The installation position on the radiator is directly related to the type of radiator, its heating power
and the heat cost allocator. To guarantee the correct data collection, the heat cost allocators must be
installed and used in a certain position in accordance with requirements.
The radiator’s heat is transmitted directly via the installation back plate to the device’s temperature
sensor or to its remote sensor
• The SonoHCA heat cost allocator is always installed in the centre of the overall length (0.5 x BL)
of the radiator, at a height of ¾ of the overall height (0.75 x BH) measured from the bottom.
• If the height of the radiator is less than (<) 470 mm, the heat cost allocator must be installed at
50% BH.

1. Allocator Installation
Position – Standard
Installation (continuous)
• If the height of the radiator is less than (<) 470 mm, the heat cost allocator must be installed at
50% BH.
General notes:
• The spacing for welding the M3 threaded bolts must be 5 cm. Before welding, the lacquer has
to be removed from the welding points. It must be ensured that the bolts are welded onto a
water-bearing area or a flute.
• Only use M3 bolts with a maximum length of 8 mm or there is a risk that the device will be
damaged.
• Welding to aluminium radiators is not permitted.
• If the radiator has an even number of sections the heat cost allocator should be installed
between the middle sections.
• If the radiator has an uneven number of sections the device should be installed next to the
valve-sided middle section.
• Mount the back plate through the 2 oval holes, adjusted to the top edge of the holes.

2. Wall Mounting
The heat cost allocator has to be wall-mounted if the overall height of the radiator is less than 250 mm
or if, for aesthetical reasons, the heat cost allocator cannot be mounted directly onto the radiator.
In this case, the heat cost allocator is wall-mounted on the side opposite to the valve and at a
minimum distance from the radiator of 10 cm.

10 cm

• After marking and drilling the holes, the aluminium profile is fastened with 2 metal screws and
2 spring washer.
• The parts necessary for the wall-mounting are included in the corresponding fastening-parts
kits for the installation of the remote sensor.
• After installation of the device to the wall and the sensor to the radiator, the sensor cable is laid
in a cable duct.
• Mount the back plate through the 2 oval holes adjusted to the top edge of the 2 oval holes.

• Clean the aluminum back plate with Acetone soaked cotton wool
• Clean the gluing spot on the radiator with Acetone soaked cotton wool.
• Before and after the gluing, trash the first and last 10 cm of glue from the cartridge
• Assemble the heat cost allocator: Aluminum back plate to body and seal it.
• Apply 2 tracks of Pactan glue to the aluminum back plate, left and right of the channel
• Press the heat cost allocator to dedicated spot on the radiator and sway the heat cost allocator
to dispense the glue evenly.
• Press firmly and align. Wait 2-3 minutes check, align and press. Make sure the heat cost allocator
is mounted straight. The heat cost allocator must hold by itself. After 10 hours the heat cost
alloca-tor is firmly glued to radiator.
• Remove redundant glue with a screw driver. Clean the radiator with paper towels.
Removal of glued heat cost allocators
• Remove the aluminum back plate with a screw driver size 2 and a hammer: Position the screw
driver carefully in the middle channel and hammer until the aluminum plate can be removed.
• Remove glue carefully with a carpet cutter and clean glued surface with Acetone.
