Mounting procedure
For dew proofing, mount a TKL insulation cover (our company’s model: TKL-SH, TKL-DH)
on the Pipe Support.

.2 Place an insulation joint adhesive tape (our company’ s
model: JTA) around the joint between the insulation cover
and the insulation material of the piping, overlapping it at
least 10 mm on the circumference. [Fig. 8]
.3Place an adhesive tape (our company’ s model: HF, HV, HR) around the joint of the insulation cover
on the base bracket to prevent the joint from opening. [Fig. 9]
Clean and remove all dusts and stains from the surface where the insulation
joint adhesive tape is placed.
（Note）
When placing the insulation joint adhesive tape at the edge of the T-portion of
the insulation cover, use your hand to press the tape wrinkles and push the
tape into the embossed shape (concave and convex shapes) so that the tape
adheres tightly to the material.
（Note）

For customers
●Be sure to read this instruction manual carefully and then install
the product properly.
●Be sure to hand this instruction manual to the customer.
●This instruction manual is valid only in Japan.
For installation contractors
●If there is a possibility of damage to the elbow at the uptake or downtake part of vertical piping, use an
expansion elbow (expansion loop, expansion offset, etc.) to absorb thermal expansion and contraction of
the copper tube.
●Make sure that the fixation band size matches the copper tube size before use.
●Fixation bands cannot be reused as they are deformed when opened after they are closed once.
●Do not use strap bolts as these are not strong enough.
●Always use a dedicated TKL base bracket for installation.

Mounting procedure
（Note）Use commercially available M10 bolts, nuts and washers. (Use a washer also for protecting the paint)
（Note）The mounting frame, on which the base bracket is mounted (model: TKL-B, TKL-U), must be designed carefully for the weight
of the vertical piping.
（Note）For mounting a wall-mounting base bracket (model: TLK-K), the wall must have sufficient strength.
Determining the mounting position of the Pipe Support at the center of the vertical piping length.
■Determining the mounting position
Mount a specific TKL base bracket (our company’s model: TKL-B, TKL-K, TKL-U) on the mounting
frame or the wall.
■Mounting the base bracket
1. Check before mounting

Warning
Always use a specific TKL base bracket for installation.
Do not use strap bolts as these are not strong enough.
Warning
Fixation bands cannot be reused as they are deformed and not capable of supporting the piping when
opened after they are closed once.
Make sure that the fixation band size matches the copper tube size before use.

For selecting a specific TKL base bracket (our company’s models: TKL-B, TKL-K,
TKL-U), see "Distance L (mm) between the center of copper tube and the mounting
frame (wall)" described in the Specifications (separate document).
※
Make sure that the hole of the
fixation band and the hole of the
base bracket are aligned before
starting to work. [Fig. 2]
(1)
If other pipes are located closely,
consider the tool size and determine
the work sequence.
(Tools may interfere with each other
depending on the sequence)
[Fig. 3]
(2)
Place one side of the fixation
band on the copper tube and
the base bracket, and check if
the holes are aligned correctly.
Base bracket
Interference
Press the side of the fixation band, which has a cutout, against the copper tube and close
the fixation band. When closing the band, make sure that the tabs located at the top and
bottom of the spacer go over the opposite spacer to secure them temporarily. [Fig. 4]
Tighten the hex bolts, included in the
package, starting from the center position
①. [Tightening torque: 12.5 N-m or more]
Tighten the upper and lower hex bolts ②alternately little by little until the upper and lower
tabs on the temporary nut fixation plate go over the other side. (When the tabs go over the
other side, tightening is completed) [Fig. 6]

For tightening the bolt and nut, if you turn the bolt, tightening can be completed at
a lower torque than turning the nut.
