The maximum mounting height is m.
1. General Information
1.1 Introduction
The heaters are designed for discreet positioning in
a suspended ceiling or bulkhead in the doorways of
retail or commercial premises. Overall energy sav-
ing is likely when the heater is sited above a fre-
quently opened external door as the airstream can
prevent heat loss. Will fit a recess as shallow as
195mm.
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

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 cover the entire door
width.

3.4 Installation
It is the sole responsibility of the installer to ensure
that the points of attachment to the building are
sound. Consultation with the consultant/architect or
owner of the building is recommended to ensure
that a sound, mechanically stable installation is
achieved.
Before fitting or wiring the air curtain, ensure the
outlet is facing the doorway as on the picture and
see the general installation guidance notes.
Using a pozidrive screwdriver slacken the two M5
screws in the corners near air inlet side and remove
the two M5 screws in opposite corner near the out-
let. Slide the lid sideways until the keyhole slots
pass over the screw heads. The grille assembly can
now be removed from the case.
Each unit has 2 fixing brackets from which it is sus-
pended. The brackets may be removed to assist in
passing the air curtain through the recess then reat-
tached when in-situ.
Either drop rods or catenary wire can be used to
fasten the air curtain to the ceiling support structure.
The height between the ceiling face and the top of
the air curtain case needs to be adjusted to circa
140mm to enable the grille assembly to fit flush with
the ceiling. Adjust accordingly.
After fitting the product in the ceiling recess and ad-
justing the height to ensure that the grille sits flush
to the ceiling (when re-fitted) take the grille assem-
bly and refit using the screws removed.
4. Electrical Connections

4.1 Electrical connections Fig.7 Grille Earth lead
With grille removed, connect the electrical supply
and controls wiring to the appropriate terminals (see
relevant wiring diagram section).
The unit has four holes for the cable entry, two on
the top and two on the side. Cable entry may be
moved to alternative position if desired (see Fig.8
drawing).
An EARTH lead is connected to the lid from the unit
body, push on connection at grille. When replacing
the grille onto the unit ensure the EARTH lead is re-
connected. (see Fig.7 )

ALWAYS ENSURE THAT THE MAIN EXTER-
NAL ELECTRICITY SUPPLY IS SWITCHED
OFF EFORE COMMENCING ANY MAINTE-
NANCE ON THIS HEATER.
To obtain the best results from the heater, it is es-
sential to avoid the accumulation of dust and dirt
within the unit on the air inlet and discharge grilles.
For this reason regular cleaning is necessary, pay-
ing 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.
The product should be serviced annually.
Servicing shall be undertaken by a competent per-
son.
6.2 General
If the air curtain does not operate after switching on,
then a suitably competent service engineer should
be called to identify the nature of the fault.
All Air Curtains are fitted thermal cut-outs and motor
thermal protection.
Other faults in relation to the element, motor and
wiring should be identified using conventional fault
finding techniques.
In the event that electrical components are replaced,
please ensure that electrical safety checks in accor-
dance with the regulations in force in the country of
use are undertaken.
6.3 Thermal and fault protection
The units are protected from overheating in the
event of fan failure or an obstruction of the free air-
flow by thermal cut-outs.
6. Servicing & Maintenance
6.1 Maintenance
If this happens, the thermal cut-outs effectively
switch off the appliance by disconnecting power to
the control circuit. The appliance will not operate
until the thermal cut-outs are manually reset. This
should be done by a competent electrician.
The heaters are also protected by thermal fuses to
prevent catastrophic failure. The thermal fuse will
trip and disconnect power to the affected heater.
Thermal fuses are not resettable.
6.4 Fault Conditions
If the heater will not operate, disconnect it from the
mains and arrange for a certified electrician to at-
tend to investigate the reason.
6.5 Replacing Fan Heater Assembly
Remove the lid.
Disconnect the internal wiring from the main termi-
nal block. Remove the four nuts and washers fixing
the fan heater assembly to the back of the case.
The fan heater assembly can now be eased for-
ward and removed from the heater case. Fit re-
placement fan heater and reassemble in reverse
order.
6.6 Spares
It is essential when ordering spares or replacement
parts to state the model number and the serial
number on the rating place fixed to the top of the
unit.
