2.4 CONNECTION OF TANK TO HOT WATER DISTRIBUTION SYSTEM
The tank is placed on the ground, next to the heating source, or in its vicinity. The heating circuit shall be
connected to marked tank exchanger inputs and outputs, and bleeder valve installed at the highest point.
It is necessary to install a filter into the circuit in order to protect pumps, three-way valve, backflow flaps
and the exchanger from sedimentation. It is recommended to flush the heating circuit before the assembly.
All wiring connections must be properly insulated from heat. If the system works with priority heating
of HUW using a three-way valve, always follow the installation instructions of the three-way valve's
manufacturer.
