3-4. Prepare the Tubing
●
Material: Use seamless phosphorous deoxidized copper tube for refrigeration. Wall thickness shall comply with the applicable
legislation. The minimal wall thickness must be in accordance with the table below.
●
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
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.
