Important Information Prior to Installation ³ Read Installation, Use & Care Manual S Model QuietQube ice machines cannot be stacked. Failure to follow installation guidelines may affect warranty coverage. Manitowoc remote systems are only approved and warranted as a complete new package. Warranty on the refrigeration system will be void if a new ice machine head section is connected to pre-existing (used) tubing or condensing units or vice versa.

Electrical Service Requirements ³ All electrical work, including wire routing and grounding, must conform to local, state and national electrical codes. The following precautions must be observed: The ice machine must be grounded. ³ A separate fuse/circuit breaker must be provided for each condensing unit. ³ A qualified electrician must determine proper wire size dependent upon location, materials used and length of run (minimum circuit ampacity can be used to help select the wire size).

Line Set Length, Rise & Drop LINE SET LENGTH 100 feet (30.5 m) Length: The maximum measured length the line set can be. The receiver is designed to hold a charge sufficient to operate the ice machine in ambient temperatures between 20°F (-28.9°C) and 130°F (54.4°C)*, with line set lengths of up to 100 feet (30.5 m).
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. See chart below for kits.
Line Set Installation ³ Route refrigeration tubing ³ The maximum measured length the line set can be is 100’ (30.5 m) (no exceptions) ³ The maximum amount of line set which can be exposed on the rooftop is 25% of the total length of the line set.
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.
Secure Line Set ³ Secure Line Set as Needed ³ Do not crush/compress insulation
Connect the Line Set Ice Machine The line set can be routed for entry through the top or rear of the ice machine head section. ³ Top routing requires the cover to be trimmed. ³ Rear routing may require the use 90° elbows on some models. The line set shut off valves at the back of the ice machine must remain closed and be protected from heat during the brazing process. Wrap the valves in a wet rag or other type of heat sink prior to brazing.
Connect the Line Set Condensing Unit ³ The condensing unit ships from the factory pressurized with a 50/50 mixture of nitrogen/helium. Bleed off pressure from both suction and liquid line access ports prior to cutting into refrigeration lines. ³ The compressor oil rapidly absorbs moisture. Be prepared to complete line set installation and start your evacuation process in order to minimize the time the compressor is exposed to the atmosphere.
Pressure Test & Evacuate Leave the line set shut off valves closed (front seated). Pressure test the line sets and CVD condensing unit with 150 psig of dry nitrogen. Add nitrogen at the line set shut off valves located at the back of the ice machine. Complete the pressure test, verify no leaks are present and remove the nitrogen from the system before connecting the vacuum pump. Connect a vacuum pump to both of the line set shut off valves located at the back of the ice machine head section.
Open the Valves Prior to Starting Open The Valves Prior To Starting The Ice Machine. A. Slowly backseat (open-turn counterclockwise) the suction line shut off valve. B. Slowly backseat (open-turn counterclockwise) the liquid line shut off valve. C. Slowly backseat (open-turn counterclockwise) the receiver service valve. NOTE: You will not hear refrigerant flow when the valves are opened. Refrigerant will not flow until the toggle switch is placed in the ice position and the solenoid valve opens.
Leak Check the System ³ Leak check the new line set connections at the ice machine head section, condensing unit and S trap as well as all factory joints throughout the entire system. ³ Disconnect power to the CVD condensing unit. Place the ICE/OFF/CLEAN toggle switch into the ICE position. This allows the low side and high side pressures to equalize. ³ Place the ICE/OFF/CLEAN toggle switch in the OFF position. Connect power to the CVD condensing unit and allow system to pump down.
Insulation Requirements The following insulation requirements prevent condensation at 90°F (32.2°C) ambient 90% Relative Humidity. If higher humidity is expected, increase insulation thickness. Suction Line Liquid Line 3/4 inch (19.1 mm) 1/2 inch (12.7 mm) 5/8 inch (15.9 mm) 3/8 inch (9.5 mm) 7/8 inch (22.2 mm) 5/8 inch (15.9 mm) Min.
Refrigerant Charge The ice machine is pre-charged with refrigerant. Additional refrigerant may be required on some models, when the line set length is between 50’ - 100’.
