NOTICE If using copper and galvanised steel tubes always observe the sequence in the flow direc tion Copper after galvanised steel Avoidance of heat losses In order to minimise heat losses plan the water lines as short as possible and include thermal insu lation Have the lines installed by a professional Sanitary installation The direct connection with a stainless steel tank must never be produced from copper or galvan ised If a stainless steel tank is connected with a galvanised cold water line with the requisite fit tings or threaded connections then a fine filter must be fitted upstream of the stainless steel tank in order to protect against rust particles etc Brass red brass plastic and stainless steel are all suit able connection materials If a stainless steel storage tank is connected with a galvanised or copper line then it is necessary to fit a red brass or brass fitting between these parts 16 It is possible to dispense with the use of a false anode if the chloride content in the drinking water is lt 150 mg l Always install a pressure reducer in the cold water line Pressure reducer Always install a pressure reducer in the cold water supply line Safety valve The safety valve prevents positive pressure from building and serves to drain off the excess water which occurs due to expansion of the storage tank contents when heated Only install a type approved membrane saf
