Introduction
This instruction manual describes the Airbloc AC-
Mini range of air curtains. Models range from
600mm in length rated at 3kW, 800mm rated at
4.5kW and 1000mm rated at 6kW. They are de-
signed for mounting above doorways and similar
entrances, and may be used as space heaters.
The AC600SE3 air curtain is supplied with rocker
switches attached to the underside of the front
face (see photo above). These switches give am-
bient airflow, 1kW, 2kW and 3kW heater control.
Both the AC800SE4.5 AND AC1000SE6 air cur-
tains are supplied with remote control boxes which
houses 3 rocker switches. These switches give
ambient airflow, 1, 2 and 3kW heater control.
For further details please refer to section 6 - User
instructions in this manual.
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 rec-
ommended that the appliance is serviced annu-
ally.
The manufacturer, offers a maintenance service.
Details are available on request.
Electrical
This unit is suitable for connection to 230/240V
50Hz supplies.
The AC600SE3 has a full heating load of 3kW.
The AC800SE4-5 has a full heating load of 4.5kW.
The AC1000SE6 has a full heating load of 6kW.
The connection to be made between the heater
and the remote control box (AC800 and AC1000
only) are shown in figures 2 and 3. An earth termi-
nal is adjacent to the terminal block and is clearly
marked with the symbol.
Warning
For safety reasons a good earth connection
must ALWAYS be made to the heater and con-
trol box.
The unit must be wired in accordance with I.E.E
regulations for the Electrical Equipment of Build-
ings and the installer should ensure that a suitable
isolating switch is connected in the mains supply.
Location
Airbloc units should be installed horizontally di-
rectly over the door opening. It is recommended
that the air curtain is installed on the inside of the
building, within the open room space against a
wall or ceiling. Care must be taken to allow com-
plete 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.
When mounted over a standard shop doorway the
unit should be fitted as low as possible and not
more than 2.5 meters or from ground level.
A single unit AC600SE3 will provide reasonable
coverage for an internal doorway, a single
AC800SE4-5 unit will provide coverage for an in-
valid doorway width up to 800mm, and an
AC1000SE6 unit is suitable for door widths up to
1m wide. Units can be interlinked across wider
entrances.
The unit shall be mounted so that the airflow is not
obstructed by any part of the doorframe. With a

minimum clearance distance to ceiling of 300mm.
These 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.

Mounting
Airbloc units should be installed horizontally di-
rectly over the door opening. It is recommended
that the air curtain is installed on the inside of the
building, within the open room space against a
wall or ceiling.
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.
When mounted over a standard shop doorway the
unit should be fitted as low as possible and not
more than 2.5 meters or from ground level.
A single unit AC600SE3 will provide reasonable
coverage for an internal doorway, a single
AC800SE4-5 unit will provide coverage for an in-
valid doorway width up to 800mm, and an
AC1000SE6 unit is suitable for door widths up to
1m wide. Units can be interlinked across wider
entrances.
The unit shall be mounted so that the airflow is not
obstructed by any part of the doorframe. With a
minimum clearance distance to ceiling of 300mm.
These 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.
Installation
Carefully unpack the unit. The heater may be
mounted in three alternative ways:
6. Installation Details.
• Direct to a suitable wall or bearer with appro-
priate fixings either using the holes in the
swivel mounting bracket or the key hole slots
in the back plate of the product. See Figure 1
for mounting centres.
• Suspended by 10mm drop rods through the
holes provided in the top of the swivel mount-
ing bracket.
• For use as an air curtain the air outlet should
be directed down to the floor. For use as a
heater the air outlet should point into the
room.
Note The air outlet is opposite the face where cable
entry holes are provided.
Electrical Connections
These units are suitable for connection to a
230/240 Volt 50 Hz single phase ac supply. The
heaters consume 3.0kW, 4.5kW & 6kW respec-
tively at 240 Volts when switched to the full heat
position.
The appliance shall be connected to the supply via
a circuit, in which there is an all-pole switch. Test
for correct operation and refit the cover.
For connection to the mains supply it will be neces-
sary to remove the outer cover from the unit. After
removing the cover you will note the mains terminal
block and it will be necessary to connect the mains
supply and the lead from the remote switch box
prior to refitting the cover. Wire in accordance to
Figures 2, 3 and 4. (or fig.6 where appliciable)
For safety reasons, a sound earth connection must
always be made to the unit before it is put to use.
The unit should be wired in accordance with IEE
Regulations for the Electrical Equipment of Build-
ings.

AC600SE3 Operation
The AC600SE3 air curtain is supplied with rocker
switches attached to the underside of the front
face.
The right hand switch marked with 4 dots switches
the blower on to give ambient airflow.
With the right hand switch in the ON position the
heat controls can be selected.
When the centre switch (marked with a single
black line) is depressed the heat output is 1kW.
When the left hand switch (marked with two black
lines) is depressed the heat output is 2kW.
When both switches are depressed the heat out-
put is 3kW.
Both the AC800SE4.5 AND AC1000SE6 air cur-
tains are supplied with remote control boxes which
houses 3 rocker switches.
The remote control box houses 2 switches, a dou-
ble pole and a single pole, and gives the following
functions:
• Switch 1 Off/Fan only to provide circulation
of room air.
• Switch 2 Half Heat
• Switch 3 Full Heat.
Protection
The unit is protected in the event of fan failure, or
an obstruction of the free air flow, by a thermal
PTC Self Hold Cut Out.
Having tripped the PTC Cut Out remains open,
effectively switching off the heating elements, as
long as mains power is available inside the appli-
ance.
The PTC Cut Out will only reset when the appli-
ance is
switched OFF and allowed to cool for at least 20
minutes.
To reset the PTC Self Hold Cut Out
a) The cut-out is reset by switching OFF mains
power to the appliance.
b) Allow the appliance to cool for 20 minutes.
c) Restart, switch on the appliance. If the cut-
out trips again a qualified electrician should
be consulted.

grilles. For this reason regular cleaning is neces-
sary, paying particular attention to the removal of
dirt build up on the rotor blades.
Cleaning of the fan is best carried out with a soft
brush.
A single drop of light oil should be applied to the
motor bearing from time to time.
