2.8.2 P&I diagram for ZXLE units
IMPORTANT
Absence of insulation on the liquid line in ZXLE units! Air moisture
condensation and lack of performance! Moisture will condensate on the
liquid line and cause water droplets. The liquid line can pick up additional
heat from the ambient which will adversely affect the subcooling desirable for
the liquid refrigerant before it enters the expansion valve. Both the suction
and liquid interconnecting piping between the unit and the evaporator should
be insulated to avoid condensation.
