Carrier 38HDR018-060 specifications 38HDF018-036 Physical Data

Only use factory specified liquid-line filter driers with rated working pressures less than 600 psig.

NOTE: Do not install a suction-line filter drier in liquid line.

MAKE PIPING SWEAT CONNECTIONS — Remove plastic caps from liquid and suction service valves. Use refrigerant grade tubing. Service valves are closed from the factory and are ready for brazing. After wrapping the service valve with a wet cloth, the tubing set can be brazed to the service valve using ei- ther silver bearing or non-silver bearing brazing material. Con- sult local code requirements. Refrigerant tubing and the indoor coil are now ready for leak testing.

NOTE: Unit is shipped with R-410A factory charge indicated on nameplate.

Pass nitrogen or other inert gas through piping while braz- ing to prevent formation of copper oxide.

To avoid damage while brazing, service valves should be wrapped with a heat-sinking material such as a wet cloth.

When brazing tubing sets to the service valves, a brazing shield MUST be used to prevent damage to the painted unit surface.

PROVIDE SAFETY RELIEF — A fusible plug is located in unit suction line; do not cap this plug. If local code requires additional safety devices, install as directed.
