INSTALLATION PARTS
Refrigerant piping work
WARNING
•When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor before removing the connection pipe.
•If the refrigerant pipe is not properly connected and the compressor works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high and it may cause explosion and injury.
•Try to keep the length of the refrigerant pipe as short as possible and make sure to minimize the height difference between the indoor and outdoor unit.
•The piping length between the outdoor unit and the indoor unit may not exceed the allowable piping length and height difference.
•Use only certified refrigerant pipe and follow the installation method.
•After completing the pipe installation, measure the length of the pipe to see whether or not you need to charge additional refrigerant. If you do, you must use
•Use clean refrigerant pipe with no harmful ion, oxide, dust, iron content or moisture inside pipe.
Connecting the pipes
1There are holes for refrigerant pipes on the left, right and rear side of the indoor unit and you may choose any one of the holes depending on your installation location. Choose a side for the easier pipe connection. You may connect the drain hose through the hole in the middle part of the rear side on the indoor unit.
CAUTION
•Do not use a hammer, but use a cutter to cut the notch.
