Installation
Mounting
Guardian GS,GR and GB air curtain units are
designed to be installed horizontally directly
over the door opening on the inside of the
building, against a wall or ceiling.
Care must be taken to allow
complete free air movement into
the inlet grilles of the unit to
ensure the correct working
operation of the air curtain. The
honeycomb outlet should be as
close to the top of the door as
possible and can be angled
towards the door from 0° to -5°.
Ensure to cover the entire door
width. See figure 8
Units can be mounted adjacent to each other
to cover the full door opening across wider
entrances.
The GS 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. Use the GR for
these types of applications
It is the sole responsibility of the
installer to ensure that the points
of attachment to the building are
sound.
Verification with the consultant/
architect or owner of the
building is recommended to
ensure that a sound, stable
installation can be achieved.

Electrical supply.
Units require a connection to 1 phase 230V
power supply only.
1000 and 1500 models consume 6kW and
2000 models consume 8kW.
The appliance must be connected to the
supply via an appropriate a switched fused
isolator, having a contact separation of greater
than 3mm. See technical data for fuse rating
on page 6
Once the covers have been removed, the
installation engineers terminal block is located
to the right hand side of the unit. This terminal
block is used for the connection of the mains
supply and additional controls, for example
door switch. Wire in accordance to the
diagram in the wiring section, on page 17
For safety reasons, a sound earth
connection must always be made
to the unit before it is put in to
use. The unit should be wired in
accordance with IEE Regulations
for the Electrical Equipment of
Buildings.
The display panel is connected to
the control panel (base unit) via a
pre-wired RJ45 cable maximum
length of 100m. (10m supplied as
standard). It is recommended that
this cable is run separately within its
own trunking to avoid external
interference.
