Installation
Ice machine 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 cannot
meet these requirements or have questions, call our technical service group immediately at [phone] or
+1[phone].
Top mount ice machine on bin installation procedure (models MCD400A/WBT and
MFD400A/WBT)
Install ice machine and rough-in utilities
1. Install ice storage bin in its nal location.
2. Install one supplied grommet in large knockout in base of ice machine and second supplied grommet in ice
hole provided in top of ice storage bin.
3. Rough in plumbing and electrical per specications provided.
4. Flush all water lines before nal hook up.
5. Position ice machine with utility connections facing rear of bin.
§If new storage bin and ice machine – position ice machine with connections facing rear of bin.
§If using existing bin – place supplied gasket 2.5" (64 mm) from front of bin (Fig. 1). Position ice machine with utility
connections facing rear of bin.

6. Make nal plumbing and electrical connections.
7. Working from inside bin storage area, push end of transport tube without fasteners up through grommets
into ice machine, leaving about 2" (51 mm) 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 ange (no ange on MFD400 series ake ice machine).
11. Position ice tube under oat 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. 2).

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 ice machine on.
3. Remove cover on oat reservoir.
4. Push down on oat to force water out overow tube and into evaporator drain pan.
5. Check that water drains freely from evaporator drain pan.
6. Lift oat and check that oat valve shuts off incoming water when raised.
After turning power on
1. Turn power to ice machine on and conrm that gearmotor, compressor and fan motor start immediately.
2. Check that ice begins to enter bin within approximately 10 minutes.
3. With ice machine running, check that oat reservoir water level is approximately 3/8" (10mm) below internal
overow 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 ice machine
shuts down.
5. Warm ice level control stat with your ngers and check that ice machine restarts in approximately
20minutes. (Bin must be calling for ice.)
RIDE model ice machine installation procedure (models MCD400A/WHS and MCD400A/WVS)

accessory.
General requirements
§Front of ice machine free of obstructions, plumbing lines, electric conduits.
§12" (305 mm) minimum clearance above ice machine for access to ice machine components.
§6" (15.3 cm) minimum clearance between exhaust side of ice machine and adjacent equipment.
§Do NOT weld ice machine to counter channels.
§Large, removable panels in counter face to allow ice machine removal.
§Machine stand accessory required for ice machines not supported on counter channels.
Connection requirements
§Compression ttings for water and drain lines.
§Separate drains for condenser and ice machine. Do NOT connect drains.
§20A power supply with 6 feet.

Field wiring diagrams for RIDE model ice machine installations
§All eld 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 eld wiring diagram.
§MCD400A/W and R400A/W ice machines have separate power supply from dispenser.
§Electric disconnects required within 10 ft (3 m) for all hard-wired connections.
