The purpose of this video is to demonstrate the  proper installation of Hoshizaki ice machines.  

While the KM Cuber and Flaker machines differ in  some features, the installations are basically the  

same. In order to avoid problems after startup,  it is important that you install these machines  

properly the first time. There are several things  you should do before installing the ice maker.  

First, take a look at the installation site.  Remember these ice makers are not intended for  

outdoor use. For best results, the ice maker should  not be located next to ovens, grills, or other  

high heat producing equipment. The location should  provide a firm level foundation for the ice maker  

and storage bin. Check the installation site to be  sure there is an adequate water supply and proper  

drainage. Be sure to allow for a six-inch clearance  at the rear, sides, and top of the machines intended  

location to allow for proper air circulation,  and ease of maintenance and service. If you are  

installing an auger type ice maker, it is necessary  to allow adequate clearance above the unit  

to allow for auger removal during service. Next,  inspect the exterior of the cartons for visible  

damage and unpack the storage bin. Make sure it is  the correct bin for your application. Attach the  

four adjustable legs provided to the bottom of  the storage bin and position it in the selected  

permanent position. Then unpack the ice maker being  careful to save the registration cards located in  

the pouch on the carton. Also, remove all packing  material and tape from inside of the machine  

and remove the package containing the installation  manual and accessories. Always refer to this manual  

or your Hoshizaki technicians pocket guide and  carefully follow the instructions for installing  

the ice maker. To prevent damage, remove the outer  panels before installing the ice maker. Now check  

to see that the refrigerant lines do not rub or  touch other lines or surfaces. On air-cooled units,  

be sure that the fan blade turns freely. Check  that the compressor is snug on all mounting  

pads. Finally, check the nameplate to make sure that  your electrical service is the same as the voltage  

specified. The gasket provided with Hoshizaki bins  provides an adequate seal between the two units.  

Place the ice maker on the top of the storage bin  and secure it by using the two mounting brackets  

and four bolts provided. Level the ice maker storage  bin in both the left to right and front-to-rear  

directions using the adjustable bin legs. If  you are stacking two S units on a single bin,  

remove the top panel and ABS evaporator cover  from the lower unit. Set the second unit on top  

and secure it with the brackets provided in the  accessory package. Remove the bin control holder  

and bulb from the top bracket and route it to the  bottom unit bracket taking care not to touch the  

suction or discharge lines or the compressor  base with the control capillary tube. Use the  

top bulb holder to secure it to the bottom bracket. Plug in both bin control plugs and be aware that  

Hoshizaki stacked units operate independently of  each other. When making the electrical connections,  

it is important that they be made in accordance  with the instructions on the warning tag provided,  

with the leads in the junction box. Make sure the  white leads are connected to the neutral conductor  

of the power source. To prevent possible electric  shock or damage to the machine, be sure to install  

a proper ground wire to the ice maker. On 208/230 volt single-phase applications, a dedicated neutral  

wire is required by national electrical codes. A  separate power supply or receptacle is required  

for the installation of each ice maker. Be sure  to check the nameplate for proper capacity. On  

units requiring the installation of a remote  condenser the unit must be installed in a  

permanent location. If the condenser unit supplied  is not the appropriate Hoshizaki condenser, be sure  

that the application has been approved in  writing by the Hoshizaki technical support  

department. The installation site should be firm  and flat, the location should also be reasonably  

dry and well-ventilated. This means locating the  unit away from standing water and providing a  

keep in mind that the maximum refrigerant line  length with a factory charge is 66 feet. This  

can be extended to a maximum of 100 feet with  an additional charge. Consult the manual for  

recommendations for line size and charge amounts.  To install the remote condenser unit, first remove  

it from the carton and secure the leg squarely  with eight M8 by 16 millimeter hexagon bolts and M8  

nuts. Next, secure the legs to the roof curb with  eight bolts in the eight mounting holes. When installing  

two remote condenser units, you may stack them  to save space. Attach the upper condenser unit  

on top of the lower unit and secure it with the  four screws provided. When installing two copper  

tubing sets between the ice makers and condenser  units, take extra care to mark the refrigerant  

lines and electrical connections. This will assure  that they do not get crossed during installation.  

Each copper tubing should be sized properly and  insulated separately. Precharged tubing kits are  

available from Hoshizaki America in 20, 35, and  55-foot lengths. Line sets fabricated on the job  

should be evacuated through the charging ports  on the Aeroquip couplings and charged with  

a refrigerant vapor to a pressure of 15 to 30  PSIG. Precharged tubing kits do not need to be  

evacuated. To connect line sets to the condenser  and ice making units, remove the plastic caps that  

protect the couplings and place a small amount of  clean dry refrigerant oil on the O-rings and male  

threads of each connection. Connect the refrigerant  lines equipped with the proper size Aeroquip  

fittings to the connection of the condenser unit  and ice maker. Then tighten the fittings until they  

bottom out and turn them one quarter round more. This  provides a leak-free brass to brass seal. The fan  

control wiring from the ice making unit requires  a three wire circuit. To connect this circuit, first  

remove the louver panel and junction box cover  from the condenser unit. This circuit should be  

routed through seal-tight conduit. A disconnect may  be required by local code. Connect the fan motor  

leads in the junction box of the remote condenser  unit to the fan motor leads in the junction box  

of the ice maker. A proper ground wire is required  to prevent possible electrical shock. The ice maker  

inlet water line must be sized correctly for  proper operation. Check your manual carefully  

to be sure which size is required for the ice maker  you are installing. Depending upon the local water  

quality the installation of an external filter  with an adequate flow rate may be required for  

the ice making inlet. The water supply pressure  should be a minimum of 10 PSIG and a maximum  

of 113 PSIG. If the pressure exceeds 113 PSIG,  you will need to install a pressure reducing  

valve. On water-cooled models, two separate water  supply inlets are provided, one for the ice making  

inlet, and the other for the water-cooled condenser  inlet. The drain outlet for the ice maker reservoirs  

uses a 3/4 inch female pipe thread or  FPT. The drain for condensation is a 3/8 inch ID  

pipe. Be sure the ice maker drain and the condenser  drain piping connections are made separately from  

the bin drain. Hard piping with copper or PVC is  recommended. On water-cooled models a separate 1/2  

inch FPT connection is provided for the condenser  drain outlet. All Hoshizaki ice makers should be  

installed in accordance with all applicable  national, state, and local regulations. Also, a  

backflow preventer may be required by local  codes. Now that you have installed the Hoshizaki  

ice maker, review the final checklist provided in  the installation manual. At the point that the list  

requires you to start the ice machine, flush the  water system thoroughly and check the unit for  

proper operation. Check the bin control switch  for correct operation and position. This can be  

accomplished by holding an ice cube in contact  with the bulb while the ice maker is running. The  

machine should stop within six to ten seconds.  Once the installation is complete, carefully  

score the edges of the protective plastic film  and peel the film from the exterior panels. Make  

sure to give the end user the instruction  manual and review the operation of the ice  

maker, stressing the importance of performing the  recommended periodic maintenance. Also, be sure to  

give the end user the name and phone number  of an authorized service agent. Remind them  

to fill out the warranty tag and forward it to  the factory for warranty registration. Once you  

have successfully completed the checklist you can  be sure that the Hoshizaki ice maker is installed  

correctly and will avoid the unnecessary problems  that sometimes occur due to improper installation.  

Remember, while this video has shown you the proper  installation procedures, you should always refer to  

the ice maker manual or your Hoshizaki technicians  pocket guide for detailed installation information.
