Usage and product description
The air curtain is designed to prevent the entry of the cold ambient air into
a building and to reduce the thermal losses inside the premises. The
curtain is designed for the operation in premises with the ambient
temperature of from -10°C to +40°C and the relative humidity up to 80%
(at the tempe25°C).
The HSAC3 is manufactured from sheet steel coated with a high-quality
polymer. The ‘body’ of the unit contains heating elements, the fan modules
and the control switches. The fans draw in the air through the front
perforated grid of the body (2); the airflow passing through the heating
elements is heated, enters the ventilation assembly and released through
the air-relief nozzle (3) as the directed flow.
The HSAC3 also has a cool air circulation function in addition to ‘full’ and
’half’ power heating functions.
Before Installation
Select a suitable position for installation, allowing free access all around
and no closer than 100mm to the ceiling. For wide doorways, these units
may be mounted end-to-end, but allowing a suitable gap for the mounting
brackets if these are used, and for access and cable entry.
Installation
The HSAC3 may be fixed directly to the surface above an entry or for
greater operational flexibility may be installed using the supplied mounting
brackets.
