Installation Instructions Section 2
2-22
Part Number 000002477 3/08
C. SUCTION LINE OIL TRAPS
0 to 20 feet (0 to 6.1 m) Rise: The ice machine head
section has one oil trap built in which allows for a
maximum condenser rise of 20 feet (6.1 m) without
additional traps in the suction line.
21 to 35 feet (6.4 to 10.7 m) Rise: The suction line
requires an additional Oil Trap (“S” type) to be installed.
Install the trap as close as possible to midpoint between
the ice machine head section and CVD condensing unit.
S-Trap Kits are available from Manitowoc (refer to chart).

Service Loop
A service loop in the line set permits easy access to the
ice machine for cleaning and service.
• 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.
Step 3 Lengthening or Reducing Line Set Lengths
When the line set required shortening or lengthening, do
so before connecting the line set to the ice machine
head section or the CVD condensing unit.
Do not form unwanted traps in refrigeration lines.
Never coil excess refrigeration tubing.
