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 reg-
ulations 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 415V 3 phase,
Neutral and Earth. Max cable inlet size is 4mm² or
6mm² (refer to individual technical specification).
Remote unit is wired to the base unit via a
screened twisted pair 28AWG (or direct equiva-
lent).
1.4 Location
All 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 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.
Units can be mounted adjacent to each other to
cover the full door opening across wider
entrances.
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.
1.5 Clearance Distance
It is recommended that a minimum clearance of
300mm is allowed around the top and front of the
unit. The clearance allows for cable entry and
prevents combustible surfaces overheating.
The minimum mounting height (floor to grille
outlet) is 1.8m. The recommended maximum
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-
73/23/EEC - amended 98/68/EEC low voltage;
89/336/EEC electromagnetic compatibility.
WARNING:
THIS AIR CURTAIN SHOULD NOT BE
INSTALLED WHERE THERE IS A
CORROSIVE ATMOSPHERE.
