EXAMPLES OF HEATERS CONNECTION
Connecting a heater to a rating circuit
The heater is placed on the ground, next to the heating source, or in its vicinity.
The heating circuit is
connected to marked inputs and outputs of the heater exchanger; the deaerating valve is mounted in the
highest place. It is necessary to
install a filter into the circuit in order to protect the pumps, the three
-
way
valve, and 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 HSW using a three
-
way valve, always follow the installation
instructions of the three
-
way valve’s manufacturer.
