A DRAFT OR A PICTURE OF THE HEATING TABLE, SUPPLY TABLE AND ACCESSORIES
DESCRIPTION
GPRU type heating cables are used to protect against freezing. They are laid on the outer surface of
pipes and valves, the same, the emitted heat allows to protect the inner liquid against freezing. The
cable is equipped with a temperature regulator which automatically switches on the heating circuit at
+3°C (*+5°C) and switches off at a temperature of +11°C (*+13°C). The device measures the tem-
perature on the pipe’s surface. In order to give a proper temperature measurement and an appropriate
response of the heating cable, it is very important to mount properly the temperature regulator on a
pipe. The measuring surface of a temperature regulator should be maximally equal with the protected
surface of a pipe. Too little contact of both surfaces can cause a heat damage to the heating cable. The
way of applying a temperature regulator to the surface of a pipe is shown in the drawing.

The heating cable should be mounted on the pipe by means of cable ties or mounting tapes. In addi-
tion, it is recommended to apply insulations, e.g. heat insulations. Insulation should be made of fl ame
retardant or noncombustible material.
The GPRU heating cables are designed for outdoor and indoor use. They are made for 230 V nominal
voltage 230 V and 18 W/m (*15 W/m).
The temperature regulator is placed on the connection of heating and power cables, acting as a me-
chanical connection of the heating and power part of a device.
The supply cable is ended with a plug that is inserted into a 230 V AC socket.
Heating cable GPRU - the set included:
● one-sided 18 W/m (*15 W/m) power supply heating cable connected by means of a temperature
regulator with w supply cable ended with a plug,
● installation instruction with the Warranty Card.

REMARKS
• During installation it is required to follow in-
structions included in the Heating Cable Man-
ual Instruction
• It is forbidden to mount the cable on pins,
bolts, screws or other fi xing elements that can
damage the outer coating of cables.
• The installation of a temperature regulator,
which is a part of a complete hating cable,
should be carried out with a particular attention
so that the measuring surface of a tempera-
ture regulator is closely attached to the pipe.
• The cable installation base must be smooth
with no sharp edges or sharp fi xing elements
• Heating unit cannot be mounted on non-uni-
form bases.
• The heating cable should not be installed in
places with permanent building.
• The heating cable, the supply cable and the
plug resistance must be measured at least
twice: after opening the packaging and before
starting the installation works and after arrang-
ing the heating cable in its fi nal place.
• It is not advisable to install the heating mats if
the ambient temperature is below + 5°C.
• Don’t cut the heating cable or its connection
with power supply cable and the plug.
• The heating cable should not undergo exces-
sive strain and should be protected against
sharp device damage.
• It is required to make a draft or add pictures of
the arrangement of the heating cable, power
supply cable and the connection place of the
heating cable with power cable (“cold wire”).
The draft or pictures are an integral part of the
as-built documentation.
• Heating unit must be supplied by means of a
device from TN-S electric circuit with RCD (re-
sidual current device) of nominal power supply
lower than 30 mA. The installation should have
surge protection.
• The heating cables must not come into con-
tact, cross with each other or other cables
- this could damage the insulation. The mini-
mum distance between the heating cables
must not be less than 5 times its diameter.
• The heating cable must be evenly wrapped on
the protected surface.
• The non-detachable supply cable cannot be
replaced. If the cord is damaged, the equip-
ment is useless.
• The device is not intended to be used by peo-
ple (children) with limited physical, feeling or
psychic ability or people without experience
or without the device knowledge unless it is
under supervision of a person responsible for
safety or according to installation manual.
• Pay attention to children - they must not play
with the device.
• Do not instal on pipes with the temperature
higher than niż 80°C.
• The radius of heating cable bending shall not
be less than 8 times of its diameter.
• The heating cable cannot be immersed in any
liquid.
• The GPRU heating cable is not designed to
be used on roofs, in gutters, in drain pipes, on
pavements, stairs and driveways.
