Compared to the direct return system in image 2 where the return header is connected to the load closest to the pump, the reverse return system distributes the flows and pressures more evenly. Occasionally, a foot valve can be installed on the inlet pipe to maintain pump prime or to protect it from reverse rotation.
The temperature and pressure in the compressor rise, and it moves towards the condenser coil to reject the heat outside. Check valves may also be used in lines feeding a secondary system in which the pressure can rise above that of the primary system. A good way to do this is with a dremel.
Next, shut down the driver and leave the suction valve open. In typical air conditioners, the refrigerant absorbs the heat inside the house in the evaporator coils. This pump is designed to function with most standard unpumped ro systems.
