1. General Information
Welcome to the new AB-2 Reznor air curtain
models. Local regulations may vary in the coun-
try of use and it is the installers respon-
sibility to ensure that such regulations are satis-
fied.
All installation, assembly, commissioning and
service procedures must be carried out by
suitably qualified competent persons to the
statutory regulations in the country of use.
When installing, commissioning and servicing is
undertaken on the air curtains specified in
these instructions, due care and attention is
required to ensure that working at height regula-
tions are adhered to at the mounting heights
specified.
All dimensions shown are in mm unless
otherwise stated.
The manufacturer reserves the right to alter
specifications without prior notice.
PLEASE READ this document prior to
installation to familiarise yourself with the
components and tools you require at the
various stages.
The primary reason for installing air curtains is
to prevent the influx of cold outside air through a
door opening into a heated area.
Typical applications include large despatch bay
doors in factories and warehouses, and internal
doors between areas of different temperatures.
Wider door openings can be accommodated by
bolting two or more units together.
Air curtains control the internal climate by
emitting an air stream with enough velocity to
meet the floor so creating an air barrier in the
door area. To prevent the ingress of outside
draughts, the discharge louvre is angled
outwards, so that the air leaving the building
meets the wind trying to enter, thus deflecting it.
(See diagrams below).
Reznor air curtains provide uniform air distribu-
tion across the full width of the door, keeping
heated or conditioned air inside the building and
stopping the ingress of cold air, draughts, and
dust.
This manual provides detailed information on
the installation of Reznor air curtains. It is es-
sential that these products are installed in ac-
cordance with these manufacturers in-
structions.
