INSTALLATION MANUAL
Ambient Air Curtain
Model SR-AMC
General
This user’s guide is meant for the installer and for the end user. It’s a
reference to operation and installation of an SR-AMC air curtain. For safety
sake and to guarantee correct operation, it is essential that you read this
manual thoroughly before starting
the installation, including all tips and warnings.
Keep this manual with the appliance and see to it that it is included when the
appliance is moved or sold, to ensure that everyone is informed about the use
and safety aspects of the device throughout its lifetime.
1.1 Description
The Air Curtain Module consists of a metal casing with a bladed fan and motor
on top, secured by a fan guard. There is a discharge nozzle with louvers on
the opposite side, which enables the airflow to be directed in the desired
direction. An air curtain consist of multiple Air Curtain Modules with an
assembly set.
1.2 Function
The air curtain functions as an invisible door/segregation and has insulation
properties, this can reduce energy losses up to 80% with an open door. The air
curtain can be used with chilled or heated spaces. In most circumstances an
air curtain is used to minimize heat losses with an open door, it could also
be used as a segregation between a non or limited heated space and warmer
heated space.
For example between a storage space and workshop. The airspeed can be
controlled by an optional 5 stage speed controller, which can be used to
adjust airspeed for different heights (widths), difference in forced
ventilation (negative pressure) within the building or for variation in
weather influences. The switch has a stage that cuts off power to the
installation. (stage 0).
The air curtain can be activated through the use of a door switch, which
triggers a relay which in turn sends the power to the air curtain.
1.3 Warranty
Operation/installation of appliances not according to this manual will void
the warranty. It’s not allowed to change the specifications or to make
modifications of any kind, on this appliance.
Technical Data
2.1 Table with data
Because the SR-AMC air curtain consist of multiple modular sections, a
variation of different widths or heights (ver- tidal installation) can be
constructed. Theoretical there isn’t a limit to the amount of coupled modules,
but every 10 connected modules must be succored/supported at each end.
If more than 10 modules are used there needs to be a another power source,
because the internal wiring is designed for a maximum amperage of 10A.

2.2 Pre-check
Before installation, please check (i.e. on the data badge) if the appliance is
in accordance with the order and whether it suites the local and present
provisions ( electrical supply etc.). Also check after installation that
operation of the appliance can’t form any hazard caused by moisture and dust,
or can cause injuries to people.
Installation
3.1 Suspension
Every unit has 4 ‘pop nuts’ at each corner, in the illustration on page 3, the
dimensions are depicted with the notification H-H.
By using these ‘pop nuts’ one can mount the air curtain to the wall or ceiling
with brackets or M10 studs. These are not included (as standard).
The coupled modules have to be suspended or supported at each end. The maximum
non-supported or suspended coupled units is set at 10 modules (5m) to prevent
sagging.
3.2 Calculating number of modules
Each module is 500mm long. One can find the number of modules with resulting
length in the data table on page3.
The air curtain has to be wider than the door opening to provide an effective
barrier and prevent air ingress at the ends (see Fig.2).
Calculation: Measure the width of the door in cm and divide with 50, the
resulting number is the minimum number of modules. Almost always there is an
extra module needed for sufficient overlap.
3.3 Positioning
Make sure the air curtain has undisrupted flow of intake air and blown air,
there should be a minimum distance of 0.5m between ceiling or overhead door.
Horizontal mounting is preferred above vertical mounting, as this enables the
air curtain to also serve as a recirculation fan and the air stream will be
warmer than on floor level.
The side of the air stream should be as close as possible to the edge of the
door opening, the further the air curtain is placed away from the door opening
the less effective it becomes.
The distance to the wall with our horizontal brackets is variable between
41-368mm, with the vertical brackets this is between 0-300mm.
The maximum mounting height is 4.5m. In case of vertical mounting the maximum
door width for one air curtain is 4.5m. For other dimensions ask your supplier
for advice.
With use of the adjustable louvres, one can change the direction of the air
stream, the louvres may not be set at extreme angles, because this has a
negative effect on the efficiency of the fans.

Electrical Connection
WARNING! Before starting installation make sure that that electrical
group you are working on, has been shut off. The appliance must be earthed.
4.1 230Vac supply
The installation must comply with all applicable local and/or national
standards i.e. NEN 1010.
There should be a suitable electrical group with a main fuse. There is an
electrical diagram further on in this guide.
The electrical supply is 230Vac (50 Hz) with earth.
4.1.2 Isolation switch or power plug
The appliance has to be equipped with a 230 Volt isolation switch or power
plug. This switch should be suitable for the maximum accumulated amperage.
This switch should disconnect phase and neutral (not earth) and have at least
an 3mm contact opening.
Switches or power plugs must be accessible at all times.
For power supply the unit has been provided with a 3-pole power plug (female).
The installer should connect a 3-wire mains cable and a power plug to it.
4.2 Connection options
4.2.1. Connection without speed control
With the interference of an isolation switch or power plug the air curtain can
be connected to the mains. If the connection is made the fans will run
continually at full speed. See sect6.2
4.2.2. Connection with door switch
The air curtain can be activated as the door opens. This can be done with the
use of a door switch, which powers the relay of the relay box (article GA4100)
and activates the air curtain. See sect6.3.
4.2.3. Connection with speed control.
The airspeed can be adjusted with the 5-step switch for different heights
(widths), difference in forced ventilation (negative pressure) within the
building or for variation in weather influences. Step 0 can be used to shut
off the power.
Function:
The 5-stage speed control is installed in between the power source. Depending
on the chosen stage, the fan will turn fast or slowly.
Before installation consult the manual of the 5-stages switch. See sect6.2 and
6.3.
Setting, Operation and Maintenance
WARNING!: Before starting maintenance make sure that the power group you
are working on has been shut off!
The appliance should have earth!
5.1 Operation
With the 5-step switch one can adjust the airspeed on ground level, as
explained in sect4.2.
The airspeed on ground level should not be too low otherwise the air curtain
coverage cannot withstand any wind load. Too high airspeed at ground level
will lead to unnecessary turbulence and excessive sound. The ideal flow
profile is depicted in the illustration below (Fig. 5), one can roughly check
this by feeling with the hands, or ‘tuft testing’ with a strip of paper to
visualize the airflow profile. Of course an anemometer would be best. If there
is a strong wind load on the door opening, one can turn up the airspeed.
The air curtain isolates the interior space, thus it can be used in summer.
Not only to repel the heat , but also to prevent the ingress of flying
insects.
ATTENTION!: Do not set the louvers in an (sloping) angle greater than
20°. This will decrease the air output.

5.2 Maintenance
In spaces with heavy dust it might be necessary to clean the fan guard with
compressed air once a year. If the fan guard is covered with severe dust the
fan will have diminished suction capabilities.
