Section 3 <br />Working with <br />Wirsbo AQUAPEX Tubing <br />Storing and Handling PEX <br />A Caution: <br />Do not store PEX tubing outdoors. <br />Keep PEX tubing in the original packaging until time <br />of installation. <br />Ensure that exposure to sunlight during installation does <br />0 not exceed the maximum recommended UV exposure time <br />of 30 days. <br />Uncoiling PEX <br />We recommend the Uponor Select Uncoiler (E6062000), Uponor Compact <br />Select Uncoiler (E6063000) or Uponor Tube Uncoiler (E6061000) to <br />facilitate convenient uncoiling of PEX tubing. If one is not available, <br />construct a suitable uncoiler. <br />Bending PEX <br />The minimum bend radius of Wirsbo AQUAPEX tubing is six times the <br />outside diameter. <br />Bend supports are available for %e', Yz; %" and 1 " Wirsbo AQUAPEX <br />tubing to facilitate 90 -degree rigid bends. <br />Reforming Kinked Tubing <br />If the tubing is kinked and hinders flow, repairs can be made easily. <br />1. Make sure the system is not pressurized. <br />2. Straighten the kinked portion of the tubing. <br />3. Heat the kinked area to approximately 265°F with an electric heat gun <br />(approximately 450 watts of power). Apply the heat evenly until the <br />tubing returns to its original size and shape. Do not use an open flame. <br />4. Let the repaired Wirsbo AQUAPEX tubing cool undisturbed to room <br />temperature. When the tubing returns to its opaque appearance, the <br />repair is complete. <br />ACaution: Do not allow the temperature of the tubing surface <br />to exceed 338°F. Do not apply direct flame to Wirsbo <br />AQUAPEX tubing. <br />Section 3 - Working with Wirsbo AQUAPEX Tubing uponor <br />
