2.1 Uncrating and Inspection

2.2 Installation

When the unit is received and while the carrier is still present, inspect the shipping carton for any damage that may have occurred in transit. If the carton is broken, torn, or punctured,

Figure 2-1 Machine bolted to Shipping Base

Figure 2-2 Installing Mounting Legs or Casters

CAUTION Be sure to properly support the machine when removing bolts and installing legs or casters.

CAUTION

All materials and connections must conform to local requirements and be in compliance with the National Electrical Code (NEC).

note the damage on the carrier’s freight bill and notify the carrier’s local agent immediately.

1. Remove the carton from the pallet, and move the machine as close as possible to the permanent location.

2. Remove the shipping bolts on the bottom of the freezer (figure 2-1) and install either the legs or casters (figure 2-

2).

NOTE: Screw

casters or legs all the way in coupling, then adjust out to level.

1. This freezer is designed for indoor use and must be protected from outdoor weather conditions.

2. Where codes permit, we recommend that the freezer be installed on casters and have flexible water and electrical connections for service and cleaning ability.

3. Air cooled models require a minimum 6 inch (15 cm) clearance on either the side panels or the rear panel for adequate ventilation. Freezers designed with top air discharge require at least 18 inches (45 cm) above the top panel be free of obstructions. Anything blocking ventilation of the freezer (including cone dispensers) will reduce the efficiency of the freezer.

CAUTION To prevent accidental electrical shock, a positive earth ground is required.

1. Always verify electrical specifications on the data plate of each freezer. Data plate specifications will always supersede the information in this manual.

CAUTION To prevent accidental electrical shock, a positive earth ground is required.

1. Check the data plate for fuse size, wire ampacity, and electrical specifications.

2. Refer to the wiring diagram provided for proper power connections.

4. Water cooled models will require a 3/8 inch MPT water inlet and water waste connection. The connections are found on the bottom under the compressor mounting area and are clearly tagged “Water Inlet” and “Water Waste.” A manual shut-off valve should be installed in the water inlet line at the time of installation. The water pressure must be between 35-140 psig (241-965 kPa) for proper operation.

5. Place the freezer in the final location and level by adjusting the legs or casters so that it is level side-to-side and the front is approximately ¼ inch (6 mm) lower than the rear to allow proper drainage of the freezing cylinder.

2. Supply voltage must be within +

10% of voltage indicated on the nameplate. Also, on three-phase systems, voltage between phases must be balanced within 2%. (More than a 6 volt difference between any two voltage measurements at 208-230 volts indicates a possible imbalance.) Request your local power company to correct any voltage problem.

3. An easily accessible main power

disconnect must be provided for all poles of the wiring to the freezer.

3. Electrical connections are made in the junction boxes located mid-level behind the left side panel.

4. Use a flexible connection when permissible. All materials and connections must conform to local codes and the National Electrical Code.

5. For 3 phase freezers, beater shaft rotation must be clockwise as viewed from the front of the freezer.

This control protects the beater motor against failure from an overload condition by automatically shutting down the freezer. To restart the freezer properly, turn the SELECTOR switch to “OFF” and wait 2-3 minutes. Then depress the red reset button and turn the SELECTOR switch back to the “AUTO” or “CLEAN” position.

When flashing, this light indicates the mix in the mix container is at a low level and should be refilled as soon as possible. Always maintain at least 2 inches (5 cm) of mix in the container. For best operating results keep container full.

For the “ADD MIX” indicator lights to work, the probes must be installed in the mix container, with cords attached and plugged

Important: If the overload trips frequently, your freezer should be checked for proper product temperature, overrun and voltage. Contact your Electro Freeze Distributor.

Important: If proper mix level is not maintained, a freeze-up may occur and cause damage to the freezer.

6.3 Cleaning Instructions

NOTE: It is your responsibility to be aware of, and conform to, the requirements for meeting all federal, state, and local laws concerning the frequency of cleaning and sanitizing the freezer.

1. Prepare a three-compartment sink for cleaning, rinsing, and sanitizing parts removed from the freezer, per applicable local health codes. Also prepare a clean surface to air-dry all parts.

Do not use unapproved sanitizer or laundry bleach. These materials may contain high concentrations of chlorine and will chemically attack freezer components.

Figure 6-5 Clean head ports and openings with brush.

CAUTION To prevent bacteria growth, remove all O-rings when cleaning. Failure to do so could create a health hazard.

 Important:

CAUTION Electrical shock hazard. Do not splash water on switches or allow water to flow onto electrical components inside the machine.

NOTE: The sanitizer should be mixed

according to the manufacturer’s instructions to yield 100PPM available chlorine solution (example: Stera-Sheen Green Label.) Use warm water (100° to 110°F or 38° to 43°C) to wash, rinse, and sanitize.

2. Wash all parts removed from the freezer thoroughly with dish detergent. Clean the following parts with the appropriate supplied brush:

a. The mix container, pickup

tube assemblies, hoses, and probes.

b. The head plunger openings, center plunger ports, O-ring grooves, dispense nozzle mounting rings, and mix ports, as shown in figure 6-5.

Correct assembly of the freezer is essential to prevent leakage of the product and damage to the freezer. To assemble the freezer you will need an approved lubricant (such as Petrol-Gel). Make sure all parts of the assemblies have been washed and sanitized before assembling. Persons assembling the freezer must first wash and sanitize their hands and forearms with an approved sanitizer. Follow these directions for each cylinder of the freezer.

CAUTION To avoid electrical shock or contact with moving parts, make sure all switches are in the “OFF” position and that the main power supply is disconnected. Some freezers have more than one disconnect switch.

1. To assemble the shaft seal, install the cup seal and O-ring on the washer (see figure 7-1). Apply a light amount of approved sanitary lubricant (such as Petrol-Gel) to the O-ring and the face of the plastic washer opposite the bell portion of the seal. Do not allow any lubricant to come into contact with the bell-shaped rubber portion of the seals.

2. Install the shaft seal over the rear of the beater shaft, with the bellshaped portion facing the rear, as shown in figure 7-2.

3. Place the scraper blades on the beater shaft, making sure the blades are installed properly (see figure 7-3).

4. Insert the assembled beater shaft into the cylinder by placing the rear blade on the bottom of the cylinder. This will center the beater and allow alignment with the drive coupling. Rotate the beater assembly while pushing, until the shank has engaged the coupling. Repeat for second cylinder assembly.
