Where do you put a suction line filter-drier?
Installation. The Catch-All Filter-Drier can be installed directly in the suction line by removing a portion of the line. After clean-up, the Catch-All Filter-Drier is generally left in the line.
When Should a suction line filter-drier be installed?
Emerson suction line filter-driers incorporate a protective filter, plus desiccant blended for maximum moisture and acid removal. Compressor manufacturers recommend the installation of suction line filter-driers to protect their equipment from contaminants left in the system after a burnout.
Where is the only permanent suction line on a heat pump?
The center line on the bottom is always the suction line to compressor/accumulator. One of the side lines is connected to the outdoor coil and the other side line is connected to the indoor coil.
Where is the refrigerant filter-drier found?
Sometimes filter driers can be found in the liquid line of the compressor. The segment of piping leading to the compressor inlet is called the suction line, while the segment following the compressor outlet is called the liquid line.
What happens if you put a filter drier in backwards?
When installing a new filter drier, an arrow on the filter drier’s housing will indicate which direction refrigerant is designed to flow. If installed backwards, the filter drier will become useless. Overheating may scorch the internal filters, drying agents, and other important parts of the dryer.
Can you put a suction line drier on a heat pump?
THE SUCTION LINE DRIER LOCATION – A filter-drier should be installed in the suction line to clean up a heat pump after a severe hermetic motor burnout. This drier can be installed either before or after the accumulator, but always between the 4-Way valve and the compressor.
What happens if filter drier is installed backwards?
If installed backwards, the filter drier will become useless. Take care not to overheat the newly installed filter drier when using a torch for brazing a sweat-type drier to the liquid line. The brazed connections must be thoroughly cleaned and fluxed when called for.
How do I know if my filter drier is bad?
Bad A/C receiver drier symptoms
- Unusual noises.
- Leakage.
- Bad odour.
- Ineffective cooling.
- Cloudy sight glass.
How do I know if my receiver drier is bad?
Can a filter-drier be used in a suction line?
If the proper style drier is not available, then a suction line filter-drier can be used in the suction or liquid line; and a liquid line filter-drier can be used in the suction line. The pressure drop characteristics of the two types of driers are essentially the same for a given line size.
Where do you put a filter drier on a heat pump?
Install a reversible filter-drier in the common liquid line. If possible, install a drier in the common suction line. A filter-drier should be installed in the suction line to clean up a heat pump after severe hermetic motor burnout.
How to install a reversible drier on a heat pump?
Install an oversized drier in the common liquid line and, if possible, a drier in the common suction line. Run the unit in one mode of operation for a day. Then replace the liquid line drier with a reversible filter-drier. Install a reversible filter-drier in the common liquid line. If possible, install a drier in the common suction line.
Where do you put a drier in an expansion unit?
Install the same size drier (or an oversized drier) in the liquid line ahead of each expansion device, and a drier in the common suction line. In units with two liquid line driers, both should be changed. Install an oversized drier in the common liquid line and, if possible, a drier in the common suction line.
