If in any doubt, please call the appropriate help desk. Disregarding the instructions given in this manual in its entirety and any relevant regulations, standards and codes of practice will void the guarantee of this product. -
Page 10: Siting Considerations
- frost protection The Dimplex SCxn cylinder range is designed to be floor standing, vertically mounted, indoors and in a frost free environment. The cylinder may be located on any flat and level surface, provided it is sufficiently robust to support the weight of the cylinder when full of water (see chapter 10). - Page 11 Unvented hot water cylinder – SCxn…d/i, SCxn…sd/si WATER It is recommended to install a drain valve in the lowest point of the cold water feed to the cylinder. This allows the cylinder to be drained in a controlled manner should this become necessary.
