WEBVTT 1 00:00:08.760 --> 00:00:13.020 The purpose of this video is to demonstrate the proper installation of Hoshizaki 2 00:00:13.020 --> 00:00:15.150 ice machines. While the KM, 3 00:00:15.150 --> 00:00:18.030 cuber and Flaker machines differ in some features, 4 00:00:18.240 --> 00:00:20.520 the installations are basically the same. 5 00:00:21.150 --> 00:00:23.430 In order to avoid problems after startup, 6 00:00:23.430 --> 00:00:27.270 it is important that you install these machines properly the first time. 7 00:00:27.840 --> 00:00:32.760 There are several things you should do before installing the icemaker. First, 8 00:00:32.880 --> 00:00:36.060 take a look at the installation site. Remember, 9 00:00:36.150 --> 00:00:40.650 these ice makers are not intended for outdoor use. For best 10 00:00:40.650 --> 00:00:44.610 results, the icemaker should not be located next to ovens, grills, 11 00:00:44.610 --> 00:00:46.650 or other high heat producing equipment. 12 00:00:47.550 --> 00:00:52.020 The location should provide a firm level foundation for the ice maker and 13 00:00:52.020 --> 00:00:52.980 storage bin. 14 00:00:53.700 --> 00:00:58.080 Check the installation site to be sure there is an adequate water supply and 15 00:00:58.080 --> 00:00:59.100 proper drainage. 16 00:00:59.820 --> 00:01:04.350 Be sure to allow for a six inch clearance at the rear sides and top of the 17 00:01:04.350 --> 00:01:08.850 machine's intended location to allow for proper air circulation and ease of 18 00:01:08.850 --> 00:01:13.710 maintenance and service. If you are installing an auger type ice maker, 19 00:01:13.890 --> 00:01:18.570 it is necessary to allow adequate clearance above the unit to allow for auger 20 00:01:18.570 --> 00:01:21.390 removal during service. Next, 21 00:01:21.420 --> 00:01:25.980 inspect the exterior of the cartons for visible damage and unpack the storage 22 00:01:25.980 --> 00:01:30.390 bin. Make sure it is the correct bin for your application. 23 00:01:31.050 --> 00:01:35.460 Attach the four adjustable legs provided to the bottom of the storage bin and 24 00:01:35.460 --> 00:01:38.100 position it in the selected permanent position. 25 00:01:38.760 --> 00:01:43.320 Then unpack the ice maker being careful to save the registration cards 26 00:01:43.320 --> 00:01:46.290 located in the pouch on the carton. Also, 27 00:01:46.380 --> 00:01:51.180 remove all packing material and tape from inside of the machine and remove the 28 00:01:51.180 --> 00:01:54.720 package containing the installation manual and accessories. 29 00:01:55.590 --> 00:02:00.270 Always refer to this manual or your hoshizaki technician's pocket guide 30 00:02:00.510 --> 00:02:05.100 and carefully follow the instructions for installing the ice maker. To 31 00:02:05.100 --> 00:02:09.270 prevent damage, remove the outer panels before installing the ice maker. 32 00:02:09.750 --> 00:02:14.400 Now check to see that the refrigerant lines do not rub or touch other lines or 33 00:02:14.400 --> 00:02:19.350 surfaces. On aircooled units, be sure that the fan blade turns freely. 34 00:02:20.220 --> 00:02:25.050 Check that the compressor is snug on all mounting pads. Finally, 35 00:02:25.110 --> 00:02:29.250 check the name plate to make sure that your electrical service is the same as 36 00:02:29.250 --> 00:02:30.690 the voltage specified. 37 00:02:31.230 --> 00:02:36.060 The gasket provided with hoshizaki bins provides an adequate seal between the 38 00:02:36.060 --> 00:02:36.960 two units. 39 00:02:37.740 --> 00:02:42.630 Place the ice maker on the top of the storage bin and secure it by using 40 00:02:42.630 --> 00:02:45.630 the two mounting brackets and four bolts provided. 41 00:02:46.560 --> 00:02:50.940 Level the ice maker storage bin in both the left to right and front to rear 42 00:02:50.940 --> 00:02:53.970 directions using the adjustable bin legs. 43 00:02:54.540 --> 00:02:57.540 If you are stacking two S units on a single bin, 44 00:02:57.780 --> 00:03:02.740 remove the top panel and ABS evaporator cover from the lower unit. 45 00:03:03.550 --> 00:03:08.140 Set the second unit on top and secure it with the brackets provided in the 46 00:03:08.140 --> 00:03:09.460 accessory package. 47 00:03:10.390 --> 00:03:15.070 Remove the bin control holder and bulb from the top bracket and route it to the 48 00:03:15.070 --> 00:03:20.050 bottom unit bracket. Taking care not to touch the suction or discharge lines or 49 00:03:20.050 --> 00:03:23.050 the compressor base with the control capillary tube. 50 00:03:23.890 --> 00:03:27.520 Use the top bulb holder to secure it to the bottom bracket. 51 00:03:28.210 --> 00:03:32.950 Plug in both bin control plugs and be aware that hoshizaki stacked units 52 00:03:32.950 --> 00:03:37.870 operate independently of each other. When making the electrical connections, 53 00:03:37.870 --> 00:03:41.530 it is important that they be made in accordance with the instructions on the 54 00:03:41.530 --> 00:03:44.950 warning tag provided with the leads in the junction box. 55 00:03:45.550 --> 00:03:49.900 Make sure the white leads are connected to the neutral conductor of the power 56 00:03:49.900 --> 00:03:54.640 source. To prevent possible electric shock or damage to the machine, 57 00:03:54.850 --> 00:03:59.620 be sure to install a proper ground wire to the ice maker. On 58 00:03:59.620 --> 00:04:02.830 208/230v single phase applications, 59 00:04:02.890 --> 00:04:07.300 a dedicated neutral wire is required by national electrical codes. 60 00:04:07.810 --> 00:04:12.340 A separate power supply or receptacle is required for the installation of each 61 00:04:12.340 --> 00:04:13.210 icemaker. 62 00:04:13.690 --> 00:04:18.490 Be sure to check the name plate for proper capacity. On units requiring the 63 00:04:18.490 --> 00:04:23.020 installation of a remote condenser, the unit must be installed in a permanent 64 00:04:23.020 --> 00:04:23.853 location. 65 00:04:24.340 --> 00:04:28.750 If the condenser unit supplied is not the appropriate hoshizaki condenser, 66 00:04:29.020 --> 00:04:33.310 be sure that the application has been approved in writing by the Hoshizaki 67 00:04:33.310 --> 00:04:34.930 Technical Support Department. 68 00:04:35.800 --> 00:04:38.560 The installation site should be firm and flat. 69 00:04:38.830 --> 00:04:42.310 The location should also be reasonably dry and well ventilated. 70 00:04:42.700 --> 00:04:47.590 This means locating the unit away from standing water and providing a 24 inch 71 00:04:47.590 --> 00:04:51.700 clearance on both the front and rear of the unit. Also, 72 00:04:51.700 --> 00:04:53.230 when locating the condenser, 73 00:04:53.230 --> 00:04:57.580 keep in mind that the maximum refrigerant line length with a factory charge is 74 00:04:57.580 --> 00:04:58.630 66 feet. 75 00:04:59.260 --> 00:05:03.550 This can be extended to a maximum of 100 feet with an additional charge. 76 00:05:03.880 --> 00:05:08.230 Consult the manual for recommendations for line size and charge amounts. 77 00:05:08.890 --> 00:05:11.830 To install the remote condenser unit first, 78 00:05:11.920 --> 00:05:16.420 remove it from the carton and secure the leg squarely with eight M8 by 79 00:05:16.420 --> 00:05:21.130 16 millimeter hexagon bolts and M8 nuts. Next, 80 00:05:21.190 --> 00:05:25.930 secure the legs to the roof curb with eight bolts in the eight mounting holes. 81 00:05:26.680 --> 00:05:31.360 When installing two remote condenser units, you may stack them to save space. 82 00:05:32.050 --> 00:05:36.550 Attach the upper condenser unit on top of the lower unit and secure it with the 83 00:05:36.550 --> 00:05:38.140 four screws provided. 84 00:05:39.100 --> 00:05:43.180 When installing two copper tubing sets between the ice makers and condenser 85 00:05:43.180 --> 00:05:47.890 units take extra care to mark the refrigerant lines and electrical connections. 86 00:05:48.280 --> 00:05:51.730 This will assure that they do not get crossed during installation. 87 00:05:52.540 --> 00:05:56.800 Each copper tubing should be sized properly and insulated separately. 88 00:05:57.200 --> 00:06:01.550 Pre-charged tubing kits are available from Hoshizaki America in 89 00:06:01.550 --> 00:06:04.820 20, 35 and 55 foot lengths. 90 00:06:05.180 --> 00:06:09.950 Line sets fabricated on the job should be evacuated through the charging ports 91 00:06:09.950 --> 00:06:14.510 on the Aeroquip couplings and charged with refrigerant vapor to a pressure of 92 00:06:14.510 --> 00:06:19.490 15 to 30 PSIG. Pre-charged tubing Kits do not need to 93 00:06:19.490 --> 00:06:20.480 be evacuated. 94 00:06:21.080 --> 00:06:25.700 To connect line sets to the condenser and ice making units, remove the 95 00:06:25.700 --> 00:06:30.440 plastic caps that protect the couplings and place a small amount of clean dry 96 00:06:30.440 --> 00:06:35.090 refrigerant oil on the O rings and male threads of each connection. 97 00:06:35.870 --> 00:06:39.440 Connect the refrigerant lines equipped with the proper size arrow equipped 98 00:06:39.440 --> 00:06:42.950 fittings to the connection of the condenser unit and ice maker. 99 00:06:43.400 --> 00:06:48.170 Then tighten the fittings until they bottom out and turn them one quarter round 100 00:06:48.170 --> 00:06:52.400 more. This provides a leak-free brass to brass seal. 101 00:06:53.000 --> 00:06:57.890 The van control wiring from the ice making unit requires a three wire circuit. 102 00:06:58.430 --> 00:07:00.500 To connect this circuit first, 103 00:07:00.620 --> 00:07:04.850 remove the louver panel and junction box cover from the condenser unit. 104 00:07:05.390 --> 00:07:08.720 This circuit should be routed through seal tight conduit. 105 00:07:09.290 --> 00:07:12.140 A disconnect may be required by local code. 106 00:07:13.520 --> 00:07:17.990 Connect the fan motor leads in the junction box of the remote condenser unit to the fan 107 00:07:17.990 --> 00:07:20.810 motor leads in the junction box of the icemaker. 108 00:07:21.380 --> 00:07:25.880 A proper ground wire is required to prevent possible electrical shock. 109 00:07:27.200 --> 00:07:32.030 The Icemaker inlet line must be sized correctly for proper operation. 110 00:07:32.510 --> 00:07:37.130 Check your manual carefully to be sure which size is required for the ice maker 111 00:07:37.130 --> 00:07:41.210 you are installing. Depending upon the local water quality, 112 00:07:41.330 --> 00:07:45.440 the installation of an external filter with an adequate flow rate may be 113 00:07:45.440 --> 00:07:47.540 required for the ice making inlet. 114 00:07:48.590 --> 00:07:53.540 The water supply pressure should be a minimum of 10 PSIG and a maximum 115 00:07:53.540 --> 00:07:55.910 of 113 PSIG. 116 00:07:56.750 --> 00:08:00.110 If the pressure exceeds 113 PSIG, 117 00:08:00.170 --> 00:08:05.090 you will need to install a pressure reducing valve on water cooled 118 00:08:05.090 --> 00:08:08.540 models. Two separate water supply inlets are provided, 119 00:08:08.960 --> 00:08:13.490 one for the ice making inlet and the other for the water cooled condenser inlet. 120 00:08:14.240 --> 00:08:18.560 The drain outlet for the ice maker reservoirs uses a three quarter inch female 121 00:08:18.560 --> 00:08:21.080 pipe thread or FPT. 122 00:08:21.770 --> 00:08:25.940 The drain for condensation is a three eight inch ID pipe. 123 00:08:27.110 --> 00:08:31.670 Be sure the icemaker drain and the condenser drain piping connections are made 124 00:08:31.670 --> 00:08:36.650 separately from the bend drain. Hard piping with copper or PVC 125 00:08:36.650 --> 00:08:41.270 is recommended. On water cooled models, a separate one half inch 126 00:08:41.270 --> 00:08:45.320 FPT connection is provided for the condenser drain outlet. 127 00:08:46.130 --> 00:08:50.810 All hoshizaki ice makers should be installed in accordance with all applicable 128 00:08:50.810 --> 00:08:54.800 national, state and local regulations. Also, 129 00:08:54.860 --> 00:08:58.470 a backflow preventer may be required by local codes. 130 00:08:59.310 --> 00:09:02.730 Now that you have installed the Hoshizaki Ice Maker review, 131 00:09:02.730 --> 00:09:07.470 the final checklist provided in the installation manual.
