Installation.
The Jet is designed for surface mounting
horizontally above a door opening at a height
of 1.8m minimum to 2.3m maximum (from
oor level to the underside of the appliance).
Multiple Jets mounted side by side may be
used for wider doorways. The unit must
be mounted internally within a building and
can be either wall or ceiling mounted.
Before tting, obtain suitable screws and wall
plugs, taking into account wall or ceiling type
and unit weight. The heater must not be located
immediately below a socket outlet. Do not cover
or obstruct the air inlet or outlet grilles as this
can cause overheating and may cause a risk
of re. Do not install heater in environments
containing ammable or explosive material.
Using the mounting bracket as a template
determine optimum location for the heater,
ensuring the product is placed in freely circulating
air, place bracket on the wall or ceiling and
mark position of the two xing holes. Drill
wall or ceiling accordingly and securely x
mounting bracket into position. The panels
are coated in an easy to peel protective lm.
Please ensure all the protective lm is removed
before the air curtain is put into service.
Align and position mounting bracket
into the two slots on the rear plate
of the heater (refer to Figure 2).
Ensure the serrated washer, at each end of the
heater, is positioned between the mounting
bracket and the internal hanging bracket (see
Figure 3). Tilt and point heater into the preferred
direction and rmly tighten both xing screws.
Using a Pozi No. 2 screwdriver the xing screws
are tightened via an access hole in each end cap.
What’s in the box?.
• Thermoscreens Jet heater unit
• Mounting bracket
• Cable gland (supplied loose)
• Remote control
• Batteries
For warranty purposes
please retain your receipt
as proof of purchase.
All electrical wiring and connections must
be carried out by a competent qualied
electrician in accordance with the latest
edition of the IET wiring regulations and/
or local statutory regulations.
Ensure that the supply cables, circuit breakers
and other electrical installation equipment are
correctly sized for the heater being installed.
For each heater a single phase local isolator
with a contact separation on both poles of
at least 3mm must be tted to the supply
wiring (the isolator must be tted within an
accessible position and labelled accordingly).
The heater should be connected to a 230V
AC 50Hz electrical supply and must be
earthed. Use 3-core round exible mains
cable type 3183Y for the nal connection
to the heater from the local isolator.
Remove two M4 x 12mm pan head Pozi
screws at top of the heater and release
the power connector plate. Fit cable gland
to power connector plate. Insert electrical
supply cable via cable gland (see Figure 4)
and tighten gland around cable.
Connect each of the cables as follows:-
• Live brown cable to terminal marked L
• Neutral blue cable to terminal marked N
• Earth green/yellow cable to terminal marked
Position the electrical supply cables as they
come out of the terminal block as shown in
Figure 4. Ensure only sufcient cable is pulled
through to enable connection to terminal
block and to avoid excess cable coming
into contact with any moving parts. Carefully
insert all cables through the rectangular hole
in the top of the heater and ret the power
connector plate. Ensure mains supply cable is
correctly secured by the plastic cable gland.

Product Operation.
Warning: The product should not
be left to operate unattended.
Control of the heater can be achieved
by using the two integral switches
mounted adjacent to the discharge grille.
Press button (1) to switch the product
on in full heat (3kW) mode. The left
most indicator will light red to show the
product is in full heat. Press button (2)
and the product will switch down to half
heat (1.5kW) mode and the light will turn
pink. A second press of the button will
disable heating and to just have the fan
running - the light will turn blue. Pressing
the button again will switch the unit off.
Before leaving site it is important that
the over door heater installation and
these instructions are “Handed-Over” to
the end user or their representative and
the operation of it is fully explained and
that they understand how it operates.
Warning: This appliance is not intended
for use by persons (including children)
with reduced physical, sensory or
mental capabilities, or lack of experience
and knowledge, unless they have
been given supervision or instruction
concerning use of the appliance by a
person responsible for their safety.
Children should be supervised to ensure
that they do not play with the appliance.
Remote Control Operation.
Product Features Explained
Warning: The use of the thermostatic, timer
and adaptive start functions mean the product
will start and stop automatically. It is the
responsibility of the operator to ensure that
the product’s air inlet and outlet grilles are kept
clear and unobstructed and the product is in
a sufciently large space to avoid overheating.
The product should not be left to
operate unattended.
• Thermostat Controlled
The product will heat up to the
temperature shown on the remote
control screen. When the entering air
reaches this temperature the product
will switch off. As the sensor is inside
the product, it can give an articially
high reading after the product has
been heating. To reduce this as much
as possible, the unit has a built in fan
overrun to expel excess heat when
the set point has been reached. The
thermostat is for crude control only and
should not be used for precise control
of room temperatures.
• Timer Controlled
This allows the unit to be programmed
to switch on or off at certain times.
The procedure for this is shown below.
• Adaptive Start
When in timer controlled mode, the
heating will come on earlier than set
when the air temperature is colder.
When it’s warm (but still below the
target temperature) then the product
will come on later.
Setting the time
Switch the product on with the remote.
Press and hold the “A” button for 6
seconds until the hour ashes. Use the
up and down buttons to set the value for
the current time. Press the “C” button
to advance to minutes and repeat the
procedure. Press the “C” button again to
set the day of the week (eg. Monday = 1).
Press the “C” with the remote pointed at
the unit to save the settings and exit.
Setting up the timer
Switch the product on with the remote.
Hold the “G” button for 6 seconds to enter
programming mode. The LCD screen
ashes ‘1’ to indicate Monday. Use the
up and down arrows “B” to adjust the
temperature and once set press the ‘C’
button to set the hour(s) on the product.
The single and double blocks indicate the
product will heat as needed, no blocks
indicate will the product is not heating.
Press the ‘G’ button again to set the same
functionality for the remaining days. Repeat
as necessary until all days have been
programmed. The timer functionality can
be engaged or disengaged at any time by
pressing the ‘H’ button on the remote.

Thermal Safety Cut-Outs.
If the heater exceeds normal operating
temperature the thermal safety cut-outs will
operate and isolate electrical supply to the
heating elements. Users must isolate the product
in the case of over heating, before determining
and resolving the cause of the fault. Allow heater
sufcient time to cool before restoring supply.
If the fault persists arrange for a competent
engineer to attend site and investigate.
In order to avoid a hazard, this appliance
must not be supplied through an external
switching device, such as a timer, or
connected to a circuit that is regularly
switched on and off by the utility company.
Service and Maintenance.
Always disconnect and isolate the mains
electricity supply before installing, maintaining
or repairing this equipment. All maintenance/
repairs should only be carried out by a
competent electrician or Thermoscreens
appointed technician. To ensure the heater
operates efciently the air inlet and outlet
grilles, fan impellers, housings and motors
must be kept free of dust and debris. Regularly
vacuum and clean any build-up of dirt and
debris within the heater (please note that the
motor is permanently lubricated and requires
no additional lubrication). Once the heater has
been cleaned check all electrical connections
within the unit, ensuring terminals are tight and
that crimped connections have not become
loose. If the outer casing requires cleaning this
should be carefully done using a soft cloth.
Do not use solvents or abrasive materials.
Reconnect the electrical supply and fully function
test the heater to ensure correct operation.
