English to Russian Tech/Engineering Mechanics / Mech Engineering Brix the valve

Из описания автомата приготовления газированной воды. По тексту встречается brix cup (специальная чашечка, с помощью которой можно регулировать, сколько воды и сиропа должно быть). Но далее brix уже встречается как глагол, и мне не совсем понятно, что с ним делать.
There are four cup sizes: small, medium, large and extra large. Each cup size needs to be programmed separately. Set the flow rate first and then brix the valve. By doing so, you will be sure to set times that match your desired flow rate. Once the valve is brixed, you can replace the valve cover because the times (cup sizes) are all set from the front switch pad.
Reset the flow rate and re-brix the valve. Look for foreign matter in the adjustment screws, flow controls or pallet seats.
Sometimes if a system is not flushed completely at startup, foreign particles, etc. will be introduced into the system.
