INSTALLATION INSTRUCTIONS

You will get better service from the ice machine, longer life and greater convenience if you choose its location
with care. Select a location as close as possible to where the highest volume of ice will used.

Here are a few points to consider:

1. Select a location as close as possible to where you are going to use the most ice.

2. Allow a minimum of 6” space at sides and rear of machine for ventilation.

3. A kitchen installation is not desirable as a rule. If a kitchen installation is necessary, locate the machine as
far away from the cooking area as possible. Grease laden air will form a greasy deposit on the condenser.
This reduces the ice making efficiency and necessitates thorough cleaning quite often.

4. If you install the unit in a storeroom, be sure the room is well ventilated.

NOTE: Do not install where the ambient and incoming water temperature will drop below 50° F or rise

to over 100° F.

WARNING: If water pressure exceeds 50 pounds, a water pressure regulator should be
installed in water inlet line between water shut–off valve and strainer. Minimum incoming
water pressure required is 22 pounds.

5. Uncrate the unit by cutting the lower band on the carton and lift the carton off the unit.

6. All “I” series flakers are supplied with bin sealing gasket material. Install the gasket around the bottom
outside edge of the unit by removing the protective paper and pressing in place.

7. Uncrate the ice storage bin and set in place. Connect a drain hose to the bin and level the bin. Install any
required bin adapter(s) at this time.

8. Carefully place the flaker on the bin. Be careful not to damage the flaker gasket material.

9. Remove the flaker front panel. Position the bin thermostat in place and install the hold down screws as
shown in Figure 1.

10. The incoming water for the ice making section requires a 3/8” copper tube. Connect this water tube to the
3/8” male flare fitting on the back of the unit. Make all drain connections. Drain tubes cannot

be teed

together. See Figure 2 for location of all plumbing connections.

NOTE: For water cooled units, a separate 3/8” copper water line is required to be connected to the flare

fitting on the back of the unit marked condenser water in. A 3/8” flare connected line will have
to be provided from the fitting marked condenser water out to the drain.

A water regulating valve installed at the factory was set to maintain 290 to 310 PSI head pressure for R–404a
units. After 10 minutes of operation check the water temperature at condenser outlet and adjust to 100_F,

ill371

105_F if necessary.

11. Connect a drain hose to the condensate drain stub tube.

NOTE: All plumbing must be done in accordance with national and local codes.

12. Bring the electrical supply (20 Amp.) into the unit at the rear of the cabinet and enters the unit control box.
The power and ground connections are completed to the leads in the control box. Strain relief connections
must be made at the cabinet and at the control box.

NOTE: Make sure the proper voltage and number of wires are provided. See serial plate for proper

configuration.

NOTE: All wiring must conform to national and local codes.

1. Remove the chute from the evaporator assembly

2. Remove item 1, .50-20 x 1.25 bolt; item 2, .50 lockwasher; item 3, ice paddle, and item 4,
flaker cutter head.

3. Install item 5, nugget ice cutter head, and re-install items 1, 2, & 3

4. Re-install chute. (RTV must be used around the base of the chute.)

W ATER AND ICE CIRCUIT

The supply water enters the float chamber through a small orifice. The water level rises and lifts the float arm on
the float valve and seats the valve, shutting off the water supply when the water is at the desired level. As the
water leaves the float chamber, filling the evaporator, the float drops and allows additional water to enter refilling
the float chamber. Thus the water level is maintained automatically as the unit operates.

The water level in the evaporator shell will rise to the same level as the water in the float chamber. The water in
direct contact with the evaporator wall freezes and forms ice on the evaporator wall. As the freezing continues
the ice becomes thicker and exceeds the space between the evaporator wall and the auger. The auger rotating
at 8 RPM then chips off the ice and moves it to the surface of the shell. When the ice reaches the top surface of
the water in the shell it is pushed upward through the extruder opening into the cutter heads. From the cutter
head the ice enters the drop chute and falls into the storage bin. This action continues until the ice comes in
contact with the bin thermostat and the unit is shut down. The unit will remain off until the ice drops from the bin
thermostat through consumption or melting, at which time the unit will restart.
