TECHNICAL SUPPORT This manual provides basic installation and operating information for Mueller E-Star OESE condensing units. Please contact your local Paul Mueller Company Sales and Service Representative if you require additional technical assistance pertaining to installation or operating procedures. Manufacturer’s support is available by contacting the following:... -
Page 9: Section 2.0 - Installation
IMPORTANT: Equipment used to move or lift this equipment must be rated for the weight of the equipment. See Table 1 for equipment weight. LOCATION When choosing a location for the Mueller E-Star OESE condensing unit, consider these items: • Environment: The unit must be located where it is protected from extreme temperatures of –30°F (–34.4°C) and below or 115°F (46.1°C) and above. - Page 10 Discharge Line Horsepower Liquid Line Suction Line (Fre-Heater®) ⁄ ⁄ ⁄ ⁄ ⁄ ⁄ ⁄ ⁄ ⁄ ⁄ ⁄ ⁄ Mueller E-Star OESE 3.5 and 5 HP HFC Condensing Unit Installation and Operation Manual, Part No. 8828747 Effective April 13, 2020...

Connecting high-voltage control to this circuit will cause equipment failure and a possible electrical hazard. The control circuit can be modified for high-voltage supply in installations that do not utilize a Mueller low-voltage refrigeration control. Refer to Section 7.0 for details. -
Page 12: Section 3.0 - Refrigerant Charging
Section 3.0 – Refrigerant Charging EPA REFRIGERANT REGULATIONS Mueller E-Star OESE condensing units are designed to operate with R-507 refrigerant. R-507 is specified by the ASHRAE Standard 34 Safety Classification as an A-1 refrigerant with low-flame propagation and low toxicity. -
Page 13: Final Operating Charge
When refrigerants come in contact with an open flame or a high heat source, dangerous gases will form. This is characterized by a strong acidic odor. Immediately vacate the area and ventilate prior to reentry. Mueller E-Star OESE 3.5 and 5 HP HFC Condensing Unit Installation and Operation Manual, Part No. 8828747... -
Page 14: Section 4.0 - Operating Features
Section 4.0 – Operating Features REFRIGERANT CYCLE Mueller E-Star OESE condensing units utilize an thermal expansion valve (TEV) that controls the evaporator’s superheat. The expansion valve must be field adjusted to maintain the milk coolor’s evaporator’s superheat at 4–6°F (2.2–3.3°C) or the chiller’s superheat at 10–12°F (5.6–6.7°C). - Page 15 (access ports P2) to ensure the compressor is protected against damage caused by liquid refrigerant slugging.

Page 16: Section 5.0 - Expansion Valve
10–12°F. Proper location and sizing of the thermal expansion valve is critical. Refer to Section 5.2 for the superheat adjustment procedure. An externally equalized TEV must be used on Mueller milk cooling applications. A sight glass must be installed at the TEV inlet. -
Page 17: Checking And Adjusting Superheat
• Actual suction line temperature equals 40°F. Results: 60 PSIG • 40°F – 34°F = 6°F (4.4°C – 1.1°C = 3.3°C) superheat at evaporator. Mueller E-Star OESE 3.5 and 5 HP HFC Condensing Unit Installation and Operation Manual, Part No. 8828747 Effective April 13, 2020... -
Page 18: Section 6.0 - Accumulator Heat Exchanger
IMPORTANT: The Mueller accumulator heat exchanger utilizes a special “pancake” heat exchange coil. The use of a generic (spiral) accumulator heat exchanger will severely reduce cooling capacity of the E-Star OESE condensing unit and may cause premature compressor failure. Use genuine Mueller replacement parts only. -
