  • Page 4: Combat Lime Precipitation

    EN 4 Combat lime precipitation in the boiler and heat exchanger Completely desalinated water no longer contains any substances that can damage or settle in boilers and heat exchangers. The following table shows the amount of lime that accumulates as a result of filling the heating system once with untreated water.
  • Page 5: Combat Corrosion

    5 EN Combat corrosion Since corrosion processes in closed heating systems mainly involve electrochemical reactions, the electrical conductivity of the water plays a direct role in the rate of these reactions. The salt content of the water determines the electrical conductivity. According to VDI guideline 2035, increasing amounts of oxygen are tolerated with reducing water salt content.
  • Page 6: The Function

    6 EN The function Heating and cooling systems use water as a medium for heat transfer. The water circulates from where the warm water is generated to the user and back. Even if the system always re-uses the same water, lime and aggressive materials enter the closed water system when first filling the system, which can damage modern components.
  • Page 7: Connection Variations System Fill-Up

    PUROTAP easy may only be under pressure for the duration of filling. Temp. max. 60 °C, pressure max. 6 bar.
  • Page 8: Connection Variations System Cleaning

    The apparatus contains a non-return valve. When the connections are turned, the untreated water cannot flow through the apparatus. PUROTAP easy is to be connected to the pressure side of the auxiliary pump. If this cleaning variation is conducted during heating operation, then the apparatus temperature may only reach a maximum of 60 °C for a short time.
  • Page 9: Operating The Meter

    9 EN Operating the combined meter The combined meter is battery-operated. It measures the flow rate in l/min, the total volume in litres and the concentration of dissolved minerals, either in microsiemens or TDS. In addition, a limit can be set for the maximum concentration of minerals tolerated in the demineralised water (appliance outlet).

    Litres of demineralised (completely desalinated) water per from the adjacent table, or calculated cartridge with the capacity figure of the resin °fH amount. PUROTAP easy resin filling °dH has a capacity of 35 m at 1°fH, and/or 50° 28° 20 m at 1°dH.
  • Page 11: Change Ion Exchanger Resin

    11 EN Change ion exchanger resin If the content of dissolved solids in treated water increases over 30 TDS and or 45 µS (approx. 2 °fH) according to the meter, then the resin needs to be changed. We first recommend that the water supply is shut-off shortly, shake the cartridge and then slowly turn the water supply back on and fill-up.
  • Page 12 12 EN b) Fill with new resin 1. Screw the cap back on the bottom of the resin container for fill-up. 2. Cut the corner of the resin sack open and fill the resin in. Only use original mixed resin. 3.
  • Page 13: Empty Water

    1. Loosen the cap on the bottom of the bottle. Draining contains a fine sieve, so that resin cannot leak out. Check that the fine sieve is correctly installed. 2. Turn PUROTAP easy and let water drain out. 3. Replace cap.
  • Page 14: Repair Malfunction

    14 EN Repair malfunction The automatic shut-off of the meter serves to conserve the The meter display goes off after batteries. In manual mode, the ON button much be pressed approx. 10 seconds. for each measurement. Alternatively, auto mode can be used (press the ON button two times), then each of the last measuring values are permanently displayed.
  • Page 15 15 EN The apparatus has 2 fine sieves for preventing ion exchanger resin The flow is weak despite the from leaking into the heating system. unrestricted supply line Check the fine sieve in the outlet and on the immersion hose regu- larly.
