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.
GEM-MFI SERIES For the Installer Allow 6 “Clearance for Air Circulation Allow 6 “Clearance for Air Circulation A proper installation locates the ice machine indoors, but in a place where the heat and noise it produces are not objectionable. Two Units on One Bin Air cooled machines discharge hot air out the back and must have a minimum of 6 inches of clearance behind the ice machine. Space for maintenance access is also important.

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.
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.

GEM-MFI SERIES For the Installer 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.
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.

Install a hand valve near the machine to control the water supply. Drains: ●Remote Cooled Models: There is one 3/4 inch FPT drain at the back of the cabinet; the drain line is of the gravity type, and 1/4 inch per foot fall is an acceptable pitch for the drain tubing.
GEM-MFI SERIES For the Electrician Electrical Connections: Check the ice machine nameplate (located on the back panel) for the voltage requirements, and minimum circuit ampacity. The ice machine requires a solid chassis to earth ground. Connect the ice machine to its own electrical circuit so it is individually fused. Voltage variation must remain within the limitations, even under starting conditions. Note: All external wiring must conform to national, state and local electrical codes.
GEM-MFI SERIES For the Electrician INSTALLATION MUST CONFORM TO ALL APPLICABLE CODES. Connect the electrical power to the unit to the wires in the junction box at the rear of the machine. Check the nameplate (located on the back panel) for the voltage requirements, and for the minimum circuit ampacity. The machine requires a solid chassis to earth ground wire. Connect the ice machine to its own electrical circuit so it is individually fused.
GEM-MFI SERIES For the Installer Completed Installation-Remote Condenser A typical installation should generally appear as illustrated below. The best place for the remote condenser is above the ice machine, although other locations are permissible.

GEM-MFI SERIES Sanitizing and Cleaning It is the USER’S RESPONSIBILITY to see that the unit is properly maintained. It is always preferable, and less costly in the long run, to avoid possible down time by keeping it clean; adjusting it as needed; and by replacing worn parts before they can cause failure. The following is a list of recommended maintenance that will help keep the machine running with a minimum of problems. Maintenance and Cleaning should be scheduled at a minimum of twice a year.
GEM-MFI SERIES Condenser Maintenance: Remote ● 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. Brush in direction of 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.
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.
GEM-MFI SERIES Service History What to Do Before Calling for Service: ●Check the water supply to the ice machine. The ice machine is designed to shut off if there is no water to it. Check the water filters if there are any. ●Check the power supply to the ice machine. Reset the breaker if it is tripped. ●If both water and power have been checked and are available, try switching the power OFF and then ON. After 2 minutes the machine should restart.
