Chiller must be installed levelly to maintain proper compressor oil return (level adjustment kit included with manifold piping kit (option).2. Wiring and piping shown are general points-of-connection guides only and are not intended for a specific installation. Wiring and piping shown are for a quick overview of system and arenot in accordance with recognized standards.3. All wiring must comply with applicable local and national codes.4. All piping must follow standard piping techniques. Refer to Carrier System Design Manual part 3, Carrier E20-II software Refrigerant Piping program, or appropriate ASHRAE (AmericanSociety of Heating, Refrigerating, and Air-Conditioning Engineers) handbook for details on proper piping sizes and design.5. See product data for minimum system fluid volume. This system may require the addition of a holding tank to ensure adequate volume.6. Hot gas lines should rise above refrigerant level in condenser circuit. With 30MPA/09DP matched condensers, this is accomplished internally in the 09DP unit. Double riser may berequired; Check 30MPA line sizing chart.7. Trap should be installed on hot gas lines to prevent condenser oil and refrigerant vapor migration from accumulating in the compressor during off cycle.8. Pitch all horizontal lines downward in the direction of refrigerant flow.9. For piping lengths greater than 50 ft (15 m), provide support to liquid and gas lines near the connections to the condenser coil.10. For pressure relief requirements, see latest revision of ASHRAE Standard 15, Safety Code for Mechanical Refrigeration.11. Operating environment — Chiller should be installed in an indoor environment where the ambient temperature is between 40 to 104°F (4 to 40°C) with a relative humidity (non-condensing)of 95% or less. To ensure that electrical components operate properly, do not locate the chiller in an area exposed to dust, dirt, corrosive fumes, or excessive heat and humidity.12. Inverted trap required at condenser for 09DPM065-130.
