Section 3 <br /> Working with <br /> Wirsbo AQUAPEX Tubing <br /> Storing and Handling PEX <br /> ACaution: <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 UponorTube 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 %'; '/2; 3/<" 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 uponof <br />
