Page 16: Refrigerant Piping Connection
Unit Installation Unit Installation Field Copper Tubing Connection To ensure satisfactory operation and performance, the following points should be noted for the field tubing arrangements of the complete refrigerant cycle. a) Liquid loops or oil traps must be provided according to the position of the outdoor and the indoor units (depending on whether the indoor unit is above or below the outdoor unit). - Page 17 Unit Installation Unit Installation Charging Hose Most field-charging is done using standard service hoses. Hoses are made in different colors with different working pressures and with different leak rates but the most important point is the presence or absence of hoses This slows evacuation and vapor charging dramatically.
