Page 5 Pipework Schematic size 9 and 16 units Each heat pump has 1 inch BSP male connections; these should be connected to flexi hoses. The flexi hoses have to be insulated to conform to MCS. You cannot combine the flow of the units together without a low loss header or buffer.
Page 6 Buffer vessels, heat exchangers and low loss headers You don’t have to use a buffer vessel on a Samsung but we do need a minimum flow rate of 17l/min and have a circulating volume of over 20 Litre. To achieve this is much easier if you break the system in two with a header, a buffer or a heat exchanger.
Page 10 Wiring and Power Supply Information: Master Power The EHS system needs 2 power supplies: One connects into the outdoor unit, 20 Amp for the 9kW and 32 Amp for the size 16 The one for the control box is 3 Amp and wires into A1 and A2 on the PCB, the breaker must be removed.

Using the power flusher fill the system with water and 25% Propylene Glycol to more than 1 bar.
