For regular and cost-effective operation of the user modules, they must be periodically checked and overhauled appro-
ximately once every two years.
The stainless steel plate DHW exchanger is easily disassembled with a screwdriver by operating as described below:
• Close all the on/off taps on the hydraulic connectors of the unit;
• Drain the heating circuit
through the drain tap
;
• Drain the domestic hot water system, opening a hot water tap;
• Remove the two screws at the front securing the water-water heat exchanger and pull it out.
To clean the exchanger and/or DHW circuit, use Cillit FFW-AL or Benckiser HF-AL.
