In this machine for frost protection on the output tube evaporator mounted flow switch. In the absence of fluid flow switch sends a signal to the system control machine, which stops the compressor.Unit is designed and manufactured for use water-ethylene glycol mixture.USE ONLY GLYCOL MIXTURE EFFECTIVE WAY TO PROTECT FROM FREEZINGAt lower ambient temperatures, water-glycol mixture should have a corresponding concentration for guaranteed protection and to prevent ice formation. Recommended protection - lowering the freezing temperature at least 15F (8.3 °C) below the minimum ambient temperature and no less than 20F (11 °C) below the coolant temperature at the outlet of the evaporator.Observe appropriate caution when using antifreeze based on ethylene glycol and propylene glycol. When interacting with oxygen there is a risk of corrosion.Attention! Electrolytic corrosion. Pay special attention to the problem of electrolytic corrosion caused by improper grounding.
