Mounting procedure

4 Mounting an insulation cover (for dew proofing)■

For dew proofing, mount a TKL insulation cover (our company’s model: TKL-SH, TKL-DH)
on the Pipe Support.
1 . With reference to [Fig. 7], cut the end of the insulation cover (dimension (1)).
※ A gap plug is included in the package of TKL insulation cover (TKL-6SH/6DH〜14SH/14DH).
(This is not required for TKL-3K〜5K, and it is not included in the package of TKL-3SH/3DH〜5SH/5DH)[Fig. 7] For TKL-B/TKL-K

● If there is a possibility of damage to the elbow at the uptake or downtake part of vertical piping, use anexpansion elbow (expansion loop, expansion offset, etc.) to absorb thermal expansion and contraction of
the copper tube.
● Always use a dedicated TKL base bracket for installation.

Warning（Note）

Clean and remove all dusts and stains from the surface where the insulation
joint adhesive tape is placed.

[Fig. 8]Insulation material■ Note ※The product may not achieve its expected functions or performance if the following instructions
are not observed.

A pipe support is required at each floor/level. Use a flexible piping band (model: HBR) for supporting the piping.
Apply ultraviolet shielding measures for outdoor use. Or, the insulation material may deteriorate.

Mounting procedure

1 Determining the mounting position■

Determining the mounting position of the Pipe Support at the center of the vertical piping length.
Warning

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.

1 2. Temporary fixation of the fixation band
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 andbottom of the spacer go over the opposite spacer to secure them temporarily. [Fig. 4][Fig. 4]2 Mounting the base bracket■Mount a specific TKL base bracket (our company’s model: TKL-B, TKL-K, TKL-U) on the mounting
frame or the wall.
WarningFixation bandwith a cutout

Always use a specific TKL base bracket for installation.
Do not use strap bolts as these are not strong enough.

1. Check before mounting➡

Nut(commercial product)（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 weightof the vertical piping.
（Note）For mounting a wall-mounting base bracket (model: TLK-K), the wall must have sufficient strength.
