HEATING MAIN MONTAGE INSTRUCTIONS CV4.04
6. Insulation, wire loop resistance and wire
connection check should be performed
at every pipe connection. Record all
readings taken in the journal.
100 m long wire resistance should be
1,3
Ω
±15%.
Assembled pipe network should not
have resistance of less than 200 k
Ω
.
7. At the end of the pipe network where
pipes are not going to be connected to
further connected pipes should be
connected in a loop and should be
secured to the insulation, eliminating
any chance of contact with steel pipe.
8. Control and measurement of alarm
system wires is possible by connecting
wires to the alarm box with the help of 3
lead connection cables. Cable main wire
should be connected to the steel pipe
with help of screw M8 and a wrench.
Alarm boxes are installed close to the
pipes entry in the house and/or heating
chamber.
It is advised to place shrinkable cap at
the end of the pipe to protect PUR
insulation and alarm wires. Also,
connect joining cable to alarm wires
underneath the cap.
Alarm system should be supervised at all time with acquired CWA 6000 systems (Sweden)
or other similar type equipment. Impulse reflection method is used for specific incident
place determination. Such equipment is available at „Poliurs” Ltd.
After alarm system montage and testing the supervisory alarm acceptance act should be
filled out (for act example see Addition Nr. 4). Keep in storage installation act and journals.
