Where must a suction line filter be placed in a heat pump after a compressor motor burnout?
Where must a suction line filter be placed in a heat pump after a compressor motor burnout?
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. First, make sure the burnout is “severe” by testing the acidity of the oil from the burned out compressor using the Sporlan TA-1 Acid Test Kit.
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.
Should I install a suction line filter without burnout?
Emerson’s ASD premium filter drier. Compressor manufacturers recommend the installation of suction line filterdriers to protect their equipment from contaminants left in the system after a burnout. Failure to follow instructions may result in filter-drier failure, system damage, or personal injury.
Where is the only true suction line?
The suction line is to return gas to the compressor. It is between the evaporator and compressor on a standard cooling system and between the reversing valve and the compressor on a heat pump.
When to replace a suction line filter drier?
Suction line filter-driers used to clean up a system after a burnout should be replaced until the system is known to be clean and no longer tests positive for acids in the system. A suction line filter-drier with an excessive pressure drop across it should not be left in a system.
When to use a suction drier in air conditioning?
In air conditioning, we rarely install suction driers unless we know there is acid contamination, such as in the case of a compressor burnout. Interestingly, Copeland actually recommends suction driers in ALL applications in bulletin AE24-1105 R5 .
Why do air filters need to be replaced in a compressor?
compressor: it will cause wear to the compressor element, valves and other parts. It will also save your compressors oil, oil separator, oil filters and all other moving parts. Different types of air filters. The compressor air filters need to be cleaned and/or replaced regularly.
Where to put a compressor in a workshop?
Also, if your compressor is installed in a very dusty or dirty environment (metal workshop with oily air, wood workshop with a lot of dust, sand-blasting workshop, etc) … do yourself and your compressor a favor: put the compressor in its own room with fresh air, or install ducting to supply the compressor with fresh air.
How to choose the correct replacement gas compressor?
There are different ways to choose the correct replacement compressor: 1. Refer to the application section looking up application by Make, Year and Model and select the compressor needed. If it is not listed in the application section then… 2. Locate the Identification Tag on the compressor body – the part number is stamped on the tag.
In air conditioning, we rarely install suction driers unless we know there is acid contamination, such as in the case of a compressor burnout. Interestingly, Copeland actually recommends suction driers in ALL applications in bulletin AE24-1105 R5 .
How to replace suction filter and liquid drier?
• Install a high-capacity acid removal suction and liquid drier or removable core (s). • Some contractors will add acid neutralizers such as Acid Away in certain applications. • Return after running the system for a while and test for acid and replace high capacity filter/driers with new ones if required.
When to change the core of a suction line?
The pressure drop across the filter-drier should be checked during the first hour of operation to determine if the cores need to be changed. Any pressure loss in the suction line also reduces system capacity significantly.
