INSULATION
The suction and liquid lines should be clamped or
taped together and insulated for a minimum of
30 ft (9144 mm) from the merchandiser.
Additional insulation for the balance of the liquid
and suction lines is recommended wherever con-
densation 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).
