(1) models that can see the upper and lower evaporator interfaces There are upper and lower steamer interface boxes on the back of the refrigeration body. The drilling position is generally selected in the middle of the bottom of the commercial refrigeration freezer compartment and the middle of the top of the refrigerating compartment. Both eyes should be close to the back wall.
(2) Models that cannot see the upper and lower evaporator interface boxes. commercial refrigeration. Models without upper and lower evaporator interface boxes on the back of the body. The drilling position is generally on the side of the air return pipe. For commercial refrigeration models, drill holes on the left or right side of the bottom of the freezer, and the holes must be close to the back and side walls of the commercial refrigeration body; drill holes on the right side of the water receiving box in the cold storage room, that is, the holes are in the evaporator The return trachea exits the commercial refrigeration side of the body. For models with the air return pipe on the right, drill holes on the right side of the bottom of the freezer compartment and drill holes on the right side of the interface box of the refrigerator compartment.

(l) The length of the capillary is determined. For commercial refrigeration from 180L to 220L, the new capillary length is 2.2 meters to 2.5 meters. It is also possible to straighten the original capillary tube and add the inner part of the commercial refrigeration. Of course, the length of the new capillary can be calculated by the pressure degree, but it is not necessary. It is found that the original commercial refrigeration capillary is cut short during maintenance. As long as it does not exceed 50 cm, the refrigeration performance will not be affected.
(2) Which models need to be equipped with a new capillary. For models without an evaporator interface box on the back of the commercial refrigeration, because the capillary cannot be welded to the evaporator nozzle, the original capillary must be thrown away and a new capillary must be installed.
