Failure to properly install the bin control assembly could result in ice backup and unit damage. 1) Remove the bin control insulation and bin control cover. See Fig. 6. 2) Remove the bin control bracket, bin control bulb holder, two 4×6 screws, two lock washers, two flat washers, 3 wire ties, and two 4×8 screws from the accessory bag.
E. Installation of the Remote Condensing Unit WARNING • Installation must be performed by properly trained and EPA-certified service personnel. • Power supply and ground wire to the icemaker are supplied from the remote condensing unit. For details, see "II.F. Electrical Connection." 1. Setup 1) Secure the legs to the remote condensing unit with the 8 bolts and nuts provided. See Fig. 7. Bolt with Split Lock Washer and Flat Washer 2) The legs have 8 mounting holes.
3. Line Set Installation WARNING • R-404A itself is not flammable at atmospheric pressure and temperatures up to 176°F (80°C). • R-404A itself is not explosive or poisonous. However, when exposed to high temperatures (open flames), R-404A can be decomposed to form hydrofluoric acid and carbonyl fluoride both of which are hazardous. • Do not use silver alloy or copper alloy containing arsenic. • Do not open any service valve until the line set installation is complete and leak tested.
12) Replace the service valve caps and tighten. 13) Insulate all exposed tubing and fittings. Hoshizaki Technical Support is available at 1-800-233-1940 for recommendations.

F. Electrical Connection WARNING Icemaker • Do not connect the icemaker to an external power source. Icemaker power supply and ground connection are supplied from the remote condensing unit via the wire bundle provided with the remote condensing unit. • Wire bundle routing (conduit) and disconnect (if required) must meet national, state, and local electrical code requirements. If fabricating a wire bundle, use wire of an appropriate gage and outdoor rating.
1) Route the wire bundle between the icemaker and remote condensing unit. Use the wire bundle supplied with the remote condensing unit, or fabricate a wire bundle using wire of an appropriate gage and outdoor rating. Use the wiring label or Fig. 10 as a reference. 2a) Icemaker: Connect the wire bundle ground wire to the icemaker ground screw, then connect the rest of the wire bundle wires to the icemaker terminal block.
