Additional insulation for the balance of the
liquid and suction lines is recommended
wherever condensation drippage is objection-
able or lines are exposed to ambient conditions.
SUCTION LINE
• Pitch in direction of flow.
• May be reduced by one size at one third of
merchandiser run load and again after the
second third. Do not reduce below the
merchandiser suction line size.
• Merchandiser suction lines should enter at
the top of the branch line.

the merchandiser run load. Do not reduce
below the merchandiser liquid line connec-
tion size.
