Connection kit for frost protection

Our Single Cool with frost protection pipes are equipped with a self-regulating 10 W/m heating cable to prevent stagnant water from freezing.

Description

The heating cable is AC powered, and must be connected to a 220 VAC/50-60 hertz line to operate. The power line requires over-current protection through a 16A 30mA RCD (residual-current device). To prevent the 10 W/m heating cable from dissipating energy when surrounding temperatures are well above the freezing point, the use of an ambient thermostat to automatically interrupt the power supply at a pre-set temperature (e.g. 2°C) is recommended.

The total length of the heating cable should not exceed 100 m. Where longer heating cables are required, separate power supplies should be foreseen, each feeding maximum 100 m cable.

The heating cable can be cut to any desired length (< 100 m and as a function of the pipe length). To assure proper functioning of the cable, and to prevent possible short circuits, the cables’ two conductive wires should be electrically insulated from each other.
