RMD EC Cooling System Typical Installation

• Always plan for future maintenance and service. Units should have easy access or access panels. Grills, boxes, or racking nearest the evaporators should be removable.
• Standard Line Sets should be 50’ or less. Over 50’ an oil separator and suction line accumulator is required. Extended runs may require larger line sizes and 3 oz of oil must be added for every 10’ feet over 35’. Insulate suction line, liquid line insulation is optional.
• Excessive number of turns in line set will cause refrigerant flow problems. This could cause early compressor failure. Suction line accumulators are recommended on all applications. Required if working lower than the normal 55°-65°F operating range from wine cellar.
• Drain line must flow with gravity to drain or pump.
• The system is controlled by a pump down control system. There is no control wiring between thermostat and condensing unit.
• The line connections at Fan Coil and Condensing Unit may not be the same as the required line sizes dictated for the system capacity.
• BTUH Capacity calculated at 17° TD, 38° ST, 55° Room
• The use of oversized condensing units can lead to poor wine room evaporator performance and possible system failure. When installing our wine room evaporator, it is recommended that condensing units be sized less than or equal to the evaporator capacity.
• USCS Cooling units are designed to minimize noise and vibration. To reduce and eliminate amplification of existing noise or vibration, extreme care must be taken during installation to identify contributing factors in the environment. Please refer to supplied installation instructions and use proper installation materials to minimize acoustic impact.
