SERVICE LOOP
• The supplied service loop (on Ice Beverage ice
machines) is an installation requirement.
Excess tubing length must be sufficient to
allow 180° rotation of the ice machine.
• 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.
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 4 Lengthening or Reducing Line Set Lengths
When the line set requires shortening or lengthening,
do so before connecting the line set to the ice machine
head section or the CVD
Do not form unwanted traps in refrigeration lines.
Never coil excess refrigeration tubing.
Step 5 Connecting the line set.
To prevent oxidation of the copper, purge line set and
condensing unit with dry nitrogen while brazing.
The ice machine head section contains refrigerant
charge. The ice machine head section contains
three (3) refrigeration valves that must remain
closed until proper installation of the line sets is
completed.
