General product information
Models
• GS Surface mounted model
• GR Recessed mounted model
• GB Bulkhead mounted model
Three sizes
• 1000mm
• 1500mm
• 2000mm
All electrically heated
The new design allows for quick and easy
access to the control panel and the installers
terminal block, the GS range has two access
panels on the 1000, three on the 1500 and
four on the 2000. The GR has hinged access
panels which can be removed with ease
These models require a single phase (230v)
electrical supply.
All units have fans capable of providing
standard & high capacity air duties.
Units are designed for versatile installation,
options of wall mounted, recessed within a
false ceiling, fitted in a bulkhead, or on drop
rods in front of glass fronted entrances.
A wall mounting bracket is available as an
optional extra. Units can be mounted adjacent
to each other to cover the full door opening
across wider entrances.
All models are supplied with a program panel
and 10m length of RJ45 communication cable.
A 100m cable is available at an additional cost.
The program panel allows the user to control
either a single air curtain, or a network of up
to 16 air curtains.
Easy programming the end users simply select
whether they require the heat on or off, the
required fan setting (1,2 or 3 speed), and the
outlet temperature setting
Options for BMS compatible via Modbus
communication can be linked to optional
external thermostat for proportional control in
various set temperatures
Health and safety
Before installing, carefully read the instructions
and follow the processes explained by the
manufacturer
Check that the temperature ranges given
and those of the location match. The
appliance must be powered with a voltage
corresponding to the value shown on the
rating plate.
Ensure that anchoring points are suitable for
the weight and loading of the product and if
required, add suitable reinforcement to the
anchoring points area.
Installing, programming, commissioning,
and maintenance of these products must
only be carried out by suitably qualified and
trained technicians and in full compliance of
all applicable regulations and current best
practices.
Due consideration should be taken for
workplace safety, risk assessments and waste
disposal.

Requirements
Clearance distances
For installation and maintenance clearances,
please see the information on page 8 for the
GS models, page 6 for the GR models and
page 10 for the GB models.
Electrical
For full electrical loadings, please refer to
the technical data section on page 6 of this
manual.
It is recommended that the electrical supply
to the base unit in the air curtain is via
an appropriate switched isolator, fitted in
accordance with the regulations in force in the
country of use and must be via a fused isolator
having a contact separation of greater than
3mm in all poles.
For safety reasons a good earth
connection must ALWAYS be
made to the heater and control
box.
Models have a supply requirement of 230V 1
phase, neutral and earth. Maximum cable inlet
size is 10mm².
Program panel is wired to the control base unit
via a RJ45 pre-wired cable.
Networked air curtain interconnects via a RJ45
pre-wired cable
Important notice to installers
Before installation, check the
local distribution conditions,
supply voltage are compatible.
Installation, assembly,
commissioning, service and
maintenance procedures must
be carried out only by suitable
competent qualified persons.
Unauthorised modifications
to the appliance, or departure
from the manufacturer’s guidance
on intended use, or installation
contrary to the manufacturer’s
recommendations may constitute
a hazard.
Note
To ignore the warning and caution
notices, and to ignore the advice from
the manufacturer on installation,
commissioning, servicing, or use, will
jeopardise any applicable warranty, such
a situation could also compromise the safe
and efficient running of the appliance
itself, and thereby constitute a hazard.
Using this manual
Contained within the text of the manual, the
symbols for ‘Caution’ and ‘Warning’ these are
used to highlight certain points.
Caution is used when failure to
follow or implement the
instruction(s) can lead to
premature failure or damage to
the heater or its component
parts.
Warning is used when failure to
heed or implement the
instruction(s) can lead to not only
component damage, but also to a
hazardous situation being
created where there is a risk of
personal injury.
