1/200 to 1/250. Upper and lower oil traps, double risers and reduced pipe diameters may be required
f or suction lines where long vertical risers cannot be avoided.
All pipes should be adequately supported to prevent sagging which can create oil traps. The
recommended pipe clamp support distance is shown in Table 21 below:

NOTE: It is strongly recommended to insulate both the suction and liquid interconnecting
piping between the OLTE unit and the evaporator.
