K 3® W

Unplug the appliance and drain all the contents, rinse with water. Prepare sufficient ones for cleaning the heat exchangers amount of K 3® W solution in water - the recommended dilution ratio is 8–40% (0.8–4 kg K 3® W per 10 l of water). Heat the solution to 45 ° –55 ° C and let it circulate for approx. 10–15 min, continuously check the pH and keep it in the interval of 1.5–2.0 K 3® W additions (for 1-2 hours). After cleaning and descaling, rinse the entire system with the product NOVALON® 2000 (dilution 1: 5 with water) and then with pure water so that the pH of the effluent solution corresponds to the pH of pure water. You can reconnect the heat exchanger to the circuit or preserve and shut it down.
