2.7.5 P&I diagram for CFLE units
IMPORTANT
No insulation on liquid line! 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 sub-cooling desirable for the liquid refrigerant before
it enters the expansion valve. Insulate both the suction and liquid
interconnecting piping between the [ CF ] EASY unit and the evaporator.
