1.2 Certicates of conformity
Certicates are available from the Quality Control Department
at Nortek Global HVAC (UK) Ltd.
1.3 General product information
Models range from 1000mm to 2000mm in length, in both
Standard and High capacity and are available in either
Electrically heated, Ambient or LPHW. They are designed for
discreet positioning in a suspended ceiling or bulkhead in the
doorways of retail or commercial premises. Optional case for
doorways with restricted space and no suspended ceiling/
bulkhead are available.
Each air curtain is supplied with a fully electronic controller
giving multi fan and heat settings (electrically operated units)
via a simple key pad which can be mounted up to 100m from
the air curtain.
Optional BMS time control, external, thermostats and door
interlocks can be installed.
The programmer shown above allows the user to control
either a single air curtain, or a network of up to 16 air curtains
with the same settings, and provides the following functions:-
• Heat On O or Auto via optional thermostat
• O or Low, Medium and High Fan Speeds
For further details please refer to section 10.1
Alternatively on electrically heated models, the optional
SmartElec3 control system consists of a base unit (installed
within the air curtain) and a program panel that can be
installed remote from the air curtain.
Usually, the program panel is mounted at a low level from
the air curtain for user access and to a maximum distance of
100m.
The base unit and program panel are linked by a pre-wired
low voltage cable as specied in these instructions.
The SmartElec3 factory tted base unit provides terminals
for 3 phase supply connection and sockets the low voltage
program panel cable. The SmartElec3 base unit rapidly pulses
energy to the heating elements. This combined with the in-
built intelligent sensor control, maintains a xed outlet
temperature, thereby reducing energy consumption as
compared to an air curtain without the SmartElec3 control.
The programmer shown above is the same as used on
standard air curtains and allows the user to control either a
single air curtain, or a network of up to 16 air curtains, each
with dierent settings if required, and provides the following
functions:-
• Heat On or O
• O or Low, Medium and High Fan Speeds
• Air Outlet Temperature.
For further details please refer to section 10.2
Note
Neither asbestos nor soft soldered joints are used in the
construction or manufacture of the Airbloc ACR Recessed Air
Curtain range. The materials selected for use can withstand
the mechanical, chemical, and thermal stresses which they will
be subject to during foreseen normal use when installed in
accordance with the manufacturers recommendations.

4.1 Installer Wiring - Electrically Heated 6 & 9kW SINGLE PHASE ONLY
The program panel is connected to the base unit via a pre-wired RJ45 cable max length 100m.
It is recommended that this cable is run separately within its own
trunking to avoid external interference.
External switch inputs (eg Timer) to be volt free and wired via normally open contacts to terminal pair marked eg. ‘timer’
(contacts closed to enable). Remove relevant factory tted jumper for any optional input.
4. Wiring Diagrams.
