Service Loop
A service loop in the line set permits easy access to the
ice machine for cleaning and service.
• A service loop is not considered an oil trap.
• The service loop is not included when calculating
length, rise or drop of the tubing run.
• Do not use hard rigid copper for the service loop.
! Caution
If a line set has a rise followed by a drop, another rise
cannot be made. Likewise, if a line set has a drop
followed by a rise, another drop cannot be made.
Step 3 Lengthening or Reducing Line Set Lengths
! Caution
Do not form unwanted traps in refrigeration lines.
Never coil excess refrigeration tubing.
When the line set requires shortening or lengthening, do
so before connecting the line set to the ice machine
head section or the remote condensing unit.
