4.2. Main Exchanger Tank
Subject
Description
Function of Part
It provides a heat exchange environment between
the resistors mounted on it and the installation water.
Impact in Case of Malfunction
In case of water leakage, it may cause pressure drop in
the plumbing and short-circuits in the device.
Main Associated Error Codes
Diagnostics and Test Method
It should be checked whether there is any wear that may
cause water leakage by observing the resistor, duct,
purge
and valve connection flanges.
Maintenance Requirement
In the annual routine maintenance, the exchanger is
cleaned by circulating Sentinel X300 through the
central heating installation.
Test definition
Test Method
Observation of Tank Water Leakage
Cause
Make sure that the water leakage in the tank is not
caused by the mounted resistor,
purge
, duct or
valves that are not tightened with sufficient torque.
Then visually inspect the corresponding flange of the
tank. The o-ring specified in the spare parts catalogue
must be used in the resistor assembly.
