CONNECTING REFRIGERANT PIPING LINES (Cont.)
STEPS FOR PREPARING REFRIGERANT PIPING LINES BEFORE CONNECTIONS (Cont.)
STEP (4): Mounting flare nuts on the
refrigerant piping lines
•
Mount the suction flare nut on the other side of
suction piping line.
•
Mount the liquid flare nut on the other side of
liquid piping line.
STEP (5): Flaring the Piping
•
Use flare tool to flare ends of both suction and
liquid piping lines slide a flare nut on to the tube
and modify the flare.
NOTES:
1) Good flare should have the following
characteristics :
•
Inside surface is glossy and smooth.
•
Edge is smooth and must not have any burrs
or imperfections.
•
Tapered sides are of uniform length.
2) Be sure to apply a sealing cap or waterproof tape
to prevent dust or water from getting into the
refrigeration piping lines before they are used.
Avoid incorrect flaring, which results in
damaged or cracked or inclined with
uneven thickness surface.
STEP (6):
Mounting flare nuts on the other
side of refrigerant piping lines
•
Mount the suction flare nut (Large nut) on the
other side of suction refrigerant piping line.
•
Mount the liquid flare nut (Small nut) on the other
side of liquid refrigerant piping line.
