Self-Contained Air-Cooled 8" (20.3 cm) 5" (12.7 cm) Water-Cooled and Remote* 8" (20.3 cm) 5" (12.7 cm) Ice machines, like other refrigeration equipment, reject heat through the condenser. It is helpful to know the amount of heat rejected by the ice machine when sizing air conditioning equipment where self-contained aircooled ice machines are installed. Self-Contained Air-Cooled 12" (30.5 cm) 5" (12.7 cm) Water-Cooled and Remote* 8" (20.3 cm) 5" (12.7 cm) This information is also necessary when evaluating the benefits of using water-cooled or remote condensers to reduce air conditioning loads. The amount of heat added to an air conditioned environment by an ice machine using a water-cooled or remote condenser is negligible. Self-Contained Air-Cooled 8" (20.3 cm) 12" (30.5 cm) 5" (12.7 cm) Water-Cooled and Remote* 8" (20.3 cm) 8" (20.3 cm) 5" (12.7 cm) Self-Contained Air-Cooled 24" (61.0 cm) 12" (30.5 cm) Water-Cooled and Remote* 8" (20.3 cm) 5" (12.7 cm) Knowing the amount of heat rejected is also important when sizing a cooling tower for a water-cooled condenser. Use the peak figure for sizing the cooling tower. *There is no minimum clearance required for water-cooled or remote ice machines. This value is recommended for efficient operation and servicing only. ! Caution The ice machine must be protected if it will be subjected to temperatures below 32°F (0°C). Failure caused by exposure to freezing temperatures is not covered by the warranty. See “Removal from Service/Winterization”. Part Number 80-1620-3 2-7 Installation Instructions Section 2 Removing Drain Plug and Leveling the Ice Storage Bin 1. Remove threaded plug from drain fitting. 2. Screw the leveling legs onto the bottom of the bin. 3. Screw the foot of each leg in as far as possible. ! Caution The legs must be screwed in tightly to prevent them from bending. Air-Cooled Baffle SELF-CONTAINED AIR-COOLED ONLY The air-cooled baffle prevents condenser air from recirculating. To install: 1. Remove the back panel screws next to the condenser. 2. Align the mounting holes in the air baffle with the screw holes and reinstall the screws. 4. Move the bin into its final position. 5. Level the bin to assure that the bin door closes and seals properly. Use a level on top of the bin. Turn the base of each foot as necessary to level the bin. 6. Inspect bin gasket prior to ice machine installation. (Manitowoc bins come with a closed cell foam gasket installed along the top surface of the bin.) AIR BAFFLE 7. Remove all panels from ice machine before lifting. Remove both front panels, top cover, left and right side panels. SCREWS 8. Install ice machine on bin. THREAD LEVELING LEG INTO BASE OF CABINET SV1607 Air Baffle SV1606 Leveling Leg and Foot 2-8 Part Number 80-1620-3 Section 2 Installation Instructions Electrical Service Important GENERAL Observe correct polarity of incoming line voltage. ! Warning All wiring must conform to local, state and national codes. Incorrect polarity can lead to erratic ice machine operation and a safety issue. This is especially critical on 230 volt / 50 cycle ice machines. Fuse/Circuit Breaker VOLTAGE The maximum allowable voltage variation is ±10% of the rated voltage at ice machine start-up (when the electrical load is highest). A separate fuse/circuit breaker must be provided for each ice machine. Circuit breakers must be H.A.C.R. rated (does not apply in Canada). MINIMUM CIRCUIT AMPACITY ! Warning The ice machine must be grounded in accordance with national and local electrical codes. All electrical work, including wire routing and grounding, must conform to local, state and national electrical codes. The following precautions must be observed: • The ice machine must be grounded. • A separate fuse/circuit breaker must be provided for each ice machine. • A qualified electrician must determine proper wire size dependent upon location, materials used and length of run (minimum circuit ampacity can be used to help select the wire size). • The maximum allowable voltage variation is +/-10 of the rated voltage at ice machine start-up (when the electrical load is highest). • Check all green ground screws in the control box and verify they are tight before starting the ice machine. Part Number 80-1620-3 The minimum circuit ampacity is used to help select the wire size of the electrical supply. (Minimum circuit ampacity is not the ice machine’s running amp load.) The wire size (or gauge) is also dependent upon location, materials used, length of run, etc., so it must be determined by a qualified electrician.

Part Number 80-1620-3 Section 2 Installation Instructions Water Supply and Drain Requirements DRAIN CONNECTIONS WATER SUPPLY Follow these guidelines when installing drain lines to prevent drain water from flowing back into the ice machine and storage bin: Local water conditions may require treatment of the water to inhibit scale formation, filter sediment, and remove chlorine odor and taste. Important If you are installing a Manitowoc Arctic Puref water filter system, refer to the Installation Instructions supplied with the filter system for ice making water inlet connections. • Drain lines must have a 1.5 inch drop per 5 feet of run (2.5 cm per meter), and must not create traps. • The floor drain must be large enough to accommodate drainage from all drains. • Run separate bin and ice machine drain lines. Insulate them to prevent condensation. • Vent the bin and ice machine drain to the atmosphere. Do not vent the condenser drain on water-cooled models. WATER INLET LINES Follow these guidelines to install water inlet lines: • • Do not connect the ice machine to a hot water supply. Be sure all hot water restrictors installed for other equipment are working. (Check valves on sink faucets, dishwashers, etc.) If water pressure exceeds the maximum recommended pressure (80 psi), obtain a water pressure regulator from your Manitowoc distributor. Cooling Tower Applications (Water-Cooled Models) A water cooling tower installation does not require modification of the ice machine. The water regulator valve for the condenser continues to control the refrigeration discharge pressure. • Install a water shut-off valve for both the ice making and condenser water lines. It is necessary to know the amount of heat rejection, and the pressure drop through the condenser and water valves (inlet and outlet) when using a cooling tower on an ice machine. • Insulate water inlet lines to prevent condensation. • Water entering the condenser must not exceed 90°F (32.2°C). • Water flow through the condenser must not exceed 5 gallons (19 liters) per minute. • Allow for a pressure drop of 7 psi (48 kPA) between the condenser water inlet and the outlet of the ice machine. • Water exiting the condenser must not exceed 110°F (43.3°C). ! Caution Do not apply heat to water valve inlet fitting. This will damage plastic valve body.

First, cut a 2.5" (6.35 cm) circular hole in the wall or roof for tubing routing. The line set end with the 90° bend will connect to the ice machine. The straight end will connect to the remote condenser. Remote condenser installations consist of vertical and horizontal line sets between the ice machine and the condenser. When combined, they must fit within approved specifications. The following guidelines, drawings and calculation methods must be followed to verify a proper remote condenser installation. ! Caution The 60 month compressor warranty (including the 36 month labor replacement warranty) will not apply if the remote ice machine is not installed according to specifications. This warranty also will not apply if the refrigeration system is modified with a condenser, heat reclaim device, or other parts or assemblies not manufactured by Manitowoc Ice, Inc., unless specifically approved in writing by Manitowoc Ice, Inc. Follow these guidelines when routing the refrigerant lines. This will help insure proper performance and service accessibility. 1. Optional - Make the service loop in the line sets (as shown below). This permits easy access to the ice machine for cleaning and service. Do not use hard rigid copper at this location. 2. Required - Do not form traps in the refrigeration lines (except the service loop). Refrigerant oil must be free to drain toward the ice machine or the condenser. Route excess tubing in a supported downward horizontal spiral (as shown below). Do not coil tubing vertically. 3. Required - Keep outdoor refrigerant line runs as short as possible. 3 DOWNWARD HORIZONTAL SPIRAL 2 2 3 1 1 SV1204 Routing Line Sets 2-16 Part Number 80-1620-3 Section 2 Installation Instructions Make the following calculations to make sure the line set layout is within specifications. CALCULATING REMOTE CONDENSER INSTALLATION DISTANCES Line Set Length 1. Insert the measured rise into the formula below. Multiply by 1.7 to get the calculated rise. (Example: A condenser located 10 feet above the ice machine has a calculated rise of 17 feet.) The maximum length is 100' (30.5 m). The ice machine compressor must have the proper oil return. The receiver is designed to hold a charge sufficient to operate the ice machine in ambient temperatures between -20°F (-29°C) and 120°F (49°C), with line set lengths of up to 100' (30.5 m). 2. Insert the measured drop into the formula below. Multiply by 6.6 to get the calculated drop. (Example. A condenser located 10 feet below the ice machine has a calculated drop of 66 feet.) Line Set Rise/Drop 3. Insert the measured horizontal distance into the formula below. No calculation is necessary. The maximum rise is 35' (10.7 m). The maximum drop is 15' (4.5 m). 4. Add together the calculated rise, calculated drop, and horizontal distance to get the total calculated distance. If this total exceeds 150' (45.7 m), move the condenser to a new location and perform the calculations again. ! Caution If a line set has a rise followed by a drop, another rise cannot be made. Likewise, if a line set has a drop followed by a rise, another drop cannot be made. Calculated Line Set Distance The maximum calculated distance is 150' (45.7 m). Line set rises, drops, horizontal runs (or combinations of these) in excess of the stated maximums will exceed compressor start-up and design limits. This will cause poor oil return to the compressor. Maximum Line Set Distance Formula Step 1. Step 2. Step 3. Step 4.

When shortening or lengthening is required, do so before connecting the line set to the ice machine or the remote condenser. This prevents the loss of refrigerant in the ice machine or condenser. The receiver service valve is closed during shipment. Open the valve prior to starting the ice machine. The quick connect fittings on the line sets are equipped with Schraeder valves. Use these valves to recover any vapor charge from the line set. When lengthening or shortening lines follow good refrigeration practices, purge with nitrogen and insulate all tubing. Do not change the tube sizes. Evacuate the lines and place about 5 oz (143g) of vapor refrigerant charge in each line. 1. Remove the top and left side panels. 2. Remove the receiver service valve cap. 3. Backseat (open) the valve. 4. Reinstall the cap and panels. REMOVE FRONT, TOP, AND LEFT SIDE PANEL FOR ACCESS TO RECEIVER VALVE CONNECTING A LINE SET TURN COUNTERCLOCKWISE TO OPEN 1. Remove the dust caps from the line set, condenser and ice machine. 2. Apply refrigeration oil to the threads on the quick disconnect couplers before connecting them to the condenser. 3. Carefully thread the female fitting to the condenser or ice machine by hand. 4. Tighten the couplings with a wrench until they bottom out. 5. Turn an additional 1/4 turn to ensure proper brassto-brass seating. Torque to the following specifications: Liquid Line 10-12 ft lb.

Check all fittings and valve caps for leaks. 7. Make sure Schraeder cores are seated and Schraeder caps are on and tight. 2-18 Part Number 80-1620-3 Section 2 Installation Instructions Remote Ice Machine Usage with Non-Manitowoc Multi-Circuit Condensers WARRANTY FAN MOTOR The sixty (60) month compressor warranty, including thirty six (36) month labor replacement warranty, shall not apply when the remote ice machine is not installed within the remote specifications. The foregoing warranty shall not apply to any ice machine installed and/or maintained inconsistent with the technical instructions provided by Manitowoc Ice, Inc. Performance may vary from Sales specifications. S-Model ARI certified standard ratings only apply when used with a Manitowoc remote condenser. The condenser fan must be on during the complete ice machine freeze cycle (do not cycle on fan cycle control). The ice maker has a condenser fan motor circuit for use with a Manitowoc condenser. It is recommended that this circuit be used to control the condenser fan(s) on the multi-circuit condenser to assure it is on at the proper time. Do not exceed the rated amps for the fan motor circuit listed on the ice machine’s serial tag. If the design of the condenser meets the specifications, Manitowoc’s only approval is for full warranty coverage to be extended to the Manitowoc manufactured part of the system. Since Manitowoc does not test the condenser in conjunction with the ice machine, Manitowoc will not endorse, recommend, or approve the condenser, and will not be responsible for its performance or reliability. Important Manitowoc warrants only complete new and unused remote packages. Guaranteeing the integrity of a new ice machine under the terms of our warranty prohibits the use of pre-existing (used) tubing or condensers. HEAD PRESSURE CONTROL VALVE Any remote condenser connected to a Manitowoc SModel Ice Machine must have a head pressure control valve #836809-3 (available from Manitowoc Distributors) installed on the condenser package. Manitowoc will not accept substitute “off the shelf” head pressure control valves. INTERNAL CONDENSER VOLUME The multi-circuit condenser internal volume must not be less than or exceed that used by Manitowoc (see chart on next page). Do not exceed internal volume and try to add charge to compensate, as compressor failure will result. CONDENSER ∆T ∆T is the difference in temperature between the condensing refrigerant and entering air. The ∆T should be 15 to 20°F (-9.4 to -6.6°C) at the beginning of the freeze cycle (peak load conditions) and drop down to 12 to 17°F (-11.1 to -8.3°C) during the last 75% of the freeze cycle (average load conditions). REFRIGERANT CHARGE Remote ice machines have the serial plate refrigerant charge (total system charge) located in the ice maker section. (Remote condensers and line sets are supplied with only a vapor charge.) ! Caution Never add more than nameplate charge to ice machine for any application. QUICK CONNECT FITTINGS ! Caution Do not use a fan cycling control to try to maintain discharge pressure. Compressor failure will result. Part Number 80-1620-3 The ice machine and line sets come with quick connect fittings. It is recommended that matching quick connects (available through Manitowoc Distributors) be installed in the multi-circuit condenser, and that a vapor “holding” charge (5 oz.) of proper refrigerant be added to the condenser prior to connection of the ice machine or line set to the condenser. 2-19 Installation Instructions Section 2 NON-MANITOWOC MULTI-CIRCUIT CONDENSER SIZING CHART Ice Machine Model Refrigerant Type Heat of Rejection Charge S500 R-404A 6 lbs.

Normally, new installations do not require any adjustment. This optional accessory monitors ice making cycles and initiates cleaning procedures automatically. The AuCS® accessory can be set to automatically clean or sanitize the ice machine every 2, 4 or 12 weeks. Refer to the AuCS® Installation, Use and Care Manual for details. To ensure proper operation, follow the Operational Checks in Section 3 of this manual. Starting the ice machine and completing the Operational Checks are the responsibilities of the owner/operator. Adjustments and maintenance procedures outlined in this manual are not covered by the warranty. ! Warning Potential Personal Injury Situation Do not operate equipment that has been misused. abused, neglected, damaged, or altered/modified from that of original manufactured specifications. 2-22 Part Number 80-1620-3 Section 3 Ice Machine Operation Section 3 Ice Machine Operation Component Identification Water Distribution Tube Toggle Switch Water Curtain Dump Valve Check Valve sv3149 Ice Thickness Probe Bin Switch Water Level Probe Water Pump Water Inlet Location Water Inlet Valve (Located in Refrigeration Compartment) sv3150 Part Number 80-1620-3 3-1 Ice Machine Operation Section 3 Sequence Of Operation NOTE: The toggle switch must be in the ice position and the water curtain must be in place on the evaporator before the ice machine will start. INITIAL START-UP OR START-UP AFTER AUTOMATIC SHUT-OFF 1. Water Purge Before the compressor starts, the water pump and water dump solenoid are energized for 45 seconds, to completely purge the ice machine of old water. This feature ensures that the ice making cycle starts with fresh water. The harvest valve(s) is also energized during water purge, although it stays on for an additional 5 seconds (50 seconds total on time) during the initial refrigeration system start-up. When Used - The air compressor energizes for the last 10 seconds of the cycle. 2. Refrigeration System Start-Up The compressor starts after the 45 second water purge, and it remains on throughout the entire Freeze and Harvest Sequences. The water fill valve is energized at the same time as the compressor. The harvest valve(s) remains on for 5 seconds during initial compressor startup and then shuts off. FREEZE SEQUENCE 3. Prechill The compressor is on for 30 seconds (60 seconds initial cycle) prior to water flow, to prechill the evaporator. The water fill valve remains on until the water level probe is satisfied. 4. Freeze The water pump restarts after the prechill. An even flow of water is directed across the evaporator and into each cube cell, where it freezes. The water fill valve will cycle on and then off one more time to refill the water trough. When sufficient ice has formed, the water flow (not the ice) contacts the ice thickness probe. After approximately 10 seconds of continual water contact, the harvest sequence is initiated. The ice machine cannot initiate a harvest sequence until a 6 minute freeze lock has been surpassed. NOTE: Freeze lock is bypassed after moving the toggle switch from OFF to ICE position for the first cycle only. At the same time the compressor starts, the condenser fan motor (air-cooled models) is supplied with power throughout the entire Freeze and Harvest Sequences. The fan motor is wired through a fan cycle pressure control, therefore it may cycle on and off. (The compressor and condenser fan motor are wired through the contactor. As a result, anytime the contactor coil is energized, the compressor and fan motor are supplied with power.) 3-2 Part Number 80-1620-3 Section 3 Ice Machine Operation HARVEST SEQUENCE SAFETY TIMERS 5. Water Purge The control board has the following non-adjustable safety timers: The harvest valve(s) opens at the beginning of the water purge to divert hot refrigerant gas into the evaporator. The water pump continues to run, and the water dump valve energizes for 45 seconds to purge the water in the sump trough. The water fill valve energizes (turns on) and de-energizes (turns off) strictly by time. The water fill valve energizes for the last 15 seconds of the 45-second water purge. After the 45 second water purge, the water fill valve, water pump and dump valve de-energize. (Refer to “Water Purge Adjustment” for details.) • The ice machine is locked into the freeze cycle for 6 minutes before a harvest cycle can be initiated. Freeze lock is bypassed after moving the toggle switch from OFF to ICE position for the first cycle only. • The maximum freeze time is 60 minutes at which time the control board automatically initiates a harvest sequence (steps 5 & 6). • The maximum harvest time is 3.5 minutes at which time the control board automatically initiates a freeze sequence (steps 3 & 4). 6. Harvest The harvest valve(s) remains open and the refrigerant gas warms the evaporator causing the cubes to slide, as a sheet, off the evaporator and into the storage bin. The sliding sheet of cubes swings the water curtain out, opening the bin switch. The momentary opening and re-closing of the bin switch terminates the harvest sequence and returns the ice machine to the freeze sequence (Step 3 - 4.) When Used - The air compressor energizes after 35 seconds and remains energized throughout the entire harvest cycle. The air compressor will automatically energize for 60 seconds when the harvest cycle time exceeded 75 seconds in the previous cycle. AUTOMATIC SHUT-OFF WARM WATER RINSE CYCLE Closing the back of the evaporator allows ice to build up on the rear of the evaporator and the plastic evaporator frame parts. After 200 freeze/harvest cycles have been complete the control board will initiate a warm water rinse. After the 200th harvest cycle ends: • The Clean and Harvest LED’s energize to indicate the ice machine is in a warm water rinse. • The compressor and harvest valve remain energized. • The water pump energizes. • The water inlet valve energizes until water contacts the water level probe. • The compressor and harvest valve warm the water for 5 minutes, then de-energize. • The water pump remains energized for an additional 5 minutes (10 minute total on time) then deenergizes. 7. Automatic Shut-Off When the storage bin is full at the end of a harvest sequence, the sheet of cubes fails to clear the water curtain and will hold it open. After the water curtain is held open for 30 seconds, the ice machine shuts off. The ice machine remains off for 3 minutes before it can automatically restart. The ice machine remains off until enough ice has been removed from the storage bin to allow the ice to fall clear of the water curtain. As the water curtain swings back to the operating position, the bin switch re-closes and the ice machine restarts (steps 1 - 2), provided the 3 minute delay period is complete. Part Number 80-1620-3 NOTE: The warm water rinse cycle can be terminated by moving the toggle switch to the OFF position, then back to ICE. 3-3 Ice Machine Operation Section 3 Operational Checks ICE THICKNESS CHECK GENERAL The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8" (.32 cm). Manitowoc ice machines are factory-operated and adjusted before shipment. Normally, new installations do not require any adjustment. To ensure proper operation, always follow the Operational Checks: • when starting the ice machine for the first time • after a prolonged out of service period • after cleaning and sanitizing NOTE: Routine adjustments and maintenance procedures are not covered by the warranty. WATER LEVEL The water level sensor is set to maintain the proper water level above the water pump housing. The water level is not adjustable. If the water level is incorrect, check the water level probe for damage (probe bent, etc.). Clean the water level probe with ice machine cleaner, rinse thoroughly and re-check operation. Repair or replace the probe as necessary. NOTE: Make sure the water curtain is in place when performing this check. It prevents water from splashing out of the water trough. 1. Inspect the bridge connecting the cubes. It should be about 1/8" (.32 cm) thick. 2. If adjustment is necessary, turn the ice thickness probe adjustment screw clockwise to increase bridge thickness, counterclockwise to decrease bridge thickness. Set at 1/4” gap between ice machine and evaporator as starting point, then adjust to achieve a 1/8” bridge thickness. NOTE: Turning the adjustment 1/3 of a turn will change the ice thickness about 1/16" (1.5 mm). ADJUSTING SCREW 1/8” ICE BRIDGE THICKNESS SV3132 Ice Thickness Check 3. Make sure the ice thickness probe wire and the bracket do not restrict movement of the probe. Water Level Probe Location 3-4 Part Number 80-1620-3 Section 3 Ice Machine Operation HARVEST SEQUENCE WATER PURGE The harvest sequence water purge adjustment may be used when the ice machine is hooked up to special water systems, such as a de-ionized water treatment system. ! Warning • During the harvest sequence water purge, the water fill valve energizes and de-energizes by time. The water purge must be at the factory setting of 45 seconds for the water fill valve to energize during the last 15 seconds of the water purge. If it is set to less than 45 seconds, the water fill valve will not energize during the water purge. Disconnect electric power to the ice machine at the electrical disconnect before proceeding. Important The harvest sequence water purge is factory-set at 45 seconds. A shorter purge setting (with standard water supplies such as city water) is not recommended. This can increase water system cleaning and sanitizing requirements. • The harvest sequence water purge is factory set for 45 seconds. Repositioning the jumper will set the harvest water purge to 0 seconds. This setting does not affect the SeCs or AuCs (cleaning) sequences. 45 second setting 0 second setting SV3139 SV3140 Water Purge Adjustment For your safety and to eliminate errors, we recommend that a qualified service technician make the harvest water purge adjustment. Part Number 80-1620-3 3-5 Ice Machine Operation Section 3 THIS PAGE INTENTIONALLY LEFT BLANK 3-6 Part Number 80-1620-3 Section 4 Maintenance Section 4 Maintenance General Cleaning the Condenser You are responsible for maintaining the ice machine in accordance with the instructions in this manual. Maintenance procedures are not covered by the warranty. GENERAL ! Warning If you do not understand the procedures or the safety precautions that must be followed, call your local Manitowoc service representative to perform the maintenance procedures for you. We recommend that you perform the following maintenance procedures a minimum of once every six months to ensure reliable, trouble-free operation and maximum ice production. Ice Machine Inspection ! Warning Disconnect electric power to the ice machine and the remote condensing unit at the electric service switch before cleaning the condenser. Check all water fittings and lines for leaks. Also, make sure the refrigeration tubing is not rubbing or vibrating against other tubing, panels, etc. Do not put anything (boxes, etc.) on the sides or back of the ice machine. There must be adequate airflow through and around the ice machine to maximize ice production and ensure long component life. Exterior Cleaning Clean the area around the ice machine as often as necessary to maintain cleanliness and efficient operation. Use cleaners designed for use with stainless steel products. ! Warning Disconnect electric power to the ice machine head section and the remote condensing unit at the electric service switches before cleaning the condenser. A dirty condenser restricts airflow, resulting in excessively high operating temperatures. This reduces ice production and shortens component life. Clean the condenser at least every six months. Follow the steps below. ! Warning The condenser fins are sharp. Use care when cleaning them. 1. The washable aluminum filter on self-contained ice machines is designed to catch dust dirt lint and grease. Clean the filter with a mild soap and water. 2. Clean the outside of the condenser with a soft brush or a vacuum with a brush attachment. Be careful not to bend the condenser fins. 3. Shine a flashlight through the condenser to check for dirt between the fins. If dirt remains: A. Blow compressed air through the condenser fins from the inside. Be careful not to bend the fan blades. B. Use a commercial condenser coil cleaner. Follow the directions and cautions supplied with the cleaner. Continued on Next Page... Sponge any dust and dirt off the outside of the ice machine with mild soap and water. Wipe dry with a clean, soft cloth. Heavy stains should be removed with stainless steel wool. Never use plain steel wool or abrasive pads. They will scratch the panels. Part Number 80-1620-3 4-1 Maintenance Section 4 4. Straighten any bent condenser fins with a fin comb. “COMB” DOWN ONLY Water-Cooled Condenser and Water Regulating Valve Symptoms of restrictions in the condenser water circuit include: • Low ice production • High water consumption • High operating temperatures • High operating pressures CONDENSER If the ice machine is experiencing any of these symptoms, the water-cooled condenser and water regulating valve may require cleaning due to scale build-up. FIN COMBS Because the cleaning procedures require special pumps and cleaning solutions, qualified maintenance or service personnel must perform them. AlphaSan SV1515 Straighten Bent Condenser Fins 5. Carefully wipe off the fan blades and motor with a soft cloth. Do not bend the fan blades. If the fan blades are excessively dirty, wash with warm, soapy water and rinse thoroughly. !

The active ingredient in AlphaSan is the element silver in the form of silver ions (Ag+). AlphaSan slowly releases silver ions via an ion exchange mechanism. When AlphaSan is compounded directly into a plastic part, a controlled release of silver ions from the surface is regulated to maintain an effective concentration at or near the surface of the plastic ice machine part. AlphaSan’s unique ability to effectively control the release of silver not only protects against undesired discoloration of the plastic, but also will last the life of the plastic part. Although AlphaSan helps prevent bio-film build up it does not eliminate the need for periodic cleaning and maintenance. AlphaSan has no adverse effect on the taste of the ice or beverage. Part Number 80-1620-3 Section 4 Maintenance Guardianf Slime is a leading cause of ice machine breakdowns and biological growth is a health concern. The Guardianf system releases chlorine dioxide on a controlled basis to inhibit the growth of bacteria and fungi that form slime and cause malodors in the food zone of ice machines. SACHET INSTALLATION/REPLACEMENT PROCEDURE 1. Loosen the left screw and open the left front door. The right front panel does not need to be removed. The Guardianf will not control mineral or other water borne buildup. Your water quality will determine the length of time before mineral buildup affects ice machine performance.
