CONNECTION OF TANK TO HOT WATER DISTRIBU
TION
SYSTEM
The tank is placed on the floor next to the heating source or in its proximity.
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.
