WARNING:
n Before use read this manual carefully.
n Warning label must not be removed.
n Heating panels must only be used by
qualified personnel.
n Installation and maintenance must be
carried out by qualified personnel.
n Heating panels must be installed
maintaining good contact to surface
that is to be heated.
:
n Do not use in explosive or
hazardous areas.
n Do not touch when heating
panel is energised.
n Do not exceed maximum operating
temperatures.
n Do not overlap heating panels.
n Do not use if heating panel
is damaged.
n Ensure the use of adequate
thermal control.
GENERAL:
Heating panels of the H/SR series are
silicone insulated heating devices for
industrial use.
Dependant on the requirement, they can
be designed with:n adhesive backing.
n Temperature sensors and controllers.
n Various fixing methods.
n A range of operating voltages and
ratings.
n UL or VDE approval.
:
They are used for heating up and
compensation of heat losses on a variety
of applications.
The maximum temperature of use is
200°C (180°C with adhesive backing). The
maximum achievable temperature,
however, depends on the specific operating
conditions. It may be influenced by the
heat conductivity of the materials and
media to be heated as well as the
throughput, the ambient temperature, the
insulating material and the insulation
thickness.
SAFETY INSTRUCTIONS:
MALFUNCTION:
The heating panels are intended for use in
industrial electric heating apparatus.
Heating panels or their cables that
show visible signs of damage or are
not operating correctly should be
disconnected from the electrical
supply and removed from the
installation immediately.
They correspond to the
BS EN 60335-1:2002.
The heating panel has to be operated
in accordance with these standards
and regulations.
The heating panel should be installed
on an electrical system protected by a
residual-current circuit breaker.
COMMISSIONING AND OPERATION:
n The maximum temperature for using
the heating panels is 200°C (180°C
with adhesive backing).
n Do not allow the heating panels to
exceed this temperature.
n Suitable temperature control
must be used.
n Please observe the requirements of
the standards listed under ‘Safety
Instructions’.
n Correct function of temperature control
and limiting devices must
be checked on first operation.
MAINTENANCE AND CARE:
TECHNICAL DATA:
Maintenance and care is performed
according to the standards listed under
‘Safety Instructions’.
For nominal voltage, mains frequency and
nominal performance please refer
to specification:-
The function of the temperature
controlling and limiting safety device must
be checked and the surface and
connection cable should be inspected for
visible damage at least once a year. The
surface of the heater should be cleaned
with a damp cloth. Do not use solvents.

INSTALLATION AND CONNECTION:
The heating panels are fitted to the
component to be heated and fixed using
springs, hooks, quick release fasteners,
adhesive backing, silicone glues or
separate straps.
When fitting with adhesive backing or
silicone glue all surfaces must be clean
and de-greased. Ensure there are no
sharp edges that may damage the silicone
insulation.
The heating panels are moisture resistant
and are not suited for immersion.
Metallic components coming in contact
with the heating panel have to be
incorporated in the protection measures of
Protection Class I (protective earthing).
A residual current device circuit breaker
is recommended.
INSTALLATION OF NON-ADHESIVE HEATER MAT:
1 Ensure surface to be heated is clean of
grease and dirt (use cleaning solvent if
required).
5 Place H/SR element into position,
against surface to be heated and press
firmly ensuring good, even contact.
2 Whilst the elements are flexible, care
should be taken not to roughly handle,
fold or crease them.
6 Route and secure heater mat cold
lead/cable
3 Ensure H/SR heating element is clean
of dust and dirt. (to clean use a damp
cloth).
8 Electrically static test heater mat for
correct element resistance reading and
earth isolation.
4 Apply a thin layer of suitable silicone
rubber adhesive to the side of the
element which is to be placed in
contact with the surface to be heated.
9 Equipment that the heater mat is fitted
to should provide protection against
electrical shock according to relevant
European standards.
7 Visually inspect heater mat installation.
