GEM-MFI SERIES For the Installer

Installation Guidelines:

For proper operation of the Ice-O-Matic ice machine, the following installation guidelines must be followed. Failure to do so may result in loss of production capacity, premature part failures, and may void all warranties.

Ambient Operating Air Temperatures: (Not including remote condenser)

Minimum Operating Temperature: 50°F (10°C)

Maximum Operating Temperature 100°F (38°C)

Note: Ice-O-Matic ice makers and dispensers are not approved for outdoor installation.

Incoming Water Supply

Minimum incoming water temperature: 40^ F ( 4.5^ C)

Maximum incoming water temperature: 100°F (38°C)

Minimum incoming water pressure: 20 psi (1.4 bar)

Maximum incoming water pressure: 80 psi (4.1 bar)

Note: If water pressure exceeds 80 psi a water pressure regulator must be installed.

Note: It is not recommended to connect a water softener because the ice may be more wet and slushy than desired.

Water Softeners add salinity raising the freeze point resulting in "softer" ice. This results in lower ice production.

Drains

All drain lines must be installed per local codes. Flexible tubing is not recommended. Route bin drain, vented float overflow drain and water condenser drain individually to a floor drain. The use of condensate pumps for draining water is not recommended by Ice-O-Matic. Ice-O-Matic assumes no responsibility for improperly installed equipment.

Water Filtration

A water filter system should be installed with the ice machine.

Clearance Requirements

Self-contained air cooled ice machines must have a minimum of 6 inches (15cm) of clearance at the rear and sides of the ice machine for proper air circulation.

All the dispensers have automatic agitation to keep the ice from clumping. If agitation is too frequent, the Pearl Ice will be damaged and will become difficult to dispense. The Ice-O-Matic and Cornelius dispensers need to be set to 2 seconds on every 3 hours and the Lancer needs to be set to 4 seconds on, 150 seconds off.

The Ice-O-Matic and most Cornelius dispensers also have a restrictor plate at the outlet of the hopper. When used, that plate should be adjusted to be 1.5 inch open to limit the speed of the Pearl Ice flows out during dispensing.

GEM-MFI SEREIS For the Installer

Location:

Ice-O-Matic ice machines are designed to be installed indoors in a controlled environment. Install the ice machine in a location where it has enough space around it to be accessible for service. A minimum of 6 inches must be allowed at the back for air circulation on air cooled models. Try to avoid hot, dirty and crowded locations. Be sure that the location of the machine is within the environmental limitations.

Storage Bin:

Remove the bin packaging. Tip the storage bin on its back, using parts of the packaging to protect the exterior finish. Remove the skid and install the legs into the threaded holes in the bottom of the bin. Turn the leg levelers all the way in preparation for leveling later. Return the bin to the upright position. Note: Do not push the bin into position, but lift it there. Pushing a bin, especially one with ice in it, can cause damage to the bin legs and mounts. Install the appropriate bin top according to the instructions provided with the bin top.

Ice machine:

The ice machine is heavy, so the use of a mechanical lift is recommended for lifting the machine high enough to install on top of the bin. After the unit is placed on the bin, line it up so it is even with the back side. Secure the ice machine to the bin with the hardware provided with the ice machine. Remove the front panel and remove any shipping blocks or packaging material.

Proper functioning of the bin door requires the bin door, when it is opened, to be in a stable position. If the ice machine is too far forward on the bin, the opened door may not be stable, resulting in an unexpected closing of the bin door.

If the ice machine is to be mounted on a bin or dispenser other than an Ice-O-Matic, refer to the manufacturer's instructions for machine mounting. Ice-O-Matic will not be responsible for damage or injury that results from unexpected closing of the bin door as a result of the ice machine being too far forward on the bin.

Water Limitations:

An ice machine is a food manufacturing plant: it takes a raw material, water and transforms it into a food product, ice. The purity of the water is very important in obtaining pure ice and maximizing product life. This section is not intended as a complete resource for water related questions, but it does offer these general recommendations:

- Check with a water treatment specialist for a water test and recommendations regarding water filters and treatment

GEM-MFI SERIES Remote Condenser Location

Use the following for planning the placement of the remote condenser relative to the ice machine. Location Limits: Remote condenser location must not exceed ANY of the following:

• Maximum rise from the ice machine to the remote condenser is 35 physical feet.
• Maximum drop from the ice machine to the remote condenser is 15 physical feet.
  • Physical line set maximum length is 100 feet.
• Calculated line set length maximum is 150 feet.

Calculation Formula

• Drop = dd x 6.6 (dd= distance in feet)
• Rise = rd x 1.7 (rd = distance in feet)
  • Horizontal Run = hd x 1 (hd = distance in feet)
• Calculation: Drop(s) + Rise(s) + Horizontal Run = dd+rd+hd=Calculated Line Length

Configurations that do NOT meet these requirements must receive written authorization from Ice-O-Matic. This includes multipass or rack system remote condensers.

Do NOT:

• Route a line set that rises, then falls, then rises.
• Route a line set that falls, then rises, then falls.

Calculation Example 1:

The remote condenser is to be located 5 feet below the ice machine and then 20 feet away horizontally. (5 feet x 6.6=33 feet) + (20 feet) = 53 feet. This location would be acceptable.

Calculation Example 2:

The remote condenser is to be located 35 feet above the ice machine and then 100 feet away horizontally. (35 feet x 1.7=59.5 feet) + (100 feet) = 159.5 feet. 159.5 feet is greater than the 150 maximum is NOT acceptable.

Remote Condenser Located ABOVE Ice Machine hd Condenser Distance and Location Schematic

GEM-MFI SERIES For the Installer

Remote Condenser Location:

Limited to a 25 foot or a 40 foot length of precharged refrigerant tubing connecting the ice machine to the remote condenser. The remote condenser must be above or level with the ice machine. Select the best available location, protecting the remote condenser from extremes of dirt, dust and sun. Meet all applicable building codes. Usually the services of a licensed electrician are required.

Roof Attachment:

1. Install and attach the remote condenser to the roof of the building, using the methods and practices of construction that conform to the local building codes, including having a roofing contractor secure the remote condenser to the roof.
2. Have an electrician connect the remote condenser fan motor to the ice machine, using the junction box at the back of the ice machine.

Precharged Line Set Routing

CAUTION: Do not connect the precharged tubing until all routing and forming of the tubing is complete. See the coupling instructions for connecting information.

1. Each set of precharged tubing refrigerant lines consists of a 3/8 diameter liquid line and a 1/2 inch diameter discharge line. Both ends of each line have quick connect couplings, one end has a Schrader valve connection, that end goes to the condenser.

Note: The openings in the building ceiling or wall, listed in the next step, are the minimum sizes recommended for passing the refrigerant lines through.

1. Have the roofing contractor cut a minimum hole for the refrigerant lines of 1.750 inch. Check local codes, a separate hole may be required for the electrical power to the condenser.

Coupling Instructions:

Initial Connections:

1. Remove the protector caps and plugs. Wipe the seats and threaded surfaces with a clean cloth to be certain that no foreign matter remains on them.
2. Lubricate the inside of the couplings, especially the O-Rings with refrigerant oil.

3. Position the fittings on the correct connections on the remote condenser and ice machine.

4. The 1/2 inch discharge line (Schrader valve end) goes to the remote condenser fitting marked "Discharge Line"

5. The 3/8 inch liquid line (Schrader valve end) goes to the remote condenser fitting marked "Liquid Line".
6. The 1/2 inch discharge line goes to the ice machine fitting marked "Discharge Line".
7. The 3/8 inch liquid line goes to the ice machine fitting marked "Liquid Line".

Final Connections:

4a. Begin by tightening the couplings together by hand. Continue to turn the swivel nuts by hand until it is certain that the threads are properly engaged.
4b. Using two wrenches, one to rotate the swivel nut and one to hold the tubing, tighten each coupling.

It is CRITICAL that ONLY the NUT on the precharged tube be turned or the diaphragms will be torn loose by the piercing knives and be loose in the refrigeration system causing severe operational problems.

Note: As the coupling is tightened, the diaphragms in the quick connect couplings will begin to be pierced. As that happens, there will be increased resistance to tightening the swivel nut.

4c. Continue tightening the swivel until it bottoms out or a very definite increase in resistance is felt (no threads should be showing). Do NOT over tighten.

GEM-MFI SERIES For the Plumber

Water Inlet:

• Air Cooled Models: The recommended water supply is clean, cold water. Use 3/8 inch O.D. copper tubing, connect to the 3/8 inch FPT at the back of the cabinet. Install a hand valve near the machine to control the water supply.
• Water Cooled Models: A separate 3/8 inch O.D. copper line is recommended, with a separate hand valve to control it. Connect to the 3/8 inch FPT condenser inlet at the back of the cabinet. The water pressure to all lines must always be above 20 psig, and below 80 psig.
• Water Treatment: In most areas, a water filter of some type will be useful. In areas where the water is highly concentrated with minerals, the water should be tested by a water treatment specialist, and the recommendations of the specialist regarding filtration and/or treatment should be followed.

Drains:

• Air Cooled Models: Connect a rigid drain tube to the 34 FPT drain fitting at the back of the cabinet. The drain is a gravity type, and a 14 inch per foot fall is the minimum acceptable pitch for the drain. There should be a vent at the highest point of the drain line, and the ideal drain receptacle would be a trapped and vented floor drain. Use only 34 inch rigid tubing.
• Water Cooled Models: Connect a separate drain line to the 12 inch condenser drain connection at the back of the cabinet. Do not vent this drain.
• Storage Bin: Connect a separate gravity type drain line to the ice storage bin drain. Vent this drain if there is a long horizontal run from the bin to the floor drain. Insulation of this drain line is recommended.

Cleaning/Sanitizing Procedures

ICE Machine and/or Bin/Dispenser Cleaning and Sanitizing Instructions

Cleaning should be scheduled at a minimum of twice per year.

Sanitizing should be performed after each cleaning or more frequently as required.

Note: Electrical power will be ON when performing the following cleaning instructions.

The cleaning and sanitizing of any commercial ice machine are important procedures all operators need to have in their preventive maintenance protocol. While similar, these two procedures are uniquely different and accomplish different things. Cleaning or de-liming, dissolves the mineral deposits on the evaporator and removes scale, calcium and other mineral buildup. Sanitizing disinfects the machine and removes microbial growth including mold and slime.

In either case, it is important to use solutions that do not harm the ice machine. Never use cleaning or sanitizing solutions that contain Nitric Acid, Sulfuric Acid, Hydrochloric Acid, Carbolic Acid, Acetic Acid, diluted Acetic Acid or non-food-grade vinegar (concentration of acetic acid greater than 6% and does not contain enzymes created in processing) or any chlorine-based solution such as bleach, chlorine dioxide or any type of salts such as potassium chloride (potassium salts) or sodium chloride. Check the label or the manufacturer's Material Safety Data Sheet (MSDS) to be sure. These chemicals can attack the surface of the evaporator as well as other metal components causing corrosion and flaking. Reverse Osmosis (RO) water can be very acidic and can attack the evaporator and other metal in the ice machine. Because the RO process removes all minerals and metals from the water it can promote the faster growth of microbial, mold and slime. If RO water is used, Ice-O-Matic recommends the water pH is verified to be a neutral 7.0 to minimize the corrosive effects. Incorrect cleaners, sanitizers, and RO water that does not have a neutral pH could void the machine's warranty.

Cleaning

Prior to Cleaning the ice machine and/or Bin/Dispenser, perform the following:

1. Remove the ice machine front panel.

2. Turn the machine "OFF" at the ON/OFF selector switch.

3. Remove all ice in the storage bin. (Required for cleaning and/or sanitizing)

Cleaning Instructions-Ice Machine

1. Remove the cover from the water reservoir and block up the float.

2. Drain the water reservoir and freezer assembly using the drain tube attached to the freezer water inlet. Return the drain tube to its normal position and replace the end cap.

3. Add recommended amount of approved nickel safe ice machine cleaner (diluted per manufacturer's instructions) to the water trough. (Reference cleaner Manufacturer's instructions on the package)

4. Slowly pour the cleaning solution into the water reservoir until full. Wait 15 minutes, then switch the ON/OFF switch to the ON position.

5. As the ice machine begins to use water from the reservoir, continue to add more cleaning solution to maintain a full reservoir.

Sanitizing

Prior to Sanitizing the ice machine and/or Bin/Dispenser, perform the following:
1. Remove the ice machine front panel.
2. Turn the machine "OFF" at the ON/OFF selector switch.
3. Turn OFF the potable water supply to the ice machine
4. Remove all ice in the storage bin. (Required for cleaning and/or sanitizing)

Sanitizing Instructions-Ice Machine

1. Use an EPA approved food equipment sanitizer at the solution mix recommended by the sanitizer manufacturer.
2. Slowly pour the sanitizer solution into the water reservoir until full. Wait 15 minutes, then switch the ON/OFF switch to the ON position.
3. As the ice machine begins to use water from the reservoir, continue to add more sanitizing solution to maintain a full reservoir.
4. After all of the sanitizing solution has been added to the reservoir, and the reservoir is nearly empty, switch the ON/OFF switch to the "OFF" position.
5. Drain the water reservoir and freezing assembly using the drain tube attached to the to the freezer water inlet. Return the drain tube to its normal position and replace the drain plug end cap. Wash and rinse the water reservoir. During this time, wipe down all other ice machine splash areas. Inspect to insure that water transport system components are in the correct position.
6. Place the ON/OFF switch to the "ON" position and replace the front panel.
7. Continue ice making for at least 15 minutes to flush out any cleaning or sanitizing solution.
8. Remove and discard all ice in the storage bin. DO NOT USE any ice produced from the cleaning solution.

Sanitizing Instructions- Bin/ Dispenser

1. Use an EPA approved food equipment sanitizer at the solution mix recommended by the sanitizer manufacturer.
2. Sanitize the bin interior, this includes the bin door, bin walls, window track and snout area with an approved sanitizer using the directions for that sanitizer. Note: This includes the bin drain.
3. Remove and discard all ice in the storage bin. DO NOT USE any ice produced from the cleaning solution.

Common Questions

•Ice-O-Matic Ice Machine/Bin Cleaning

Cleaning or de-liming an ice machine refers to the process of removing mineral buildup and scale from the evaporator and other components. Ice-O-Matic recommends cleaning the ice machine at least every 6 months. More frequent cleaning may be needed depending on water quality and filtration system used. It is the responsibility of the operator to determine the optimal frequency for their particular environment. Cleaning will not remove microbial, mold, or slime. The machine should always be sanitized after cleaning.

GEM-MFI SERIES Condenser Maintenance: Remote

Brush in direction of fins ←→

- Clean the condenser: the condenser may appear to be clean on the surface, but it can still be clogged internally. Check with a flashlight from the front to see if light can be seen through the condenser fins.

The condenser coil must be kept clean. The condenser can be cleaned with compressed air or by using a brush.

If a brush is used, brush in the direction of the fins taking care not to bend or distort the fins. Use a soft bristle nylon brush.

If the condenser fins are bent or distorted, this

will restrict the airflow through the condenser and the fins will need to be straightened with a fin comb.

When cleaning the Condenser, check the fan blade for cleanliness and for balance. Balance is checked by spinning the blade by hand and looking for any wobble. Pull on the shaft in several directions to check the bearings of the motor.

The fins of the remote condenser require periodic cleaning.

Brush in direction of fins

At 6 month intervals the fins on the inlet side of the condenser (bottom as shown) should be brushed free of dust and dirt Brush in the direction of the fins as noted by the arrows.

Additionally look through the fins, using a flashlight if required, to insure there is no other blockage obstructing air flow between the fins.

If the air flow appears to be blocked, blow out the condenser using CO2 gas.

GEM-MFI SERIES Maintenance: Air Cooled

Clean the air cooled condenser:

Air flow on this model is from front to back, so the inside of the ice machine will have to be available to clean the air cooled condenser. Use a vacuum cleaner or coil cleaner if needed. DO NOT use a wire brush.

• Disconnect electrical power, and remove the air filter if applicable. The filter may be cleaned or replaced.
• Clean the condenser: the condenser may appear to be clean on the surface, but it can still be clogged internally. Check with a flashlight from the front to see if light can be seen through the condenser fins.
