Compressor requirements: 1.2 to 2 GPM (4.5-755 LPM) flow rate

Operating temperature range, standard: 190° to 210°F (88°- 99°C)

Thermal oil bypass valve, standard setting: 200°F (93°C)

Thermal bypass valve operation (valve’s purpose is to provide discharge temperature control)

Oil flow on valve is A to B when the unit is cold and A to C when the heat rises (see Figure 9).
