Samsung AP0AS0ANXSG Refrigerant piping work, Connecting the pipes, Removing the connection pipe

Refrigerant piping work

	• When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor before
WARNING	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.

ffTry 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.

ffThe piping length between the outdoor unit and the indoor unit may not exceed the allowable piping length and height difference.

ffUse only certified refrigerant pipe and follow the installation method.

ffAfter 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 R22 refrigerant.

ffUse clean refrigerant pipe with no harmful ion, oxide, dust, iron content or moisture inside pipe.

Connecting the pipes

1.There 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.

• Do not use a hammer, but use a cutter to cut the notch.

2.Pipe installation condition may vary depending on the installation location. Therefore, use indoor and outdoor unit elbow pipe connector to install the pipe if necessary.

-- Allowable pipe length: Maximum 50m

-- Allowable pipe height difference: Maximum 20~30m

-- Make sure that there are less than 10 bending points in a pipe.

-- During initial installation, fill the additional refrigerant if the pipe length exceeds 5 m. -- For every 1 m of exceeding pipe length, fill additional refrigerant as stated below.

Model		Refrigerant amount
	Basic (g)		Additional (g/m)
AP0AS0A✴✴✴	6,500		80
AP80S0A✴✴✴	4,500		80

Ex) If total piping length is 30 m,

6,500 g (standard filling amount for 5 m pipe): Factory default (AP0AS0A✴✴✴)

2,000 g {80 g/m x (30 m – 5 m)}: Additional refrigerant amount (Fill during the installation)

8,500 g: Total amount of refrigerant filling
