INSTRUCTION MANUAL
CEILING FILM – ECOFILM C
Workshop-made heating films
1. Installation conditions
• Heating films are designed for dry building process applications; they don't need to be glued but they have to be
fixed to prevent movement/sliding beyond the non-heating edges. They mustn't be installed during temperatures
which are lower than 3 °C and they mustn't be exposed to temperatures of over 80 °C on a long-term basis. The
minimum radius of a bend in the heating film is 35 mm. It mustn't be installed on uneven surfaces. The heating
element mustn't be crumpled. The heating film must be in close contact with other parts of the building construction
and must be fully covered by the ceiling.
• The non-heating edge of the film is a longitudinal transparent part, mostly with printed text and information about
the product, parallel to the copper conductor bus bar. This edge can be made narrower by cutting it to a distance
of 11 mm from the copper conductor bus bar, or perforated/pierced with a nail at a distance of 11 mm from the bus
bar. Heating films must not be arranged in layers, overlap or be touched by other parts than by the non-heating
edges. The non-heating edges may overlap. The film doesn't have a distinguishable top and bottom surface. The
heating film, including the connections and supply conductors, must be protected from damage during installation.
• The supply circuits must always be equipped with a residual current circuit breaker with a rated residual actuating
current of < or = 30 mA. The execution of the installation (disconnection, protection or regulation) must enable
electrical disconnection of the film in all poles (this condition is met also by some thermostats which Fenix offers).
The films are designed for a 230 V supply; when connected in series the value of current which is passing through
the copper conducting film mustn't exceed 10 A.
• The heating films mustn't be installed in walls and ceilings lower than 2.3 m and inclined less than 45° from the
vertical level. On a long-term basis, the heating films mustn't be covered by ceiling plasterboard or other objects of
which the thermal resistance (R) is higher than 0.08 m
2
K/W.
• The heated areas must be separated from the walls and other dilatation units by a dilatation joint. The heating film
must not pass through the dilatation joints; the supply cable which is passing through these joints must be laid in
a way that enables free movement of the separate units in such a way that this cable doesn't get damaged.
• Usage of the heating film or placement of the heating film which differs from that which is mentioned in these
instructions can be harmful to life and health or may cause material damage. The warranty conditions do not apply
to such use. The supplier must notify other suppliers, the owner and, if possible, also the user that no penetrative
fixtures, e.g. nails, screws and drills, must be used on the area where heating films are installed. The heating film is
produced according to the requirements of ČSN EN 60335-2-96 and must be installed according to the valid ČSN
norms (the laying of a heating film is included in the ČSN 33 2000-7-753).
• We do not recommend the installation of ECOFILM heating film with a wattage higher than 200 W/m
2
into the
structure of the plasterboard construction. In rooms where people reside permanently, and where the ceiling height
is lower than 2.40 m, the installation of ECOFILM heating film with a wattage higher than 150 W/m
2
is not
recommended.
