1.1 Introduction
This instruction manual describes the Airbloc ACR
Recessed range of air curtains.
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 or bulkhead
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 50m from the air
curtain. Optional BMS time control, external
thermostats and door interlocks can be installed.
The AC-ACR-PANEL programmer shown above
allows the user to control either a single air
curtain, or a network of up to 6 air curtains with
the same settings, and provides the following
functions:-
- Heat On Off or Auto via optional thermostat
- Off or Low, Medium and High Fan Speeds
For further details please refer to section 10.2
Alternatively on electrically heated models, an
optional SmartElec2 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 low
voltage cable as specified in these instructions.
The SmartElec2 factory fitted base unit
provides terminals for 3 phase supply connection
and the low voltage program panel wires. The
SmartElec2 base unit rapidly pulses energy to the
heating elements. This combined with the inbuilt
intelligent sensor control, maintains a fixed outlet
temperature, thereby reducing energy
consumption as compared to an air curtain without
the SmartElec2 control.
The SmartElec2 program panel shown above
allows the user to control either a single air
curtain, or a network of up to 16 air curtains, each
with different settings if required, and provides the
following functions:-
• Heat On or Off
• Off or Low, Medium and High Fan Speeds
• Air Outlet Temperature
For further details please refer to section 10.4
1.2 General
All installations must be in accordance with the
regulations in force in the country of use.
These instructions must be handed to the user on
completion of the installation.
Installers and service engineers must be able to
demonstrate competence and be suitably qualified
in accordance with the regulations in force in the
country of use.
To ensure continued and safe operation it is
recommended that the appliance is serviced
annually.
The manufacturer, offers a maintenance service.
Details are available on request.
The air curtain outlet grille and case air inlet slots
must not be obstructed during use.
1.3 Electrical Supply.
For full electrical loadings, please refer to the
individual technical data sheets within this manual.
It is recommended that the electrical supply to the
base unit in the air curtain is via an appropriate
switched isolator 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.

BMS control, time switches, room thermostats and
door interlocks can be installed at the discretion
and responsibility of the installer.
All units must be wired in accordance with I.E.E
regulations for the Electrical Equipment of
Buildings and the installer should ensure that a
suitable isolating switch is connected in the mains
supply.
Warning
For safety reasons a good earth connection must
ALWAYS be made to the heater and control box.
1.3.1 Electronic controller
Electrically heated supply is either 230V 1 phase
(6 and 9kW options) or 415V 3 phase (9 to 24kW),
Neutral and Earth. Max cable inlet size is 4mm².
Ambient and LPHW supply is 230V 1 phase,
Neutral and Earth. Max cable inlet size is 4mm².
Remote unit is wired to the base unit via a Belden
9174 cable (or direct equiv).
1.3.2 SmartElec2 controller
Electrically heated supply is 415V 3 phase, neutral
and earth. Max cable inlet size is 10mm².
Remote unit is wired to the base unit via pre-wired
4core cable.
Networked air curtain interconnects via pre-wired
4 core cable.
1.4 Location.
Airbloc 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, within the ceiling void or roof space.
Care must be taken to allow complete free air
movement into the inlet grilles 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.
Units can be mounted adjacent to each other to
cover the full door opening across wider
entrances.
1.5 Clearance distances
It is recommended that a minimum clearance of
100mm is allowed around the case sizes detailed
below. The clearance allows for cable entry and
prevents combustible surfaces overheating.
The minimum mounting height (floor to grille) is
1.8m. The recommended mounting height is 3m
for standard and 4m for high capacity models.
1.6 Health and Safety
Sole liability rests with the installer to ensure that
all site safety procedures are adhered to during
installation.
Sole liability rests with the installer to ensure that
protective safety wear such as hand, eye, ear and
head protection is used during installation of the
product.
Do not rest anything especially ladders against the
product.
1.7 Standards
Units conform to the European electrical standard
BS EN 60335-2-30 and to the following European
CE directives-
2006/95/EC - low voltage;
2004/108/EC - electromagnetic compatibility.

4.1 Installer Wiring - Electrically Heated 6 & 9kW SINGLE PHASE ONLY
The program panel is connected to the base unit via a set of 3 way connectors marked "+12V”, “DATA”
and “GND". Interconnecting wiring is via Belden 8132 or equivalent cable as shown. Max length 50m.
It is recommended that this control cable is run separately
within its own trunking to avoid external interference.
Door switch to be volt free and wired normally closed contacts
to terminals D1, D2. (Contacts
broken when door is open).
External switch (ie BMS enable) to
be volt free and wired via normally
open contacts to terminals B1, B2.
Optional internal/external sensor
to be wired to terminals S1, S2.
Protection
External circuit breaker with the appropriate
rating should be installed for the protection
of the installation.
