After determining milk volume, close milk outlet valve on cooler. 2. Disconnect hose from fitting on outlet valve and dispose of milk that drains from hose and tube. 3. Remove hex nut and quick-connect tube coupling from outlet valve and place in wash vat for hand cleaning. 4. If gauge is used between milkings and cooler will not be washed immediately, close outlet valve and dispose of milk in gauge tube. Properly clean and sanitize the gauge tube by disconnecting hoses from cooler and flushing from the top to remove milk residue. Then, reconnect the hoses. Emptying Cooler The following steps must be taken before pumping milk out of the cooler: 1. ! IMPORTANT: Be sure vent assembly is over milk inlet opening and release hold-down clamps on manhole cover to provide additional venting. To equalize pressure inside and outside of cooler during filling, emptying, and washing, it is mandatory that vent assembly be kept on the inlet at all times. 2. 5.7 Move selector switch on control cabinet to “OFF” position. Empty cooler and rinse out remaining milk solids with tepid water. Washing Cooler After cooler has been emptied, it should be washed in the following manner: 1. Remove the nut and locking cap from the outlet valve. Remove the pump suction hose from the hanger and attach to the outlet valve. If the milk cooler is equipped with an external gauge, connect the external gauge quick connect to the pump discharge quick connect. 2. To wash external gauge tube with Mueller Matic, connect lower gauge hose to fitting located above and to the right of the outlet. Be sure upper hose is connected to fitting on top of cooler. 3. Be sure the vent assembly is properly installed to equalize pressure inside and outside of cooler during washing. 4. Remove the dispenser bowl labeled “Detergent,” discard its contents, and rinse the bowl. Add the proper amount of detergent recommended for the brand used. The concentration should be based on the gallons of wash water shown in Table 2, “Water Consumption Chart.” HAZARD: Never mix chlorinated sanitizers or detergent with acid. Be sure that there is no previous product residue in the bowl before adding acid. 5. Move selector switch on control cabinet to “WASH” position and turn Mueller Matic timer knob to first rinse (clockwise only) to automatically start system. The Mueller Matic will pre-rinse, wash, rinse, and acid rinse, then turn off automatically. 6. Sanitizing should be done immediately before milking according to procedures outlined under Section 5.1, “First Milking.” 7. If the Mueller Matic does not operate properly, consult Section 6.6, the troubleshooting chart. Model “OE” Low-Voltage Refrigeration Control and Cleaning System Installation and Operation Manual, Part No. 8823647 27 Effective March 31, 2000 Revised August 16, 2005 SECTION 6.0 - GENERAL MAINTENANCE INSTRUCTIONS 6.1 Cooler Maintenance Although Mueller milk coolers are designed and built to provide years of trouble-free service, the following precautions and maintenance schedule should be observed: 6.2 1. Always rinse out cooler immediately after emptying to be sure that milk does not dry on the cooler surface. 2. Keep all surfaces of cooler, inside and outside, clean and free of deposits of foreign matter. 3. Do not allow tools, clamps, or any wet objects to lie on the surface for a prolonged period of time. 4. Do not enter cooler with shoes on or allow surface to be scratched in any way. 5. Use only those cleaning solutions or materials specifically recommended for use on stainless steel. Follow the chemical manufacturers’ recommendations and warnings for chemical usage. Never use steel wool, files, coarse sand paper, or emery cloth. Mueller Matic Automatic Washing System Maintenance Mueller Matics are engineered to give you maximum service with minimum care. In order to ensure years of trouble-free service, the following periodic inspections and servicing should be performed: 1. Clean water supply strainers regularly as follows: a. Close water supply valves and remove hose assemblies. b. Remove, clean, and replace strainers. c. Re-install hose assemblies. c. Open water supply valves. 2. Clean dispenser bowl strainers as follows: a. Remove bowl. b. Remove bowl strainer retainer and bowl strainer. c. Clean strainer screen and install in the reverse order. 3. Inspect and lubricate dispenser lid O-rings with sanitary lubricant on a monthly basis. 4. Remove drain valve and clean the screen located between the rubber coupling and the drain valve. NOTE: The electric drain valve is a normally open valve. 5. The timer is a precision electrical instrument. DO NOT ATTEMPT to disassemble the timer. 6. The “Time Cycle Chart” (Table 3) shows the sequence of operations as governed by the timer. It indicates when each circuit is energized and is keyed to the terminals as numbered on the timer and wiring diagrams. 7. If at any time your Mueller Matic does not operate, consult the Mueller Matic troubleshooting chart in Section 6.6. Model “OE” Low-Voltage Refrigeration Control and Cleaning System Installation and Operation Manual, Part No. 8823647 28 Effective March 31, 2000 Revised August 16, 2005 6.3 Determining Chemical Usage The chemical usage will vary depending on the make and manufacturer, the amount of water required for each cycle, and the water quality. It is very important to have your Chemical Supplier test the water supply and determine the proper usage and concentrations of each specific chemical. This information should be posted on a cleaning chart near the milk cooler. (See Table 2 for water usage.) ! 6.4 IMPORTANT NOTE: Improper chemical usage can cause non-warranted and non-repairable damage to your stainless steel milk cooler. Chemicals should be purchased from a reputable source that specializes in the proper application and usage of dairy cleansers for clean-inplace (CIP) applications. Chemical Cautions (Additional Cautions are Listed in Section 2.18) • Proper safety precautions must be followed when handling chemicals. • Read and abide by all Material Safety Data Sheets (MSDS), labels, instructions, warnings, and health hazard information provided by the Chemical Manufacturer. • Eye, face, and skin protection should be worn at all times! • Prime peristaltic pumps in a glass jar only. Do not prime the pumps in the milk cooler. • Without proper dilution, chemicals can damage the stainless steel milk cooler. • Never mix chemicals — a deadly gas may be created. • Ensure that all drains are properly trapped to prevent mixed chemical gasses from reentering the workplace. • Store chemicals in an area protected from freezing and out of direct sunlight. • Store chemicals in an area that prevents access by children or unauthorized individuals.
