INSULATION
Additional insulation for the balance of the liquid
and suction lines is recommended wherever
condensation drippage is objectionable or lines
are exposed to ambient conditions.
SUCTION LINE
• Pitch in direction of flow.
• May be reduced by one size at one third of
case run load and again after the second third.
Do not reduce below the case suction line
size.
• Case suction lines should enter at the top of
the branch line.
LIQUID LINE
• May be reduced by one size after one half the
case run load. Do not reduce below the case
liquid line connection size.
• Take-offs to case liquid lines should exit the
bottom of the branch liquid line. Provide an
expansion loop for each evaporator take-off
(minimum 3 in. [76 mm] loop).
