HEATED HOSE INSTALLATION
CAUTION!
The material delivery Heated Hoses are color coded
Red and Blue, allowing the user to recognize them. The Red cor-
responds to the Isocyanate (Iso, A) and the Blue to the Polyol
(Poly, R). To avoid connection errors, the Coupling Connections of
the Iso (A) and Poly (R) Heated Hoses are different sizes to ensure
correct orientation.
NOTE!
The material delivery Heated Hoses are capped at the
ends to prevent absorbing moisture.
Do not remove caps until
the Heated Hoses are going to be installed on the Proportioner.
1. Lay out all the Heated Hose assemblies end to end aligning the Iso “A” (red) and Poly
“R” (blue) and connect the respective Coupling Connections using the appropriate
sized open-end wrench after ensuring Heated Hose assemblies lay flat.
CAUTION!
Take care to not cross-thread or over-tighten
the Coupling Connections.
Thread seal tape or com-
pound is not recommended for these tapered seat Cou-
pling Connections.
2. Connect the material Heated Hoses to the outlets of the respective Exit Manifold
Assembly. Iso (A) Heated Hose to the JIC fitting on the left side of the Exit Manifold
Assembly and the Poly (R) Heated Hose to the JIC fitting on the left side of the Exit
Manifold Assembly. Ensure the Heated Hose assemblies lay flat.
3. Connect Air Hose Coupling Connections.
4. Connect the Heated Hose power wires to the “Fast-Lock” Connector (Part# KT-
00029A) coming from the Hose Heat Transformer as follows:
(a) Loosen the Socket Head Set Screw to allow insertion of the Heated Hose electrical
wire Terminal.
(b) Insert the Terminal into the “Fast-Lock” Connector Body.
(c) Securely tighten the Socket Head Set Screw.
(d) Install electrical tape around Connector Body.
NOTE!
A good practice is to add some dielectric grease
(Permatex 67VR or equivalent) to the outside of the
Terminal, where the electrical connection is made, prior
to insertion.
5. Repeat the above steps to connect the “Fast-Lock” Connectors that you will find on
all Heated Hose power wire.
