SPLIT-TYPE ROOM AIR CONDITIONER
CAUTION
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.
Remove PVC tape from ends of pipe when ready to perform
flaring work.
Clamp flare form on the end of the pipe.
The end of the pipe must extend beyond the edge of the flare
form in accordance with the dimensions shown in the table
below.
Place flaring tool onto the form.
Turn the handle of the flaring tool clockwise until the pipe is
fully flared.
Remove the flaring tool and flare form, then inspect the end of
the pipe for cracks and even flaring.
Step 2: Remove burrs
Burrs can affect the air-tight seal of refrigerant piping
connection. They must be completely removed.
Hold the pipe at a downward angle to prevent burrs from falling
into the pipe.
Using a reamer or de burring tool, remove all burrs from the cut
section of the pipe.
Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtightseal.
After removing burrs from cut pipe, seal the ends with PVC tape
to prevent foreign materials from entering the pipe.
Sheath the pipe with insulating material.
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. See Fig. 5.3 .
