Top mount icemaker on bin installation procedure (models MCD400A/WBT and MFD400A/WBT)

Install icemaker and rough-in utilities

1.Install ice storage bin in its final location.

2.Install one supplied grommet in large knockout in base of icemaker and second supplied grommet in ice hole provided in top of ice storage bin.

3.Rough in plumbing and electrical per specs provided.

4.Flush all water lines before final hook up.

5.Position icemaker with utility connections facing rear of bin.

A.If new storage bin and icemaker – position icemaker with connections facing rear of bin.

B.If using existing bin – place supplied gasket 2.5" (64mm) from front of bin (Fig. 2). Position icemaker with utility connections facing rear of bin.

6.Make final plumbing and electrical connections.

7.Working from inside bin storage area, push end of transport tube without fasteners up through grommets into icemaker, leaving about 2" (51mm) hanging down in bin.

8.Route free end of tube to evaporator port.

9.Slip a hose clamp in free end of tube.

10.Push free end of tube on evaporator port and tighten clamp, making sure clamp is positioned on evaporator side of flange (no flange on MFD400 series flake icemaker).

11.Position ice tube under float bracket retaining tab.

12.Carefully slip ice level control stat alongside transport tube through both grommets and down into bin.

13.Run ice level control stat down through one side of cap tube fasteners attached to ice transport tube, form a 180˚ bend at end of tube and run back up through fastener (Fig. 1).

14.Adjust loop length to provide desired ice level. Loop must below end of ice transport tube.

15.Carefully bend end of cap tube to prevent it from slipping out of clamp.

Before turning power on

1.Clean and sanitize ice storage bin in accordance with cleaning procedure in ice storage bin installation information packed with ice storage bin.

2.Turn water to icemaker on.

3.Remove cover on float reservoir.

4.Push down on float to force water out overflow tube and into evaporator drain pan.

5.Check that water drains freely from evaporator drain pan.

6.Lift float and check that float valve shuts off incoming water when raised.

7

After turning power on

1.Turn power to icemaker on and confirm that gearmotor, compressor and fan motor start immediately.

2.Check that ice begins to enter bin within approximately 10 minutes.

3.With icemaker running, check that float reservoir water level is approximately 3/8" (10mm) below internal overflow and adjust to this level (raised line on side of reservoir) if necessary.

4.After making ice for 10 minutes, put ice against ice level control stat cap tube and check that icemaker shuts down.

5.Warm ice level control stat with your fingers and check that icemaker restarts in approximately 20 minutes. (Bin must be calling for ice.)

Satellite-fill icemaker installation procedure (models MCD400A/WHS and MCD400A/WVS)

Satellite-fill icemaker performance is very sensitive to the quality of installation. To ensure proper performance, ease of service and warranty coverage. it is critical that you follow the requirements detailed in this manual. If you can not meet these requirements or have questions, call our technical service group immediately at [phone] or [phone].

Installing Satellite-fill icemaker and rough-in utilities without optional slide-out accessory

12" (305mm) minimum clearance above icemaker for access to icemaker components.

6" (153mm) minimum clearance between exhaust side of icemaker and adjacent equipment. Do NOT weld icemaker to counter channels.

Large, removable panels in counter face to allow icemaker removal.

Machine stand accessory required for icemakers not supported on counter channels.

Connection requirements

Compression fittings for water and drain lines.

Separate drains for condenser and icemaker. Do NOT connect drains. 20 amp power supply with 6 feet.

Field wiring diagrams for Satellite-fill icemaker installations

All field wiring must be installed in accordance with NEC and local electrical codes.

Field wiring diagram is intended only to aid electrician or technician in understanding how equipment works.

Should local codes require a hard-wired connection and/or shielded wiring, eliminate the cord and plug(s) and follow the appropriate field wiring diagram.

MCD400A/W and R400A/W icemakers have separate power supply from dispenser. Electric disconnects required within 10 ft (3m) for all hard-wired connections.

Recommended junction box preparation of hard-wired Satellite-fill icemakers.

1.Cut plugs from supplied power cords.

2.Replace upper (power) strain relief with a cord connector.

3.Mount two 2" x 4" junction boxes using supplied holes in icemaker face.

4.Make power and bin signal connections.

Installing Satellite-fill icemaker and rough-in utilities with optional slide-out accessory

The slide-out accessory allows the icemaker to be pulled out on a track from below a counter without disconnecting utilities. A leg supports the icemaker in the full-out position. If your order did not include a slide-out accessory proceed to icemaker ventilation and exhaust.

Step 1 – Installing track accessory (Follow either A or B below for Satellite-fill icemaker)

Track must be positioned flush against inside of counter and slightly above counter access opening.

A. When icemaker stand is used (required if icemaker is not supported on counter channels)

1.Bolt vertical utility panel to slide-out track assembly with supplied 10/32 screws.

2.Secure slide-out track assembly to icemaker stand with 10/32 screws provided.

3.Position icemaker stand in desired location and adjust stand legs to proper height and level in both directions.

4.Using holes in flanged legs as template, mark floor for 12 anchoring holes to be drilled.

5.Remove stand/track assembly and drill marked holes.

6.Reposition and anchor stand to floor with 12 fasteners appropriate to floor material (not supplied).

Stand MUST be anchored to avoid tipping and possible injury when icemaker is pulled out.

B. When icemaker is supported on counter channels

1.Bolt vertical utility panel to slide-out track assembly with supplied 10/32 screws.

2.Position track assembly on counter channels (Fig. 3).

3.Using holes in track assembly as a template, mark and drill required holes in counter channels.

4.Remove track assembly on channels and drill marked holes.

5.Reposition track assembly on channels and secure using appropriate hardware (not supplied).
