Each circuit must be protected with
a residual current device.
Disconnect all circuits before undertaking
any installation or maintenance works.
Keep the termination points of the heating
cables, power supply conductors and all
subcomponents of the sets in dry condition
before and during any installation works.
Use only in places of low vulnerability
to mechanical damage.
Connect the heating cable’s shield with
the proper grounding terminal.

The design of electrical heating systems
must be executed according to the design
directives for explosive conditions, basing
on the manufacturer’s recommendations
and supervised by qualified experts.
Heating systems must be executed in full
accordance with the instructions herein,
and the installation must be performed
by an authorised electrician.
Before undertaking any maintenance
works/repairs/ alterations, read the
specification of the heating system.
The specification of the heating system
should be stored for any heating circuit,
as long as the system is in use.
Note:

CACM25-PROi
Electrical systems must be checked
before the first start-up.
Anti-frost systems must be checked
before each heating season.
Regularly check systems for maintaining
process temperature, min. twice a year.
Note:

Place the gland with the oval opening gasket
on the heating cable, following the sequence
shown in the picture, in the distance of min.
300mm from the beginning of the cable.
Split the cable sheath delicately along the length
of 170mm, not damaging the protective screen.

Split the heating element open revealing the
conductor wires along the length of 140mm.
A8
The splits should be made so that the
conductor wires are not damaged with
the blade of the utility knife or the side
cutter.
Note:

Pull on the 180mm-long auxiliary insulation
tubes covering silicone tubes, as well as the
150mm-long double silicone insulation tubes.
Pull the auxiliary tubes on so that the
conductor wires remain twisted.
Note:

13
Pull the common part of the double silicone
tubes onto the earlier uncovered electric
insulation of the heating cable, along the length
of 20mm.
Rotation might cause the short circuit
of the conductor wires.

Note:

14
Put the green-yellow 160mm-long tube onto
the twisted protection screen.
Pull out the auxiliary tubes covering the 180mm-
long tubes and save them in case any
modification of the heating circuit becomes
necessary.

Align the conductor wires and twisted
protective screen, leaving the wires isolated
along the length of 12mm.
If necessary, shorten the silicone insulation
tubes by a max. 40 mm.
Enter the prepared heating circuit, together
with the components recreating insulation,
into the electrical box through the counter nut
so that the heating cable’s sheath is inserted
into the box along the length of 10mm.
Tighten the barrel nut and the counter nut
of the M25 gland.
Enter the conductor wires and the braided
screen into the adequate terminals.
