Thermon Mechanical Tubing Bundle Bender - Manual (Page 2)

Receiving, Storing and Handling . . .
1. Inspect materials for damage incurred during shipping. Report
damages to carrier for settlement.
2. Identify correct tubing bender
for the tubing bundle being
installed. See Table 1 for bend
radius details.
3. Determine lengths and number
of fittings prior to uncoiling
Thermon tubing bundle since
repeated uncoiling and re-
coiling may “work harden”
the tubing or damage the bundle.
4. Position reel such that tubing bundle may be pulled from the
reel allowing installation to begin at an end-point working back
toward the reel.
5. To uncoil and straighten tubing bundles, anchor the loose end
of the tubing on a flat surface and roll the hand coil or shipping
reel. If additional straightening is needed, apply moderate
tension to the tubing bundles.
6. Wooden reels or spools of Thermon tubing bundles can be
placed on a pay-off tray as shown in Illustration A. To “pay-off”
tubing bundles, place the reel containing the tubing bundle on
one tray allowing the tubing to freely unspool from the bottom
of the reel.
7. Straighten tubing bundle by utilizing a counterspool located in
front of the reel containing the tubing (see Illustration A). The
counterspool should be located at a distance of 2-1/2 times
the diameter of the tubing bundle’s shipping reel. Include a
vertical offset of 8” to 10” (200 to 250mm) between the reel
elevations.

Bending Procedure . . .
Thermon tubing bundles should be installed so there is no strain
on any fittings after the installation is complete. The cross-sec-
tional area of the tubing bundle should not be flattened, kinked
or wrinkled. Refer to Table 1 for the minimum acceptable bend
radius for each type of Thermon tubing bundle. Use a properly
sized Thermon mechanical tubing bender to assure constant
radius bends where possible. For bend radius greater than 10
inch, use wooden reel or spool as shown below.
