Sight glass Sight glass of liquid each contour line should be checked once a week to determine the state of the refrigerant. Clear sight glass and the presence of a solid transparent refrigerant flow indicates that the unit is properly charged to ensure the optimal functioning of the TEV. Bubbling refrigerant at a well-established mode of operation of the system indicates nedozapravku refrigerant charge. The emergence of gaseous refrigerant may indicate an excessive loss of pressure in the line of fluid due to contamination of the filter-dryer or the presence of obstacles in a different place through the liquid. For a small value of supercooling, refill system to clean the sight glass. In the case of boiling at an acceptable value of hypothermia check the pressure drop in the filter-drier. Sight glasses fitted with moisture indicator, which shows the level of humidity in the circuit by changing the color. If after the 3 hours of the unit indicates the presence of moisture in the system, it is necessary,
