3. REFRIGERANT PIPING CONNECTION
Safety Precautions
• All field piping must be completed by a licensed technician and must comply with
the local and national regulations.
• When the air conditioner is installed in a small room, measures must be taken to
prevent the refrigerant concentration in the room from exceeding the safety limit
in the event of refrigerant leakage. If the refrigerant leaks and its concentration
exceeds its proper limit, hazards due to lack of oxygen may result.
• When installing the refrigeration system, ensure that air, dust, moisture or foreign
substances do not enter the refrigerant circuit. Contamination in the system may
cause poor operating capacity, high pressure in the refrigeration cycle, explosion
or injury.
• Ventilate the area immediately if there is refrigerant leakage during the installa-
tion. Leaked refrigerant gas is both toxic and flammable. Ensure there is no refrig-
erant leakage after completing the installation work.
3.1. Notes On Pipe Length and Elevation
Ensure that the length of the refrigerant pipe, the number of bends, and the drop height between
the indoor and outdoor units meets the requirements.
3.2. Refrigerant Piping Connection Instructions
• DO NOT install the connecting pipe until both indoor and outdoor units have been
installed.
• Insulate both the gas and liquid piping to prevent water leakage.
Step1:
Cut pipes
When preparing refrigerant pipes, take extra care to cut and flare them properly. This will ensure
efficient operation and minimize the need for future maintenance.
1. Measure the distance between the indoor and outdoor units.
2. Using a pipe cutter, cut the pipe a little longer than the measured distance.
DO NOT deform pipe while cutting. Be extra careful not to damage, dent, or de-
form the pipe while cutting. This will drastically reduce the heating efficiency of
the unit.
