14-3-4 Filter Drier Equipping Method when Compressor is Breakdown
1. Because DVM plus
2
uses the plural number of compressors, if one unit of compressor is breakdown, lubricating oil or
refrigerant may get contaminated and it may affect to the other compressor or the operating component such EEV.
Therefore, if replacing the compressor after proving that the compressor is breakdown, equip the Filter Drier having
options that are specified on the liquid pipe in front of the outdoor unit same as below illustration.
1. Same as above illustration, prevent spreading of the contaminant from the breakdown compressor by equipping the Filter Drier
to the liquid pipe side of each outdoor unit after replacing the compressor.
2. Applied Filter
2. Because DVM plus
2
is the air-conditioning and heating product, must use the Bi-Directional Filter Drier.
Use the Filter Drier specified on the below according to the outdoor unit's capacity.
• Must use the Bi-Directional Filter Drier that are stated on the above Table.
• The installation location of the Filter Drier is the liquid pipe in front of the outdoor unit as stated the above
illustration. (Do not install on the gas side's pipe)
• If opening and leaving the Seal Cap on the both side of the Filter Drier for a while, the efficiency of moisture
absorption by the Drier is decreased. So, open the Seal Cap right before the installation.
• If the foreign substance is accumulated on the Filter excessively, clogging may be generated; so, must be
careful. (Need to replace when the temperature difference between before and after of Filter Drier is over 1˚C)
