Install with arrow pointing in direction of flow (toward compressor). Reverse flow may cause internal damage. Clean and deburr piping ends to provide a good brazing surface. Use an inert gas, such as nitrogen, to pass through the lines while brazing, to prevent formation of copper oxides.
In this design one drier is ahead of the expansion device, and the other drier is ahead of the check valve. When installed in these locations, the flow through each drier is always in the same direction, see Figure 2. Standard filter-driers will not tolerate flow in the reverse direction.
The refrigerant flow direction, indicated by an arrow on the filter drier shells' tags, should be complied with. Assembly can be performed in any position, but not vertically with the outlet connection oriented downwards.
If still someone makes a mistake of fitting the drier in wrong direction, the same will not serve the purpose for which it was installed - Filtration and Moisture removal. In addition it will cause pressure drop and the drier has to be replaced.
Consequences– If the technician makes the mistake of installing the drier in the wrong direction, the drier will not work and serve the purpose for which it has been designed. So, no filtration of contamination and no drying of moisture.
The most common problem you will face with a backwards facing filter is simple inefficiency. If your furnace is forced to blow air through the non-porous end of a filter, it will take more energy to do so. The blower will be overworked and you will pay more money for your heating.
Which Direction does a Liquid line Filter Drier Go? The arrow on the filter drier will point the flow direction. Most of the filter driers are one way filter drier. The Bi-flow filter drier is designed for heat pump system, with double way flow directions.
Suction line driers, on the other hand, are typically used as a temporary solution following a system burnout or when servicing the unit. They're installed on the suction line to capture acids and contaminants that may have been released during a compressor malfunction.
The function of a suction line accumulator in a heat pump or refrigeration system is to catch and hold any unused portion of the system charge. The device must also prevent liquid slugging of the compressor and excessive refrigerant dilution of the compressor oil.
If you install your filter in the wrong direction, air will have a hard time flowing through the filter's material and your air handler will have to work overtime to make up for the loss of airflow. This is not only a waste of energy, but it can also possibly damage your air conditioner or heating system.
No, you should never run your AC without a filter!
The purpose of your air filter is to clean your home's air and to keep your AC system dust- and dirt-free, which is why it's important to only run your AC with a filter installed.
They're especially suited for system cleanup after a burnout, or when major work has been performed on the system. 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.
Two copper lines in an AC unit serve as refrigerant lines. The larger line that carries cool gas and is usually insulated is the suction line. The other refrigerant line is a smaller uninsulated line that carries warm liquid and is often called the liquid line.
The liquid line drier is mainly to absorb moisture or small particles where the suction line drier is larger and designed mainly for clean up of a burnout compressor .
An AC suction line is a refrigerant pipe that runs under low pressure from the compressor to the evaporator coil. It sucks air from outside the building and pulls it inside. This helps cool down the house during hot summer days.
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.
Suction Line Filter-Driers and Suction Filters should be installed as close to the compressor as possible. If a suction vibration eliminator is used, the drier or filter should be installed upstream of it.
For filters installed in a ceiling or wall return, the arrow should face the ductwork, meaning it should point in the direction of the ceiling or wall. This helps guide the air smoothly through the filter entering the HVAC system.
The refrigerant flow direction is indicated by an “IN” mark in the inlet shell of the filter drier and by an arrow on the filter drier tag. It must be necessarily respected. Mounting of filter drier receivers should always be performed vertically, refrigerant inlet up, for proper use of the receiver part.
All furnace filters have arrows around the edge that indicate the direction of the airflow. The arrow on your air filter should point towards the blower in your HVAC unit. This ensures that the filter catches particles and debris before they enter the system, protecting the internal components from damage.
If the filter is placed in the wrong direction, the finer pores on the other side of the filter will make it difficult for air to pass through the system. When that happens, there will also be a decrease in the cooling performance of the AC.
