G. Installation of Remote Condenser Unit WARNING • Installation of remote condenser unit must be performed by properly trained and EPA-certified service personnel. • The remote condenser unit must be installed in accordance with applicable national, state, and local codes and regulations. • Failure to install the remote condenser unit within these guidelines may adversely affect safety, performance, component life, and warranty coverage.
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. 10. 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. 12. 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. 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.
I. Startup WARNING All parts are factory-adjusted. Improper adjustments may adversely affect safety, performance, component life, and warranty coverage. NOTICE • If the icemaker is turned off, wait for at least 3 minutes before restarting the icemaker to prevent damage to the compressor. • 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.
III. Maintenance The appliance must be maintained in accordance with the instruction manual and labels provided. Consult with your local Hoshizaki Certified Service Representative about maintenance service. WARNING • Only qualified service technicians should service the appliance. • To reduce the risk of electric shock, do not touch the control switch with damp hands. • Move the control switch to the "OFF" position and turn off the power supply before servicing.
B. Cleaning and Sanitizing Instructions The icemaker must be cleaned and sanitized at least once a year. More frequent cleaning and sanitizing may be required in some water conditions. WARNING • To prevent injury to individuals and damage to the icemaker, do not use ammonia type cleaners. • Carefully follow any instructions provided with the bottles of cleaning and sanitizing solution.
Cleaning 4) Remove the front insulation panel, then slide the cube guide to the right. Remove the rubber cap and sleeve covering the overflow pipe. See Fig. 16. Unscrew the overflow pipe. After the water tank has drained, reconnect the overflow pipe. Replace the rubber cap, sleeve, cube guide, and front insulation panel. NOTICE! Make sure the O-ring is attached to the bottom of the overflow pipe and be careful not to cross thread the overflow pipe.
Sanitizing 14) To fill the water tank, turn the cleaning valve to the right until completely horizontal (closed). Move the control switch to the "ICE" position, then replace the front panel. After 3.5 min., remove the front panel, then move the control switch to the "OFF" position. 15) Remove the front insulation panel, then pour 1.7 fl. oz. (50 ml) of an 8.25% sodium hypochlorite solution (chlorine bleach) into the water tank. Replace the 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. After 3.5 min., remove the front panel, then move the control switch to the "OFF" position. 26) Turn the cleaning valve to the left until completely vertical (open). Move the control switch to the "WASH" position, then replace the front panel. After 5 min., remove the front panel, then move the control switch to the "OFF" position.
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 model only, first remove the water from the water-cooled condenser: 1) Make sure the power supply is off, then remove the front, top, and right side panels. 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 appliance 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.
