1.3 Never

– Install Therma Cable sections so that the heating cables are less than 76 mm (3”)

from each other. The temperature could be too high and could cause damages;

– Shorten or alter any part of the heating cable (Fig. 1.3);

– Cross, overlap, or stack heating cables (they must not touch);

– Connect a 120V product to a 240V/208V power source;

– Use a bending radius under 20 mm (¾”);

– Install a temperature regulator (thermostat or other) where it is accessible from the

shower or bath (install at least 1 m [3’ 4”] away);

– Staple heating cable or floor sensor end to the subfloor (Fig. 1.3);

– Install the Therma Cable system if the safety seal is broken;

– Install the Therma Cable system under a closet or fixed items.

– Series heating cable sets shall not extend from beyond the room or area in which

they originate;

– Series heating cable sets are not to be installed in walls.

– Exceed the 15 Amp limit per thermostat or power unit if you intend to add a OTR

product to one of them. Please refer to the related OTR table products to deter-
mined if the amperage limit was reached or not, by adding a OTR product to the
thermostat or power unit (or relay). If the amperage limit is over 15 Amp then you
will need to add a power unit for the additional product needed in this room.
