A DRAFT OR A PICTURE OF THE HEATING CABLE, SUPPLY TABLE AND ACCESSORIES

DESCRIPTION

Heating cables type GPRN are used to protect gutters and drain pipes against de-icing. They are 

resistant to UV radiation and are laid in gutters in pairs or individually. They are fixed by additional 

accessories (clips for gutters, clips for drain pipes, suspensions and chains). The cables must be 

mounted with a temperature controller, equipped with a temperature sensor or ice and snow sensors. 

The arrangement and application of particu-

lar accessories are shown below.

• The GPRN heating cables are designed 

to operate outdoor. They are prepared to 

operate  at 230 V AC nominal voltage and 

18 W/m power.

• The heating cable is connected with po-

wer supply cable, which by means of a 

temperature controller is connected to 

230 V AC.

• The device should be connected accor-

ding to the details included in this ope-

rating manual. Installation, connection 

and control should be carried out by a 

qualified  electrician  staff,  who  act  in  ac-

cordance with the service manual and the 

device functions. Before installation make 

sure the connection cables are not under 

voltage.

• Improper transport, storage, and use of 

the device influence its wrong functioning. 

It is not advisable to install the device in 

the following cases: if any device part is 

missing or the device is damaged or de-

formed. In case of improper functioning of 

the device contact the producer.

GPRN heating cable - set includes:

•  one-sided power supply heating cable connected with power supply cable, 

•  installation instruction with the Warranty Card. 

A temperature controller 

is an essential element used to control the GPRN heating cable. It is used 

to connect the heating cable with electric installation. It is important to choose a correct temperature 

controller with regard to the application of a heating cable and its function. The ZAMEL Sp. z o.o. 

company offers the application of temperature controllers by EBERLE.

It is advisable to choose a temperature control-

ler in accordance to power of the connected 

heating cable as well as to the placement of 

the heating cable and measurement probes.

To control temperature, a controller keeping a 

constant temperature or a controller with a pro-

grammer needs to be used and which allows 

for the adjustment of heating parameters.

Depending on the function the heating system 

with a temperature controller shall realise, the 

following sensors are applied: temperature 

sensors, ice and snow sensors, temperature 

and humidity sensors.

The connection of the heating cable with 

a temperature controller should be done 

in accordance with a diagram described 

in the temperature controller manual in-

struction.

REMARKS

• During installation it is required to follow in-

structions included in the Heating Cable Ma-

nual Instruction.

•  Temperature controller’s installation must be 

done according to temperature controller In-

stallation Manual.

• It is forbidden to mount the cable on pins, 

bolts,  screws  or  other  fixing  elements  that 

can damage the outer coating of cables.

•  The  cable installation surface must be smo-

oth with no sharp edges or sharp fixing ele-

ments.

•  Heating unit cannot be mounted on non-uni-

form bases.

• Heating cable should not be installed in pla-

ces with permanent building.

• Heating cable resistance should be measu-

red twice: after opening the package and 

before installers’ work  and also after placing 

the heating cable in an appropriate place.

•  Ensure the sub-floor is dust and sharp ele-

ments free.

• Don’t install the heating cable if the ambient 

temperature is below + 5°C.

• Don’t cut the heating cable or its connection 

with power supply cable.

•  The heating cable should not undergo exces-

sive strain and should be protected against 

sharp device damage.

• Heating unit must be supplied by means of 

a device from TN-S electric circuit with RCD 

(residual 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 mi-

nimum distance between the heating cables 

must not be less than 5-times the diameter.

•  It is required to make a draft or add pictures 

of 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.

• The non-detachable supply cable cannot be 

replaced. If the cord is damaged, the equip-

ment is useless. The power supply cable can 

be shortened to the desired length, necessa-

ry for mounting the temperature controller.

•  The device is not intended to be used by pe-

ople (children) with limited physical, feeling 

or psychic ability or people without experien-

ce 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.

•  The radius of heating cable bending shall not 

be less than 8 times of its diameter.

• The heating cable cannot be permanently 

immersed in any liquid.

•  The heating cable must be used in accordan-

ce with manufacturer’s specifications.
