“Flooded-condenser” Head-pressureControlSystem
The Liebert Lee-Temp system consists of a modulating-type head-pressure control valve and insulated
receiver with heater pad to ensure operation at ambient temperatures as low as -30°F (-34.4°C). The
Liebert Lee-Temp system can be used with any compressor or expansion-valve choice.
A discharge line and liquid line must be field-installed between the indoor unit and the outdoor
condenser. See the appropriate piping schematic, listed in Table 6.1 on page33.
