Page 10: Refrigeration Components
REFRIGERATION COMPONENTS Mueller CP2 compact chillers are designed to operate with two Mueller 5-horsepower E-Star HiPerForm “HPF/ ESE” condensing units for maximum performance and efficiency. Refer to the E-Star HiPerForm “HPF/ESE” condensing unit manuals for technical information. EVAPORATOR The Mueller compact chiller uses two totally enclosed, heavy-duty, stainless steel evaporators to provide years of trouble-free operation when properly installed and controlled. -
Page 11: Electrical Components
ELECTRICAL COMPONENTS The Mueller compact chiller has a complete electrical control system. The electronic temperature control is housed in a separate enclosure. The multi-stage chiller control must be mounted and wired to the flow switches, condensing units, temperature sensors, and pump. All wiring must be performed in accordance with the regulatory agency for the installation locality. -

Section 3.0 – Installation INSPECTION Because it is possible for equipment damage to occur during shipment, Paul Mueller Company requires inspecting all equipment before unloading it from the freight truck. Carefully inspect the equipment for hidden damage. It may be difficult to collect for damage if it is not found prior to unloading. It is important to note any damage on the bill of lading and have the driver sign it. - Page 13 FIGURE 4: FORK LIFT CRATED FIGURE 5: SKID REMOVAL Mueller Compact Chiller, Models CP2-10 and CP2-20 Effective December 21, 2011 Installation and Operation Manual, Part No. 8826880 Revised June 7, 2023...

Page 14: Location
• Efficiency: Locate the chiller as close as possible to the Mueller Accu-Therm plate cooler. This will improve efficiency by reducing heat gain and flow restrictions in the chilled liquid solution piping. CHILLED SOLUTION PIPING The piping between the compact chiller and the Accu-Therm plate cooler should be a minimum of 3-inch Schedule-40 or -80 PVC, stainless steel, or copper pipe. -
Page 15: Condensing Unit Installation
IMPORTANT: The circulation of controlled warm water or a completely drained evaporator is mandatory during pump-down or refrigerant recovery to eliminate evaporator damage due to freezing.

Page 21: Section 7.0 - Multi-Stage Chiller Control Installation
ELECTRICAL REQUIREMENTS The Mueller multi-stage chiller control requires a 208 V/240 V/277 V power supply, fused at 20 amps maximum, or a 380 V/480 V power supply, fused at 10 amps maximum. A lockable disconnect is provided in accordance with CE Standard EN60947-3. -
Page 22: Section 8.0 - Multi-Stage Chiller Control Electrical Wiring
When sensors are installed in pipes discharging into a reservoir, Mueller recommends the sensors be installed in the six o’clock position. Care must be taken to never deform the sensor housing as damage to the enclosed circuit board could result. Mueller does not recommend the use of copper compression fittings on the digital temperature sensor. -
Page 23: Field Wiring
FIELD WIRING The Mueller multi-stage chiller control may be wired to provide 24-VAC output, dry switch closures, or any combination of the two. Please refer to the following diagrams for wiring procedures.
