BMS control, time switches, room thermostats and
door interlocks can be installed at the discretion
and responsibility of the installer.
All unit 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 415V 3 phase, neutral
and earth. Max cable inlet size is 6mm².
Ambient and LPHW supply is 230V 1 phase,
neutral and earth. Max cable inlet size is 6mm².
Remote unit is wired to the base unit via a 3 core
low volt cable. Networked air curtain interconnects
via a 3 core low volt cable.
1.3.2 SmartElec controller
Electrically heated supply is 415V 3 phase, neutral
and earth. Max cable inlet size is 4mm².
Remote unit is wired to the base unit via 2 pairs
24V Belden 8132 cable (or direct equiv).
Networked air curtain interconnects via 2 pairs
24V Belden 8132 cable (or direct equiv).
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. Due to the in-built safety function of the
motor, a switching slave panel must be used if
using a singular switchbox.
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

BS EN 60335-2-30:1997 and to the following Eu-
ropean CE directives. 73/23/EEC low voltage;
