Manual background

NOTES:

1. Chiller must be installed levelly to maintain proper compres- sor oil return.

2. Wiring and piping shown are general points-of-connection guides only and are not intended for a speci®c installation. Wiring and piping shown are for a quick overview of system and are not 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 soft- ware Refrigerant Piping program, or appropriate ASHRAE (American Society of Heating, Refrigeration, and Air Condi- tioning Engineers) handbook for details on proper piping sizes

and design.

5. See Table 3 on page 17 for minimum system ¯uid volume. This system may require the addition of a holding tank to en- sure adequate volume.

6. Hot gas lines should rise above refrigerant level in condenser circuit. Double riser may be required; check compressor mini- mum capacity.

7. Trap should be installed on hot gas lines to prevent con- denser oil and refrigerant vapor migration from accumulating on compressor heads during off cycle.

8. Pitch all horizontal lines downward in the direction of refrig- erant ¯ow.

9. For piping lengths greater than 50 ft, 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.
