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 blade moves 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.
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.

After the water tank has drained, replace the drain plug, water shield, overflow pipe, overflow cap, cube guide A, cube guide B, splash guard, and front insulation panel. Sanitizing Rinse 3 25) Turn the cleaning valve to the right until completely horizontal (closed). Move the control switch to the "ICE" position, then replace the front panel.
IV. Preparing the Icemaker for Periods of Non-Use NOTICE • When storing the icemaker for an extended time or in sub-freezing temperatures, follow the instructions below to prevent damage. • To prevent damage to the water pump seal, do not leave the control switch in the "WASH" position for extended periods when the water tank is empty. When the icemaker is not used for two or three days under normal conditions, it is sufficient to move the control switch to the "OFF" position.
3. On water-cooled models, remove the water from the water-cooled condenser: 1) Make sure the power supply is off, then remove the front panel and right side panel. 2) Close the condenser water supply line shut-off valve. If connected to a closed loop system, also close the condenser return line shut-off valve. 3) Open the condenser water supply line drain valve. If connected to a closed loop system, also open the condenser return line drain valve.
V. Disposal The icemaker contains refrigerant and must be disposed of in accordance with applicable national, state, and local codes and regulations. Refrigerant must be recovered by properly certified service personnel.
