Mounting
ACM units should be installed horizontally directly
over the door opening. It is recommended that the
air curtain is installed on the inside of the building,
against a wall or ceiling.
Care must be taken to allow complete free air
movement into the inlet grille of the unit to ensure
correct working operation of the air curtain.
The discharge opening should be as close to the
top of the door as possible and to cover the entire
door width.
When mounted over a standard shop doorway the
unit should be fitted as low as possible (but not
less than 2.3 metres from ground level).
A single unit ACM900SE6/SA will provide
reasonable coverage for an internal doorway, a
single ACM1200SE7/SA unit will provide coverage
for an invalid doorway width up to 1200mm, and
an ACM1500SE9/SA unit is suitable for door
widths up to 1.5m wide. Units can be interlinked

across wider entrances, provided that a gap of
20mm is maintained between units.
The unit shall be mounted so that the airflow is
not obstructed by any part of the doorframe with
a minimum clearance distance to ceiling of
30mm.(Fig.4)
These units are designed for surface mounting
and should not be placed into a ceiling void,
due to possible obstruction of airflow and
difficulty in routine cleaning and maintenance.
