  • Page 64 LogiCool InRak™ IT Cooling Installation Liquid Line If the system is configured with the InRak higher than the condenser unit it may be required to increase the degree of sub cooling to prevent flashing gas occurring in the liquid line. This flashing is due to excess pressure drop caused by the static head of liquid refrigerant and can result in poor operation of the evaporator and expansion device.
