3-4. Prepare the Tubing
● Material: Use C1220 phosphorous deoxidized copper as described in JIS H3300, “Copper and Copper Alloy Seamless Pipes
and Tubes.” (For tubes that are ø7/8"
(ø22.22 mm) or larger, use 1/2H material or H material. For all others use O material.)
● Tubing size
Use the tubing size indicated in the table below.
● When cutting the tubing, use a tube cutter, and be sure to remove any burrs.
(The same applies to distribution tubing (optional).)
● When bending the tubes, bend each tube using a radius that is at least 4 times the outer diameter of the tube.
When bending, use sufficient care to avoid crushing or damaging the tube.
● For flaring, use a flare tool, and be sure that flaring is performed correctly.
CAUTION
Use sufficient caution during preparation of the tubing. Seal the tube ends by means of caps
or taping to prevent dust, moisture, or other foreign substances from entering the tubes.
Refrigerant tubing (Existing tubing can be used.)
3-5. Connect the Tubing
