Y-Branch Kit Insulation

Each Y-branch kit comes with clam-shell type peel-and-stick insu-

lation jackets molded to fit the Y-branch fittings—one for the liquid

line, one for the vapor line.

• Check the fit of the Y-branch clam-shell insulation jacket after the

Y-branch is installed.

• Mark the pipe where the insulation jacket ends.

• Remove the jacket.

• Install field-provided insulation on the pipes first.

• Peel the adhesive glue protector slip and install the clam-shell

jacket over the fitting

No Pipe Size Substitutions

Use only the pipe size selected by the LATS Multi F pipe system design software or as conveyed in the product installation instructions.

Using a different size is prohibited and may result in a system malfunction or failure to work at all.

Below an obstacle.

Obstacles

When an obstacle, such as an I-beam or concrete T, is in the path

of the planned refrigerant pipe run, it is best practice to route the

pipe over the obstacle. If adequate space is not available to route

the insulated pipe over the obstacle, then route the pipe under the

obstacle. In either case, it is imperative the horizontal section of pipe

above or below the obstacle be a minimum of three (3) times greater

than the longest vertical rise (or fall) distance.
