Refrigerant piping work
• When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor before
removing the connection pipe.
WARNING
• 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.
f Try to keep the length of the refrigerant pipe as short as possible and make sure to minimize the height difference
X
between the indoor and outdoor unit.
f The piping length between the outdoor unit and the indoor unit may not exceed the allowable piping length and height
X
difference.
f Use only certified refrigerant pipe and follow the installation method.
X
f After completing the pipe installation, measure the length of the pipe to see whether or not you need to charge
X
additional refrigerant. If you do, you must use R22 refrigerant.
f Use 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.
CAUTION
Holes for refrigerant pipe
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.
