NORMAL OPERATIONS

The microprocessor control board controls the cabinet temperature based on the input received from the cabinet temperature thermistor. The thermistor value is compared to the control board set point. When the reach-in temperature is equal or greater than the set point (plus half the differential), the compressor relay closes, provided the following conditions are satisfied:

• Power has been uninterrupted to the control board for a 3 minute period.

• The 3 minute compressor time delay has expired. The delay period starts after the compressor has run and then cycles off.

The compressor relay opens when the reach-in temperature is less than the set point (minus half the differential).

OPERATION IN THE CLEAN/SANITIZE CYCLE

During the weekly cleaning/sanitize cycle, the evaporator fan motor relay and the condenser fan motor/compressor relay remain energized.

ADAPTIVE DEFROST

After 3 hours of cumulative compressor run time, the compressor will be de-energized for fifteen (15) minutes.

HIGH TEMP ALARM

High temp alarm will display when product thermistor is above 5.5°C / 42°F for 30 minutes and the following conditions are satisfied:

• 3 hours since power is applied

• 1 hour since cleaning cycle

Error display will reset when the temperature reaches 5°C / 41°F or below.

THERMISTOR FAILURE

If the microprocessor control board receives an open or shorted cabinet thermistor signal, the following will happen:

1. A fault is displayed on the LCD screen

- Cabinet sensor open

- Cabinet sensor shorted

2. The microprocessor will initiate a default sequence for the refrigeration system - 12 minutes on, 3 minutes off.

3. The default cycle continues until the fault is corrected or power is disconnected. See “Temperature Thermistor

- Nozzle, Cabinet or Defrost” on page 125.

EVAPORATOR & CONDENSER FAN MOTOR OPERATION

The condenser fan motor and compressor share the same relay. The evaporator fan motor relay is energized continuously and the evaporator fan runs continuously.

Important

If the machine going to be shutdown for any length of time it is recommended to go through the Zone 2 Weekly Cleaning both prior to turning off the unit and when returned to use.

If the unit is turned off, the product will no longer be kept cool in the refrigeration cabinet, remove all product bags and keep refrigerated to prevent spoilage.

DOOR GASKET MAINTENANCE

Door gaskets require regular cleaning to prevent mold and mildew buildup and also to retain the elasticity of the gasket. Gasket cleaning can be done with the use of warm soapy water. Avoid full strength cleaning products on gaskets as this can cause them to become brittle and crack. Never use sharp tools or knives to scrape or clean the gasket. Gaskets can be easily replaced and do not require the use of tools or an authorized service person. The gaskets are “Dart” style and can be pulled out of the groove in the door and new gaskets can be “pressed” back into place.

DRAIN MAINTENANCE  INSIDE LOWER CABINET

Each unit has a drain located inside the unit that removes the condensation from the evaporator coil and routes it to an external condensate evaporator pan. Each drain can become loose or disconnected during normal use. If you notice water accumulation on the inside of the unit, be sure the drain tube is connected to the evaporator drain pan. If water is collecting underneath the unit, make sure the end of the drain tube is in the condensate evaporator in the machine compartment. The leveling of the unit is important as the units are designed to drain properly when level. Be sure all drain lines are free of obstructions.

Warning

Disconnect power to the unit before performing any service or maintenance functions.

Part Number 9294938 07/29/2016 25

Maintenance Section 4

REFRIGERATOR

Caution

Warning

Do not damage the refrigeration circuit when installing, maintaining or servicing the unit.

The interior and exterior can be cleaned using soap and warm water. If this isn’t sufficient, try ammonia and water or a nonabrasive liquid cleaner. When cleaning the exterior, always rub with the “grain” of the stainless steel to avoid marring the finish. Do not use an abrasive cleaner because it will scratch the stainless steel and can damage the breaker strips and gaskets.

STAINLESS STEEL CARE & CLEANING

To prevent discoloration or rust on stainless steel, several important steps need to be taken. First, we need to understand the properties of stainless steel. Stainless steel contains 70-80% iron, which will rust. It also contains 1230% chromium, which forms an invisible passive film over the steel’s surface, which acts as a shield against corrosion. As long as the protective layer is intact, the metal is still stainless. If the film is broken or contaminated, outside elements can begin to break down the steel and begin to form discoloration or rust. Proper cleaning of stainless steel requires soft cloths or plastic scouring pads.

Important

Never Use Steel Pads, Wire Brushes or Scrapers!

Never use a high-pressure water wash for this cleaning procedure as water can damage the electrical components located near or at the condenser coil.

DOORS/HINGES

Over time and with heavy use, doors and hinges may become loose. If this happens, tighten the screws that mount the hinge brackets to the frame of the unit. Loose or sagging doors can cause the hinges to pull out of the frame, which may damage both the doors and the hinges. In some cases this may require trained & qualified service agents or maintenance personnel to perform repairs.

NOTE: Do not place hot pans on/against the blue ABS liner. Do not throw items into the storage area. Failure to follow these recommendations could result in damage to the interior of the cabinet or to the blower coil. Overloading the storage area, restricting the airflow, and continuous opening and closing of the doors and drawers will hamper the unit’s ability to maintain operational temperature.

PREVENTING CORROSION

Immediately wipe up all spills.

CLEANING KITS

Cleaning solutions need to be alkaline based or nonchloride cleaners. Any cleaner containing chlorides will damage the protective film of the stainless steel. Chlorides are also commonly found in hard water, salts, and household and industrial cleaners. If cleaners containing chlorides are used, be sure to rinse repeatedly and dry thoroughly. Routine cleaning of stainless steel can be done with soap and water. Extreme stains or grease should be cleaned with a non-abrasive cleaner and plastic scrub pad. Always rub with the grain of the steel. There are stainless steel cleaners available which can restore and preserve the finish of the steel’s protective layer. Early signs of stainless steel breakdown are small pits and cracks. If this has begun, clean thoroughly and start to apply stainless steel cleaners in attempt to restore the passivity of the steel.

Caution

Never use an acid based cleaning solution! Many food products have an acidic content, which can deteriorate the finish. Be sure to clean the stainless steel surfaces of ALL food products. Common items include: tomatoes, peppers and other vegetables.

Complete cleaning kits are available (part number 000-BIC001Q). These kits include the following:

• (3) three 5 gallon buckets

• Bucket labels for Wash, Rinse, & Sanitizing

• Red & Blue Cups for blender cleaning

• Squeeze Bottle

• Dispense Area Shield

• Tubing Manifold for product line cleaning

26 Part Number 9294938 07/29/2016

Section 4 Maintenance

OTHER MONTHLY TASKS

Cleaning the Condenser Coil

In order to maintain proper refrigeration performance, the condenser fins must be cleaned of dust, dirt and grease regularly. It is recommended that this be done at least every three months. If conditions are such that the condenser is totally blocked in three months, the frequency of cleaning should be increased. Clean the condenser with a vacuum cleaner or stiff brush. If extremely dirty, a commercially available condenser cleaner may be required.

Failure to maintain a clean condenser coil can initially cause high temperatures and excessive run times. Continuous operation with a dirty or clogged condenser coil can result in compressor failure. Neglecting the condenser coil cleaning procedures will void any warranties associated with the compressor and cost to replace the compressor.

Caution

Never use a high-pressure water wash for this cleaning procedure as water can damage the electrical components located near or at the condenser coil.

BLENDER CONTROL BOARD

Location

Each blend chamber has a dedicated Blender Control Board. The Blend Chamber Assembly needs to be separated from the frame in order to access the blender control board.

Function

The Blender Control Board provides control of the blender position, up/down movement of the linear slide, and on/off motor operation. The Blender Control Board is software-driven and retains firmware which can be updated via the USB port, near the power switch on the left side of the unit.

Specifications

The Blender Control Board receives 230 VAC line voltage and 24 VDC low voltage. The blender board executes the blend profile of the customer’s recipe when a drink is selected. The board will distribute voltage to the blender motor, linear slide, or the rinse water solenoid as instructed according to the current firmware and instruction from the UI. Instruction from the UI is transmitted via Modbus communication cable connected at J4. The blender also receives input from the blender door reed switch and the blender home position switch.

Check Procedure

The Blender Control Board function can be tested via the “Outputs” in the UI service screen. (Managers Menu> Service> OUTPUTS). Operate the blender blade to verify blade operation and/or the blender slide to verify linear slide operation.

To test the motor blade it’s best to place a cup of water in the blend chamber to be tested, activate the blender slide on the side to be tested, and then activate the blender blade. This will allow for a better visual of the blade turning.

NOTE: The blender blade will only operate for 3 seconds at half voltage in this test function.

Blender Board connections:

• J5 (N) / J6 (L1) - 230 VAC

• J2 (N) / J7 (L1) - 230 VAC (Present with relay closed)

2. Refer to 24-Hour Ice Production/Refrigeration Pressure/ Temperature Chart for ice machine being checked.

Use the operating conditions determined in step 1 to find the published normal discharge pressure/temperature and compare to actual measurements.

3. Measure the actual discharge pressure/temperature.

4. Compare the measurements (step 3) with the published pressure/temperature (step 2).

Measurements will fall within the published range on normally operating ice machines.

Section 7 Component Check Procedures

COMPRESSOR DRAWING LOCKED ROTOR

To determine if the compressor is seized, check the amp draw while the compressor is trying to start.

The two likely causes of this are a defective starting component and a mechanically seized compressor.

To determine which you have:

Install high and low side gauges.

Try to start the compressor.

Watch the pressures closely.

If the pressures do not move, the compressor is seized. Replace the compressor.

If the pressures move, the compressor is turning slowly and is not seized. Check the capacitors and relay.

COMPRESSOR DRAWING HIGH AMPS The continuous amperage draw on start-up should not be

near the maximum fuse size indicated on the serial tag.

DIAGNOSING CAPACITORS

If the compressor attempts to start, or hums and trips the overload protector, check the starting components before replacing the compressor.

Visual evidence of capacitor failure can include a bulged terminal end or a ruptured membrane. Do not assume a capacitor is good if no visual evidence is present.

Use a capacitor tester when checking a suspect capacitor. Clip the bleed resistor off the capacitor terminals before testing.

If the compressor hums and will not start but the windings are good. Replace the start capacitor.

A good test is to install a known good substitute capacitor.

Filter-Driers

Location

Cabinet: between compressor and condenser coil.

Function

To remove moister and particulates from the refrigerant. This will prevent premature failure of the compressor and blocking of restrictor devices.

Specification

The size of the filter-drier is important due to a critical refrigerant charge. Using an improperly sized filter- drier will cause the refrigeration system to be improperly charged with refrigerant.

Driers are covered as a warranty part. The drier must be replaced any time the system is opened for repairs. Refer to the parts manual for the recommended OEM field replacement drier.

Check Procedure

The drier should not alter the temperature of the refrigerant. Compare the temperature of the copper pipe either side of the filter/drier, they should be the same.

If there is a temperature drop that indicates a partial blockage of the filter/drier and it should be replaced.
