Ice machines, like other refrigeration equipment, reject heat through the condenser. It is helpful to know the amount of heat rejected by the ice machine when sizing air conditioning equipment.

This information is also necessary when evaluating the benefits of using water-cooled or remote condensers to reduce air conditioning loads. The amount of heat added to an air conditioned environment by an ice machine using a water-cooled or remote condensing unit is negligible.

Knowing the amount of heat rejected is also important when sizing a cooling tower for a water-cooled condenser.

Water and Drain Requirements

POTABLE WATER REQUIREMENTS

Follow these guidelines to install water inlet lines:

• Do not connect the ice machine to a hot water supply. Be sure all hot water restrictors installed for other equipment are working. (Check valves on sink faucets, dishwashers, etc.)
• If water pressure exceeds the maximum of 80 psig (552 kPA) recommended pressure, obtain a water pressure regulator from your local plumbing supply house.
• Install a water shut-off valve and union for both the ice making and condenser water lines.
  • Insulate water inlet lines to prevent condensation.
• Plumbing must conform to local codes.

Caution

Do not apply heat to water valve inlet fitting or over-tighten. This will damage plastic water inlet connection.

DRAIN CONNECTIONS

Follow these guidelines when installing drain lines to prevent drain water from flowing back into the ice machine and storage bin:

• Drain lines must have a 1.5 inch drop per 5 feet of run (2.5 cm per meter), and must not create traps.
• The floor drain must be large enough to accommodate drainage from all drains.
• Run separate bin and water-cooled condenser drain lines. Insulate them to prevent condensation.
• Vent the ice machine drain to the atmosphere. The ice machine drain requires an 18" (46 cm) vent. Do not vent the condenser drain on water-cooled models.
• Drains must have a union or other suitable means to allow in-place disconnection from the ice machine when servicing is required.

COOLING TOWER APPLICATIONS

A water cooling tower installation does not require modification of the ice machine. The water regulator valve for the condenser continues to control the refrigeration discharge pressure.

It is necessary to know the amount of heat rejection, and pressure drop through the condenser and water valves (inlet and outlet) when using a cooling tower on an ice machine.

• Water entering the condenser must not be lower than 37^ F ( 3^ C) or exceed 90^ F ( 32^ C).
• Water flow through the condenser must not exceed 5 gal. (19 L) per minute.
• Allow for a pressure drop of 7 psi (48 kPa) between the condenser water inlet and the outlet of the ice machine.
• Water exiting the condenser must not exceed 110°F (43°C).

Electrical Service

▲Warning

All wiring must conform to local, state and national codes.

VOLTAGE

The maximum allowable voltage variation is ±10% of the rated voltage at ice machine start-up (when the electrical load is highest).

▲Warning

The ice machine must be grounded in accordance with national and local electrical codes.

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.
• A separate fuse/circuit breaker must be provided for each ice machine.
• 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).
• Check all ground screws in the control box and verify they are tight before starting the ice machine.

Important

Observe correct polarity of incoming line voltage. Incorrect polarity can lead to erratic ice machine operation. L1 is the wire colored brown and L2/N is the wire colored blue.

FUSE/CIRCUIT BREAKER

A dedicated circuit and a separate fuse/circuit breaker are required for each ice machine.

GROUND FAULT CIRCUIT INTERRUPTER

We do not recommend the use of a GFCI/GFI circuit protection with our equipment. If a GFCI/GFI is required by code, use a GFCI/GFI breaker rather than outlet which is more prone to intermittent nuisance trips than panel circuit breakers.

MINIMUM POWER CORD SPECIFICATIONS

The wire size to the receptacle is dependent upon location, materials used, length of run, etc., so it must be determined by a qualified electrician. Local, state or national requirements will supersede our minimum requirements.

FOR UNITED KINGDOM ONLY

As the colors of the wires in the mains lead of the appliance may not correspond with the colored markings identifying the terminals in your plug, proceed as follows:

• The wire which is colored green and yellow must be connected to the terminal in the plug which is marked with the letter E or by the earth ground symbol by colored green or green and yellow.

- The wire colored blue must be connected to the terminal which is marked with the letter N or colored black.

- The wire colored brown must be connected to the terminal which is marked with the letter L or colored red.

If required, cut a 3-inch (76.2 mm) circular hole in the wall or roof for routing of refrigeration tubing. A qualified person must perform all roof penetrations.

Step 2 Route Refrigeration Tubing

Properly route refrigeration tubing between the ice machine head section and the remote condensing unit.

A. 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 120^ F ( 48.9^ C), with line set lengths of up to 100 feet (30.5 m). The maximum amount of line set which can be exposed on the rooftop is 25% of the total length of the line set.

Important

QuietQube ^® ice machines will not function with line sets greater than 100 feet (30.5 m). Do not attempt to go beyond this distance and add refrigerant charge to compensate!

B. LINE SET RISE OR DROP

35 ft. (10.7 m) MAX. DISTANCE

35 feet (10.7 m) Rise: The maximum distance the remote condensing unit can be above the ice machine.

15 ft. (4.5 m) MAX. DISTANCE

15 feet (4.5 m) Drop: The maximum distance the remote condensing unit can be below the ice machine.

C. SUCTION LINE OIL TRAPS

Caution

Do not form unwanted traps in refrigeration lines. Never coil excess refrigeration tubing.

0 to 20 feet (0 to 6.1 m) Rise: No oil trap is required when the condensing unit is located 20 feet (6.1 m) or less above the ice machine head section.

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 remote condensing unit. S-Trap Kits are available from Manitowoc.

21 ft. (6.4 m) OR MORE RISE ADDITIONAL TRAP KIT REQUIRED

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.

Step 4 Connecting the line set

To prevent oxidation of the copper, purge line set with dry nitrogen while brazing.

A. Connect the Line Set to the Remote Condensing Unit

The condensing unit is shipped with a refrigerant charge. The line set shut-off valves must remain closed during brazing. Protect the valves from heat during the brazing process. Wrap the valves in a wet rag or other type of heat sink prior to brazing. Cool braze joint with water immediately after brazing to prevent heat migration to the valve.

MINIMIZE THE TIME THE REFRIGERATION SYSTEM IS EXPOSED TO THE ATMOSPHERE (15 MINUTES MAXIMUM) SUCTION LINE LIQUID LINE

B. Connect the Line Set to the Ice Machine Head Section

• Cut the suction and liquid tubing with a tubing cutter, leaving enough tubing to easily braze.
• Connect the line set.
• Cool braze joint with water immediately after brazing to prevent heat migration.

Step 5 Pressure Test and Evacuate Line Set and Ice Machine Head Section

• Pressure testing and evacuation can be performed from the ice machine head section or CVD condensing unit shut-off valves.
• Schrader valve core removal tools that allow for removal and installation of the valve cores without removing manifold gauge set hoses are recommended to decrease the evacuation time.
• Pressure test @ 150 psi (1000 kPa) for a minimum of 15 minutes.
  • Minimum evacuation level is 500 microns.

Step 6 Open the valves and leak check the refrigeration system prior to startup of the ice machine

A. Backseat (open-turn counterclockwise) the suction shutoff valve.
B. Backseat (open-turn counterclockwise) the liquid line shutoff valve.

Disconnect power to the remote condensing unit. Confirm water is supplied to the ice machine, then place the ice machine rocker switch in the ON position. The water trough will fill and initiate an 8 minute delay period. When the 8 minute delay period ends the liquid line solenoid valve will energize and equalize the low side and high side pressures. Leak check the line set connections, S trap and all factory joints throughout the entire system. When the leak check is complete, place the rocker switch in the OFF position. Connect power to the remote condensing unit and allow system to pump down.

Verify suction and liquid line

Verify suction and liquid line shut-off valves are open before operating the ice machine

Important

All refrigeration valve caps must be reinstalled to prevent future refrigeration leaks.

Verify O-ring in Schrader valve caps are intact and reinstall on shutoff valves to prevent refrigerant leakage. Replace shutoff valve access caps and torque to the following specifications.

Torque Values

Stem 18-20 ft. lbs. (24.4-27.1 Nm)

Caps 12-15 ft. lbs. (16.3-20.3 Nm)

Schrader Core 1.5-3 in. lbs. (0.17-0.34 Nm)

Step 7 Insulation Requirements

To prevent condensation, the entire suction line must be insulated. All insulation must be airtight and sealed at both ends.

The following insulation requirements prevent condensation at 90^ F ( 32^ C) ambient 90% Relative Humidity. If higher humidity is expected, increase insulation thickness.

The entire suction line set requires:

Suction Line Liquid Line		Min. Insulation Thickness
5/8 in. (16 mm) 3/8	in. (10 mm)	3/8 in. (9 mm)Suction Line3/8 in. (9 mm)Liquid Line

Important

To prevent condensation, the entire suction line must be insulated. All insulation must be airtight and sealed at both ends.

The minimum requirements are for conditions at or below 90% humidity and 90°F (32°C) ambient. When higher humidity will be experienced, or local code requires, insulation wall thickness will need to be increased.
