FM1200R

Location

After uncrating and inspection, the uni t 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 the bin top according to the directions 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.

Ice Maker

The machine is heavy, so the use of a mechanical lift is recommended for lifting the machine high en ough 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 machine to the bin with the hardware provided with the machine.

Remove the front panel and remove any shipping blocks.

Note: Be sure to allow a 6" m in imum space above the top of the machine for service.

BUILDING

FM1200R

FOR THE INSTALLER: Remote Condenser

Location

Limited to a 40 foot or a 25 foot length of precharged refri g er ant 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 th e tubing is complete. See the coupling instructions, 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.

5. Have the roofing contractor seal the holes in the roof per local codes.

FOR THE INSTALLER: Precharged Lines

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. Begin tightening the couplings together by hand, then using two w re nc h es (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.

4. 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.

5. Connect the 3/8 inch liquid line (schrader valve end) to the remote condenser fitting marked "liquid line".

6. Connect the other end of the liquid line to the icemaker fitting marked "liquid line."

7. Connect the 1/2 inch discharge line (schrader valve end) to the remote condenser fitting marked "discharge line".

8. Connect the other end of the liquid line to the icemaker fitting marked "discharge line".

9. After all connections are made, and after the king valve has been opened, check the couplings for leaks.

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.

FOR THE ELECTRICIAN

CONFORM TO ALL APPLICABLE CODES

The electrical power to the unit is supplied through the junction box at the rear of the machine.

Check the nameplate (located on the back panel) for the voltage req ui re m e nt s , an d f or 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.

FOR THE ELECTRICIAN: Fan Relay Kit Phasing (Do After Start Up)

Only for 230 volt icemakers and 230 volt condenser.

6. Check phasing of the electrical circuit as follows:

A. The phasing of the wiring MUST now be checked, as incorrect phasing will result in a failure of the kit relay.

Below is an illustration of the KCMR230 terminal strip. Note th at ea ch te rm in al is marked: 1-2-3-4-5-6. For pro pe r ph as ing:

Terminals #1 and #3 must be connected to the same side of the line (such as L1)

Terminals #2 and #4 must be connected to the same side of the line (such as L2).

B. Make a test with a volt meter as follows:

1. Switch on icemaker #1 first, then switch on icemaker #2.

(The compressors must be ope rating for this test. Do this after start up.)

2. Test with a volt meter between terminals #2 and #4, then between terminals #1 and #3.

Compare the readi n gs obtained to the one s in the following list:

C. Test terminals 1-2 = F ul l Voltage (208-230) Test terminals 1-3 = No voltage Test terminals 2-3 = Full Voltage Test terminals 2-4 = No voltage Test terminals 3-4 = Full voltage Test terminals 1-4 = Full voltage D. If there is full voltage where there should

be no voltage, turn off icemaker #2, (both switches) Then turn off icemaker #1 (both switches). The connections at the KCMR230 terminal strip marked icemaker #1 must be reversed (put the wire that was on 1 on 2 and the wire that was on 2 on 1).
