Max. Air Temperature 500F 1000F Water Temperature 400F 1000F Water Pressure 20 psi 80 psi Voltage 5% +10% (Compared to the nameplate) The temperature limitations do not apply to the remote condenser. It will work between -20 degrees F, and 120 degrees F. Operating the machine outside of the limitations is misuse and can void the warranty.

Icemaker Nameplate Located On Back Panel Serial Plate Located Behind Front Panel December 1995 Page 3 FME1500R FOR THE INSTALLER LEVEL THE ASSEMBLY Location: After uncrating and inspection, the unit is ready for installation. It is important that the machine be installed in a location where it has enough space around it to be accessible for service, usually a minimum of 6 inches. Try to avoid hot, dirty and crowded locations. Be sure that the location for the machine is within the limitations described on page 3. Storage Bin: Tip the storage bin on its back, using parts of the carton to protect the exterior finish. 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, remove paper covering the bin gasket. Install bin top if required, follow the directions included with the bin top. Note: Do not push bin into position, but lift it there. Pushing a bin, especially one with ice in it, can cause damage to the legs and the leg mounts. GASKET Ice Maker: The 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, left, and right sides. Secure the machine to the bin with the hardware provided with the machine. Remove the front panel and remove the styrofoam shipping blocks from under the gearmotor, the top of the ice chute, and from between the gearmotor and the right side panel. FASTEN THE MACHINE TO THE BIN WITH THE HARDWARE SUPPLIED WITH THE ICEMAKER June 1994 Page 4 FME1500R FOR THE INSTALLER: Remote Condenser Installation Location: Limited to a 40 foot or a 25 foot length of precharged refrigerant tubing connecting the icemaker to the remote condenser. The condenser must be above or level with the icemaker. Select the best available location, protecting the 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 condenser to the roof. 2. Have an electrician connect the remote condenser fan motor to the icemaker, using the junction box at the back of the icemaker. PRECHARGED LINE ROUTING ///////////////////////////////CAUTION//////////////////////////////// Do not connect precharged tubing until all routing and forming of the tubing is complete. See the coupling instructions, next page for connecting instructions. //////////////////////////////////////////////////////////////////////////// 1. Each set of precharged refrigerant lines (either 25 foot or 40 foot) consists of a 3/8 inch 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. 2. Have the roofing contractor cut a minimum hole for the refrigerant lines of 1 3/4 inch. Check local codes, a separate hole may be required for the electrical power to the condenser. ////////////////////////////////CAUTION//////////////////////////////// DO NOT KINK OR CRIMP REFRIGERANT TUBING WHEN INSTALLING IT. ///////////////////////////////////////////////////////////////////////////// 3. Route the refrigerant lines through the roof opening. Follow straight line routing whenever possible. Any excess tubing MUST be retained within the building. 4. Spiral the excess length of pre charged tubing inside the building. Use a horizontal spiral (as illustrated) to avoid any traps in the lines. Note: spiral need not be as tight as illustrated. 5. Have the roofing contractor seal the holes in the roof per local codes. REMOTE CONDENSER LOCATE REMOTE CONDENSER ABOVE ICEMAKER SPIRAL EXCESS TUBING INSIDE BUILDING August 1993 Page 5 FME1500R FOR THE INSTALLER COUPLING INSTRUCTIONS ////////////////////////////////CAUTION////////////////////////////////// The couplings on the sets of precharged lines are self sealing when installed properly. Carefully follow the instructions: ////////////////////////////////////////////////////////////////////////////////// 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. Connect the couplings to the fittings: · The 3/8 inch liquid line (schrader valve end) to the remote condenser fitting marked "liquid line". · Connect the other end of the liquid line to the icemaker fitting marked "liquid line." · Connect the 1/2 inch discharge line (schrader valve end) to the remote condenser fitting marked "discharge line". · Connect the other end of the liquid line to the icemaker fitting marked "liquid line". 4. Begin tightening the couplings together by hand, then using two wrenches (it is important that ONLY the nut on the precharged lines be turned, the other parts of the couplings must NOT be allowed to turn or the process will tear out the diaphragms and they will be loose in the refrigeration system) tighten the coupling until it bottoms out or a definite increase in resistance is felt. SERVICE PORTS REMOTE CONDENSER 5. Using a marker or pen, mark a line lengthwise from the coupling union nut to the bulkhead. Then tighten the coupling and additional 1/4 turn. As the nut turns, the line will show when 1/4 turn is made. 6. After all connections are made, and after the king valve has been opened, check the couplings for leaks. Note: The system charge is contained in the machine's receiver. Holding charges of the same refrigerant are present in the remote condenser and pre-charged line sets. SCHRADER VALVE NO SHRADER VALVE 3/8" LIQUID LINE 1/2" DISCHARGE LINE TO REMOTE CONDENSER TO ICEMAKER June 1994 Page 6 FME1500R FOR THE PLUMBER CONFORM TO ALL APPLICABLE CODES Water Inlet The recommended water supply is cold water. Use 3/8" O.D. copper tubing, connect to the 3/8" male flare at the back of the cabinet. Install a hand valve near the machine to control the water supply. Drains There is one 3/4" 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. 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 3/4" rigid tubing. Storage Bin: A separate gravity type drain needs to be run. Insulation of this drain line is recommended.

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. The ice maker should be connected to its own electrical circuit so it would be individually fused. Voltage variation must remain within design limitations, even under starting conditions. Electrically the remote condenser fan motor is connected to the icemaker at the contactor terminals for the compressor and the fan motor operates whenever the compressor operates. Electrical connections are made at the junction box at the back of the icemaker and at the junction box on the remote condenser. The remote condenser must be wired to the icemaker in accordance with local and national electrical codes with a minimum of 18 Awg. wire with an ground bond ...
