You can connect the collector hose to the heat pump with one or more circuits. In a multi-circuit solution, the collector
hoses are connected in parallel as illustrated below. The parallel hoses are connected to two distributors. Each coil should
have a shutoff valve and a control valve. The control valve is adjusted so that the fl ow rate is the same in the coils.
After the distributor and the valves, the coils are connected to a collecting pipe. A fi lling unit, particle fi lter and an
expansion vessel are connected to the collecting pipe. A safety valve is connected to the outgoing pipe. The safety valve
leads off any overpressure.
One circuit at a time is fi lled with heat transfer fl uid. Keep the valves closed in the other loops during the process. Read
