Heated or Cooled air is

distributed evenly

How it works

Ambient air is drawn in

Return

Flow

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 touch­screen 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.

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:

Installation

Side opening

Lift the screw cap (A) and undo the screw (B) beneath it. Move the side panel (c) slightly and lift it
out.

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.

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.

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 3­way 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.

certain types of walls. Do not tighten until final adjustment to ‘level’ has been made and checked.

Bleeding the Thermovec

Power on/off. Also used to cancel an action or to return to the previous menu

Air Vent or Time. Used to display time settings, set the timer and to turn the air vent on
or off.

Fan Speed. Used to set the fan speed.

Up. Used to increase a value or to go up a menu level.

Down. Used to decrease a value or to go down a menu level.

The Thermovec must be bled before power is
applied i.e. before it is switched on. Use a
screwdriver to open the bleed valve on the
side of the Thermovec until all air is expelled
from the unit then close the valve again taking
care not to over-tighten it. It is
recommended that each Thermovec be bled
again one it has been running for a few hours.
If the unit is powered-up before it is bled, the
3-way valve will have closed and it must be
opened manually.

Cleaning and Maintenance.

Filter replacement order

When removing the filters, treat the catches
gently as they do not require much pressure and
the lugs can be broken. To replace, locate
carefully in the square apertures.

There is very little to be done to maintain the Thermovec. Please turn the unit off before cleaning it
and use a clean, damp cloth but no abrasives or solvents as these could damage the finish. The
three filters underneath the unit should be cleaned periodically by removing them, rinsing them
under clean running water, drying and replacing them:

Any repairs should be undertaken by qualified technicians using genuine spare parts supplied by
Earth Save Products Ltd. Should a leak develop, the unit should be switched off and advice sought
from your installer or the ESP Ltd Technical Department.

Correct Disposal of this product

This product should not be disposed of with other household waste but recycled in accordance with
current Government policy.
