• To prevent damage to equipment, do not operate the icemaker when the water supply is off, or if the pressure is below 7 PSIG. Do not run the icemaker until the proper water pressure is reached. • Connect to potable water supply only. Do not connect to a hot.water supply. • In areas where water damage is a concern, install in a contained area with a floor drain. • Water line installation to the icemaker is not warranted by Hoshizaki. • Water-hammer issues must be resolved by a qualified plumber before installing the icemaker. Water hammer can cause icemaker damage that may lead to water leakage or flooding. • If using the optional drain pump (HS-0248), test its operation every time the icemaker is cleaned and sanitized. See "IV.E. Optional Drain Pump" for details. If the optional drain pump is not operating properly, water could back up and overflow, leading to costly water damage. • A plumbing permit and services of a licensed plumber may be required in some areas. • External filters, strainers, or softeners may be required depending on water quality. Contact your local Hoshizaki Certified Service Representative for recommendations. • Water supply inlet is 1/2" female pipe thread (FPT). Fig. 30 Piping to approved drain. Leave a 2.inch (5-cm) vertical air gap between the end of the pipe and the drain. 2-inch (5-cm) air gap Floor Drain Water Supply Line Shut-Off Valve Water Supply Line Drain Valve Water Supply Inlet 1/2" FPT Drain Outlet 1/2" FPT Vented Tee Connection Extend the vent at least 12" (30 cm) above the drain outlet. Minimum 1/4" Nominal ID Copper Water Tubing or Equivalent Minimum 1/2" Nominal ID Hard Pipe or Equivalent Be sure there is sufficient extra water supply line and drain line for the unit to be pulled out for service. • A water supply line shut-off valve and drain valve must be installed. A minimum of 1/4" nominal ID copper water tubing or equivalent is required for the water supply line. Be sure there is sufficient extra water supply line for the unit to be pulled out for service. • Water supply pressure must be a minimum of 7 PSIG and a maximum of 113 PSIG. If the pressure exceeds 113 PSIG, the use of a pressure reducing valve is required. • Drain outlet is 1/2" FPT. A minimum of 1/2" nominal ID hard pipe or equivalent is required for the drain line. Installing a smaller diameter drain line will reduce water flow and may lead may lead to water leakage or flooding. Be sure there is sufficient extra drain line for the unit to be pulled out for service. • Drain line should not be piped directly to the sewer system. An air gap of a minimum of 2 vertical inches (5 cm) must be between the end of the drain pipe from the icemaker and the floor drain. • For gravity drain installation, drain must have 1/4" fall per foot (2 cm per 1 m) on horizontal runs to get good flow. A vented tee connection is also required for proper flow. Extend the vent at least 12" (30 cm) above the drain outlet. • For optional drain pump installation, refer to the instructions included with the pump. G. 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 storage bin. 1) Is the icemaker level? 2) Is the icemaker in a site where the ambient temperature is within 45°F to 100°F (7°C to 38°C) and the water temperature within 45°F to 90°F (7°C to 32°C) all year around? 3) Have the shipping carton, tape, and packing material been removed from the icemaker? Has the protective plastic film been removed from the panels? 4) Have all electrical and water connections been made? Do electrical and water connections meet all national, state, and local code and regulation requirements? 5) Has the power supply voltage been checked or tested against the nameplate rating? Is the power supply a properly grounded, independent 3-prong wall outlet? 6) Are the water supply and drain lines sized as specified? Are the water supply line shut-off valve and drain valve installed? Has the water supply pressure been checked to ensure a minimum of 7 PSIG and a maximum of 113 PSIG? 7) Are all components, fasteners, and thumbscrews securely in place? 8) Has the end user been given this instruction manual, and instructed on how to operate the icemaker and the importance of the recommended periodic maintenance? 9) Has the end user been given the name and telephone number of an authorized service agent? 10) Has the warranty tag been filled out and forwarded to the factory for warranty registration? 26 III. Operating Instructions A. Important Notes About Usage WARNING • Only qualified service technicians should install and service the icemaker. • Failure to install, operate, and maintain the equipment in accordance with this manual will adversely affect safety, performance, component life, and warranty coverage. • To reduce the risk of electric shock, make sure the power switch is in the "OFF" position before plugging in or unplugging th...
