What is important for running the pump P 6.1L in the cold room?

P6.1L LPG Pump

The pump P 6.1L should never be turned off when running in the cold room! If the pump is turned off it will cool down too much, which can result in the magnetic valves getting stuck and therefore an accurate mixing can not be guaranteed. By keeping the pump at least in standby mode the pump is kept at working temperature, which will prevent this behaviour. This is espeacially important for LPG pumps. Also keep in mind that the temperature should not fall below 4°C at all in the cold room to ensure good working conditions for the system. Depending on the air humidity you may also have to switch off leak management of the pump.
