Instructions

1.0 Introduction

1.1 Description
1. The HR100W, HR100WH and HR30W units are
"through the wall" heat recovery ventilators, for use
in areas such as kitchens, bathrooms and single
occupancy bedrooms.
2. The units are fitted with twin impeller and
heat exchanger arrangements which
simultaneously supply and extract air while
transferring heat from the stale exhaust airflow
to the fresh intake airflow. This provides up to
70% heat recovery from the stale extracted air.
A boost speed facility is available for periods
when higher air change rates are required.
3. Installation and maintenance for all three
Fig. 1
units is the same, therefore the majority of this
booklet is based on the standard HR100W unit
(Fig. 1). For additional information on the other
units, please refer to Additional Information
(Section 6.0).
