INABA DENKO TK Series User manual

Instruction manual
for the TK Series Vertical Lineset support system

NOTES:
Consult Marketair for further details.
1. This product is designed for use with linesets up to 165 feet (50
meters) high. Heights above this will require a specially designed
expansion loop.
2. Use of the correct brazing material and procedures is critical to
ensure that the load bearing capability of the TK fitting is not
compromised.
Determine the position of a fixed midpoint along the length of the
vertical lineset pipe length. This acts as a fulcrum to direct the thermal
expansion and contraction upwards and downwards from the midpoint,
supporting the weight of the lineset and reducing the load on the fitting
at the lowest floor by 50%.
(Drawing1)
Use only on vertical risers of 165 feet or less. For use on vertical risers over 165 feet, special
configurations are required, consult Marketair for details.

Before brazing the copper pipe support ferrule onto the lineset pipe,
first remove the insulation around the work area for 6” in both directions.

If attaching bracket to a structural steel
member use a 3/8” galvanized bolt and
nut, and ensure that the assembly can
support the weight of the lineset.
If attaching bracket to concrete,
masonary or block wall, use the TK-K
bracket and ensure it is firmly anchored.

Check for mounting position of Pipe Support Ferrule
Place ferrule around pipe so size marking faces the installer
(drawing 3) and clamp it onto the pipe surface ensuring that
the centerline of the ferrule is aligned with the centerline of
the mounting bracket (drawing 4).
Check that mounting position of ferrule is correct by
temporarily fitting the fixing clamp around the ferrule
(drawing 5) to confirm that the mounting holes line up.
Remove fixing clamp before proceeding to next step.

TO AVOID POTENTIAL RISK OF EXPLOSION, NEVER BRAZE LINESET WHEN IT IS UNDER PRESSURE!
Use following procedure to securely braze pipe support ferrule onto
pipe using only hard solder (SILVER SOLDER).

Ensure that entire space between interior surface of ferrule and pipe surface is completely filled with
brazing material to eliminate possibility of water droplets forming in any crevices and possibly deforming

Check for integrity of brazing material on all brazed surfaces of ferrule.
Cool down brazed ferrule assembly with damp cloth.
Filled brazing material may flow downwards when heat is applied to an adjacent section,
In this case, rebraze affected part.
After cooling ferrule, attach fixing clamp around ferrule and attach
to mounting bracket (drawing 16).
