Heated or Cooled air is
distributed evenly
How it works
The Thermovec is supplied by hot or cold water from your ASHP. It draws air in from the room in
which it is installed, blows that air over a heat exchanger and exhausts the air into that room. The
temperature of the room is controlled by the Thermovec and the water flow is controlled by a
three-way valve. The air is distributed across the room in a much more efficient manner than a
traditional radiator.
Note: if the Thermovec is used for cooling, the condensate drain must be connected.
Unit characteristics:
Whisper Technology
The use of a cross-flow fan combined with wind-guiding technology make the
Thermovec quiet as a whisper.
Slimline
The Thermovec is only 130mm thick –thinner than traditional radiators of similar
output saving space.
Elegant Design
The rounded and clean outline ensures that the Thermovec will blend into any room.
Easy to use
With a simplified control menu, the Thermovec can be controlled via the touch-
screen panel or the remote control. Note: if you are using a high-temperature
source, the Thermovec should be controlled with the remote control because the
glass whole unit can achieve a temperature of up to 70°C to the touch.
Installation
Installation precautions
To ensures that the installation is performed correctly and safely and to conform to the warranty
conditions the Thermovec must be installed by a suitably qualified technician and in accordance
with this manual.
The electrical aspects of the installation must be carried out in accordance with current regulations.
The Thermovec must be correctly earthed.
The unit must be installed in a position that allows routine maintenance such as cleaning the filter.
Ambient air is drawn in

Positioning the unit
Avoid installing the unit in proximity to other heat sources, in direct sunlight, in damp areas
or where it is likely to come into contact with water. Areas contaminated with combustible
fumes and high frequency radio signals should also be avoided.
Ensure that:
The wall on which the unit is to be installed is strong enough to support the weight.
You are not going to drill through wires, pipes or anything else important when
securing the brackets.
The mounting wall is perfectly flat.
There is nothing to interfere with the airflow around the Thermovec (see below).
If using the Thermovec for cooling, the condensate drain can be routed
satisfactorily.
Minimum Clearances:

Mounting the Thermovec
Using the paper template, trace the position of the bracket holes.
Thermovec Feet.
If you are going to use the Thermovec feet, they must be attached before installation as shown in
the following two diagrams.
First, lay the unit down
carefully to protect both
the Thermovec and the
surface on which it is
placed. Line up both
feet with the four screw
holes for each foot.
Next, using the 8
screws provided
attach the feet
securely, taking care
not to over tighten
the screws.

Fix the two brackets to the wall using suitable fixings: the supplied wall plugs are only suitable for
certain types of walls. Do not tighten until final adjustment to ‘level’ has been made and checked.
4.Installation
Connecting the Pipework.
Flow
Return
The distribution pipework should be hot
flushed and pressure tested before the
Thermovec is connected. The distribution
pipework should be designed to reduce
resistance and automatic air bleed valve
incorporated at key points. The flow and
return should then be connected to the 3-
way valve as shown (Thermovec shown
from the back of the unit)
If the Thermovec is to be used for cooling, a
condensate drain pipe must be fitted to take
resulting condensate away from the unit and
dispose of it safely. The condensate will drip from
aperture A, collect in tray B and the pipe should be
connected at C. If the pipe is to be connected to a
drain, a waterless trap should be used.
