2. Checks Before Installation 1) Remove the shipping carton, tape, and packing material. 2) Check that the refrigerant lines do not rub or touch lines or other surfaces, and that the fan blades move freely. 3. Setup 1) Assemble 2 sets of legs using the legs, bolts, and nuts provided. See Fig. 9. 2) Position 1 of the plates provided between a set of legs and the remote condenser unit, then secure the legs to the remote condenser unit with the bolts and nuts provided.
4. Line Set Size and Refrigerant Charge NOTICE The icemaker, line set, and remote condenser unit must contain the same type of refrigerant. Mixing of refrigerants will result in improper operation and possible damage to the refrigeration system.

5. Line Set Installation Precharged factory line sets, available as optional equipment from Hoshizaki America, are recommended. For details, see "II.G.5.a) Factory Line Set Installation." Field fabricated line sets are allowed. For details, see "II.G.5.b) Field Fabricated Line Set Installation." a) Factory Line Set Installation 1) Route the factory line set (see "II.G.4 Line Set Size and Refrigerant Charge" for details) from the remote condenser unit to the icemaker.
(1) Factory Line Set Modification 1) Recover the line set charge through the Schrader access ports on the Parker quick connect couplings and store it in an approved container. Do not discharge the refrigerant into the atmosphere. Remove the extra line set length or add extra tubing. When adding extra tubing, insulate the additional copper tubes separately. 2) Use an electronic leak detector or soap bubbles to check for leaks.
7) Connect the refrigerant lines to the appropriate male fittings on the remote condenser unit first and then at the icemaker. Make a proper connection as follows: a. Remove the protective covers from the male fitting and female coupling. b. Apply Polyol Ester (POE) refrigerant oil or Parker Super O Lube to the entire male fitting, including O‑ring, diaphragm, and threads, before making the connection. See Fig. 11. NOTICE! Do not use thread sealant on the fittings.
6. Electrical Connection WARNING • Electrical connection must meet national, state, and local electrical code requirements. Failure to meet these code requirements could result in death, electric shock, serious injury, fire, or damage. • To reduce the risk of electric shock, make all remote condenser unit connections before connecting the icemaker power supply. • THE REMOTE CONDENSER UNIT MUST BE GROUNDED.
3) Install a ground wire from the icemaker fan motor junction box to the remote condenser unit junction box. Use wire of an appropriate gage and outdoor rating. 4) Install line and neutral wires from the fan motor leads in the icemaker fan motor junction box to the leads in the remote condenser unit junction box. Use wire of an appropriate gage and outdoor rating. 5) Replace the junction box covers and the louver panel in their correct positions. 7.
H. Parallel Rack System Connection WARNING • Installation must be performed by properly trained and EPA-certified service personnel. • Failure to install the appliance within these guidelines may adversely affect safety, performance, component life, and warranty coverage. • Connect the line set to the rack system per the rack system manufacturer's instructions. NOTICE • The icemaker is shipped with a nitrogen holding charge.
3) Install Parker quick connect couplings on the icemaker end of the line set. OS-QUICK, a universal quick connect coupling kit, is required. NOTICE! Before brazing, remove the Schrader valve core from the access port. When brazing, protect the coupling by using a wet cloth to prevent the coupling from overheating. Do not use silver alloy or copper alloy containing arsenic. Braze all fittings while purging with nitrogen gas flowing at a pressure of 3 to 4 PSIG.

I. Final Checklist WARNING CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are securely in place after installation. Make sure that none have fallen into the dispenser unit/ice storage bin.
J. Startup WARNING All parts are factory-adjusted. Improper adjustments may adversely affect safety, performance, component life, and warranty coverage. NOTICE • If the appliance is turned off, wait for at least 3 minutes before restarting the appliance to prevent damage to the compressor. • At startup, confirm that all internal and external connections are free of leaks.
K. Bin Control Check An infrared sensor controls the level of ice in the dispenser unit/ice storage bin. IMPORTANT • Make sure the icemaker has been installed as outlined in this manual and that the water supply is on. • Make sure S1 Dip Switch 7 is in the "ON" position. This allows the control board to monitor the infrared sensor. 1. Infrared Sensor Check 1) Turn off the power supply. 2) Remove the front panel, top panel, and control box cover.
7) "GM" LED and "COMP" LED are on. Use an object to cover the infrared sensor lens at the bottom of the icemaker. If the bottom of the icemaker is not accessible in your application, remove the thumbscrew securing the infrared sensor housing, remove the housing from the base, then cover the infrared sensor lens. See Fig. 19. The yellow LED on the infrared sensor turns on. The yellow LED flashes when ice is at the outer limit of its range and turns steady as ice nears.
2. Infrared Sensor Shutdown Delay This is the delay between the infrared sensor detecting ice and the start of the shutdown sequence. The infrared sensor shutdown delay is factory-adjusted to 100 seconds and no adjustment is required for most dispenser unit/ice storage bin applications. a) Standard Ice Storage Bin: When installed on a standard ice storage bin, any shutdown delay setting is acceptable. b) Dispenser Unit: For typical dispenser unit applications, a 100-second shutdown delay is recommended.
L. Alarm Safeties Should an alarm occur, follow the instructions in the table below to address the alarm. If an alarm continues to occur, contact an authorized service agent. WARNING • Only qualified service technicians should service the appliance. • To reduce the risk of electric shock, do not touch the icemaker power switch or control switch with damp hands. • Before Servicing: Move the icemaker's power switch to the "OFF" position. Turn off the power supply.
