Connection instructions –
Refrigerant piping
CAUTION
• The branching pipe must be installed horizontally.
An angle of more than 10° may cause malfunction.
• 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.
Step 1: Cut pipes
When preparing refrigerant pipes, take extra care to cut and
flare them properly. This will ensure efficient operation and
minimise 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.
3. Make sure that the pipe is cut at a perfect 90° angle.
DO NOT DEFORM PIPE
WHILE CUTTING
Be extra careful not to damage, dent, or deform the
pipe while cutting. This will drastically reduce the heating
efficiency of the unit.
Step 2: Remove burrs
Burrs can affect the air-tight seal of refrigerant piping
connection. They must be completely removed.
1. Hold the pipe at a downward angle to prevent burrs from
falling into the pipe.
2. Using a reamer or deburring tool, remove all burrs from the
cut section of the pipe.
Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtight seal.
1. After removing burrs from cut pipe, seal the ends with PVC
tape to prevent foreign materials from entering the pipe.
2. Sheath the pipe with insulating material.
3. Place flare nuts on both ends of pipe. Make sure they are
facing in the right direction, because you can’t put them on
or change their direction after flaring.
4. Remove PVC tape from ends of pipe when ready to
perform flaring work.
5. Clamp flare form on the end of the pipe. The end of the
pipe must extend beyond the flare form.
6. Place flaring tool onto the form.
7. Turn the handle of the flaring tool clockwise until the pipe is
fully flared. Flare the pipe in accordance with the dimensions.
